Traversing the vehicle transportation network may include traversing one or more distinct vehicle operational scenarios, such as pedestrian scenarios, intersection scenarios, lane change scenarios, or any other vehicle operational scenario or combination of vehicle operational scenarios.

[0020] An autonomous vehicle may traverse a current distinct vehicle operational scenario based on a policy or solution for a model, such as a Partially Observable Markov Decision Process (POMDP) model, of a respective distinct vehicle operational scenario. The autonomous vehicle may have limited resource availability for identifying respective distinct vehicle operational scenarios, and for solving corresponding models of the distinct vehicle operational scenarios. The autonomous vehicle may electronically communicate with an external centralized shared scenario-specific operational control management device to identify distinct vehicle operational scenarios and to identify corresponding policy data for respective models of the distinct vehicle operational scenarios.

[0021] The centralized shared scenario-specific operational control management device may maintain vehicle data and vehicle transportation network data including distinct vehicle operational scenario data, which may include data defining or describing various distinct vehicle operational scenarios, experience data generated by respective vehicles traversing corresponding distinct vehicle operational scenarios, model data modeling the respective distinct vehicle operational scenarios, policy data including policies or solutions for the respective models, or any other data or combination of data that may be used for centralized shared scenario- specific operational control management.

[0022] The centralized shared scenario-specific operational control management device may receive experience data, policy data, or both generated by vehicles traversing the vehicle transportation network, and may integrate the received data with previously stored shared scenario-specific operational control management data, which may include processing the data to validate and compact the data. The centralized shared scenario-specific operational control management device may distribute policy data to respective autonomous vehicles for use in traversing corresponding distinct vehicle operational scenarios. The centralized shared scenario-specific operational control management device may distribute the experience data to respective autonomous vehicles that have available resources for generating corresponding policy data.

Although shown as a single unit in FIG. 2, an access point may include any number of interconnected elements.

[0048] The vehicle 2100 may communicate with the communications network 2300 via a satellite 2350, or other non-terrestrial communication device. The satellite 2350, which may include a computing device, may be configured to communicate with a vehicle 2100, with a communication network 2300, with one or more communication devices 2400, or with a combination thereof via one or more communication links 2320/2360. Although shown as a single unit in FIG. 2, a satellite may include any number of interconnected elements.

[0049] An electronic communication network 2300 may be any type of network configured to provide for voice, data, or any other type of electronic communication. For example, the electronic communication network 2300 may include a local area network (LAN), a wide area network (WAN), a virtual private network (VPN), a mobile or cellular telephone network, the Internet, or any other electronic communication system. The electronic communication network 2300 may use a communication protocol, such as the transmission control protocol (TCP), the user datagram protocol (UDP), the internet protocol (IP), the real-time transport protocol (RTP) the HyperText Transport Protocol (HTTP), or a combination thereof. Although shown as a single unit in FIG. 2, an electronic communication network may include any number of interconnected elements.

[0050] The vehicle 2100 may identify a portion or condition of the vehicle transportation network 2200. For example, the vehicle 2100 may include one or more on- vehicle sensors 2105, such as sensor 1360 shown in FIG. 1, which may include a speed sensor, a wheel speed sensor, a camera, a gyroscope, an optical sensor, a laser sensor, a radar sensor, a sonic sensor, or any other sensor or device or combination thereof capable of determining or identifying a portion or condition of the vehicle transportation network 2200. The sensor data may include lane line data, remote vehicle location data, or both.

[0051] The vehicle 2100 may traverse a portion or portions of one or more vehicle transportation networks 2200 using information communicated via the network 2300, such as information representing the vehicle transportation network 2200, information identified by one or more on-vehicle sensors 2105, or a combination thereof.

[0052] Although, for simplicity, FIG. 2 shows two vehicles 2100, 2110, one vehicle transportation network 2200, one electronic communication network 2300, and one communication device 2400, any number of vehicles, networks, or computing devices may be used. The vehicle transportation and communication system 2000 may include devices, units, or elements not shown in FIG. 2. Although the vehicle 2100 is shown as a single unit, a vehicle may include any number of interconnected elements.

[0053] Although the vehicle 2100 is shown communicating with the communication device 2400 via the network 2300, the vehicle 2100 may communicate with the

communication device 2400 via any number of direct or indirect communication links. For example, the vehicle 2100 may communicate with the communication device 2400 via a direct communication link, such as a Bluetooth communication link.

[0054] In some embodiments, a vehicle 2100/2210 may be associated with an entity 2500/2510, such as a driver, operator, or owner of the vehicle. In some embodiments, an entity 2500/2510 associated with a vehicle 2100/2110 may be associated with one or more personal electronic devices 2502/2504/2512/2514, such as a smartphone 2502/2512 or a computer 2504/2514. In some embodiments, a personal electronic device

2502/2504/2512/2514 may communicate with a corresponding vehicle 2100/2110 via a direct or indirect communication link. Although one entity 2500/2510 is shown as associated with one vehicle 2100/2110 in FIG. 2, any number of vehicles may be associated with an entity and any number of entities may be associated with a vehicle.

[0055] FIG. 3 is a diagram of a portion of a vehicle transportation network in accordance with this disclosure. A vehicle transportation network 3000 may include one or more unnavigable areas 3100, such as a building, one or more partially navigable areas, such as parking area 3200, one or more navigable areas, such as roads 3300/3400, or a combination thereof. In some embodiments, an autonomous vehicle, such as the vehicle 1000 shown in FIG. 1, one of the vehicles 2100/2110 shown in FIG. 2, a semi- autonomous vehicle, or any other vehicle implementing autonomous driving, may traverse a portion or portions of the vehicle transportation network 3000.

[0056] The vehicle transportation network 3000 may include one or more interchanges 3210 between one or more navigable, or partially navigable, areas 3200/3300/3400. For example, the portion of the vehicle transportation network 3000 shown in FIG. 3 includes an interchange 3210 between the parking area 3200 and road 3400. The parking area 3200 may include parking slots 3220.

[0057] A portion of the vehicle transportation network 3000, such as a road 3300/3400, may include one or more lanes 3320/3340/3360/3420/3440 and may be associated with one or more directions of travel, which are indicated by arrows in FIG. 3.

[0058] A vehicle transportation network, or a portion thereof, such as the portion of the vehicle transportation network 3000 shown in FIG. 3, may be represented as vehicle transportation network data. For example, vehicle transportation network data may be expressed as a hierarchy of elements, such as markup language elements, which may be stored in a database or file. For simplicity, the figures herein depict vehicle transportation network data representing portions of a vehicle transportation network as diagrams or maps; however, vehicle transportation network data may be expressed in any computer-usable form capable of representing a vehicle transportation network, or a portion thereof. The vehicle transportation network data may include vehicle transportation network control information, such as direction of travel information, speed limit information, toll information, grade information, such as inclination or angle information, surface material information, aesthetic information, defined hazard information, or a combination thereof.

[0059] The vehicle transportation network may be associated with, or may include, a pedestrian transportation network. For example, FIG. 3 includes a portion 3600 of a pedestrian transportation network, which may be a pedestrian walkway. Although not shown separately in FIG. 3, a pedestrian navigable area, such as a pedestrian crosswalk, may correspond with a navigable area, or a partially navigable area, of a vehicle transportation network.

[0060] A portion, or a combination of portions, of the vehicle transportation network may be identified as a point of interest or a destination. For example, the vehicle transportation network data may identify a building, such as the unnavigable area 3100, and the adjacent partially navigable parking area 3200 as a point of interest, a vehicle may identify the point of interest as a destination, and the vehicle may travel from an origin to the destination by traversing the vehicle transportation network. Although the parking area 3200 associated with the unnavigable area 3100 is shown as adjacent to the unnavigable area 3100 in FIG. 3, a destination may include, for example, a building and a parking area that is physically or geospatially non-adjacent to the building.

[0061] Identifying a destination may include identifying a location for the destination, which may be a discrete uniquely identifiable geolocation. For example, the vehicle transportation network may include a defined location, such as a street address, a postal address, a vehicle transportation network address, a GPS address, or a combination thereof for the destination.

[0062] A destination may be associated with one or more entrances, such as the entrance 3500 shown in FIG. 3. The vehicle transportation network data may include defined entrance location information, such as information identifying a geolocation of an entrance associated with a destination.

[0063] A destination may be associated with one or more docking locations, such as the docking location 3700 shown in FIG. 3. A docking location 3700 may be a designated or undesignated location or area in proximity to a destination at which an autonomous vehicle may stop, stand, or park such that docking operations, such as passenger loading or unloading, may be performed.

[0064] The vehicle transportation network data may include docking location

information, such as information identifying a geolocation of one or more docking locations 3700 associated with a destination. Although not shown separately in FIG. 3, the docking location information may identify a type of docking operation associated with a docking location 3700. For example, a destination may be associated with a first docking location for passenger loading and a second docking location for passenger unloading. Although an autonomous vehicle may park at a docking location, a docking location associated with a destination may be independent and distinct from a parking area associated with the destination.

[0065] FIG. 4 is a diagram of an example of an autonomous vehicle operational management system 4000 in accordance with embodiments of this disclosure. The autonomous vehicle operational management system 4000 may be implemented in an autonomous vehicle, such as the vehicle 1000 shown in FIG. 1, one of the vehicles 2100/2110 shown in FIG. 2, a semi-autonomous vehicle, or any other vehicle implementing autonomous driving.

[0066] The autonomous vehicle may traverse a vehicle transportation network, or a portion thereof, which may include traversing distinct vehicle operational scenarios. A distinct vehicle operational scenario may include any distinctly identifiable set of operative conditions that may affect the operation of the autonomous vehicle within a defined spatiotemporal area, or operational environment, of the autonomous vehicle. For example, a distinct vehicle operational scenario may be based on a number or cardinality of roads, road segments, or lanes that the autonomous vehicle may traverse within a defined spatiotemporal distance. In another example, a distinct vehicle operational scenario may be based on one or more traffic control devices that may affect the operation of the autonomous vehicle within a defined spatiotemporal area, or operational environment, of the autonomous vehicle. In another example, a distinct vehicle operational scenario may be based on one or more identifiable rules, regulations, or laws that may affect the operation of the autonomous vehicle within a defined spatiotemporal area, or operational environment, of the autonomous vehicle. In another example, a distinct vehicle operational scenario may be based on one or more identifiable external objects that may affect the operation of the autonomous vehicle within a defined spatiotemporal area, or operational environment, of the autonomous vehicle.

[0067] For simplicity and clarity, similar vehicle operational scenarios may be described herein with reference to vehicle operational scenario types or classes. A type or class of a vehicle operation scenario may refer to a defined pattern or a defined set of patterns of the scenario. For example, intersection scenarios may include the autonomous vehicle traversing an intersection, pedestrian scenarios may include the autonomous vehicle traversing a portion of the vehicle transportation network that includes, or is within a defined proximity of, one or more pedestrians, such as wherein a pedestrian is crossing, or approaching, the expected path of the autonomous vehicle; lane-change scenarios may include the autonomous vehicle traversing a portion of the vehicle transportation network by changing lanes; merge scenarios may include the autonomous vehicle traversing a portion of the vehicle transportation network by merging from a first lane to a merged lane; pass-obstruction scenarios may include the autonomous vehicle traversing a portion of the vehicle transportation network by passing an obstacle or obstruction. Although pedestrian vehicle operational scenarios, intersection vehicle operational scenarios, lane-change vehicle operational scenarios, merge vehicle operational scenarios, and pass-obstruction vehicle operational scenarios are described herein, any other vehicle operational scenario or vehicle operational scenario type may be used.

[0068] As shown in FIG. 4, the autonomous vehicle operational management system 4000 includes an autonomous vehicle operational management controller 4100 (AVOMC), operational environment monitors 4200, and operation control evaluation modules 4300.

[0069] The AVOMC 4100, or another unit of the autonomous vehicle, may control the autonomous vehicle to traverse the vehicle transportation network, or a portion thereof. Controlling the autonomous vehicle to traverse the vehicle transportation network may include monitoring the operational environment of the autonomous vehicle, identifying or detecting distinct vehicle operational scenarios, identifying candidate vehicle control actions based on the distinct vehicle operational scenarios, controlling the autonomous vehicle to traverse a portion of the vehicle transportation network in accordance with one or more of the candidate vehicle control actions, or a combination thereof.

[0070] The AVOMC 4100 may receive, identify, or otherwise access, operational environment data representing an operational environment for the autonomous vehicle, or one or more aspects thereof. The operational environment of the autonomous vehicle may include a distinctly identifiable set of operative conditions that may affect the operation of the autonomous vehicle within a defined spatiotemporal area of the autonomous vehicle, within a defined spatiotemporal area of an identified route for the autonomous vehicle, or a combination thereof. For example, operative conditions that may affect the operation of the autonomous vehicle may be identified based on sensor data, vehicle transportation network data, route data, or any other data or combination of data representing a defined or determined operational environment for the vehicle.

[0071] The operational environment data may include vehicle information for the autonomous vehicle, such as information indicating a geospatial location of the autonomous vehicle, information correlating the geospatial location of the autonomous vehicle to information representing the vehicle transportation network, a route of the autonomous vehicle, a speed of the autonomous vehicle, an acceleration state of the autonomous vehicle, passenger information of the autonomous vehicle, or any other information about the autonomous vehicle or the operation of the autonomous vehicle. The operational environment data may include information representing the vehicle transportation network proximate to an identified route for the autonomous vehicle, such as within a defined spatial distance, such as 300 meters, of portions of the vehicle transportation network along the identified route, which may include information indicating the geometry of one or more aspects of the vehicle transportation network, information indicating a condition, such as a surface condition, of the vehicle transportation network, or any combination thereof. The operational environment data may include information representing the vehicle transportation network proximate to the autonomous vehicle, such as within a defined spatial distance of the autonomous vehicle, such as 300 meters, which may include information indicating the geometry of one or more aspects of the vehicle transportation network, information indicating a condition, such as a surface condition, of the vehicle transportation network, or any combination thereof. The operational environment data may include information representing external objects within the operational environment of the autonomous vehicle, such as information representing pedestrians, non-human animals, non-motorized transportation devices, such as bicycles or skateboards, motorized transportation devices, such as remote vehicles, or any other external object or entity that may affect the operation of the autonomous vehicle.

[0072] Aspects of the operational environment of the autonomous vehicle may be represented within respective distinct vehicle operational scenarios. For example, the relative orientation, trajectory, expected path, of external objects may be represented within respective distinct vehicle operational scenarios. In another example, the relative geometry of the vehicle transportation network may be represented within respective distinct vehicle operational scenarios.

[0073] As an example, a first distinct vehicle operational scenario may correspond to a pedestrian crossing a road at a crosswalk, and a relative orientation and expected path of the pedestrian, such as crossing from left to right for crossing from right to left, may be represented within the first distinct vehicle operational scenario. A second distinct vehicle operational scenario may correspond to a pedestrian crossing a road by jaywalking, and a relative orientation and expected path of the pedestrian, such as crossing from left to right for crossing from right to left, may be represented within the second distinct vehicle operational scenario.

[0074] The autonomous vehicle may traverse multiple distinct vehicle operational scenarios within an operational environment, which may be aspects of a compound vehicle operational scenario. The autonomous vehicle operational management system 4000 may operate or control the autonomous vehicle to traverse the distinct vehicle operational scenarios subject to defined constraints, such as safety constraints, legal constraints, physical constraints, user acceptability constraints, or any other constraint or combination of constraints that may be defined or derived for the operation of the autonomous vehicle.

[0075] The AVOMC 4100 may monitor the operational environment of the autonomous vehicle, or defined aspects thereof. Monitoring the operational environment of the autonomous vehicle may include identifying and tracking external objects, identifying distinct vehicle operational scenarios, or a combination thereof. For example, the AVOMC 4100 may identify and track external objects with the operational environment of the autonomous vehicle. Identifying and tracking the external objects may include identifying spatiotemporal locations of respective external objects, which may be relative to the autonomous vehicle, identifying one or more expected paths for respective external objects, which may include identifying a speed, a trajectory, or both, for an external object. For simplicity and clarity, descriptions of locations, expected locations, paths, expected paths, and the like herein may omit express indications that the corresponding locations and paths refer to geospatial and temporal components; however, unless expressly indicated herein, or otherwise unambiguously clear from context, the locations, expected locations, paths, expected paths, and the like described herein may include geospatial components, temporal components, or both. Monitor the operational environment of the autonomous vehicle may include using operational environment data received from the operational environment monitors 4200.

[0076] The operational environment monitors 4200 may include scenario-agnostic monitors, scenario-specific monitors, or a combination thereof. A scenario-agnostic monitor, such as a blocking monitor 4210, may monitor the operational environment of the autonomous vehicle, generate operational environment data representing aspects of the operational environment of the autonomous vehicle, and output the operational environment data to one or more scenario-specific monitor, the AVOMC 4100, or a combination thereof. A scenario-specific monitor, such as a pedestrian monitor 4220, an intersection monitor 4230, a lane-change monitor 4240, a merge monitor 4250, or a forward obstruction monitor 4260, may monitor the operational environment of the autonomous vehicle, generate operational environment data representing scenario-specific aspects of the operational environment of the autonomous vehicle, and output the operational environment data to one or more scenario- specific operation control evaluation modules 4300, the AVOMC 4100, or a combination thereof. For example, the pedestrian monitor 4220 may be an operational environment monitor for monitoring pedestrians, the intersection monitor 4230 may be an operational environment monitor for monitoring intersections, the lane-change monitor 4240 may be an operational environment monitor for monitoring lane-changes, the merge monitor 4250 may be an operational environment monitor for merges, and the forward obstruction monitor 4260 may be an operational environment monitor for monitoring forward obstructions. An operational environment monitor 4270 is shown using broken lines to indicate that the autonomous vehicle operational management system 4000 may include any number of operational environment monitors 4200.

[0077] An operational environment monitor 4200 may receive, or otherwise access, operational environment data, such as operational environment data generated or captured by one or more sensors of the autonomous vehicle, vehicle transportation network data, vehicle transportation network geometry data, route data, or a combination thereof. For example, the pedestrian monitor 4220 may receive, or otherwise access, information, such as sensor data, which may indicate, correspond to, or may otherwise be associated with, one or more pedestrians in the operational environment of the autonomous vehicle. An operational environment monitor 4200 may associate the operational environment data, or a portion thereof, with the operational environment, or an aspect thereof, such as with an external object, such as a pedestrian, a remote vehicle, or an aspect of the vehicle transportation network geometry.

[0078] An operational environment monitor 4200 may generate, or otherwise identify, information representing one or more aspects of the operational environment, such as with an external object, such as a pedestrian, a remote vehicle, or an aspect of the vehicle transportation network geometry, which may include filtering, abstracting, or otherwise processing the operational environment data. An operational environment monitor 4200 may output the information representing the one or more aspects of the operational environment to, or for access by, the AVOMC 4100, such by storing the information representing the one or more aspects of the operational environment in a memory, such as the memory 1340 shown in FIG. 1, of the autonomous vehicle accessible by the AVOMC 4100, sending the information representing the one or more aspects of the operational environment to the AVOMC 4100, or a combination thereof. An operational environment monitor 4200 may output the operational environment data to one or more elements of the autonomous vehicle operational management system 4000, such as the AVOMC 4100. Although not shown in FIG. 4, a scenario-specific operational environment monitor 4220, 4230, 4240, 4250, 4260 may output operational environment data to a scenario-agnostic operational environment monitor, such as the blocking monitor 4210.

[0079] The pedestrian monitor 4220 may correlate, associate, or otherwise process the operational environment data to identify, track, or predict actions of one or more pedestrians. For example, the pedestrian monitor 4220 may receive information, such as sensor data, from one or more sensors, which may correspond to one or more pedestrians, the pedestrian monitor 4220 may associate the sensor data with one or more identified pedestrians, which may include may identifying a direction of travel, a path, such as an expected path, a current or expected velocity, a current or expected acceleration rate, or a combination thereof for one or more of the respective identified pedestrians, and the pedestrian monitor 4220 may output the identified, associated, or generated pedestrian information to, or for access by, the AVOMC 4100.

[0080] The intersection monitor 4230 may correlate, associate, or otherwise process the operational environment data to identify, track, or predict actions of one or more remote vehicles in the operational environment of the autonomous vehicle, to identify an

intersection, or an aspect thereof, in the operational environment of the autonomous vehicle, to identify vehicle transportation network geometry, or a combination thereof. For example, the intersection monitor 4230 may receive information, such as sensor data, from one or more sensors, which may correspond to one or more remote vehicles in the operational environment of the autonomous vehicle, the intersection, or one or more aspects thereof, in the operational environment of the autonomous vehicle, the vehicle transportation network geometry, or a combination thereof, the intersection monitor 4230 may associate the sensor data with one or more identified remote vehicles in the operational environment of the autonomous vehicle, the intersection, or one or more aspects thereof, in the operational environment of the autonomous vehicle, the vehicle transportation network geometry, or a combination thereof, which may include may identifying a current or expected direction of travel, a path, such as an expected path, a current or expected velocity, a current or expected acceleration rate, or a combination thereof for one or more of the respective identified remote vehicles, and intersection monitor 4230 may output the identified, associated, or generated intersection information to, or for access by, the AVOMC 4100.

[0081] The lane-change monitor 4240 may correlate, associate, or otherwise process the operational environment data to identify, track, or predict actions of one or more remote vehicles in the operational environment of the autonomous vehicle, such as information indicating a slow or stationary remote vehicle along the expected path of the autonomous vehicle, to identify one or more aspects of the operational environment of the autonomous vehicle, such as vehicle transportation network geometry in the operational environment of the autonomous vehicle, or a combination thereof geospatially corresponding to a lane- change operation. For example, the lane-change monitor 4240 may receive information, such as sensor data, from one or more sensors, which may correspond to one or more remote vehicles in the operational environment of the autonomous vehicle, one or more aspects of the operational environment of the autonomous vehicle in the operational environment of the autonomous vehicle or a combination thereof geospatially corresponding to a lane-change operation, the lane-change monitor 4240 may associate the sensor data with one or more identified remote vehicles in the operational environment of the autonomous vehicle, one or more aspects of the operational environment of the autonomous vehicle or a combination thereof geospatially corresponding to a lane-change operation, which may include may identifying a current or expected direction of travel, a path, such as an expected path, a current or expected velocity, a current or expected acceleration rate, or a combination thereof for one or more of the respective identified remote vehicles, and the lane-change monitor 4240 may output the identified, associated, or generated lane-change information to, or for access by, the AVOMC 4100.

[0082] The merge monitor 4250 may correlate, associate, or otherwise process the operational environment information to identify, track, or predict actions of one or more remote vehicles in the operational environment of the autonomous vehicle, to identify one or more aspects of the operational environment of the autonomous vehicle, such as vehicle transportation network geometry in the operational environment of the autonomous vehicle, or a combination thereof geospatially corresponding to a merge operation. For example, the merge monitor 4250 may receive information, such as sensor data, from one or more sensors, which may correspond to one or more remote vehicles in the operational environment of the autonomous vehicle, one or more aspects of the operational environment of the autonomous vehicle in the operational environment of the autonomous vehicle or a combination thereof geospatially corresponding to a merge operation, the merge monitor 4250 may associate the sensor data with one or more identified remote vehicles in the operational environment of the autonomous vehicle, one or more aspects of the operational environment of the autonomous vehicle or a combination thereof geospatially corresponding to a merge operation, which may include may identifying a current or expected direction of travel, a path, such as an expected path, a current or expected velocity, a current or expected acceleration rate, or a combination thereof for one or more of the respective identified remote vehicles, and the merge monitor 4250 may output the identified, associated, or generated merge information to, or for access by, the AVOMC 4100.

[0083] The forward obstruction monitor 4260 may correlate, associate, or otherwise process the operational environment information to identify one or more aspects of the operational environment of the autonomous vehicle geospatially corresponding to a forward pass-obstruction operation. For example, the forward obstruction monitor 4260 may identify vehicle transportation network geometry in the operational environment of the autonomous vehicle; the forward obstruction monitor 4260 may identify one or more obstructions or obstacles in the operational environment of the autonomous vehicle, such as a slow or stationary remote vehicle along the expected path of the autonomous vehicle or along an identified route for the autonomous vehicle; and the forward obstruction monitor 4260 may identify, track, or predict actions of one or more remote vehicles in the operational environment of the autonomous vehicle. The forward obstruction monitor 4250 may receive information, such as sensor data, from one or more sensors, which may correspond to one or more remote vehicles in the operational environment of the autonomous vehicle, one or more aspects of the operational environment of the autonomous vehicle in the operational environment of the autonomous vehicle or a combination thereof geospatially corresponding to a forward pass-obstruction operation, the forward obstruction monitor 4250 may associate the sensor data with one or more identified remote vehicles in the operational environment of the autonomous vehicle, one or more aspects of the operational environment of the autonomous vehicle or a combination thereof geospatially corresponding to the forward pass- obstruction operation, which may include may identifying a current or expected direction of travel, a path, such as an expected path, a current or expected velocity, a current or expected acceleration rate, or a combination thereof for one or more of the respective identified remote vehicles, and the forward obstruction monitor 4250 may output the identified, associated, or generated forward obstruction information to, or for access by, the AVOMC 4100.

[0084] The blocking monitor 4210 may receive operational environment data representing an operational environment, or an aspect thereof, for the autonomous vehicle. The blocking monitor 4210 may determine a respective probability of availability, or corresponding blocking probability, for one or more portions of the vehicle transportation network, such as portions of the vehicle transportation network proximal to the autonomous vehicle, which may include portions of the vehicle transportation network corresponding to an expected path of the autonomous vehicle, such as an expected path identified based on a current route of the autonomous vehicle. A probability of availability, or corresponding blocking probability, may indicate a probability or likelihood that the autonomous vehicle may traverse a portion of, or spatial location within, the vehicle transportation network safely, such as unimpeded by an external object, such as a remote vehicle or a pedestrian. The blocking monitor 4210 may determine, or update, probabilities of availability continually or periodically. The blocking monitor 4210 may communicate probabilities of availability, or corresponding blocking probabilities, to the AVOMC 4100.

[0085] The AVOMC 4100 may identify one or more distinct vehicle operational scenarios based on one or more aspects of the operational environment represented by the operational environment data. For example, the AVOMC 4100 may identify a distinct vehicle operational scenario in response to identifying, or based on, the operational environment data indicated by one or more of the operational environment monitors 4200. The distinct vehicle operational scenario may be identified based on route data, sensor data, or a combination thereof. For example, the AVOMC 4100 may identifying one or multiple distinct vehicle operational scenarios corresponding to an identified route for the vehicle, such as based on map data corresponding to the identified route, in response to identifying the route. Multiple distinct vehicle operational scenarios may be identified based on one or more aspects of the operational environment represented by the operational environment data. For example, the operational environment data may include information representing a pedestrian approaching an intersection along an expected path for the autonomous vehicle, and the AVOMC 4100 may identify a pedestrian vehicle operational scenario, an intersection vehicle operational scenario, or both.

[0086] The AVOMC 4100 may instantiate respective instances of one or more of the operation control evaluation modules 4300 based on one or more aspects of the operational environment represented by the operational environment data. The operation control evaluation modules 4300 may include scenario-specific operation control evaluation modules (SSOCEMs), such as a pedestrian-SSOCEM 4310, an intersection- SSOCEM 4320, a lane- change-SSOCEM 4330, a merge-SSOCEM 4340, a pass-obstruction-SSOCEM 4350, or a combination thereof. A SSOCEM 4360 is shown using broken lines to indicate that the autonomous vehicle operational management system 4000 may include any number of SSOCEMs 4300. For example, the AVOMC 4100 may instantiate an instance of a SSOCEM 4300 in response to identifying a distinct vehicle operational scenario. The AVOMC 4100 may instantiate multiple instances of one or more SSOCEMs 4300 based on one or more aspects of the operational environment represented by the operational environment data. For example, the operational environment data may indicate two pedestrians in the operational environment of the autonomous vehicle and the AVOMC 4100 may instantiate a respective instance of the pedestrian-SSOCEM 4310 for each pedestrian based on one or more aspects of the operational environment represented by the operational environment data.

[0087] The AVOMC 4100 may send the operational environment data, or one or more aspects thereof, to another unit of the autonomous vehicle, such as the blocking monitor 4210 or one or more instances of the SSOCEMs 4300. For example, the AVOMC 4100 may communicate the probabilities of availability, or corresponding blocking probabilities, received from the blocking monitor 4210 to respective instantiated instances of the

SSOCEMs 4300. The AVOMC 4100 may store the operational environment data, or one or more aspects thereof, such as in a memory, such as the memory 1340 shown in FIG. 1, of the autonomous vehicle.

[0088] Controlling the autonomous vehicle to traverse the vehicle transportation network may include identifying candidate vehicle control actions based on the distinct vehicle operational scenarios, controlling the autonomous vehicle to traverse a portion of the vehicle transportation network in accordance with one or more of the candidate vehicle control actions, or a combination thereof. For example, the AVOMC 4100 may receive one or more candidate vehicle control actions from respective instances of the SSOCEMs 4300. The AVOMC 4100 may identify a vehicle control action from the candidate vehicle control actions, and may control the vehicle, or may provide the identified vehicle control action to another vehicle control unit, to traverse the vehicle transportation network in accordance with the vehicle control action.

[0089] A vehicle control action may indicate a vehicle control operation or maneuver, such as accelerating, decelerating, turning, stopping, or any other vehicle operation or combination of vehicle operations that may be performed by the autonomous vehicle in conjunction with traversing a portion of the vehicle transportation network. For example, an ‘advance’ vehicle control action may include slowly inching forward a short distance, such as a few inches or a foot; an‘accelerate’ vehicle control action may include accelerating a defined acceleration rate, or at an acceleration rate within a defined range; a‘decelerate’ vehicle control action may include decelerating a defined deceleration rate, or at a deceleration rate within a defined range; a‘maintain’ vehicle control action may include maintaining current operational parameters, such as by maintaining a current velocity, a current path or route, or a current lane orientation; and a‘proceed’ vehicle control action may include beginning or resuming a previously identified set of operational parameters. Although some vehicle control actions are described herein, other vehicle control actions may be used. [0090] A vehicle control action may include one or more performance metrics. For example, a‘stop’ vehicle control action may include a deceleration rate as a performance metric. In another example, a‘proceed’ vehicle control action may expressly indicate route or path information, speed information, an acceleration rate, or a combination thereof as performance metrics, or may expressly or implicitly indicate that a current or previously identified path, speed, acceleration rate, or a combination thereof may be maintained. A vehicle control action may be a compound vehicle control action, which may include a sequence, combination, or both of vehicle control actions. For example, an‘advance’ vehicle control action may indicate a‘stop’ vehicle control action, a subsequent‘accelerate’ vehicle control action associated with a defined acceleration rate, and a subsequent‘stop’ vehicle control action associated with a defined deceleration rate, such that controlling the autonomous vehicle in accordance with the‘advance’ vehicle control action includes controlling the autonomous vehicle to slowly inch forward a short distance, such as a few inches or a foot.

[0091] The AVOMC 4100 may uninstantiate an instance of a SSOCEM 4300. For example, the AVOMC 4100 may identify a distinct set of operative conditions as indicating a distinct vehicle operational scenario for the autonomous vehicle, instantiate an instance of a SSOCEM 4300 for the distinct vehicle operational scenario, monitor the operative conditions, subsequently determine that one or more of the operative conditions has expired, or has a probability of affecting the operation of the autonomous vehicle below a defined threshold, and the AVOMC 4100 may uninstantiate the instance of the SSOCEM 4300.

[0092] The AVOMC 4100 may instantiate and uninstantiate instances of SSOCEMs 4300 based on one or more vehicle operational management control metrics, such as an

immanency metric, an urgency metric, a utility metric, an acceptability metric, or a combination thereof. An immanency metric may indicate, represent, or be based on, a spatial, temporal, or spatiotemporal distance or proximity, which may be an expected distance or proximity, for the vehicle to traverse the vehicle transportation network from a current location of the vehicle to a portion of the vehicle transportation network corresponding to a respective identified vehicle operational scenario. An urgency metric may indicate, represent, or be based on, a measure of the spatial, temporal, or spatiotemporal distance available for controlling the vehicle to traverse a portion of the vehicle transportation network

corresponding to a respective identified vehicle operational scenario. A utility metric may indicate, represent, or be based on, an expected value of instantiating an instance of a SSOCEM 4300 corresponding to a respective identified vehicle operational scenario. An acceptability metric may be a safety metric, such a metric indicating collision avoidance, a vehicle transportation network control compliance metric, such as a metric indicating compliance with vehicle transportation network rules and regulations, a physical capability metric, such as a metric indicating a maximum braking capability of the vehicle, a user defined metric, such as a user preference. Other metrics, or combinations of metrics may be used. A vehicle operational management control metric may indicate a defined rate, range, or limit. For example, an acceptability metric may indicate a defined target rate of deceleration, a defined range of deceleration rates, or a defined maximum rate of deceleration.

[0093] A SSOCEM 4300 may include one or more models of a respective distinct vehicle operational scenario. The autonomous vehicle operational management system 4000 may include any number of SSOCEMs 4300, each including models of a respective distinct vehicle operational scenario. A SSOCEM 4300 may include one or more models from one or more types of models. For example, a SSOCEM 4300 may include a Partially Observable Markov Decision Process (POMDP) model, a Markov Decision Process (MDP) model, a Classical Planning model, a Partially Observable Stochastic Game (POSG) model, a

Decentralized Partially Observable Markov Decision Process (Dec-POMDP) model, a Reinforcement Learning (RL) model, an artificial neural network model, or any other model of a respective distinct vehicle operational scenario. Each different type of model may have respective characteristics for accuracy and resource utilization. For example, a POMDP model for a defined scenario may have greater accuracy and greater resource utilization than an MDP model for the defined scenario. The models included in a SSOCEM 4300 may be ordered, such as hierarchically, such as based on accuracy. For example, a designated model, such as the most accurate model included in an SSOCEM 4300, may be identified as the primary model for the SSOCEM 4300 and other models included in the SSOCEM 4300 may be identified as secondary models.

[0094] In an example, one or more of the SSOCEMs 4300 may include a POMDP model, which may be a single-agent model. A POMDP model may model a distinct vehicle operational scenario, which may include modeling uncertainty, using a set of states (S), a set of actions (A), a set of observations (W), a set of state transition probabilities (T), a set of conditional observation probabilities (O), a reward function (R), or a combination thereof. A POMDP model may be defined or described as a tuple <S, A, W, T, O, R>.

[0095] A state from the set of states (S), may represent a distinct condition of respective defined aspects, such as external objects and traffic control devices, of the operational environment of the autonomous vehicle that may probabilistically affect the operation of the autonomous vehicle at a discrete temporal location. A respective set of states (S) may be defined for each distinct vehicle operational scenario. Each state (state space), from a set of states (S) may include one or more defined state factors. Although some examples of state factors for some models are described herein, a model, including any model described herein, may include any number, or cardinality, of state factors. Each state factor may represent a defined aspect of the respective scenario, and may have a respective defined set of values. Although some examples of state factor values for some state factors are described herein, a state factor, including any state factor described herein, may include any number, or cardinality, of values.

[0096] An action from the set of actions (A) may indicate an available vehicle control action at each state in the set of states (S). A respective set of actions may be defined for each distinct vehicle operational scenario. Each action (action space), from a set of actions (A) may include one or more defined action factors. Although some examples of action factors for some models are described herein, a model, including any model described herein, may include any number, or cardinality, of action factors. Each action factor may represent an available vehicle control action, and may have a respective defined set of values. Although some examples of action factor values for some action factors are described herein, an action factor, including any action factor described herein, may include any number, or cardinality, of values.

[0097] An observation from the set of observations (W) may indicate available observable, measurable, or determinable data for each state from the set of states (S). A respective set of observations may be defined for each distinct vehicle operational scenario. Each observation (observation space), from a set of observations (W) may include one or more defined observation factors. Although some examples of observation factors for some models are described herein, a model, including any model described herein, may include any number, or cardinality, of observation factors. Each observations factor may represent available observations, and may have a respective defined set of values. Although some examples of observation factor values for some observation factors are described herein, an observation factor, including any observation factor described herein, may include any number, or cardinality, of values.

[0098] A state transition probability from the set of state transition probabilities (T) may probabilistically represent changes to the operational environment of the autonomous vehicle, as represented by the set of states (S), responsive to the actions of the autonomous vehicle, as represented by the set of actions (A), which may be expressed as T: S x A x S [0, 1]. A respective set of state transition probabilities (T) may be defined for each distinct vehicle operational scenario. Although some examples of state transition probabilities for some models are described herein, a model, including any model described herein, may include any number, or cardinality, of state transition probabilities. For example, each combination of a state, an action, and a subsequent state may be associated with a respective state transition probability.

[0099] A conditional observation probability from the set of conditional observation probabilities (O) may represent probabilities of making respective observations (W) based on the operational environment of the autonomous vehicle, as represented by the set of states (S), responsive to the actions of the autonomous vehicle, as represented by the set of actions (A), which may be represented as O: A x S x W [0, 1]. A respective set of conditional observation probabilities (O) may be defined for each distinct vehicle operational scenario. Although some examples of state conditional observation probabilities for some models are described herein, a model, including any model described herein, may include any number, or cardinality, of conditional observation probabilities. For example, each combination of an action, a subsequent state, and an observation may be associated with a respective conditional observation probability.

[0100] The reward function (R) may determine a respective positive or negative (cost) value that may be accrued for each combination of state and action, which may represent an expected value of the autonomous vehicle traversing the vehicle transportation network from the corresponding state in accordance with the corresponding vehicle control action to the subsequent state, which may be expressed as R: S x A □.

[0101] For simplicity and clarity, the examples of values of a model, such as state factor values or observation factor values, described herein include categorical representations, such as {start, goal] or {short, long}. The categorical values may represent defined discrete values, which may be relative values. For example, a state factor representing a temporal aspect may have values from the set {short, long}; the value‘short’ may represent discrete values, such as a temporal distance, within, or less than, a defined threshold, such as three seconds, and the value‘long’ may represent discrete values, such as a temporal distance, of at least, such as equal to or greater than, the defined threshold. Defined thresholds for respective categorical values may be defined relative to associated factors. For example, a defined threshold for the set {short, long} for a temporal factor may be associated with a relative spatial location factor value and another defined threshold for the set { short, long } for the temporal factor may be associated with another relative spatial location factor value. Although categorical representations of factor values are described herein, other representations, or combinations of representations, may be used. For example, a set of temporal state factor values may be {short (representing values of less than three seconds), 4, 5, 6, long (representing values of at least 7 seconds) } .

[0102] In some embodiments, such as embodiments implementing a POMDP model, modeling an autonomous vehicle operational control scenario may include modeling occlusions. For example, the operational environment data may include information corresponding to one or more occlusions, such as sensor occlusions, in the operational environment of the autonomous vehicle such that the operational environment data may omit information representing one or more occluded external objects in the operational environment of the autonomous vehicle. For example, an occlusion may be an external object, such as a traffic signs, a building, a tree, an identified external object, or any other operational condition or combination of operational conditions capable of occluding one or more other operational conditions, such as external objects, from the autonomous vehicle at a defined spatiotemporal location. In some embodiments, an operational environment monitor 4200 may identify occlusions, may identify or determine a probability that an external object is occluded, or hidden, by an identified occlusion, and may include occluded vehicle probability information in the operational environment data output to the AVOMC 4100, and communicated, by the AVOMC 4100, to the respective SSOCEMs 4300.

[0103] The autonomous vehicle operational management system 4000 may include any number or combination of types of models. For example, the pedestrian-SSOCEM 4310, the intersection-SSOCEM 4320, the lane-change-SSOCEM 4330, the merge-SSOCEM 4340, and the pass-obstruction-SSOCEM 4350 may be POMDP models. In another example, the pedestrian-SSOCEM 4310 may be a MDP model and the intersection-SSOCEM 4320 may be a POMDP model. The AVOMC 4100 may instantiate any number of instances of the SSOCEMs 4300 based on the operational environment data.

[0104] Instantiating a SSOCEM 4300 instance may include identifying a model from the SSOCEM 4300, and instantiating an instance of the identified model. For example, a SSOCEM 4300 may include a primary model and a secondary model for a respective distinct vehicle operational scenario, and instantiating the SSOCEM 4300 may include identifying the primary model as a current model and instantiating an instance of the primary model.

Instantiating a model may include determining whether a solution or policy is available for the model. Instantiating a model may include determining whether an available solution or policy for the model is partially solved, or is convergent and solved. Instantiating a SSOCEM 4300 may include instantiating an instance of a solution or policy for the identified model for the SSOCEM 4300.

[0105] Solving a model, such as a POMDP model, may include determining a policy or solution, which may be a function, that maximizes an accrued reward, which may be determined by evaluating the possible combinations of the elements of the tuple, such as <S, A, W, T, O, R>, that defines the model. A policy or solution may identify or output a reward maximized, or optimal, candidate vehicle control action based on identified belief state data. The identified belief state data, which may be probabilistic, may indicate current state data, such as a current set of state values for the respective model, or a probability for the current set of state values, and may correspond with a respective relative temporal location. For example, solving a MDP model may include identifying a state from the set of states (S), identifying an action from the set of action (A), determining a subsequent, or successor, state from the set of states (S) subsequent to simulating the action subject to the state transition probabilities. Each state may be associated with a corresponding utility value, and solving the MDP model may include determining respective utility values corresponding to each possible combination of state, action, and subsequent state. The utility value of the subsequent state may be identified as the maximum identified utility value subject to a reward, or penalty, which may be a discounted reward, or penalty. The policy may indicate an action

corresponding to the maximum utility value for a respective state. Solving a POMDP model may be similar to solving the MDP model, except based on belief states, representing probabilities for respective states and subject to observation probabilities corresponding generating observations for respective states. Thus, solving the SSOCEM model includes evaluating the possible state-action-state transitions and updating respective belief states, such as using Bayes rule, based on respective actions and observations.

[0106] In some implementations, a model, such as a MDP model or a POMDP model, may reduce the resource utilization associated with solving the corresponding model by evaluating the states, belief states, or both, modeled therein to identify computations corresponding to the respective states, belief states, or both that may be omitted and omitting performing the identified computations, which may include obtaining or maintaining a measure of current quality, such as upper and lower bounds on utility for the respective state, belief state, or both. In some implementations, solving a model may include parallel processing, such as parallel processing using multiple processor cores or using multiple processors, which may include graphics processing units (GPUs). In some implementations, solving a model may include obtaining an approximation of the model, which may improve the efficiency of solving the model.

[0107] FIG. 5 is a flow diagram of an example of autonomous vehicle operational management 5000 in accordance with embodiments of this disclosure. Autonomous vehicle operational management 5000 may be implemented in an autonomous vehicle, such as the vehicle 1000 shown in FIG. 1, one of the vehicles 2100/2110 shown in FIG. 2, a semi- autonomous vehicle, or any other vehicle implementing autonomous driving. For example, an autonomous vehicle may implement an autonomous vehicle operational management system, such as the autonomous vehicle operational management system 4000 shown in FIG. 4.

[0108] As shown in FIG. 5, autonomous vehicle operational management 5000 includes implementing or operating the autonomous vehicle operational management system, including one or more modules or components thereof, which may include operating an autonomous vehicle operational management controller (AVOMC) 5100, such as the AVOMC 4100 shown in FIG. 4; operating operational environment monitors 5200, such as one or more of the operational environment monitors 4300 shown in FIG. 4; and operating a scenario-specific operational control evaluation module instance (SSOCEM instance) 5300, such as an instance of a SSOCEM 4300 shown in FIG. 4.

[0109] The AVOMC 5100 may monitor the operational environment of the autonomous vehicle, or defined aspects thereof, at 5110 to identify an operational environment, or an aspect thereof, of the autonomous vehicle. For example, operational environment monitors 5200 may monitor scenario- specific aspects of the operational environment and may send operational environment data representing the operational environment to the AVOMC 5100. Monitoring the operational environment of the autonomous vehicle may include identifying and tracking external objects at 5110, identifying distinct vehicle operational scenarios at 5120, or a combination thereof. For example, the AVOMC 5100, the operational environment monitors 5200, or both, may identify the operational environment data based on sensor data, vehicle data, route data, vehicle transportation network data, previously identified operational environment data, or any other available data, or combination of data, describing an aspect or aspects of the operational environment.

[0110] Identifying the operational environment may include identifying operational environment data representing the operational environment, or one or more aspects thereof. The operational environment data may include vehicle information for the autonomous vehicle, information representing the vehicle transportation network, or one or more aspects thereof, proximate to the autonomous vehicle, information representing external objects, or one or more aspects thereof, within the operational environment of the autonomous vehicle, along or proximate to a route identified for the autonomous vehicle, or a combination thereof. The sensor information may be processed sensor information, such as processed sensor information from a sensor information processing unit of the autonomous vehicle, which may receive sensor information from the sensor of the autonomous vehicle and may generate the processed sensor information based on the sensor information.

[0111] Identifying the operational environment data may include receiving information indicating one or more aspects of the operational environment from a sensor of the autonomous vehicle, such as the sensor 1360 shown in FIG. 1 or the on-vehicle sensors 2105 shown in FIG. 2. The sensor, or another unit of the autonomous vehicle, may store the sensor information in a memory, such as the memory 1340 shown in FIG. 1, of the autonomous vehicle and the AVOMC 5100 reading the sensor information from the memory.

[0112] Identifying the operational environment data may include identifying information indicating one or more aspects of the operational environment from vehicle transportation network data. For example, the AVOMC 5100 may read, or otherwise receive, vehicle transportation network data indicating that the autonomous vehicle is approaching an intersection, or otherwise describing a geometry or configuration of the vehicle transportation network proximate to the autonomous vehicle, such as within 300 meters of the autonomous vehicle.

[0113] Identifying the operational environment data at 5110 may include identifying information indicating one or more aspects of the operational environment from a remote vehicle or other remote device external to the autonomous vehicle. For example, the autonomous vehicle may receive, from a remote vehicle, via a wireless electronic

communication link, a remote vehicle message including remote vehicle information indicating remote vehicle geospatial state information for the remote vehicle, remote vehicle kinematic state information for the remote vehicle, or both.

[0114] Identifying the operational environment data may include identifying information indicating one or more aspects of the operational environment from route data representing an identified route for the autonomous vehicle. For example, the AVOMC 5100 may read, or otherwise receive, vehicle transportation network data representing an identified route, such as a route identified in response to user input, for the autonomous vehicle.

[0115] The AVOMC 5100 and the operational environment monitors 5200 may communicate to identify the operational environment information as indicated at 5110, 5112, and 5210. Alternatively, or in addition, the operational environment monitors 5200 may receive the operational environment data from another component of the autonomous vehicle, such as from a sensor of the autonomous vehicle or from another operational environment monitor 5200, or the operational environment monitors 5200 may read the operational environment data from a memory of the autonomous vehicle.

[0116] The AVOMC 5100 may detect or identify one or more distinct vehicle operational scenarios at 5120, such as based on one or more aspects of the operational environment represented by the operational environment data identified at 5110.

[0117] The AVOMC 5100 may instantiate a SSOCEM instance 5300 based on one or more aspects of the operational environment represented by the operational environment data at 5130, such as in response to identifying a distinct vehicle operational scenario at 5120. Although one SSOCEM instance 5300 is shown in FIG. 5, the AVOMC 5100 may instantiate multiple SSOCEM instances 5300 based on one or more aspects of the operational environment represented by the operational environment data identified at 5110, each SSOCEM instance 5300 corresponding to a respective distinct vehicle operational scenario detected at 5120, or a combination of a distinct external object identified at 5110 and a respective distinct vehicle operational scenario detected at 5120. Instantiating a SSOCEM instance 5300 at 5130 may include sending the operational environment data representing an operational environment for the autonomous vehicle to the SSOCEM instance 5300 as indicated at 5132. The SSOCEM instance 5300 may receive the operational environment data representing an operational environment for the autonomous vehicle, or one or more aspects thereof, at 5310. Instantiating a SSOCEM instance 5300 at 5130 may include identifying a model, such as a primary model or a secondary model, of the distinct vehicle operational scenario, instantiating an instance of the model, identifying a solution or policy

corresponding to the model, instantiating an instance of the solution or policy, or a combination thereof.

[0118] The operational environment monitors 5200 may include a blocking monitor, such as the blocking monitor 4210 shown in FIG. 4, which may determine a respective probability of availability (POA), or corresponding blocking probability, at 5220 for one or more portions of the vehicle transportation network, such as portions of the vehicle transportation network proximal to the autonomous vehicle, which may include portions of the vehicle transportation network corresponding to an expected path of the autonomous vehicle, such as an expected path identified based on a current route of the autonomous vehicle. The blocking monitor may send the probabilities of availability identified at 5220 to the SSOCEM instance 5300 at 5222. Alternatively, or in addition, the blocking monitor may store the probabilities of availability identified at 5220 in a memory of the autonomous vehicle. Although not expressly shown in FIG. 5, the blocking monitor may send the probabilities of availability identified at 5220 to the AVOMC 5100 at 5222 in addition to, or in alternative to, sending the probabilities of availability to the SSOCEM instance 5300. The SSOCEM instance 5300 may receive the probabilities of availability at 5320.

[0119] The SSOCEM instance 5300 may generate or identify a candidate vehicle control action at 5330. For example, the SSOCEM instance 5300 may generate or identify the candidate vehicle control action at 5330 in response to receiving the operational environment data 5310, receiving the probability of availability data at 5320, or both. For example, the instance of the solution or policy instantiated at 5310 for the model of the distinct vehicle operational scenario may output the candidate vehicle control action based on the operational environment data, the probability of availability data, or both. The SSOCEM instance 5300 may send the candidate vehicle control action identified at 5330 to the AVOMC 5100 at 5332. Alternatively, or in addition, the SSOCEM instance 5300 may store the candidate vehicle control action identified at 5330 in a memory of the autonomous vehicle.

[0120] The AVOMC 5100 may receive a candidate vehicle control action at 5140. For example, the AVOMC 5100 may receive the candidate vehicle control action from the SSOCEM instance 5300 at 5140. Alternatively, or in addition, the AVOMC 5100 may read the candidate vehicle control action from a memory of the autonomous vehicle.

[0121] The AVOMC 5100 may approve the candidate vehicle control action, or otherwise identify the candidate vehicle control action as a vehicle control action for controlling the autonomous vehicle to traverse the vehicle transportation network, at 5150. Approving a candidate vehicle control action at 5150 may include determining whether to traverse a portion of the vehicle transportation network in accordance with the candidate vehicle control action.

[0122] The AVOMC 5100 may control, or may provide the identified vehicle control action to another vehicle control unit, the autonomous vehicle to traverse the vehicle transportation network, or a portion thereof, at 5160 in accordance with the vehicle control action identified at 5150.

[0123] The AVOMC 5100 may identify an operational environment, or an aspect thereof, of the autonomous vehicle at 5170. Identifying an operational environment, or an aspect thereof, of the autonomous vehicle at 5170 may be similar to identifying the operational environment of the autonomous vehicle at 5110 and may include updating previously identified operational environment data. [0124] The AVOMC 5100 may determine or detect whether a distinct vehicle operational scenario is resolved or unresolved at 5180. For example, the AVOMC 5100 may receive operation environment information continuously or on a periodic basis, as described above. The AVOMC 5100 may evaluate the operational environment data to determine whether the distinct vehicle operational scenario has resolved.

[0125] The AVOMC 5100 may determine that the distinct vehicle operational scenario corresponding to the SSOCEM instance 5300 is unresolved at 5180, the AVOMC 5100 may send the operational environment data identified at 5170 to the SSOCEM instances 5300 as indicated at 5185, and uninstantiating the SSOCEM instance 5300 at 5180 may be omitted or differed.

[0126] The AVOMC 5100 may determine that the distinct vehicle operational scenario is resolved at 5180 and may uninstantiate at 5190 the SSOCEM instances 5300 corresponding to the distinct vehicle operational scenario determined to be resolved at 5180. For example, the AVOMC 5100 may identify a distinct set of operative conditions forming the distinct vehicle operational scenario for the autonomous vehicle at 5120, may determine that one or more of the operative conditions has expired, or has a probability of affecting the operation of the autonomous vehicle below a defined threshold at 5180, and may uninstantiate the corresponding SSOCEM instance 5300.

[0127] Although not expressly shown in FIG. 5, the AVOMC 5100 may continuously or periodically repeat identifying or updating the operational environment data at 5170, determining whether the distinct vehicle operational scenario is resolved at 5180, and, in response to determining that the distinct vehicle operational scenario is unresolved at 5180, sending the operational environment data identified at 5170 to the SSOCEM instances 5300 as indicated at 5185, until determining whether the distinct vehicle operational scenario is resolved at 5180 includes determining that the distinct vehicle operational scenario is resolved.

[0128] FIG. 6 is a flow diagram of an example of autonomous vehicle operational management with shared scenario- specific operational control management data

communication 6000 in accordance with embodiments of this disclosure. Autonomous vehicle operational management with shared scenario-specific operational control management data communication 6000 may be implemented in an autonomous vehicle, such as the vehicle 1000 shown in FIG. 1, one of the vehicles 2100/2110 shown in FIG. 2, a semi- autonomous vehicle, or any other vehicle implementing autonomous driving. For example, an autonomous vehicle may implement an autonomous vehicle operational management system, such as the autonomous vehicle operational management system 4000 shown in FIG. 4, which may include implementing autonomous vehicle management with shared scenario- specific operational control management data communication 6000 in accordance with embodiments of this disclosure. Autonomous vehicle operational management with shared scenario-specific operational control management data communication 6000 may be similar to the autonomous vehicle operational management 5000 shown in FIG. 5 except as described herein or otherwise clear from context.

[0129] As shown in FIG. 6, autonomous vehicle operational management with shared scenario-specific operational control management data communication 6000 includes an autonomous vehicle implementing or operating the autonomous vehicle operational management system 6100, including one or more modules or components thereof, which may include operating an AVOMC 6200, such as the AVOMC 4100 shown in FIG. 4 or the AVOMC 5100 shown in FIG. 5; operating operational environment monitors (not shown); and operating a SSOCEM instance 6300, such as an instance of a SSOCEM 4300 shown in FIG. 4.

[0130] The AVOMC 6200 may communicate shared scenario-specific operational control management data with an external shared scenario- specific operational control management system 6400. Communicating the shared scenario- specific operational control management data with the external shared scenario-specific operational control management system 6400 may include transmitting or sending the shared scenario- specific operational control management data, or a portion thereof, to external shared scenario-specific operational control management system 6400, receiving the shared scenario-specific operational control management data, or a portion thereof, from the external shared scenario-specific operational control management system 6400, or a combination of transmitting or sending respective portions of the shared scenario-specific operational control management data to external shared scenario- specific operational control management system 6400 and receiving respective portions of the shared scenario- specific operational control management data from the external shared scenario-specific operational control management system 6400.

[0131] An autonomous vehicle operational management system 6100 may operate in an inactive or stationary mode, such as while parked or while charging. Operating in an inactive mode may include communicating shared scenario-specific operational control management data with the external shared scenario-specific operational control management system 6400 as indicated at 6202. [0132] Communicating shared scenario-specific operational control management data with an external shared scenario-specific operational control management system 6400 in an inactive mode as indicated at 6202 may include the AVOMC 6200 receiving, from the external shared scenario- specific operational control management system 6400, shared scenario-specific operational control management data, which may include solution or policy data, experience data, or both, for one or more distinct vehicle operational scenarios. The AVOMC 6200 may receive the shared scenario- specific operational control management data as a push notification, in accordance with a systems update, in accordance with a vehicle transportation network information update, or the like.

[0133] Communicating shared scenario-specific operational control management data with an external shared scenario-specific operational control management system 6400 in an inactive mode as indicated at 6202 may include the AVOMC 6200 receiving, from the external shared scenario- specific operational control management system 6400, a request for shared scenario- specific operational control management data, which may include solution or policy data, experience data, or both, for one or more identified distinct vehicle operational scenarios. The request may include information identifying the distinct vehicle operational scenarios.

[0134] Communicating shared scenario-specific operational control management data with an external shared scenario-specific operational control management system 6400 in an inactive mode as indicated at 6202 may include the AVOMC 6200 transmitting or sending, to the external shared scenario-specific operational control management system 6400, shared scenario-specific operational control management data, which may include recently generated, such as not previously sent, solution or policy data, experience data, or both, for one or more distinct vehicle operational scenarios. The AVOMC 6200 may send the shared scenario-specific operational control management data automatically, such as periodically, in response to an event, or both. For example, the AVOMC 6200 may send shared scenario- specific operational control management data for a distinct vehicle operational scenario to the external shared scenario- specific operational control management system 6400 in response to receiving a request for shared scenario-specific operational control management data for the distinct vehicle operational scenario from the external shared scenario-specific operational control management system 6400. In another example, the AVOMC 6200 may send recently generated shared scenario- specific operational control management data to the external shared scenario- specific operational control management system 6400 while charging. [0135] An autonomous vehicle operational management system 6100 may operate in an active mode, such as in response to powering up, starting, or receiving information indicating a current destination, such as in response to user input. Operating in an active mode may include monitoring the operational environment of the autonomous vehicle at 6210, detecting distinct vehicle operational scenarios at 6220, communicate with the external shared scenario-specific operational control management system 6400 at 6230, instantiating a SSOCEM instance 6300 at 6240, traversing the vehicle transportation network at 6250, identify an operational environment of the autonomous vehicle at 6260, determining whether a distinct vehicle operational scenario is resolved at 6270, uninstantiating the SSOCEM instance 6300 at 6280, and communicate with the external shared scenario-specific operational control management system 6400 at 6290.

[0136] The AVOMC 6200 may monitor the operational environment of the autonomous vehicle, or defined aspects thereof, at 6210 to identify an operational environment, or an aspect thereof, of the autonomous vehicle. For example, operational environment monitors may monitor scenario-specific aspects of the operational environment and may send operational environment data representing the operational environment to the AVOMC 6200. Identifying the operational environment data may include identifying information indicating one or more aspects of the operational environment from route data representing an identified route for the autonomous vehicle. For example, the AVOMC 6200 may read, or otherwise receive, vehicle transportation network data representing an identified route, such as a route identified in response to user input, for the autonomous vehicle.

[0137] In another example, the AVOMC 6200 may receive information indicating a current destination, such as in response to user input, and may send information indicating the current destination to the external shared scenario-specific operational control management system 6400 as indicated at 6212. In some implementations, the AVOMC 6200 may receive information indicating a route from a current location of the autonomous vehicle to the destination from the external shared scenario-specific operational control management system 6400 as indicated at 6212.

[0138] In another example, the AVOMC 6200 may receive information indicating a current destination, such as in response to user input, the AVOMC 6200 may determine a route from a current location of the autonomous vehicle to the destination, and may send information indicating the route to the external shared scenario-specific operational control management system 6400 as indicated at 6212. [0139] The AVOMC 6200 may detect or identify one or more distinct vehicle operational scenarios at 6220. For example, the AVOMC 6200 may detect or identify one or more distinct vehicle operational scenarios at 6220 based on one or more aspects of the operational environment represented by the operational environment data identified at 6210. The AVOMC 6200 may send information indicating the distinct vehicle operational scenarios to the external shared scenario-specific operational control management system 6400 as indicated at 6222.

[0140] In another example, the AVOMC 6200 may receive information indicating the distinct vehicle operational scenarios from the external shared scenario-specific operational control management system 6400 as indicated at 6222.

[0141] Communicating the shared scenario- specific operational control management data with the external shared scenario-specific operational control management system 6400 at 6230 may include transmitting or sending the shared scenario- specific operational control management data, or a portion thereof, such as a shared scenario-specific operational control management planning data portion, to the external shared scenario-specific operational control management system 6400 at 6230.

[0142] Sending the shared scenario-specific operational control management planning data portion to the external shared scenario-specific operational control management system 6400 may include sending a shared scenario-specific operational control management planning data request to the external shared scenario- specific operational control management system 6400. The shared scenario-specific operational control management planning data request may indicate a request for shared scenario- specific operational control management planning data, such as policy data, experience data, or a combination thereof, corresponding to one or more of the distinct vehicle operational scenario identified at 6220. The autonomous vehicle operational management system 6100 may send a shared scenario-specific operational control management planning data request at other times, such as shown at 6202 or in response to receiving input, such as user input, initiating the request.

[0143] Experience, history, or episode, data may include state data, belief data, action data, observation data, or any combination thereof generated, identified, or determined in accordance with operating the autonomous vehicle. The experience data may include temporal information, such as temporal information identifying the experience data as a temporal sequence.

[0144] Communicating the shared scenario- specific operational control management data with the external shared scenario-specific operational control management system 6400 at 6230 may include transmitting or sending a shared scenario-specific operational control management operational data portion to the external shared scenario- specific operational control management system 6400, which may include solution or policy data, experience data, or both, corresponding to the distinct vehicle operational scenario. For example, the autonomous vehicle operational management system 6100 may identify a previously generated solution or policy, previously generated expectance data, or both, corresponding to the distinct vehicle operational scenario identified at 6220, and the autonomous vehicle operational management system 6100 may send a shared scenario-specific operational control management operational data portion including the previously generated data to the external shared scenario- specific operational control management system 6400 at 6230.

[0145] The shared scenario-specific operational control management operational data portion may include privacy protected data. For example, the shared scenario-specific operational control management operational data portion may include experience data, such as belief data, action data, vehicle operational scenario type data, and the like, and may omit user or vehicle identification data. In some implementations, geospatial data, temporal data, or both, may be included in the shared scenario-specific operational control management operational data portion.

[0146] Communicating the shared scenario- specific operational control management data with the external shared scenario-specific operational control management system 6400 at 6230 may include receiving the shared scenario-specific operational control management data, or a portion thereof, such as a received shared scenario-specific operational control management data portion, from the external shared scenario-specific operational control management system 6400. For example, the autonomous vehicle operational management system 6100 may receive the received shared scenario-specific operational control management data portion as a response to sending a shared scenario- specific operational control management planning data request, or the autonomous vehicle operational management system 6100 may receive the received shared scenario-specific operational control management data portion as a push notification, which may be in accordance with an autonomous vehicle systems update or a vehicle transportation network data distribution.

[0147] Communicating the shared scenario- specific operational control management data with the external shared scenario-specific operational control management system 6400 at 6230 may include receiving a received shared scenario-specific operational control management data request portion, from the external shared scenario-specific operational control management system 6400. A received shared scenario- specific operational control management data request may indicate a distinct vehicle operational scenario and a request for solution or policy data, experience data, or both, corresponding to the identified distinct vehicle operational scenario. A received shared scenario- specific operational control management data request may be received in response to transmitting or sending shared scenario-specific operational control management data to the external shared scenario- specific operational control management system 6400 at 6230. Although not expressly shown in FIG. 6, a received shared scenario- specific operational control management data request may be received by the autonomous vehicle operational management system 6100 independent of detecting the defined vehicle operational scenario at 6220.

[0148] Receiving the shared scenario-specific operational control management data from the external shared scenario-specific operational control management system 6400 may include determining whether the received shared scenario-specific operational control management data portion includes malicious data. Determining whether the received shared scenario-specific operational control management data portion includes malicious data may include determining a probability that the received shared scenario-specific operational control management data portion includes malicious data, and determining whether the probability that the received shared scenario- specific operational control management data portion includes malicious data exceeds a defined security threshold.

[0149] The received shared scenario-specific operational control management data portion may include a solution or policy for the model of the distinct vehicle operational scenario identified at 6220 and determining whether the received shared scenario-specific operational control management data portion includes malicious data may include validating the solution or policy.

[0150] Validating the solution or policy may include evaluating data indicated in the solution or policy based on relevant defined metrics. For example, the solution or policy may include utility values associated with respective belief states and validating the solution or policy may include determining whether a utility value is within a relevant defined range, such as greater than or equal to a defined minimum threshold and less than or equal to a defined maximum threshold, for the corresponding belief state. In another example, the solution or policy may include action data, such as an index or unique identifier associated with an available action, and validating the solution or policy may include determining whether the action data is valid. For example, a model may include three available actions, which may respectively have the action index values of 0, 1, and 2, action data from the solution or policy having action index values of 0, 1, or 2, may be identified as valid action data, and action data from the solution or policy having action index values other than 0, 1, or 2, may be identified as invalid. In another example, the solution or policy may include state data, such as an index or unique identifier associated with an available state, and validating the solution or policy may include determining whether the state data is valid, which may be similar to validating the action data. In another example, the solution or policy may include belief state data, such as an index or unique identifier associated with an available belief state, and validating the solution or policy may include determining whether the belief state data is valid, which may be similar to validating the action data. In another example, the solution or policy may include observation data, such as an index or unique identifier associated with an available observation, and validating the solution or policy may include determining whether the observation data is valid, which may be similar to validating the action data.

[0151] The solution or policy may include belief data and validating the solution or policy may include validating the belief data. For example, received belief data may validated by determining corresponding calculated belief data based on state transition probabilities and observation probabilities corresponding to the received belief data. Received belief data that differs from the calculated belief data may be identified as invalid or malicious data.

[0152] Validating the solution or policy may include determining whether the policy indicates an action, corresponding to a respective belief state, that has a corresponding penalty, or negative reward, that is exceeds a defined threshold. Policies that indicate actions that have penalties that exceed relevant defined thresholds may be identified as invalid or malicious data.

[0153] Validating the solution or policy may include evaluating the policy based on one more defined conditions. A defined condition may expressly identify a state, or belief state, and may indicate one or more invalid actions associated with the identified state or belief state. For example, a defined condition may indicate that state data indicates that an obstruction is blocking the path of the autonomous vehicle, and may indicate an accelerate action as an invalid action. A policy that indicates an action identified as an invalid action in a defined condition may be identified as invalid or malicious data.

[0154] Validating the solution or policy may include evaluating the policy based on one more spatial constraints. For example, a belief state indicated in a policy may correspond with a first relative spatial location for a vehicle and corresponding operative conditions, such as trajectory and velocity information for the vehicle, and a subsequent belief state indicated in the policy may correspond with a second relative spatial location for the vehicle, and evaluating the policy based on spatial constraints may include determining whether a difference between the first spatial location and the second spatial location exceeds a threshold, such as a maximum motion value, which may be determined based on the corresponding operative conditions and action.

[0155] Validating the solution or policy may include identifying differences between the solution or policy and another solution or policy. For example, the autonomous vehicle operational management system 6100 may receive a solution or policy for a POMDP model of the distinct vehicle operational scenario, the autonomous vehicle operational management system 6100 may identify a solution or policy for a MDP model of the distinct vehicle operational scenario, which may include identifying a previously generated solution or policy or generating the solution or policy, and validating the solution or policy for the POMDP model may include determining a ratio of actions (comparative ratio) from the solution or policy for the MDP model to equivalent actions from the solution or policy for the POMDP policy, wherein respective actions are correlated based on correspondence between respective states in the MDP model and collapsed belief states in the POMDP model. A solution or policy that has a comparative ratio within, such as equal to or less than, a defined threshold may be identified as a valid solution or policy and a solution or policy that has a comparative ratio that exceeds, such as is greater than, the defined threshold may be identified as an invalid policy.

[0156] Validating the solution or policy may include generating simulated experience data based on the policy and validating the experience data.

[0157] The received shared scenario-specific operational control management data portion may include scenario-specific operational control management experience data and determining whether the received shared scenario-specific operational control management data portion includes malicious data may include validating the scenario-specific operational control management experience data.

[0158] Validating the scenario-specific operational control management experience data may include temporal validation. Temporal validation may include identifying an operational state and a corresponding temporal location from the scenario-specific operational control management experience data, identifying a vehicle control action associated with transitioning from the identified operational state to a subsequent operational state from the scenario-specific operational control management experience data, identifying a temporal location associated with the subsequent operational state from the scenario-specific operational control management experience data, determining a difference between the first temporal location and the second temporal location, and determining whether the difference between the first temporal location and the second temporal location is within, a defined temporal transition range associated with transitioning from the first operational state to the subsequent operational state in accordance with the identified vehicle control action. A temporal difference that is outside the defined temporal transition range, such as less than a minimum of the defined temporal transition range or greater than a maximum of the defined temporal transition range, may be identified as indicating malicious data. A temporal difference that is within the defined temporal transition range, such greater than or equal to the minimum of the defined temporal transition range and less than or equal to the maximum of the defined temporal transition range, may be identified as indicating the omission or absence of malicious data.

[0159] In response to a determination that the received shared scenario-specific operational control management data portion includes malicious data, such as in response to a determination that the probability that the received shared scenario-specific operational control management data portion includes malicious data exceeds the defined security threshold, the AVOMC 6200 may omit using the received shared scenario-specific operational control management data portion. For example, the AVOMC 6200 may store the received shared scenario-specific operational control management data portion along with an indication that the received shared scenario-specific operational control management data portion includes malicious data, or the AVOMC 6200 may delete the received shared scenario-specific operational control management data portion.

[0160] The AVOMC 6200 may instantiate a SSOCEM instance 6300 based on one or more aspects of the operational environment represented by the operational environment data at 6240, such as in response to identifying a distinct vehicle operational scenario at 6220.

[0161] Instantiating the SSOCEM instance 6300 at 6240 may include identifying a solution or policy for a model of the distinct vehicle operational scenario identified at 6220.

[0162] Identifying the solution or policy for the model of the distinct vehicle operational scenario identified at 6220 may include determining whether the received shared scenario- specific operational control management data portion includes a solution or policy corresponding to the model of the distinct vehicle operational scenario identified at 6220. For example, in response to a determination that the probability that the received shared scenario- specific operational control management data portion includes malicious data is within the defined security threshold, identifying the solution for the scenario- specific operational control evaluation model may include determining whether the received shared scenario- specific operational control management data portion includes a solution or policy corresponding to the model of the distinct vehicle operational scenario identified at 6220. A received solution or policy may be identified as corresponding to corresponding to the model of the distinct vehicle operational scenario identified at 6220 based on a type or

categorization for the respective model. For example, the received shared scenario-specific operational control management data portion may include a solution or policy for a POMDP model of a four-way stop intersection scenario, the distinct vehicle operational scenario identified at 6220 may be a four-way stop intersection scenario, and the solution or policy included in the received shared scenario- specific operational control management data portion may be identified as corresponding to the distinct vehicle operational scenario identified at 6220. The solution or policy included in the received shared scenario-specific operational control management data portion may be a solution or policy generated based on a distinct vehicle operational scenario that geospatially, temporally, or both, from the distinct vehicle operational scenario identified at 6220. In some embodiments, other data may be used to correlate the distinct vehicle operational scenario identified at 6220 to a solution or policy indicated in the received shared scenario-specific operational control management data portion, such as geographic data, temporal data, or both.

[0163] The received shared scenario-specific operational control management data portion may include a solution or policy corresponding to the model of the distinct vehicle operational scenario identified at 6220, and instantiating the SSOCEM instance 6300 at 6240 may include identifying the solution or policy indicated in the received shared scenario- specific operational control management data portion as the solution or policy for the scenario-specific operational control evaluation model identified at 6220 and instantiating an instance of the solution or policy for the scenario- specific operational control evaluation model identified at 6220.

[0164] Identifying the solution or policy for the model of the distinct vehicle operational scenario identified at 6220 may include determining whether the received shared scenario- specific operational control management data portion includes experience data corresponding to the model of the distinct vehicle operational scenario identified at 6220. For example, in response to a determination that the probability that the received shared scenario-specific operational control management data portion includes malicious data is within the defined security threshold, identifying the solution for the scenario-specific operational control evaluation model may include determining whether the received shared scenario-specific operational control management data portion includes experience data corresponding to the model of the distinct vehicle operational scenario identified at 6220.

[0165] Instantiating the SSOCEM instance 6300 at 6240 may include generating the solution or policy for the scenario-specific operational control evaluation model identified at 6220. For example, the AVOMC 6200 may identify available resources, such as time, for generating the solution or policy for the scenario- specific operational control evaluation model identified at 6220 and the AVOMC 6200 may instantiate the SSOCEM instance 6300 at 6240 such that instantiating the SSOCEM instance 6300 at 6240 includes generating the solution or policy for the scenario-specific operational control evaluation model identified at 6220.

[0166] For example, the received shared scenario-specific operational control management data portion may include experience data corresponding to the model of the distinct vehicle operational scenario identified at 6220, and instantiating the SSOCEM instance 6300 at 6240 may include generating the solution or policy for the scenario-specific operational control evaluation model identified at 6220 using the experience data included in the received shared scenario-specific operational control management data portion, and instantiating an instance of the generated solution or policy for the scenario- specific operational control evaluation model identified at 6220. Generating the solution or policy using the experience data included in the received shared scenario-specific operational control management data portion may include determining that a previously solved, or partially solved, solution or policy is unavailable at the autonomous vehicle. Generating the solution or policy using the experience data included in the received shared scenario-specific operational control management data portion may include determining that a previously solved, or partially solved, solution or policy is available at the autonomous vehicle, and generating the solution or policy using the previously solved, or partially solved, solution or policy and the experience data included in the received shared scenario-specific operational control management data portion. Generating the solution or policy using the experience data included in the received shared scenario- specific operational control management data portion may include identifying previously generated or received experience data available at the autonomous vehicle, and generating the solution or policy using the previously generated or received experience data and the experience data included in the received shared scenario- specific operational control management data portion.

[0167] The autonomous vehicle operational management system 6100 may transmit or send, to the external shared scenario- specific operational control management system 6400, shared scenario- specific operational control management data, which may include the recently generated, such as not previously sent, solution or policy data at 6310.

[0168] In some implementations, the AVOMC 6200 may instantiate an SSOCEM instance 6300 to generate a corresponding solution or policy, such as in response to receiving a request for, or instruction to generate, the solution or policy from the external shared scenario-specific operational control management system 6400.

[0169] In some implementations, the AVOMC 6200 may suspend or uninstantiate the SSOCEM instance 6300 in response to obtaining a solution or policy for the corresponding distinct vehicle operation scenario. For example, the AVOMC 6200 may instantiate an SSOCEM instance 6300 to generate a corresponding solution or policy in response to receiving a request for, or instruction to generate, the solution or policy from the external shared scenario- specific operational control management system 6400 and may suspend or uninstantiate the SSOCEM instance 6300 in response to obtaining a solution or policy for the corresponding distinct vehicle operation scenario. In another example, the AVOMC 6200 may suspend or uninstantiate the SSOCEM instance 6300 in response to a determination that a difference between a current location of the autonomous vehicle and a location associated with the distinct vehicle operational scenario exceeds a defined threshold. The AVOMC 6200 may resume or reinstantiate the SSOCEM instance 6300 in response to a determination that a difference between a current location of the autonomous vehicle and the location associated with the distinct vehicle operational scenario is within the defined threshold.

[0170] The SSOCEM instance 6300 may generate or identify a candidate vehicle control action at 6310. The SSOCEM instance 6300 may send the candidate vehicle control action identified at 6310 to the AVOMC 6200.

[0171] The AVOMC 6200 may identify the candidate vehicle control action as a vehicle control action for traversing the vehicle transportation network and may control, or may provide the identified vehicle control action to another vehicle control unit of the autonomous vehicle to control, the autonomous vehicle to traverse the vehicle transportation network, or a portion thereof, at 6250 in accordance with the identified vehicle control action. Traverse the vehicle transportation network, or a portion thereof, at 6250 may include generating experience data, such as recent experience data, corresponding to the respective policy of the SSOCEM instance 6300.

[0172] The AVOMC 6200 may identify an operational environment, or an aspect thereof, of the autonomous vehicle at 6260. Identifying an operational environment, or an aspect thereof, of the autonomous vehicle at 6260 may be similar to identifying the operational environment of the autonomous vehicle at 6210 and may include updating previously identified operational environment data. The AVOMC 6200 may determine or detect whether a distinct vehicle operational scenario is resolved or unresolved at 6270. For example, the AVOMC 6200 may receive operation environment information continuously or on a periodic basis, as described above. The AVOMC 6200 may evaluate the operational environment data to determine whether the distinct vehicle operational scenario has resolved. The AVOMC 6200 may determine that the distinct vehicle operational scenario corresponding to the SSOCEM instance 6300 is unresolved at 6270, the AVOMC 6200 may send the operational environment data identified at 6260 to the SSOCEM instances 6300 as indicated, and uninstantiating the SSOCEM instance 6300 at 6280 may be omitted or differed. The AVOMC 6200 may determine that the distinct vehicle operational scenario is resolved at 6270 and may uninstantiate at 6280 the SSOCEM instances 6300 corresponding to the distinct vehicle operational scenario determined to be resolved at 6270.

[0173] The autonomous vehicle operational management system 6100 may, at 6290, transmit or send, to the external shared scenario-specific operational control management system 6400, shared scenario-specific operational control management data, which may include the recently generated, such as not previously sent, experience data generated at 6250.

[0177] The memory 7400 may include any tangible non-transitory computer-usable or computer-readable medium, capable of, for example, containing, storing, communicating, or transporting machine readable instructions, or any information associated therewith, for use by or in connection with the processor 7300.

[0179] The communication interface 7210 may be a wireless antenna, as shown, a wired communication port, an optical communication port, or any other wired or wireless unit capable of interfacing with a wired or wireless electronic communication medium 7800. The communication interface 7210 may be similar to the electronic communication interface 1370 shown in FIG. 1, except as indicated herein or otherwise clear from context.

[0183] FIG. 8 is a flow diagram of an example of centralized shared scenario- specific operational control management 8000 in accordance with embodiments of this disclosure. Shared scenario- specific operational control management 8000 may be implemented in a computing and communication device, such as the computing and communication device 7000 shown in FIG. 7, or the communication device 2400 shown in FIG. 2. For example, the computing and communication device implementing shared scenario-specific operational control management 8000 may be a centralized shared scenario-specific operational control management device, which may be similar to the external shared scenario-specific operational control management system 6400 shown in FIG. 6, except as described herein or otherwise clear from context. The centralized shared scenario- specific operational control management device may implement an artificial intelligence unit for shared scenario-specific operational control management.

[0184] Shared scenario-specific operational control management 8000 may include shared scenario- specific operational control management data communication with one or more external devices, such as autonomous vehicles, such as the vehicle 1000 shown in FIG. 1, one of the vehicles 2100/2110 shown in FIG. 2, which may be similar to the shared scenario-specific operational control management data communication shown at 6202, 6212, 6222, 6230, 6310, and 6290 in FIG. 6, except as described herein or otherwise clear from context.

[0185] As shown in FIG. 8, shared scenario-specific operational control management 8000 includes receiving shared scenario-specific operational control management (SSSOCM) input data at 8100, validating the shared scenario-specific operational control management input data at 8200, identifying a current distinct vehicle operational scenario at 8300, generating shared scenario-specific operational control management output data at 8400, and transmitting the shared scenario-specific operational control management output data, or a portion thereof, at 8500.

[0186] The centralized shared scenario-specific operational control management device may maintain shared scenario-specific operational control management data. For example, the centralized shared scenario-specific operational control management device may write or store the shared scenario-specific operational control management data to a data storage unit, structure, or device, such as a database of the centralized shared scenario-specific operational control management device, and may read, or otherwise access the shared scenario-specific operational control management data from the data storage unit. The shared scenario-specific operational control management data may include distinct vehicle operational scenario data, such as distinct vehicle operational scenario definition data; model data, which may be associated with corresponding distinct vehicle operational scenario data; policy data, which may be associated with corresponding model data; experience data, which may be associated with corresponding policy data; or any other shared scenario-specific operational control management data.

[0187] Shared scenario-specific operational control management input data may be received at 8100. For example, the shared scenario-specific operational control management input data may be received by the centralized shared scenario- specific operational control management device, from one or more external devices, such as autonomous vehicles, via electronic communication. Receiving the shared scenario-specific operational control management input data may include identifying the external device from which the shared scenario-specific operational control management input data is received as a current vehicle, current device, or current autonomous vehicle.

[0188] The received shared scenario-specific operational control management input data may include policy data, experience data, policy availability data, experience availability data, route data, origin data, destination data, distinct vehicle operational scenario data, vehicle configuration data, vehicle operational state data, or any other data or combination of data that may be used for shared scenario-specific operational control management.

[0189] Policy data may include a policy or solution for a distinct vehicle operational scenario. Experience, history, or episode, data may include state data, belief data, action data, observation data, or any combination thereof generated, identified, or determined in accordance with operating the autonomous vehicle. The experience data may include temporal information, such as temporal information identifying the experience data as a temporal sequence. Policy availability data may include an indication that a policy for the distinct vehicle operational scenario is available at the autonomous vehicle. Experience availability data may indicate that experience data for the distinct vehicle operational scenario is available at the autonomous vehicle. Route data may indicate a route for the autonomous vehicle to traverse the vehicle transportation network from an origin to a destination. Origin data may indicate a geospatial location in the vehicle transportation network, such as a current geospatial location of the autonomous vehicle, and may include temporal data.

Destination data may indicate a target geospatial location in the vehicle transportation network, and may include temporal data, such as a target arrival time. Distinct vehicle operational scenario data may indicate one or more distinct vehicle operational scenarios identified by the autonomous vehicle, such as distinct vehicle operational scenarios along a route. Vehicle configuration data may indicate, for example, sensor capability information for the autonomous vehicle. Vehicle operational state data may indicate a current state of the autonomous vehicle, such as a transmission state, an acceleration state, a directional control state, a power supply state, or the like.

[0190] For example, the centralized shared scenario-specific operational control management device may receive, such as periodically, in response to an event, or in response to a request from the centralized shared scenario-specific operational control management device, shared scenario-specific operational control management input data including experience data, policy data, or a combination thereof. In another example, the centralized shared scenario- specific operational control management device may receive shared scenario- specific operational control management input data indicating a request for shared scenario- specific operational control management data, such as policy data for one or more distinct vehicle operational scenarios.

[0191] The shared scenario-specific operational control management input data received at 8100 may be validated at 8200. Validating the shared scenario-specific operational control management input data may include determining whether the shared scenario-specific operational control management input data received at 8100 includes malicious data.

Determining whether the shared scenario-specific operational control management input data includes malicious data may include determining a probability that the shared scenario- specific operational control management input data includes malicious data, and determining whether the probability that the shared scenario-specific operational control management input data includes malicious data exceeds a defined security threshold.

[0192] For example, the shared scenario-specific operational control management input data may include policy data, and validating the shared scenario-specific operational control management input data may include validating the policy data. An example, of validating policy data is shown in FIG. 9. In another example, the shared scenario-specific operational control management input data may include experience data, and validating the shared scenario-specific operational control management input data may include validating the experience data. An example of validating experience data is shown in FIG. 10.

[0193] A current distinct vehicle operational scenario may be identified at 8300. The current distinct vehicle operational scenario may be identified based on the shared scenario- specific operational control management input data. For example, the shared scenario- specific operational control management input data may include a distinct vehicle operational scenario identifier indicating the current distinct vehicle operational scenario. In another example, the shared scenario-specific operational control management input data may include policy data, experience data, or both, and the current distinct vehicle operational scenario may be identified based on the policy data, experience data, or a combination thereof.

[0194] The shared scenario-specific operational control management input data may include received at 8100 may include state data, such as vehicle state data, vehicle operational environment state data, or a combination thereof, and identifying the current distinct vehicle operational scenario at 8300 may include identifying the current distinct vehicle operational scenario based on the state data, which may be similar to detecting a scenario as indicated at 5120 in FIG. 5, except as described herein or otherwise clear from context.

[0195] The shared scenario-specific operational control management input data may include origin data and destination data, and identifying the current distinct vehicle operational scenario at 8300 may include generating route data indicating a route, or multiple routes, for the source autonomous vehicle to traverse the vehicle transportation network from the origin indicated by the origin data to the destination indicated by the destination data. [0196] For example, the centralized shared scenario-specific operational control management device may determine that the shared scenario-specific operational control management input data includes an origin identifier and a destination identifier. The origin identifier may indicate an origin location, such as a geographic location, in a vehicle transportation network. The destination identifier may indicate a destination location, such as a geographic location, in the vehicle transportation network. The centralized shared scenario- specific operational control management device may determine that the shared scenario- specific operational control management input data omits a route and identifying the current distinct vehicle operational scenario at 8300 may include generating a current route for the vehicle, which may be an autonomous vehicle, to traverse the vehicle transportation network from the origin location to the destination location.

[0197] The shared scenario-specific operational control management input data may include temporal location data associated with the origin location, and generating the route may include generating the route based on the vehicle departing from the origin location in accordance with the corresponding temporal location. The shared scenario-specific operational control management input data may include temporal location data associated with the destination location, and generating the route may include generating the route such that an expected arrival of the vehicle at the destination location is in accordance with the corresponding temporal location.

[0198] The shared scenario-specific operational control management input data may include route data, or the route data may be generated based on the shared scenario-specific operational control management input data, and identifying the current distinct vehicle operational scenario at 8300 may include identifying one or more distinct vehicle operational scenarios based on the route data. For example, the centralized shared scenario- specific operational control management device may determine that the shared scenario- specific operational control management input data includes a route, and the route may be identified as the current route.

[0199] Identifying the current distinct vehicle operational scenario at 8300 may include identifying the current distinct vehicle operational scenario based on the current route. For example, the centralized shared scenario- specific operational control management device may evaluate vehicle transportation network map data to identify distinct vehicle operational scenarios along the route.

[0200] In some embodiments, the shared scenario- specific operational control management input data may include distinct vehicle operational scenario data indicating one or more distinct vehicle operational scenarios identified by the autonomous vehicle and the centralized shared scenario-specific operational control management device may evaluate vehicle transportation network map data to verify the distinct vehicle operational scenarios identified by the autonomous vehicle, which may include identifying one or more distinct vehicle operational scenarios along the route other than the distinct vehicle operational scenarios identified by the autonomous vehicle.

[0201] Although shown sequentially, validating the input data at 8200 and identifying the current distinct vehicle operational scenario at 8300 may overlap or may be combined.

[0202] Identifying the current distinct vehicle operational scenario at 8300 may include determining whether the shared scenario-specific operational control management input data indicates a policy override. For example, the shared scenario-specific operational control management input data may include an indication of a policy override for a policy for a distinct vehicle operational scenario, and the centralized shared scenario- specific operational control management device may determine that the shared scenario-specific operational control management input data may include the indication of the policy override for the policy for the distinct vehicle operational scenario.

[0203] A policy override may indicate that the source autonomous vehicle previously traversed the distinct vehicle operational scenario by performing a vehicle control action differing from a vehicle control action indicated by the distinct vehicle operational scenario indicated by the policy override. For simplicity and clarity, the distinct vehicle operational scenario indicated by the policy override may be referred to herein as a source scenario and the policy for the source scenario may be referred to herein as a source policy.

[0204] The centralized shared scenario-specific operational control management device may determine a scenario branching metric for the source scenario. For example, the centralized shared scenario-specific operational control management device may read, or otherwise access, one or more scenario branching metrics for each respective distinct vehicle operational scenario. Accessing the scenario branching metrics for a respective distinct vehicle operational scenario may include generating the scenario branching metrics for the respective distinct vehicle operational scenario based on previously identified experience data associated with the respective distinct vehicle operational scenario. The scenario branching metrics may include a cardinality of previously received policy override indications for the respective distinct vehicle operational scenario, corresponding recency information, corresponding frequency information, or the like. The centralized shared scenario-specific operational control management device may include the policy override data indicated in the shared scenario- specific operational control management input data in the scenario branching metrics for the current distinct vehicle operational scenario.

[0205] The centralized shared scenario-specific operational control management device may determine whether the scenario branching metric is within a scenario branching threshold. For example, the centralized shared scenario-specific operational control management device may determine whether the cardinality of policy overrides for the distinct vehicle operational scenario exceeds, such as greater than, a defined cardinality of policy overrides indicated by the scenario branching threshold.

[0206] The centralized shared scenario-specific operational control management device may determine that the scenario branching metric is within, such as less than or equal to, the scenario branching threshold, and may identify the source scenario as the current distinct vehicle operational scenario.

[0207] In another example, the centralized shared scenario-specific operational control management device may determine that the scenario branching metric exceeds, such as greater than, the scenario branching threshold, and may identify the current distinct vehicle operational scenario based on the source scenario.

[0208] Identifying the current distinct vehicle operational scenario based on the source scenario may include identifying branching factor, such as an aspect of the source scenario associated with the policy override or an operational condition associated with the policy override. For example, the centralized shared scenario-specific operational control management device may determine that a cardinality of policy overrides within a defined temporal period, such as a high traffic period, such as rush hour, exceeds the scenario branching threshold. In another example, the centralized shared scenario- specific operational control management device may determine that a cardinality of policy overrides for an instance of the source scenario at a defined geospatial location exceeds the scenario branching threshold. In another example, the centralized shared scenario- specific operational control management device may determine that a cardinality of policy overrides associated with a defined weather condition exceeds the scenario branching threshold. Other branching factors, or combinations of branching factors may be used. In an example, the centralized shared scenario- specific operational control management device may compare experience data associated with the policy overrides with other experience data associated with the source policy to identify state data, belief state data, or both, to identify branching factors that are similar among the policy override experience data, similar among the other experience data, and dissimilar between the policy override experience data and the other experience data.

[0209] Identifying the current distinct vehicle operational scenario based on the source scenario may include generating the current distinct vehicle operational scenario by branching, copying, or cloning the source scenario and modifying the current distinct vehicle operational scenario based on the branching factor such that a distinct vehicle operational scenario corresponding to the source scenario and omitting the branching factor is identifiable as the source scenario and a distinct vehicle operational scenario corresponding to the source scenario and including the branching factor is identifiable as the current distinct vehicle operational scenario. The centralized shared scenario-specific operational control management device may store, or otherwise maintain, the current, branched, distinct vehicle operational scenario separately from the source distinct vehicle operational scenario.

Generating the branched distinct vehicle operational scenario may include copying experience data associated with the source scenario, model data associated with the source scenario, or both. The probabilities, such as state transition probabilities, and observation probabilities, of the model of the source scenario may differ from the corresponding probabilities of the model for the branched scenario.

[0210] Shared scenario-specific operational control management output data, or a portion thereof, may be generated at 8400. Although generating shared scenario- specific operational control management output data at 8400 is shown subsequent to receiving shared scenario- specific operational control management input data at 8100 in FIG. 8, shared scenario- specific operational control management output data, or a portion thereof, may be generated at 8400 prior to receiving shared scenario-specific operational control management input data at 8100, subsequent to receiving shared scenario-specific operational control management input data at 8100, or both.

[0211] The centralized shared scenario-specific operational control management device may generate the shared scenario- specific operational control management output data, or a portion thereof, at 8400. For example, the centralized shared scenario-specific operational control management device may periodically, or in response to an event, distribute shared scenario-specific operational control management data, such as policy data, model data, experience data, or any other data that may be used for shared scenario-specific operational control management. In another example, the centralized shared scenario- specific operational control management device may respond to a request for policy data by including the requested policy data in the shared scenario- specific operational control management output data. In another example, the centralized shared scenario-specific operational control management device may include a request to generate policy data for the current distinct vehicle operational scenario in the shared scenario- specific operational control management output data.

[0212] Generating the shared scenario-specific operational control management output data at 8400 may include determining that the current policy for the current distinct vehicle operational scenario is available, and including the current policy in the shared scenario- specific operational control management output data. Generating the shared scenario-specific operational control management output data at 8400 may include determining whether current experience data for the current distinct vehicle operational scenario is available. For example, the centralized shared scenario- specific operational control management device may read, or otherwise access, an information storage unit associated with the current distinct vehicle operational scenario to determine whether the current experience data is available.

The centralized shared scenario-specific operational control management device may determine that current experience data for the current distinct vehicle operational scenario is available and may include the current experience data for the current distinct vehicle operational scenario in the shared scenario- specific operational control management output data.

[0213] Generating the shared scenario-specific operational control management output data, or a portion thereof, at 8400 may include associating the current vehicle identified at 8100 with the current distinct vehicle operational scenario identified at 8300, such as by storing, recording, or otherwise maintaining information indicating the association between the current vehicle and the current distinct vehicle operational scenario. The information indicating the association between the current vehicle and the current distinct vehicle operational scenario may include temporal information, such as information indicating a temporal validity period for the association.

[0214] Generating the shared scenario-specific operational control management output data, or a portion thereof, at 8400 may include identifying other vehicles, such as autonomous vehicles, currently associated with the current distinct vehicle operational scenario, which may include the current vehicle, such as by reading or otherwise accessing previously stored information indicating the respective associations between the other vehicles and the current distinct vehicle operational scenario, which may include determining that the association information is temporally valid, such as not expired. Identifying the autonomous vehicles associated with the current distinct vehicle operational scenario may include identifying the autonomous vehicles based on one or more grouping or clustering criteria, such as temporal proximity, spatial proximity, or a combination thereof.

[0215] For example, the centralized shared scenario-specific operational control management device may receive shared scenario- specific operational control management input data from a first autonomous vehicle indicating a route for the first autonomous vehicle. The centralized shared scenario-specific operational control management device may identify distinct vehicle operational scenarios along the route for the first autonomous vehicle. The centralized shared scenario-specific operational control management device may receive shared scenario- specific operational control management input data from a second autonomous vehicle indicating a route for the second autonomous vehicle. The route for the first autonomous vehicle may geographically overlap the route for the second autonomous vehicle, or the route for the first autonomous vehicle may be geographically disparate from the route for the second autonomous vehicle. The centralized shared scenario- specific operational control management device may identify distinct vehicle operational scenarios for the second autonomous vehicle based on the route for the second autonomous vehicle. One or more of the distinct vehicle operational scenarios identified for the first autonomous vehicle based on the route for the first autonomous vehicle may correspond with a respective distinct vehicle operational scenario from the distinct vehicle operational scenarios identified for the second autonomous vehicle based on the route for the second autonomous vehicle, and the centralized shared scenario-specific operational control management device may identify the first autonomous vehicle and the second autonomous vehicle as autonomous vehicles associated with the respective distinct vehicle operational scenario.

[0216] Generating the shared scenario-specific operational control management output data, or a portion thereof, at 8400 may include determining whether a current policy for the current distinct vehicle operational scenario is available. For example, the centralized shared scenario-specific operational control management device may read, or otherwise access, an information storage unit associated with the current distinct vehicle operational scenario to determine whether the current policy is available. Determining whether a current policy is available may include determining whether a policy for the current distinct vehicle operational scenario previously identified by the centralized shared scenario-specific operational control management device has expired or is under-optimized. For example, the centralized shared scenario-specific operational control management device may determine that a temporal location corresponding to generating the previously identified policy precedes a temporal location corresponding to received experience data for the current distinct vehicle operational scenario, and may determine that the previously identified policy has expired.

[0217] Generating the shared scenario-specific operational control management output data, or a portion thereof, at 8400 may include determining expected complexity metrics for generating the current policy. For example, the centralized shared scenario- specific operational control management device may determine that the current policy for the current distinct vehicle operational scenario is unavailable, and may determine the expected complexity metrics for generating the current policy. The expected complexity metrics may indicate an expected amount of resources, such as processor resources, temporal resources, or a combination thereof, for generating a policy for the current distinct vehicle operational scenario. The expected complexity metrics may be determined based on, for example, the type of model of the current distinct vehicle operational scenario.

[0218] Generating the shared scenario-specific operational control management output data, or a portion thereof, at 8400 may include determining whether sufficient available resources for generating the current policy are available at the current vehicle or at one or more of the other vehicles associated with the current distinct vehicle operational scenario. For example, the centralized shared scenario-specific operational control management device may identify the resources for generating the current policy based on the expected complexity metrics and may identify the resources available at a respective vehicle based on identified resource availability information. Available resources may be resources, which may include communication bandwidth, data storage resources, processing resources, temporal resources, such as a temporal distance between the respective vehicle and the current distinct vehicle operational scenario, or any other resource that may be used for generating the policy.

[0219] Although not shown separately in FIG. 8, shared scenario-specific operational control management 8000 may include generating and sending shared scenario- specific operational control management output data, or a portion thereof, indicating a request for resource availability information to one or more vehicles, such as the current vehicle and the other vehicles associated with the current distinct vehicle operational scenario, and receiving shared scenario- specific operational control management input data from one or more vehicles, such as the current vehicle or the other vehicles associated with the current distinct vehicle operational scenario, indicating current resource availability information for the respective vehicle.

[0220] Generating the shared scenario-specific operational control management output data, or a portion thereof, at 8400 may include identifying a target autonomous vehicle that has sufficient available resources, and including a request for the target autonomous vehicle to generate the current policy in the shared scenario-specific operational control management output data. For example, may include identifying the target autonomous vehicle such that resource utilization among the vehicles is uniformly distributed. In another example, the vehicle that has sufficient available resources and a minimal proximity to the current distinct vehicle operational scenario may be identified as the target autonomous vehicle.

[0221] In some embodiments, the centralized shared scenario-specific operational control management device may receive temporally overlapping routing information from multiple vehicles. The centralized shared scenario-specific operational control management device may determine commonality, such as commonality of distinct vehicle operational scenarios. The centralized shared scenario-specific operational control management device may identify respective target autonomous vehicles for generating respective policies for multiple distinct vehicle operational scenarios, and may including respective requests to generate the respective policies in the shared scenario-specific operational control management output data.

[0222] Generating the shared scenario-specific operational control management output data, or a portion thereof, at 8400 may include determining that a target autonomous vehicle that has sufficient available resources is unavailable, and the centralized shared scenario- specific operational control management device may generate the current policy. In some embodiments, the centralized shared scenario-specific operational control management device may omit identifying available resources and may generate the current policy.

[0223] Generating the current policy may be similar to the policy generation shown in FIG. 6, except as described herein or otherwise clear from context. Generating the current policy may include identifying a defined model, such as a POMDP model, of the current distinct vehicle operational scenario. For example, generating the current policy may include identifying previously received or obtained experience data for the current distinct vehicle operational scenario, such as experience data previously received from one or more autonomous vehicles, and solving the model based on the previously obtained experience data. The centralized shared scenario-specific operational control management device may identify a previously identified policy or solution for a defined model of the current distinct vehicle operational scenario, may identify subsequently generated experience data generated using the identified policy, and may generate the current policy or solution by updating the previously identified policy or solution based on the subsequently generated experience data (reinforcement or model learning). Generating the current policy may include performing function approximation, which may include identifying groupings of belief states, performing belief point compression, which may map the set of beliefs to a smaller set of beliefs.

[0224] In some embodiments, the centralized shared scenario-specific operational control management device may identify multiple external devices, such as autonomous vehicles, as a cluster, and may include a request for the cluster to generate the current policy in the shared scenario-specific operational control management output data. The request may indicate respective belief point data for respective vehicles.

[0225] The shared scenario-specific operational control management output data generated by at 8400 may include privacy protected data and may omit unprotected data.

[0226] The shared scenario-specific operational control management output data, or a portion thereof, may be transmitted at 8500. For example, the shared scenario- specific operational control management output data may be output, sent, transmitted, or otherwise communicated via a wired or wireless electronic communication medium from the centralized shared scenario-specific operational control management device to an external device, such as an autonomous vehicle.

[0227] The centralized shared scenario-specific operational control management device may generate the shared scenario- specific operational control management output data at 8400 and may transmit, send, or otherwise communicate electronically, the shared scenario- specific operational control management output data, or a portion thereof, to one or more autonomous vehicles at 8500. For example, the centralized shared scenario- specific operational control management device may include the request to generate the current policy in the shared scenario-specific operational control management output data, and transmitting the shared scenario- specific operational control management output data may include transmitting the shared scenario-specific operational control management output data, or a portion thereof, to the target vehicle identified at 8400.

[0228] In another example, the shared scenario-specific operational control management input data received at 8100 may include a request for policy data for the current distinct vehicle operational scenario from a current autonomous vehicle, the centralized shared scenario-specific operational control management device may identify available policy data for the current distinct vehicle operational scenario at 8300, the centralized shared scenario- specific operational control management device may include the policy data for the current distinct vehicle operational scenario in the shared scenario-specific operational control management output data at 8400, and the centralized shared scenario-specific operational control management device may output, transmit, send, or otherwise communicate electronically the shared scenario-specific operational control management output data, or a portion thereof, to the source autonomous vehicle at 8500.

[0229] In an example, shared scenario-specific operational control management 8000 may include an autonomous vehicle generating shared scenario-specific operational control management output data, or a portion thereof, at 8400 including experience data, previously generated by the autonomous vehicle, such as unreported data, and transmitting the shared scenario-specific operational control management output data, or a portion thereof, to the centralized shared scenario-specific operational control management device at 8500.

[0230] For example, the autonomous vehicle may generate and transmit the shared scenario-specific operational control management output data, or a portion thereof, subsequent to traversing a corresponding distinct vehicle operational scenario, or the autonomous vehicle may generate and transmit the output periodically or in response to an event, such as in an inactive or stationary mode, such as while parked or while charging. The shared scenario- specific operational control management output data, or a portion thereof, generated at 8400 and sent at 8500 by the autonomous vehicle, and received as shared scenario-specific operational control management input data by the centralized shared scenario-specific operational control management device at 8100, may include experience data respectively associated with multiple distinct vehicle operational scenarios. For example, a first portion of the experience data may be associated with a first distinct vehicle operational scenario and a second portion of the experience data may be associated with a second distinct vehicle operational scenario. Each portion of the experience data may be validated and processed as shown at 8200 and 8300, and respective processed experience data for each portion of the input experience data may be distributed as shown at 8400 and 8500.

[0231] The data sent by the autonomous vehicle at 8500 may be received by the centralized shared scenario-specific operational control management device as shared scenario-specific operational control management input data at 8100. The centralized shared scenario-specific operational control management device may validate the shared scenario- specific operational control management input data at 8200. Validating the experience data at 8200 may include identifying the distinct vehicle operational scenario corresponding to the experience data at 8300. Validating the shared scenario-specific operational control management input data may include integrating the experience data. For example, the centralized shared scenario-specific operational control management device may generate processed experience data integrating the input experience data. [0232] The centralized shared scenario-specific operational control management device may distribute the processed experience data to one or more vehicles, which may include generating shared scenario-specific operational control management output data, or a portion thereof, including the processed experience data at 8400 and transmitting the shared scenario- specific operational control management output data, or a portion thereof, to one or more vehicles at 8500.

[0233] In an example, the centralized shared scenario-specific operational control management device may receive shared scenario- specific operational control management input data at 8100 indicating a previously unidentified distinct vehicle operational scenario for a portion of the vehicle transportation network. In some embodiments, the shared scenario-specific operational control management input data may expressly indicate that the shared scenario- specific operational control management input data includes a previously unidentified distinct vehicle operational scenario for a portion of the vehicle transportation network. For example, the centralized shared scenario-specific operational control management device may receive the shared scenario-specific operational control

management input data from an external infrastructure device or system and the shared scenario-specific operational control management input data may indicate a change, which may be a permanent or temporary change, and which may be a planned or unplanned change, in the vehicle transportation network. In response to receiving the shared scenario- specific operational control management input data indicating the previously unidentified distinct vehicle operational scenario, the centralized shared scenario- specific operational control management device may validate the shared scenario- specific operational control management input data at 8200, identify the distinct vehicle operational scenario at 8300, obtain a policy for the distinct vehicle operational scenario at 8400, identify target vehicles for distributing the policy and distinct vehicle operational scenario data at 8400, and transmit the policy data, the distinct vehicle operational scenario data, or both, to the target vehicles at 8500. In some implementations, the centralized shared scenario-specific operational control management device may prioritize transmission for some vehicles, such as vehicles that have current operational conditions our routes that include, or have a probability of including that exceeds a defined threshold, the previously unidentified distinct vehicle operational scenario.

[0234] In another example, the centralized shared scenario-specific operational control management device may generate the distinct vehicle operational scenario by branching at 8300. In response to generating the distinct vehicle operational scenario by branching at 8300, the centralized shared scenario-specific operational control management device may obtain a policy for the branched distinct vehicle operational scenario at 8400, identify target vehicles for distributing the policy and distinct vehicle operational scenario data at 8400, and transmit the policy data, the branched distinct vehicle operational scenario data, or both, to the target vehicles at 8500. In some implementations, the centralized shared scenario-specific operational control management device may prioritize transmission for some vehicles, such as vehicles that have current operational conditions our routes that include, or have a probability of including that exceeds a defined threshold, the branched distinct vehicle operational scenario.

[0235] Although not shown separately in FIG. 8, a current autonomous vehicle may receive the shared scenario- specific operational control management input data from a source autonomous vehicle at 8100, the shared scenario-specific operational control management input data may include a request for a policy for a distinct vehicle operational scenario, the current autonomous vehicle may validate the shared scenario- specific operational control management input data at 8200, the current autonomous vehicle may identify the distinct vehicle operational scenario indicated in the shared scenario-specific operational control management input data as the current distinct vehicle operational scenario at 8300, the current autonomous vehicle may identify an available policy for the distinct vehicle operational scenario, the current autonomous vehicle may generate shared scenario-specific operational control management output data, or a portion thereof, including the available policy, and the current autonomous vehicle may transmit the shared scenario- specific operational control management output data, or a portion thereof, to the source autonomous vehicle at 8500.

[0236] Although not shown separately in FIG. 8, a current autonomous vehicle may identify a current distinct vehicle operational scenario, the current autonomous vehicle may identify one or more proximate autonomous vehicles, proximate to the current distinct vehicle operational scenario, the current autonomous vehicle may generate shared scenario- specific operational control management output data, or a portion thereof, including a request for a policy for the current distinct vehicle operational scenario at 8400, the current autonomous vehicle may transmit the shared scenario-specific operational control management output data, or a portion thereof, to one or more of the proximate autonomous vehicles at 8500. In response, the current autonomous vehicle may receive shared scenario- specific operational control management input data including the policy for the current distinct vehicle operational scenario from one or more of the proximate autonomous vehicles at 8100, the current autonomous vehicle may validate the shared scenario-specific operational control management input data at 8200, and the current autonomous vehicle may traverse the current distinct vehicle operational scenario using the received policy.

[0237] FIG. 9 is a flow diagram of an example of policy data validation 9000 in accordance with embodiments of this disclosure. Policy data validation 9000 may be implemented in a centralized shared scenario- specific operational control management device, such as the computing and communication device 7000 shown in FIG. 7, or the communication device 2400 shown in FIG. 2. For example, the validation shown at 8200 in FIG. 8 may include policy data validation 9000. The policy data validation 9000 shown in FIG. 9 may be similar to validating a solution or policy as shown at 6230 in FIG. 6, except as indicated herein or otherwise clear from context.

[0238] As shown in FIG. 9, policy data validation 9000 includes determining, at 9100, whether shared scenario- specific operational control management input data, such as the shared scenario- specific operational control management input data received as shown at 8100 in FIG. 8, includes policy data. For example, determining whether the shared scenario- specific operational control management input data includes policy data at 9100 may include identifying a solution or policy for a defined model of the current distinct vehicle operational scenario from the policy data from the shared scenario-specific operational control management input data.

[0239] The shared scenario-specific operational control management input data may include policy data, such as a solution or policy for a defined model of the current distinct vehicle operational scenario, the centralized shared scenario- specific operational control management device may determine that the shared scenario-specific operational control management input data includes policy data, and centralized shared scenario-specific operational control management device may validate the policy data at 9200.

[0240] Validating the policy data at 9200 may include determining whether the policy data is valid or invalid. Validating the policy data at 9200 may include evaluating data indicated in the solution or policy based on relevant defined metrics. For example, the solution or policy may include utility values associated with respective belief states and validating the solution or policy may include determining whether a utility value is within a relevant defined range, such as greater than or equal to a defined minimum threshold and less than or equal to a defined maximum threshold, for the corresponding belief state.

[0241] In another example, the solution or policy identified at 9100 may include action data, such as an index or unique identifier associated with an available action, and validating the solution or policy may include determining whether the action data is valid. For example, a model may include three available actions, which may respectively have the action index values of 0, 1, and 2, action data from the solution or policy having action index values of 0, 1, or 2, may be identified as valid action data, and action data from the solution or policy having action index values other than 0, 1, or 2, may be identified as invalid.

[0242] In another example, the solution or policy identified at 9100 may include state data, such as an index or unique identifier associated with an available state, and validating the solution or policy may include determining whether the state data is valid, which may be similar to validating the action data. In another example, the solution or policy may include belief state data, such as an index or unique identifier associated with an available belief state, and validating the solution or policy may include determining whether the belief state data is valid, which may be similar to validating the action data. In another example, the solution or policy may include observation data, such as an index or unique identifier associated with an available observation, and validating the solution or policy may include determining whether the observation data is valid, which may be similar to validating the action data.

[0243] The solution or policy identified at 9100 may include belief data (received belief data) and validating the solution or policy may include validating the belief data. For example, received belief data may validated by determining corresponding calculated belief data based on state transition probabilities and observation probabilities corresponding to the received belief data. Received belief data that differs from the calculated belief data may be identified as invalid or malicious data.

[0244] Validating, at 9200, the solution or policy identified at 9100 may include determining whether the policy indicates an action, corresponding to a respective belief state, that has a corresponding penalty, or negative reward, that is exceeds a defined threshold. Policies that indicate actions that have penalties that exceed relevant defined thresholds may be identified as invalid or malicious data.

[0245] Validating, at 9200, the solution or policy identified at 9100 may include evaluating the policy based on one more defined conditions. A defined condition may expressly identify a state, or belief state, and may indicate one or more invalid actions associated with the identified state or belief state. For example, a defined condition may indicate that state data indicates that an obstruction is blocking the path of the autonomous vehicle, and may indicate an accelerate action as an invalid action. A policy that indicates an action identified as an invalid action in a defined condition may be identified as invalid or malicious data. [0246] Validating, at 9200, the solution or policy identified at 9100 may include evaluating the policy based on one more spatial constraints. For example, a belief state indicated in a policy may correspond with a first relative spatial location for a vehicle and corresponding operative conditions, such as trajectory and velocity information for the vehicle, and a subsequent belief state indicated in the policy may correspond with a second relative spatial location for the vehicle, and evaluating the policy based on spatial constraints may include determining whether a difference between the first spatial location and the second spatial location exceeds a threshold, such as a maximum motion value, which may be determined based on the corresponding operative conditions and action.

[0247] Validating, at 9200, the solution or policy identified at 9100 may include identifying differences between the solution or policy and another solution or policy. For example, the centralized shared scenario- specific operational control management device may receive a solution or policy for a POMDP model of the distinct vehicle operational scenario, the centralized shared scenario-specific operational control management device may identify a solution or policy for a MDP model of the distinct vehicle operational scenario, which may include identifying a previously generated solution or policy or generating the solution or policy, and validating the solution or policy for the POMDP model may include determining a ratio of actions (comparative ratio) from the solution or policy for the MDP model to equivalent actions from the solution or policy for the POMDP policy, wherein respective actions are correlated based on correspondence between respective states in the MDP model and collapsed belief states in the POMDP model. A solution or policy that has a comparative ratio within, such as equal to or less than, a defined threshold may be identified as a valid solution or policy and a solution or policy that has a comparative ratio that exceeds, such as is greater than, the defined threshold may be identified as an invalid policy.

[0248] Validating the solution or policy may include generating simulated experience data based on the policy and validating the simulated experience data.

[0249] The centralized shared scenario-specific operational control management device may determine that the policy data is invalid and may ignore, delete, discard, quarantine, flag, or otherwise omit the policy data from use in shared scenario- specific operational control management.

[0250] The centralized shared scenario-specific operational control management device may determine that the policy data, or the corresponding policy, is valid, and may associate the policy with a current distinct vehicle operational scenario, such as the current distinct vehicle operational scenario identified as shown at 8300 in FIG. 8. [0251] FIG. 10 is a flow diagram of an example of experience data validation 10000 in accordance with embodiments of this disclosure. Experience data validation 10000 may be implemented in a centralized shared scenario- specific operational control management device, such as the computing and communication device 7000 shown in FIG. 7, or the communication device 2400 shown in FIG. 2. For example, the validation shown at 8200 in FIG. 8 may include experience data validation 10000. The experience data validation 10000 shown in FIG. 10 may be similar to validating scenario-specific operational control management experience data as shown at 6230 in FIG. 6, except as indicated herein or otherwise clear from context.

[0252] As shown in FIG. 10, experience data validation 10000 includes determining, at 10100, whether shared scenario- specific operational control management input data, such as the shared scenario- specific operational control management input data received as shown at 8100 in FIG. 8, includes experience data, such as current experience data associated with a current distinct vehicle operational scenario, such as the current distinct vehicle operational scenario identified as shown at 8300 in FIG. 8.

[0253] For example, the shared scenario-specific operational control management input data may include experience data associated with the current distinct vehicle operational scenario, the centralized shared scenario-specific operational control management device may determine that the shared scenario-specific operational control management input data includes experience data, the centralized shared scenario-specific operational control management device may identify the experience data as received experience data at 10100, and the centralized shared scenario-specific operational control management device may validate the experience data at 10200.

[0254] Validating the experience data at 10200 may include determining whether the experience data is valid or invalid (malicious). Validating, at 10200, the received experience data identified at 10100 may include temporal validation. Temporal validation may include identifying an operational state and a corresponding temporal location from the scenario- specific operational control management experience data, identifying a vehicle control action associated with transitioning from the identified operational state to a subsequent operational state from the scenario-specific operational control management experience data, identifying a temporal location associated with the subsequent operational state from the scenario- specific operational control management experience data, determining a difference between the first temporal location and the second temporal location, and determining whether the difference between the first temporal location and the second temporal location is within, a defined temporal transition range associated with transitioning from the first operational state to the subsequent operational state in accordance with the identified vehicle control action. A temporal difference that is outside the defined temporal transition range, such as less than a minimum of the defined temporal transition range or greater than a maximum of the defined temporal transition range, may be identified as indicating malicious data. A temporal difference that is within the defined temporal transition range, such greater than or equal to the minimum of the defined temporal transition range and less than or equal to the maximum of the defined temporal transition range, may be identified as indicating the omission or absence of malicious data.

[0255] The centralized shared scenario-specific operational control management device may determine that the experience data is invalid and may ignore, delete, discard, quarantine, flag, or otherwise omit the experience data from use in shared scenario- specific operational control management.

[0256] The centralized shared scenario-specific operational control management device may determine that the experience data is valid, and may integrate, or otherwise retain, the experience data at 10300. Integrating the experience data may include integrating the current, or received, experience data with previously integrated experience data associated with the current distinct vehicle operational scenario.

[0257] Integrating the current experience data into previously integrated experience data associated with the current distinct vehicle operational scenario may include identifying similar experience data from the previously integrated experience data based on a determined similarity to the current experience data, and generating an updated set of experience data associated with the current distinct vehicle operational scenario based on the similar experience data and the current experience data.

[0258] Generating the updated set of experience data may include pruning the experience data for the current distinct vehicle operational scenario. For example, the similar experience data for the current distinct vehicle operational scenario, including the current experience data, may have a cardinality that exceeds a defined pruning threshold, and pruning the experience data may include deleting or removing a portion of the similar experience data from the experience data associated with the current distinct vehicle operational scenario.

[0259] Although not shown separately in FIG. 8, the centralized shared scenario- specific operational control management device may periodically, or in response to an event other than receiving experience data, prune the experience data associated with one or more distinct vehicle operational scenarios. In some embodiments, pruning the experience data in response to receiving experience data may be omitted.

[0260] Generating the updated set of experience data may include merging the current experience data with the similar experience data. Merging the current experience data with the similar experience data may include determining average values, such as average probability values, for the experience data, and storing the average values.

[0261] Although not shown separately in FIG. 8, the centralized shared scenario- specific operational control management device may periodically, or in response to an event other than receiving experience data, merge the experience data associated with one or more distinct vehicle operational scenarios. In some embodiments, merging the experience data in response to receiving experience data may be omitted.
