TECHNICAL FIELD

The present disclosure relates to electrical vehicle control systems. Moreover, the present disclosure is concerned with methods of operating aforesaid electrical vehicle control systems. Furthermore, the present disclosure relates to software products stored on machine- readable data storage media and executable upon computing hardware for implementing aforesaid methods.

BACKGROUND

Conventionally, pure electrical vehicles, and also hybrid vehicles including a combination of electric motor and internal combustion engine arrangements, are well known. Generally, in comparison to simple internal combustion engine vehicles and early designs of basic electrical vehicles, modern electrical vehicles are held to require a higher standard of performance. For example, modern electrical vehicles are expected to offer a higher range of functionality than conventional vehicles. Such higher standard of performance is necessary in order to make electrical vehicles attractive for modern consumers, to encourage users to switch from using polluting internal combustion engine vehicles to cleaner electrical vehicles (assuming electrical power generation derives from clean renewable energy sources, unlikely highly polluting conventional nuclear and fossil fuel burning energy sources).

However, an ability of the modern electrical vehicles to offer more functionality usually comes at a cost of complexity of associated systems. For example, a user of the electrical vehicle may be required to exert a substantial amount of effort to learn to operate the systems associated with the electrical vehicle (such as systems responsible for charge control of the electrical vehicle, temperature control, navigation, and so forth). Furthermore, a reliability of the provided functionality may be reduced due to the user having to remember how to operate properly the various systems. Additionally, the user having to maintain multiple functionalities during operation of the electrical vehicle may lead to an unpleasant experience for the user.

Therefore, there arises a technical problem of how to implement a system for an electrical vehicle in a most effective manner that is straightforward for users to employ, and also operable to provide useful and helpful information to users and to assist in providing a pleasurable and safe driving experience.

(iv) a cabin environmental control module 138 may be configured to control a cabin temperature of the electrical vehicle.

The data communication bus of the second system layer 120 is used to exchange data between the functional modules. Specifically, the data communication bus of the second system layer 120 is operable to exchange the operational data provided with the functional modules (such as the functional modules 132 to 138). In an example, when the braking arrangement 132 is employed, operational data is being sent via the data communication bus of the second system layer 120 to the motor control arrangement 134 to restrict power to be delivered to an electrical motor propelling the electrical vehicle when in operation.

The data communication bus of the second system layer 120 is operable to provide data to the first system layer 110 for the software application management and infotainment arrangement 114 to perform data analysis, strategic control and reporting to a user of the electrical vehicle. Specifically, the data communication bus of the second system layer 120 is operable to provide operational data from the functional modules (such as the functional modules 132 to 138) of the third modular layer 130 to the software application management and infotainment arrangement 114 of the first system layer 110.

Furthermore, in such example the software application management and infotainment arrangement 114 may also report the user about any potential destination (such as a charging station) in the route to the destination ABC.

In an embodiment, the second system layer 120 is operable to couple user control signals directly from the user to the third modular layer 130, when the control signals relate to safety critical functions during driving of the electrical vehicle. The term 'control signal' used herein relates to the vehicle operational function provided by the user of the electronic vehicle for controlling a function of the vehicle. In an example, the user operation signal such as the application of brakes to stop movement of the vehicle will be directly sent to the braking arrangement 132 of the third modular layer 130.

In an embodiment, the driving characteristics may include but not limited to a selection of automatic or manual drive-train manners of operation; acceleration characteristics of the motor controller when providing power in operation to an electrical motor of the electrical vehicle; demand response functionality provided by the electrical vehicle when connected to a power grid 242; a manner of electrical power transfer between the battery unit 220 and the electrical motor 230 when the electrical vehicle is driven in operation; and an economy of power utilization within the electrical vehicle in respect of cabin heating and battery unit 220 discharge.

In an exemplary embodiment, an operating parameter may be a binary selection of manual or automatic transmission as a stored binary digit parameter in the second system layer. Another example could be selection of a "sport mode" or "economy" mode of driving as a stored parameter in the second system layer.

In another exemplary embodiment, a responsive operating parameter may be a temperature dependent parameter that is supplied information from a sensor communicating with the first system layer, such parameter stored on the second system layer, but controlled from the first system layer, to influence communicated data between functional modules in the third system layer.

In an embodiment, the first system layer 110 may be operable to control operating parameters received from the second system layer 120, for controlling driving characteristics of the electrical vehicle. As aforementioned, the data communication bus of the second system layer 120 is operable to exchange the operational data provided with the functional modules, for example operational data is sent from the braking arrangement to the motor control arrangement. In an event of purely direct communication, the response may be on the basis of a predefined program. However, it is advantageous if the user or other functions in the car that can sense a changed situation can control such a communication by providing the second system layer with parameters to influence the response without having to revert to the first system layer. In an embodiment, the software application management and infotainment arrangement (SAMI) 114 may use the sensor signal parameters received from the sensor arrangement 140 based on changes in conditions outside the cabin of the electrical vehicle via the second system layer 120, and may recommend the driving characteristics to the user of the electrical vehicle based on the measured conditions outside the cabin of the electrical vehicle. This embodiment is advantageous in terms of efficient and optimal use of battery unit 220.

In an embodiment, the conditions outside the cabin of the electrical vehicle may include but not limited to environmental conditions, road conditions, traffic conditions, and visibility.

The term 'fault conditions' used herein relate to the malfunctioning of the functional elements of the electrical vehicle, such as data communication bus, brakes, electrical motor, clutch and gearbox, battery unit, and so forth. In an embodiment, the functional elements of the electrical vehicle may be coupled with a sensory arrangement, that are operable to provide the data related to the operation of the functional elements to the first system layer 110 for monitoring. Furthermore, in such embodiment, the data related to the operation of the functional element may be provided to the software application management and infotainment arrangement 114 of the first system layer 110 for analysis. In an example, the motor control arrangement 134 of the third modular layer 130 may be coupled with a sensory arrangement, that is operable to provide operational data to the software application management and infotainment arrangement 114 of the first system layer 110. In such example, the operational data related to the motor control arrangement 134 may be related to the time required to slow down the electrical motor propelling the electrical vehicle when in operation. Furthermore, in such an example, every time the electrical motor slows down, the time required is stored in the data memory of the software application management and infotainment arrangement 114. Therefore, in the event when the time required by the electrical motor to slow down is more than a predefined threshold value, the software application management and infotainment arrangement 114 may identify the event as a fault condition. Optionally, the software application management and infotainment arrangement 114 may notify the user of the electrical vehicle via the graphical user interface (GUI) 112 about the fault condition related to the motor control arrangement 134 of the electrical vehicle.

In an embodiment, the first system layer 110 is operable to organize rescue, maintenance and servicing schedules for the electrical vehicle, based upon sensor data received from the second system layer 120 and/or from the third system layer 130. Specifically, the rescue, maintenance and servicing schedules for the electrical vehicle may be related to an appointment made for the electrical vehicle, with service providers providing the services of rescue, maintenance and servicing for electrical vehicles. In an example, the software application management and infotainment arrangement 114 may be operable to contact an electrical vehicle repairing service provider for providing maintenance to the electrical vehicle, in the event of the detecting a fault condition in the electrical vehicle, or an onset of a fault condition likely to occur in future. In another example, the software application management and infotainment arrangement 114 may be operable to automatically book/ reserve a time slot for the charging of the electrical vehicle at a nearest charging station, in the event when the software application management and infotainment arrangement 114 detects a lesser amount of charge in the electrical vehicle. In yet another example, the software application management and infotainment arrangement 114 of the electrical vehicle may be operable to send a rescue signal (such as SOS) to the service provide providing the rescue service to electrical vehicles in the event of an accident or breakdown of the electrical vehicle.

In an embodiment, the first system layer 110 is operable to organize a vehicle driving route for the electrical vehicle in response to user instructions and a state of charge of the battery unit of the electrical vehicle. For example, the software application management and infotainment arrangement 114 of the electrical vehicle may be operable to derive a route to a destination selected by a user of the electrical vehicle. In such example, the software application management and infotainment arrangement 114 may be operable to provide the user with a navigation application such as SATNAV, wherein the user may select a destination for travelling thereto. Furthermore, in such an example, the software application management and infotainment arrangement 114 may be operable to detect the amount of charge required by the electrical vehicle for travelling to the destination. Additionally, the software application management and infotainment arrangement 114 may suggest the user of the electrical vehicle to charge the battery of the electrical vehicle before travelling and/or suggest the user to charge the electrical vehicle after travelling a certain distance (using a nearest charging station). Optionally, the software application management and infotainment arrangement 114 may be operable to suggest the user of the electrical vehicle to drive with a specific speed or in a specific mode of travelling (such as an "economy mode") .

Referring to FIG. 2, there is illustrated a block diagram of components of the electrical vehicle control system 100 of FIG. 1, in accordance with an embodiment of the present disclosure. As shown, the electrical vehicle control system 100 comprises the software application management and infotainment arrangement 114 that may acquire input from a user 210 of the electrical vehicle via the graphical user interface (GUI) 112. Optionally, the software application management and infotainment arrangement 114 included in the first system layer is operable to control operating parameters of the second system layer, for controlling driving characteristics of the electrical vehicle. Optionally, such input by the user 210 may include a selection of automatic or manual drive-train manners of operation. For example, the user 210 may make the selection of automatic drive- train manner of operation that may include "drive", "reverse" and "park" modes of control of the electrical vehicle. In another example, the user 210 may make the selection of manual drive-train manner of operation that may enable the user to make one of four gear choices (and optionally one or more reverse gears) related to different driving speeds of the electrical vehicle.

Specifically, the first system layer 110 is operable to control operating parameters that is to be communicated by the second system layer 120, for controlling driving characteristics of the electrical vehicle. More specifically, the software application management and infotainment arrangement (SAMI) 114 hosted by the first system layer 110 is operable to control operating parameters that is to be communicated by the second system layer 120. Furthermore, the operating parameter that is to be communicated by the second system layer 120 refers to the data in the operational data that defines the terms of communicating the information to and/or from the functional modules of the electric vehicle. In an example, the operating parameter that is to be communicated may include terms of segmenting the information electric vehicle (namely the information of the functional modules). In another example, the operating parameter that is to be communicated may include selectively transferring the segmented data. In another example, the operating parameter that is to be communicated may include instruction to manipulate the operational data. In yet another example, the operating parameter that is to be communicated may include a time period upon which the data is to be communicated.

Furthermore, the electrical vehicle control system 100 is communicably coupled to the third modular layer (such as the third modular layer 130 of FIG. 1) comprising the battery management system 136 of the electrical vehicle for controlling discharging and charging of a battery unit 220 of the electrical vehicle, wherein the battery unit 220 is operable to provide operating power to the electrical vehicle. As shown, the battery unit 220 is communicably coupled to the motor control arrangement 134 of the electrical vehicle for controlling power delivered to an electrical motor 230 for propelling the electrical vehicle when in operation. Optionally, the software application management and infotainment arrangement 114 may be operable to control a manner of electrical power transfer between the battery unit 220 and the electrical motor 230 when the electrical vehicle is driven in operation. For example, when the user 210 of the electrical vehicle depresses an accelerator pedal (not shown) of the electrical vehicle, a signal indicative of mechanical movement of the accelerator pedal is sent to the software application management and infotainment arrangement 114. In such instance, the software application management and infotainment arrangement 114 is operable to provide electrical power from the battery unit 220 to the electrical motor 230 to accelerate the electrical vehicle. Optionally, the software application management and infotainment arrangement 114 is operable to control acceleration characteristics of the motor controller when providing power in operation to an electrical motor of the electrical vehicle. For example, in an "economy mode" of operation of the electrical vehicle, the software application management and infotainment arrangement 114 may be operable to provide less power to the electrical motor 230 in response to user depression of the acceleration, when compared to a "sport mode" of operation when the software application management and infotainment arrangement 114 is operable to provide relatively more power to the electrical motor 230 to control acceleration of the electrical vehicle.

Additionally, the motor control arrangement 134 is communicably coupled to a clutch arrangement, a gearbox arrangement and a differential gear arrangement, indicated generally by 232, that is operable to control an output torque provided to wheels of the electrical vehicle. Moreover, the clutch arrangement, the gearbox arrangement and the differential gear arrangement 232 are operable to be controlled by the user 210 of the vehicle, for example, using a clutch-pedal, a gear-change lever and a steering arrangement (not shown) of the electrical vehicle.

Furthermore, the software application management and infotainment arrangement 114 is communicably coupled to the cabin environmental control module 138 of the electrical vehicle, for controlling a cabin temperature of the electrical vehicle. For example, the cabin environmental control module 138 may be operable to provide heating in a cabin of the vehicle based on a temperature of the cabin of the vehicle. Optionally, the software application management and infotainment arrangement 114 may be operable to control an economy of power utilization within the electrical vehicle in respect of cabin heating and battery unit charge depletion. For example, the software application management and infotainment arrangement 114 may be operable to determine an amount of charge remaining in the battery unit 220. In such an instance, response to determination of an insufficient charge in the battery unit 220, the software application management and infotainment arrangement 114 may be operable to utilize waste heat from the battery unit 220 to provide heating in the cabin of the electrical vehicle.

Additionally, as shown the software application management and infotainment arrangement 114 is communicably coupled to a power switching unit 240 that is further coupled to a power grid 242. The software application management and infotainment arrangement 114 is operable to communicate to the power switching unit 240 to allow, for example, power to be drawn from the power grid 242 to be provided to the battery unit 220 and a home of the user, or to allow power to be drawn from the battery unit 220 to provide power to the home of the user. Optionally, the software application management and infotainment arrangement 114 may be operable to control demand response functionality provided by the electrical vehicle when connected to a power grid 242. For example, the software application management and infotainment arrangement 114 may be operable to receive information indicative of the power grid 242 experiencing a high power demand (or becoming overloaded in operation) and, in response to such a condition, the software application management and infotainment arrangement 114 may be operable to instruct the power switching unit 240 to draw power from the electrical vehicle to provide demand response to the power grid 242.

Moreover, as shown, the software application management and infotainment arrangement 114 is coupled to a GPS module 250 that may enable a geographical location of the electrical vehicle to be determined.

Furthermore, the method of operating the electrical vehicle control system for an electrical vehicle is implemented on a software product recording on machine-readable data storage media, characterized in that the software product is executable upon computing hardware

The electrical vehicle control system of the present disclosure allows user control signals to be coupled directly from the user to the third modular layer. Such a configuration allows the user to maintain control of safety critical functions (such as braking), in an event of a software glitch causing the software application management and infotainment arrangement to stop execution (namely, "hang up"). Furthermore, the software application management and infotainment arrangement included in the first system layer is operable to monitor for fault conditions developing in the second and third system layers. Such monitoring may allow a potential malfunction of a component of the second or third system layers to be identified before malfunctioning thereof and allow an appropriate action to be taken in response thereto, for example performing a maintenance operation on the vehicle. The software application management and infotainment arrangement included in the first system layer, that is operable to organize a vehicle driving route based upon a state of charge of the battery unit of the electrical vehicle, may reduce a chance of breakdown due to lack of charge in the battery unit of the electrical vehicle while travelling. Additionally, software application management and infotainment arrangement, that is operable to organise a vehicle information log to be sent to a user on a user device, allows the user to monitor remotely the electrical vehicle (such as to track the electrical vehicle in an event of theft thereof).
