Description

[0001] Procedure, system and vehicle

[0002] The present invention relates to a method for suggesting charging stops along a route for a battery-electric vehicle. The invention also relates to a system for implementing the method and a battery-electric vehicle that can be used in the system for implementing the method.

[0003] Vehicles can be equipped with a navigation system to determine a route to a destination. For vehicles with combustion engines, the vehicle's range plays a minor role, as refueling stations are widespread and can be found almost everywhere. In contrast, for battery-electric vehicles, longer journeys may require at least one charging stop along the route, as the number of available charging stations is still small compared to the number of refueling stations.

[0004] From DE 102022 119 014 A1 a system and a method for suggesting a charging station along a route are known, in which a charging point suitable for a charging stop is determined depending on the current range of the vehicle or the current charge state of the vehicle battery and is displayed in a display of a navigation device in addition to the route.

[0005] From DE 102020 110 588 A1, it is known to take into account the range of a battery-electric vehicle or the current charge level of a vehicle battery when calculating a route in order to provide at least one charging stop along the route, so that the route leads the vehicle via the respective charging stop to the desired destination. In this known method, two different routes are first determined, with one route containing a larger number of shorter charging stops, while the other route contains a smaller number of longer charging stops. By comparing the two routes, the one that promises the shortest overall travel time is then selected.

[0006] Scheduling charging stops is unpopular with drivers (male / female / diverse), as a charging stop typically takes significantly longer than a refueling stop. Drivers feel like their time is being wasted and unused, which is detrimental to the acceptance of battery-electric vehicles.

[0007] The present invention addresses the problem of improving the quality of charging stops for drivers of battery-electric vehicles in order to increase the acceptance of battery-electric vehicles.

[0008] This problem is solved according to the invention by the subject matter of the independent claims. Advantageous embodiments are the subject matter of the dependent claims.

[0009] The invention is based on the general idea of ​​synchronizing the routes of at least two vehicles with regard to a charging stop, so that two or more vehicles can meet at a predetermined charging station for a joint charging stop. Care is taken to ensure that the associated drivers have common interests. This enables an exchange of interests between the drivers during the joint charging stop, making the charging stop more entertaining. This largely compensates for the aforementioned disadvantages of time-consuming charging stops.

[0010] In order to bring together drivers with the same or similar interests at such a shared charging stop, driver data and / or vehicle data from a large number of battery-electric vehicles are stored and classified in a computer system, along with a vehicle ID that identifies the respective vehicle. This classification is achieved by grouping vehicles with similar driver data and / or similar vehicle data into interest groups. This approach is based on the realization that drivers whose vehicles have similar or even identical driver data and / or vehicle data are relatively likely to also have similar interests and, to that extent, commonalities.At a meeting for a shared charging stop, drivers can then have a lively exchange, making the waiting time during the charging stop pleasant, entertaining, and memorable. This significantly improves the acceptance of the charging stops for drivers.

[0011] The method proposes that several drivers of battery-electric vehicles each calculate a route using a navigation device, each of which includes at least one charging stop. The calculated routes are transmitted to the computer system together with the respective charging stop and the associated vehicle ID. Subsequently, at least two vehicles are identified based on the vehicle ID. These vehicles are assigned to the same interest group and whose associated routes each have a charging stop, which fall within similar time windows and whose locations are within a predetermined local radius. The time windows of the charging stops of the at least two routes are similar in particular if they overlap in time, resulting in a significant simultaneous stopping time period.The local radius can be predetermined in such a way that a maximum detour and / or a maximum detour time, i.e., a maximum time required for the detour, for example, 5 minutes, can result. The radius and / or a maximum detour and / or a maximum detour time can be determined, in particular, by the respective driver.

[0012] The drivers of the vehicles identified in this way are informed that it is possible to modify the respective calculated route so that at least one charging stop on the route coincides in time and location with a charging stop of another vehicle in the same interest group, forming a joint charging stop. If at least two of the drivers informed in this way use this option to modify the calculated route, the calculated routes of the two vehicles are modified so that the charging stops of the two routes that fall within the same time window and are located within the same geographical radius coincide in time and location to form a joint charging stop. This means that there is a relatively high probability that both vehicles will arrive at the location of the joint charging stop within the determined time window, allowing the drivers to spend the charging stop together. In the example of two routes, the following possibilities arise.The first route provides for a charging stop at a first charging point located at a first location. The second route provides for a charging stop at a second charging point located at a second location. In the first case, the first location and the second location are identical. In this case, neither route needs to be modified. It only needs to be ensured that there is a charging station with at least two charging points at the location in question. The shared charging stop then occurs automatically. In a second case, the second location for the first route represents a shorter detour than the first location for the second route. In this case, the first route is modified so that the second location is used for the shared charging stop. In a third case, the second location represents a longer detour for the first route than the first location in the second route.In this case, the second route is modified so that the shared charging stop takes place at the first location. In a fourth case, a third charging station with at least two charging points can be shown at a third location, which represents a relatively short detour for both routes. In this case, both routes are modified so that the third location is used as the shared charging stop. The same applies to three or more vehicles.

[0013] The navigation device can typically be an internal component of the vehicle. This automatically allows the navigation device to know the vehicle battery charge level, the vehicle ID, and vehicle data and / or driver data. Alternatively, the method described here can also be implemented if the navigation device is external to the vehicle. In particular, the navigation device can also be a navigation app or program running on a smartphone, tablet computer, or laptop computer. The vehicle data and / or driver data, the vehicle ID, and the vehicle battery charge level must then be transmitted to the external navigation device in an appropriate manner.

[0014] The computing arrangement can be configured as a backend computer or a backend server. The computing arrangement can comprise one or more computers or one or more servers. The computing arrangement can also be provided in a cloud or be formed by a cloud.

[0015] In the present context, a ‘configuration’ corresponds to a ‘design’ and / or a ‘means’ and / or a ‘programming’, so that the expression ‘configured so that’ is synonymous with the expression ‘designed so that’ and / or ‘arranged so that’ and / or ‘programmed so that’.

[0016] The computer system conveniently knows the geographical locations of a large number of charging points that could be used as a charging stop. This makes it particularly easy for the computer system to find a charging point suitable for a shared charging stop. The relevant data is stored in the computer system.

[0017] The respective navigation device typically has access to an internal memory in which all necessary navigation data and the locations of the charging stations can be retrieved, allowing the navigation device to calculate the respective route, including the charging stop, offline. Alternatively, it is also conceivable for the navigation device to determine the respective route, including the charging stop, through communication with the computer system, i.e., online. This ensures that the navigation device and the computer system have access to the geographical data of the same charging stations.

[0018] The respective charging stop expediently includes the geographical location of at least one charging point. For the joint charging stop, only those charging stations with two or more charging points for one vehicle each are considered.

[0019] The respective route, which the respective driver determines using the navigation system, leads from the current vehicle location to a destination specified by the driver.

[0020] According to an advantageous embodiment, the vehicle data can be at least one member of the following group: vehicle brand, such as Mercedes-Benz, BMW, Porsche, VW and the like, vehicle model, such as A-Class, 3 Series, Taycan, IG.3, and the like, vehicle type, such as sedan, station wagon, convertible, off-road vehicle, SUV, sports car, camper and the like, vehicle equipment, such as fragrance device, entertainment system, trailer and the like, vehicle configuration, such as sports configuration, tuning configuration, comfort configuration, luxury configuration.

[0021] The driver data may include at least one member from the following group: driver characteristics, such as traveling alone, traveling with family, etc., driving behavior, such as on-road, off-road, long-distance, short-distance, etc., personal data, such as gender, age, partner status, number of children, dog owner, radio stations listened to, music genres listened to, destination city, destination country, etc.

[0022] The vehicle ID represents a vehicle identification document that can be used to uniquely identify the respective vehicle. The vehicle ID can be formed, for example, by a vehicle's chassis number or a vehicle registration number.

[0023] According to an advantageous embodiment, it can be provided that the identification of vehicles assigned to the same interest group, whose associated routes each have a charging stop, which fall within similar time windows and are located within a predetermined local radius, is carried out continuously, so that the drivers of the identified vehicles are informed, even while driving along the respective calculated route, that the possibility of modifying the calculated route exists. Accordingly, even while driving along the route, the possibility of modifying the respective calculated route can be demonstrated such that at least one charging stop on the route coincides in time and location with a charging stop of another vehicle in the same interest group.Particularly on longer routes, the opportunity for a joint charging stop may only arise during the course of the route, especially if shorter routes of other vehicles are calculated later and accordingly brought to the attention of the computer system later.

[0024] In another embodiment, if three or more vehicles are identified that are assigned to the same interest group and whose associated routes each have a charging stop, fall within similar time windows, and are located within a predetermined local radius, priority may be given to informing, or only informing, those drivers with the greatest consistency in driver and / or vehicle data about the possibility of modifying the calculated route. This increases the likelihood of an entertaining, stimulating conversation among the drivers during the shared charging stop.

[0025] In another advantageous embodiment, it can be provided that vehicle groups are generated in the computer arrangement in which vehicles are grouped together whose routes have been modified for joint charging at the same charging stop. These vehicle groups therefore contain vehicles whose drivers have already met at a joint charging stop. In the event that three or more vehicles are identified that are assigned to the same interest group and whose associated routes each have a charging stop, that fall within similar time windows and are within a predetermined local radius, priority is given to, or only to, those drivers whose vehicles are in the same vehicle group about the option of modifying the calculated route. In this way, a vehicle network orA driver network should be created so that drivers who have met at least once before can meet up for joint charging stops. This provides additional topics of conversation, making the charging stop more entertaining and enjoyable.

[0026] In another advantageous embodiment, it can be provided that the computer arrangement also offers the drivers who use the option to modify the calculated route the option of forming a driver group whose members have met at a common charging stop as a result of the method, wherein this driver group is stored in the computer arrangement. In the event that three or more vehicles are identified that are assigned to the same interest group and whose associated routes each have a charging stop that fall within similar time windows and are within a predetermined local radius, priority is given to, or only to, those drivers who are members of the same driver group about the option to modify the calculated route. In this way, the drivers are given the opportunity to actively network with one another, namely via the driver group.In this way, personal interests can be optimized, which promotes entertaining charging stops.

[0027] According to beneficial further training, drivers can be offered the opportunity to add other drivers to the driver group, even if they haven't met these other drivers through the process at a joint charging stop. For example, drivers can add like-minded or friendly drivers to the respective driver group.

[0028] A system according to the invention for suggesting charging stops along routes of battery-electric vehicles comprises a computer arrangement configured to carry out the method of the type described above. Furthermore, the system comprises a communication device configured to enable communication between the computer arrangement and the vehicles for data exchange or data transmission.

[0029] A battery-electric vehicle according to the invention comprises a vehicle battery, a navigation device, a communication device, and a control device. The navigation device is configured such that it can calculate a route, taking into account a current state of charge of the vehicle battery, which route can include at least one charging stop depending on the state of charge. The communication device is configured such that it can communicate with an external computer arrangement. The control device is coupled to the navigation device and to the communication device and is also configured such that the vehicle can communicate with the computer arrangement of the aforementioned system for data transmission or data exchange and can participate in the method of the type described above.

[0030] Further important features and advantages of the invention emerge from the subclaims, from the drawings and from the associated description of the figures based on the drawings.

[0031] It is understood that the features mentioned above and those to be explained below can be used not only in the respective combinations specified, but also in other combinations or on their own, without departing from the scope of the invention. Components mentioned above and those to be mentioned below of a higher-level unit, such as a device, a device, or an arrangement, which are designated separately, may form separate parts or components of this unit or be integral areas or sections of this unit, even if this is shown differently in the drawings.

[0032] Preferred embodiments of the invention are illustrated in the drawings and are explained in more detail in the following description, wherein the same reference numerals refer to the same or similar or functionally identical components.

[0033] They show, schematically,

[0034] Figure 1 is a diagram illustrating a method, Figure 2 is a flow chart illustrating the method.

[0035] According to Figure 1, a system 1 configured to suggest charging stops 2 along routes 3 to a destination 4 of battery-electric vehicles 5 comprises a computer arrangement 6 and a communication device 7. The computer arrangement 6 is represented in Figure 1 by a cloud symbol and can comprise one or more computers and / or servers. The computer arrangement 6 is configured to carry out a method 8, which is explained in more detail below with reference to Figure 2. The communication device 7 is configured to enable communication between the computer arrangement 6 and the vehicles 5. The communication is shown in Figure 1 with a dashed line and represents, in particular, a data exchange 9 or data transmission 9.

[0036] The respective battery-electric vehicle 5 has a vehicle battery 10, a navigation device 11, a communication device 12, and a control device 13. The navigation device 11 is configured such that it can calculate a route 3 to the destination 4, taking into account a current state of charge of the vehicle battery 10, which route 3 can include at least one charging stop 2 depending on the current state of charge. The communication device 12 is configured such that it can communicate with the computer arrangement 6. The control device 13 is coupled to the navigation device 11 and to the communication device 12 and is also configured such that the vehicle 5 can communicate with the computer arrangement 6 and can participate in the method 8.

[0037] According to Figure 2, the method 8 comprises a step 14 in which the computer arrangement 6 collects and stores driver data 15 and / or vehicle data 16 from a plurality of battery-electric vehicles 5, together with a vehicle ID 17 that uniquely identifies the respective vehicle 5. In a subsequent step 18, the collected driver data 15 and vehicle data 16 are classified in order to generate several different interest groups 19, which are symbolized by rectangles within step 18 in Figure 2. Within the respective interest group 19 there are then several battery-electric vehicles 5 that have similar driver data 15 and / or similar vehicle data 16. In Figure 2, the driver data 15, the vehicle data 16, and the vehicle ID 17 are shown for only two vehicles 5, representative of a large number of vehicles 5.

[0038] In a step 20 of the method 8, several drivers of battery-electric vehicles 5 each generate a route 3 to a destination 4 using the navigation device 11, each route including at least one charging stop 2. According to Figure 1, the navigation data of the navigation device 11 for the respective charging stop 2 includes a geographical location 21 of a charging point 22 and a time window 23 during which the charging stop 2 is to take place.

[0039] In the example of Figure 1, the two vehicles 5 form a first vehicle 5' and a second vehicle 5". The navigation device 11 of the first vehicle 5' calculates a first route 3', which includes a first charging stop 2' and leads to a first destination 4'. The first charging stop 2' of the first route 3' thus includes a first location 21' of a first charging point 22' and a first time window 23'. The navigation device 11 of the second vehicle 5" determines a second route 3" to a second destination 4" and includes a second charging stop 2". The second charging stop 2" includes a second location 21" of a second charging point 22" and a second time window 23".

[0040] According to Figure 2, the calculated routes 3 with the respective charging stop 2 and the associated vehicle ID 17 are transmitted to the computer arrangement 6 in a step 24. In a step 25, the computer arrangement 6 examines the incoming routes 3 and attempts to identify at least two vehicles 5 based on the vehicle ID 17 that are assigned to the same interest group 19 and for which the associated routes 3 each have a charging stop 2, that fall within similar time windows 23 and whose locations 21 are within a predetermined local radius. In Figure 1, this is illustrated by the fact that between the first location 21' and the second location 21" there is a third location 21, at which a charging station 38 with at least two charging points 22 is located. This third location 21 is therefore suitable as a common third charging stop 2'" or common charging stop 2'".

[0041] According to Figure 2, in a step 26, the computer arrangement 6 informs the drivers of the two vehicles 5 about the possibility of modifying the respectively calculated route 3 such that at least one charging stop 2 of the route 3 coincides in time and location with a charging stop 2 of another vehicle 5 of the same interest group 19, so that instead of the currently calculated charging stop 2, the common charging stop 2'" is approached. In a subsequent step 27, the drivers of the two vehicles 5 can decide whether or not they wish to use this option to modify the calculated route 3. If yes, the decision is positive, which is symbolized in Figure 2 by a plus (+). If no, i.e. if at least one of the two drivers decides against modifying the calculated route 3, the decision is negative, which is symbolized in Figure 2 by a minus (-).If no modification is desired, the method 8 follows a path 28 and reaches a step 29 in which the navigation is continued along the calculated route 3 to the calculated charging stop 2.

[0042] However, if the decision in step 27 is positive, the method 8 follows a path 30 and reaches a step 31, in which the computer arrangement 6 modifies the routes 3 of the two vehicles 5. After the computer arrangement 6 has calculated the two modified routes 3', 3", these are transmitted and adopted in a step 32 to both vehicles 5', 5" or the associated navigation devices 11. Subsequently, the respective vehicle 5', 5" navigates according to step 29 to the common charging stop 2'".

[0043] In Figure 1, the modified first route 3' leads to the shared charging stop 2'" and from there to the first destination 4'. The modified second route 3" now also leads to the shared charging stop 2'" and from there to the second destination 4". The two modified routes 3' and 3" are synchronized with regard to the shared charging stop 2'" such that this shared charging stop 2'" largely coincides in time and place for both vehicles 5', 5" or for both modified routes 3', 3". This allows the drivers to meet and exchange information, which is symbolized in Figure 1 at 33 by two people talking. After the shared charging stop 2'", both vehicles 5', 5" navigate independently of one another to their respective destinations 4', 4" in a step 34. Upon reaching the respective destination 4, the method is terminated in a step 35.

[0044] It is clear that the method 8 can also be carried out for more than two vehicles 5 simultaneously. When determining a possible common charging stop 2', the computer arrangement 6 also takes into account the number of charging points 22 present there.

[0045] In Figure 2, step 18 indicates that different vehicle groups 36 can also be formed within the interest communities 19, in which vehicles 5 are grouped together, in which the routes 3 have been modified for joint charging at the common charging stop 2'". This assigns vehicles 5 to a vehicle group 36 that have already met at a common charging stop 2'" by modifying route 3. During the identification carried out in step 25 of vehicles 5 whose associated routes 3 each have a charging stop 2, which fall within similar time windows 23 and whose locations 21 are within a predetermined local radius, the affiliation to the vehicle groups 36 can now be taken into account.For example, it can be provided that in step 26, preferably those drivers whose vehicles 5 are in the same vehicle group 36 are informed about the possibility of modifying the calculated route 3.

[0046] Likewise, in Figure 2, step 18 indicates that the computer arrangement 6 provides drivers with the option of creating driver groups 37 within the interest communities 19, whose members have met at a joint charging stop 2'" using method 8. These vehicle groups 37 can then be taken into account in step 25 when identifying the vehicles 5 whose charging stops 2 fall within similar time windows 23 and whose locations 21 can be within a predetermined local radius. In step 26, those drivers who are members of the same driver group 37 can then be preferentially informed about the possibility of modifying the calculated route 3. Optionally, the drivers can also be given the option of adding further drivers to the respective driver group 37 of which they are a member, even if they have not met these drivers at a joint charging stop 2'" using method 8.
