FIELD OF THE INVENTION

The present invention relates to a method for retrieving data, such as telematics data, from a vehicle, to which a tour is assigned, and forwarding at most a subset of those data to an observer.

BACKGROUND OF THE INVENTION

The present invention relates to a monitoring of the vehicle position, logistics and data handling systems.

Monitoring of vehicles is an important aspect in logistics management and surveillance. Various methods and different data collection systems are used to collect data associated with monitoring of vehicles. The collected data can be transmitted to a central monitoring system, which monitors a vehicle, based on the reported data. The monitoring of the vehicles and the associated data transmission is achieved by use of data transmission systems. The data is retrieved by the central monitoring system and forwarded to third parties.

Collection of logistic data is an essential factor for companies to better manage the large amount of data coming from many different systems belonging to different data owners. Retrieving, processing and forwarding of data is executed via. geofence-based triggers.

By using geofence based triggers for data distribution to third parties (in the following referred to as "observers") can be turned off and on at desirable times. Geofences is established via factors such as: pick-up location, delivery location and time windows (scheduled pickup and delivery).

The advantages and disadvantages of using large and/or small geofences is a recurring problem.

OBJECT OF THE INVENTION

An object of the present invention is to provide an alternative to the prior art.

It is in particular an object of the present invention to provide a method for retrieving data, such as telematics data, from a vehicle, to which a tour is assigned, and forwarding at least a subset of those data to an observer. The tour definition being the data distribution contract between the sovereign data owner and the observer. SUMMARY OF THE INVENTION

DETAILED DESCRIPTION OF AN EMBODIMENT

Reference is made to figure 1 schematically illustrating a data flow according to a first embodiment of the present invention.

The invention as disclosed herein utilizes determination of location, which typically is carried out by a gps (global positioning system), preferably positioned in the vehicle for which a location is to be determined. Further, passing a geofence e.g. entering or exiting a geofence is typically determined by comparing the gps position of the vehicle and comparing this with the location of the geofence; e.g. entering a geofence is said to occur when the gps location of the vehicle is inside the geofence, similarly, exit of the geofence is said to occur when the gps location of the vehicle is outside the geofence.

In the first embodiment, the present invention relates to a method for retrieving data 20, such as telematics data, from a vehicle 1, to which a tour is assigned, and forwarding at least a subset 21 of those data to an observer. No data is retrieved when no tour is assigned to said vehicle. The method comprises the steps of:

- determining a location 5, 6, 7, 8, 9, 10 of the vehicle 1,

providing two concentric geofences 2, the concentric geofences 2 comprises an outer geofence 3 and an inner geofence 4,

- define a start concentric geofence 11 with a pick-up location inside an inner geofence and an end geofence 12 with a delivery location inside an inner geofence;

- after a tour is assigned to said vehicle, retrieve at a server the data 20 from the vehicle 1,

- forwarding from the server a subset 21 of the data to the observer, where the subset 21 is defined as data retrieved from the vehicle being within a geographical region defined as where the vehicle enters an outer 3 geofence of the start concentric geofence 11 and exit of an inner geofence of an end concentric geofence 12.

It is noted, that the geofences typically is set-up before e.g. location

determination is performed. Further, while preferred embodiments of the invention comprises retrieving data from the vehicle after a tour is assigned, other embodiments may include data retrieval during other timeframes, such as during a timeframe including time before a tour is assigned and/or after the tour is completed.

Figure 1 schematically illustrates a vehicle 1 driving along a path, with different locations 5, 6, 7, 8, 9 or 10. Two concentric geofences 2 are provided : a start concentric geofence 11 and an end geofence 12. The start concentric geofence 11 defines a pick-up location inside an inner geofence and an end geofence 12 with a delivery location inside an inner geofence.

When the vehicle has no tour assigned, (corresponding to location 5 on figure 1) no data is retrieved at the server. After a tour is assigned (location 6 in figure 1). to the vehicle, data 20 is retrieved at a server from the vehicle 1.

When the vehicle is within a geographical region defined as where the vehicle enters an outer 3 geofence of the start concentric geofence 11 and exit of an inner geofence of an end concentric geofence 12, a subset of data 21 is forwarded to the observer, where the subset 21 of data is defined as data retrieved from the vehicle.

In the illustrative example in figure 1, when the vehicle has made its pickup (location 9 In figure 1) in the inner geofence 4 of the start concentric geofence 11 it then exit the outer geofence 3 of the start concentric geofence 11 and drives towards the end concentric geofence 12. In another embodiment, (not illustrated in figure 1) additional pickups (intermediate concentric geofences, such

intermediate concentric geofence 13 of fig. 3) may be arranged between start concentric 11 and the end 12 concentric geofence, said additional geofences may be seen as intermediate pickups and/or drop offs between start concentric geofence 11 and end concentric geofence 12.

When the vehicle has exit an inner geofence 4 of the end 12 concentric geofence, no subset 21 of the data is forwarded to the observer.

When the vehicle has completed the tour (location 8 figure 1) no data 20 is retrieved to the server from the vehicle 1.

In another embodiment, the method may further comprise the step of processing the subset 21 of data, when the vehicle being within a geographical region defined as where the vehicle enters an outer 3 geofence of the start concentric geofence 11 and exit of an inner geofence of an end concentric geofence 12.

In yet another embedment, the method may further comprise the step of determining whether the vehicle has entered and exited the inner geofence 4 of the start concentric geofence 11 and whether the vehicle has entered and exited the inner geofence 4 of the end concentric geofences 12, and in confirmative case assign the tour to be completed.

The data 20 may be in the form of telematics data; the telematics data being retrieved via one or more data retrieving devices arranged on the vehicle 1.

In another embodiment of the present invention, the tour may be initiated by the vehicle entering any one of the outer geofence of the concentric geofences 2 defined by the method. It is not necessarily the "closest" concentric geofence to the vehicle, which may trigger the tour to be initiated and start forward a subset 21 of the data to the observer. The first outer geofence of the concentric geofence 2 which the vehicle enters in the time frame, initiates a forward of the subset of data. The tour may comprise multiple stops (intermediate concentric geofences). The tour may be completed when the vehicle enters and exit all of the outer geofences of all the concentric geofences 2 in the tour.

A subset 21 of data is forwarded to the observer when the vehicle has entered the outer geofence of a concentric geofence.

When the vehicle has exit the inner geofence of the end concentric geofence stop forwarding of a subset of data to the observer.

The method may further comprise a time frame, which ensures that a subset of the retrieved data only can be forwarded to the observer during this timeframe. In another aspect, the timeframe may also be used to limit or completely reject the possibility of retrieving data from the vehicle. The time frame may also be used to ensure that the vehicle completes the tour within the time frame.

If the stop of forwarding of data is initiated on the basis of a time frame, it is because the method have not registered if the tour is completed or not within the limits of that time frame.

Reference is now made to figure 2, schematically illustrating retrieving and forwarding of as subset of data according to an embodiment of the present invention.

In a preferred embodiment of the present invention, the concentric geofences, comprises an inner geofence having a radius smaller than the outer geofence.

In another embodiment of the present invention, the outer geofence 3 has a radius from 0-100 km, such as 0-50 km, preferably 0-25 km.

The inner geofence 4 may have a radius from 0-20 km, such as 0-10 km, preferably 0-1 km. In another embodiment (not shown in the figures), a shape of the geofences is selected from the group comprising : circle, polygon, such as polygenic.

The method may further comprise the step of determining whether said inner geofence 4 of the start concentric geofence 11 and the outer geofence 3 of the end concentric geofence 12 overlap, and in confirmative case initiate a dynamic adaption of the shape of the start concentric geofence 11 and/or the end concentric geofence 12. This example is schematically illustrated in figure 7. a schematically illustrating an example where initially set geofences overlap. As illustrated in fig. 7. a the outer end geofence 12 overlaps the start concentric geofences (both inner 11 and outer 12 geofences) and vice versa.

The method may further comprise the step of determining whether said inner geofence 4 of the start concentric geofence 11 and the inner geofence 4 of the end concentric geofence 12 overlap, and in confirmative case initiate a dynamic adaption of the shape of the start concentric geofence 11 and/or the end concentric geofence 12. This example is schematically illustrated in figure 7.b

The method may further comprise the step of determining whether the outer geofence 3 of the start concentric geofence 11 and the outer geofence 3 of the end concentric geofence 12 overlap, and in confirmative case initiate a dynamic adaption of the shape of the start concentric geofence 11 and/or the end concentric geofence 12. This example is schematically illustrated in figure 7.c. As an alternative to the adaptation shown in fig. 7.c, the adaption shown in fig. 7.b may be application to the situation illustrated in fig. 7.c

The method may further comprise the step of determining whether the outer geofence 3 of the start concentric geofence 11 and the inner geofence 4 of the end concentric geofence 12 overlap, and in confirmative case initiate a dynamic adaption of the shape of the start concentric geofence 11 and/or the end concentric geofence 12. This example is schematically illustrated in figure 7.d.

As illustrated in fig. 7, the dynamic adaption typically involves reducing the areas spanned by the geofences in question to a size where no overlap exist or (as shown in fig. 7.b) where the geofences has a common section (the vertical line in the lower part of fig. 7.b) shared by the two geofences. During the dynamic adaptation, it should be assured that the inner geofences are not changed so as to not covering a pick-up and delivery position. If possible, it may be preferred to perform a dynamic adaption only on the outer geofences.

Referring to fig. 8, the boundary 24 of one or more of the geofences, may in another embodiment, conform to course of roads within said tour, as

schematically illustrated in figure 8. Such course or roads may e.g. be one or more roads encircling a part of a city.

In some instances, a vehicle travels through the geofences on a daily basis and delivers goods for different clients on different days. In order to assure that the data is transmitted correctly on the correct day as an example, the method may further comprise the step of determining whether entering and exiting geofences occurs during a predetermined period in time (or as referenced above: within a timeframe) and only forwarding subset of data if this occurrence is present during the predetermined period in time. Such a predetermined period of time may e.g. be a time period on a weekday (say Monday between 1 pm and 4 pm) and by applying such a further criteria for transmitting data, it may thereby be assured that data is not transmitted in case the vehicle travels passes the geofences on subsequent Tuesday (as an example).

In some embodiment it may also be preferred to collect and transmit information as to a vehicle approaching a delivery (or pick-up) position and as to whether the vehicle has arrived at the delivery (or pick-up) position. To this, sub-geofences are assigned inside the inner geofence as illustrated in fig. 9. In the illustrative example in figure 9, the inner geofence 4 of the end concentric geofence 12 may comprise a sub-geofence 22, 23 including the delivery location, defining an approaching region and an arriving region, the method further comprising generating :

a signal indicating that a vehicle is approaching when the vehicle enters the approaching region 22;

a signal indicating that a vehicle has arrived when the vehicle enters the arrival region 23; a signal indicating that the vehicle has departed when the vehicle leaves the arrival region.

A signal is to be understood in broad terms including data containing information on that the event has occurred. It is noted that it is also within the scope of the invention to apply only one of either approaching region or arrival region. Such a signal is typical transmitted in the same manner as other data disclosed herein.

In another embodiment of the present invention, the retrieving of data is executed maximum 24 hours before the vehicle has entered the inner geofence 4 of the start concentric geofence 11 and maximum 12 hours after the vehicle has exited 10 inner geofence 4 of the end concentric 12 geofence.

Forwarding of the subset 21 of data may be executed maximum two hours before a tour is assigned 6 to the vehicle 1 and maximum 12 hours after the vehicle has exited 10 inner geofence 4 of the end concentric 12 geofence.

The link between the time frame and concentric geofences is to ensure that the vehicle enters and/or exit the concentric geofences 2 within the time frame; so to ensure that the right vehicle is in the right location at the right time.

Reference is now made to figure 3, schematically illustrating retrieving and forwarding of as subset of data according to an embodiment of the present invention.

In figure 3, the "classic Tour" illustrates a "perfect" pickup and deliver route for a vehicle which a tour is assigned to. In the illustrative example of figure 3 "Classic tour" the tour is defined by three concentric geofences. When the vehicle is assigned as tour, a subset of data is retrieved from the vehicle to a server, during the time frame of the tour.

When the vehicle enters the outer geofence of the first concentric geofence, a subset of the data is forward to an observer. The subset of data is forwarded to the observer as the vehicle is on the path to the intermediate concentric geofence 13 on fig 3 "Classic tour" and until the vehicle has exited the outer geofence of the end concentric geofence 12. Data is retrieved by the server as long as a tour is assigned to the vehicle, being within the time frame of the tour. When the tour is competed, no data is retrieved by the server and no data is forwarded to the Observer.

In another embodiment, the method further comprises the step of determining whether the vehicle has entered and exited the inner geofence 4 of the end concentric geofences 2, and in confirmative case assign the tour to be completed. In figure 3 "imprecise stop" is illustrated the step of determining whether the vehicle has entered and exited the outer geofence 3 of the start concentric geofence 11 and whether the vehicle has entered an exited an outer geofence of the intermediate concentric geofence 13 and whether the vehicle has entered and exited the inner geofence 4 of the end concentric geofences 12, and in

confirmative case assign the tour to be completed.

The "imprecise stop" tour is characterized in that if the vehicle enters and exit only the outer geofence of the intermediate concentric geofence 13, it is registered as the pickup or delivering is completed. Figure 3 "imprecise last stop" illustrates the step of determining whether the vehicle has entered and exited the inner geofence 4 of the start concentric geofence 11 and whether the vehicle has entered and exited an inner geofence of the intermediate concentric geofence 13 and whether the vehicle has entered and exited only the outer geofence of the end concentric geofences 12, and in confirmative case assign the tour to be completed.

Reference is now made to figure 4, schematically illustrating retrieving and forwarding of a subset of data according to an embodiment of the present invention.

Figure 4 "missing a stop" illustrates the step of determining whether the vehicle has not entered and exited the outer geofence of an intermediate concentric geofence 13 and in confirmative case not assign the tour to be completed.

The tour is completed within a timeframe. Figure 4 "missing last stop" illustrates the step of determining whether the vehicle has not entered and exited the outer geofence 3 of the end concentric geofence 12 and in confirmative case not assign the tour to be completed. The tour is completed within a timeframe.

Figure 4 "missing first pickup" illustrates the step of determining whether the vehicle has not entered and exited the outer geofence 3 of the start concentric geofence 11 and in confirmative case change size of the end concentric geofence 12 and/or the start concentric geofence 11. The tour is completed within a timeframe.

Reference is now made to figure 5, schematically illustrating retrieving and forwarding of as subset of data according to an embodiment of the present invention.

Figure 5 "one stop tour" illustrates the step of determining whether the vehicle has entered and exited a single concentric geofence 2. A subset 21 of data is forwarded to the observer from entering the concentric geofence until exiting the same concentric geofence.

Figure 5 "MISSING ALL" illustrates the step of determining whether the vehicle has not entered the outer geofence of the start concentric geofence 11 and not entered the outer geofence of the intermediate concentric geofence 13 and not entered the outer geofence of the end 12 concentric geofence. In confirmative case not forward subset 21 of data to the observer.

Figure 6 is a schematically view of the flow diagram of the method according to an embodiment of the present invention.

The row "initiate" corresponds to "initiate" on figure 1, schematically illustrating the sequence when the vehicle receives the tour and start retrieving data from the vehicle to a server.

When the vehicle enters the outer geofence of the start concentric geofence 11, the sequence "Begin" is initiated. The method initiates the step of forwarding a subset of the data to an observer, as long as the vehicle is between the outer geofence of the start concentric geofence and until it exits an inner geofence of the end concentric geofence.

When the vehicle has exit the inner geofence of the end concentric geofence, data is retrieved but no subset of data is forwarded to the observer. When the vehicle has completed the tour (position 8 in figure 1) no data is retrieved to the server.

In preferred embodiments, the vehicle has a gps and a transmitter for

transmitting gps data to a central server. These data may be tagged with a identifier to uniquely identify a vehicle. This central server is configured by a software implementation to execute the various steps according to the present invention. Accordingly, the central server keeps track of the position of the vehicle and whether the vehicle has entered or exited the geofences as disclosed herein, and if the criteria for transmitting data to the observer is satisfied, the central server transmits data to the third party.
