Description

[0001] The invention relates to a method for determining a supply area of ​​a charging station for a battery-electric motor vehicle. The invention also relates to a method for determining a suitable parking location for a charging process of a battery-electric motor vehicle.

[0002] So-called charging stations or charging posts are used to charge the traction battery of a battery-electric vehicle. To this end, a charging cable of the charging station is connected to a charging socket of the motor vehicle.

[0003] The charging cables of charging stations are usually short, so that the supply area, ie the area around the charging station within which the battery-electric motor vehicle can be supplied with electrical energy, is limited.

[0004] It is therefore of interest to users of battery-electric vehicles to know before the charging process begins which parking spaces are suitable for a charging process at a selected charging station and whether the charging station should be approached forwards or backwards depending on the position of the charging socket on the vehicle.

[0005] Patent document DE 10 2015 208 229 A1 discloses a method for driver assistance in a motor vehicle that is at least partially electrically driven. In the method, location data of a charging station are acquired, which location data represent the geographical locations of a large number of charging stations. The approach of the motor vehicle to the charging station is detected if a plurality of criteria are met, wherein one of the plurality of criteria is a distance criterion, which is met if the distance between the geographical location of the motor vehicle that corresponds to the vehicle location data and the location of the charging station that corresponds to the charging station location data is less than or equal to a preset threshold value. When the approach of the motor vehicle to the charging station is detected, an output is generated to an output unit in the motor vehicle, wherein the output indicates to the motor vehicle driver the location of the charging interface on the motor vehicle.

[0006] Patent document DE 10 2012 223 057 A1 discloses a method for assisting a driver in a driving maneuver. In this method, in order to follow a trajectory, either the driver assistance system gives the driver instructions for carrying out the necessary steering adjustments and longitudinal guidance, or the driver assistance system automatically carries out the steering adjustments and, if necessary, longitudinal guidance. In this method, it is provided that the trajectory is provided by the driver assistance system, which receives the trajectory via a communication unit from a unit independent of the vehicle.

[0007] Patent document DE 10 2018 213 968 A1 discloses a driver assistance system for automated maneuvering of a motor vehicle. The driver assistance system is configured to determine a driving trajectory based on a driving path manually driven by a driver with a motor vehicle during a recording process, at the end of which the vehicle is located at an actual target position with an actual target orientation, and to maneuver the motor vehicle with at least automated lateral guidance based on the previously determined driving trajectory.

[0008] The object of the present invention is to determine the supply range of a charging station for battery-electric vehicles in order to be able to specify a parking location suitable for a charging process of a traction battery of a battery-electric vehicle without requiring additional maneuvers.

[0009] In order to solve the technical problem to be solved by the present invention, a method for determining the supply area of ​​a charging station for battery-electric motor vehicles is proposed, the method comprising the following steps: positioning the motor vehicle at the charging station, confirming an activated charging process, determining at least one geographical location that can be assigned to the motor vehicle or a part of the motor vehicle, assigning at least one geographical location and / or a geographical area that can be assigned to the geographical location to the supply area of ​​the charging station, and storing or updating a data set for the charging station, wherein the data set includes information about the supply area.

[0010] The charging station may be, in particular, an electrical charging station or charging post which serves to charge an energy storage device, in particular a traction battery, of a battery-electric motor vehicle.

[0011] The method can be carried out in particular using a data processing device of the motor vehicle and / or an external data processing device.

[0012] The supply range of a charging station is understood to be that area around the charging station within which a battery-electric motor vehicle can be supplied with electrical energy, ie in particular that area which can be reached by a charging line belonging to or assigned to the charging station.

[0013] According to the method, the motor vehicle is positioned at or near a charging station, in particular by the vehicle driver. It is then determined whether an active charging process is present. If an active charging process is detected, this means that a charging station is present in the direct vicinity of the current vehicle position. Furthermore, charging stations can be classified essentially as AC charging stations or DC charging stations, depending on the charging power and the type of plug used.

[0014] According to the method, at least one geographical location that can be assigned to the motor vehicle or a part of the motor vehicle is also determined, and the determined geographical location or the geographical area that can be assigned to the geographical location is assigned to the supply area of ​​the charging station. Therefore, if the presence of an active charging process is confirmed, the geographical location that can be assigned to the motor vehicle or the part of the motor vehicle is obviously suitable for charging the battery of the battery-electric motor vehicle. The geographical location and / or the geographical area that can be assigned to the geographical location is therefore assigned to the supply area of ​​the charging station.

[0015] A geographic area may be a limited area around a geographic location that can be assigned to a motor vehicle or a part of a motor vehicle. For example, a geographic area may be an area with a radius of, for example, 20 cm to one meter around a geographic location.

[0016] The geographical area may also be a storage area for the motor vehicle, which is marked, for example, by a storage area marking and which covers or includes the geographical location.

[0017] The data set for the charging station is then stored and / or updated, wherein the data set includes information about the supply area. The information about the supply area can thus be retrieved by calling up the data set. For a further charging process, a suitable parking position for the motor vehicle for charging at the respective charging station can then be determined before the start of the charging process using the information about the supply area.

[0018] The data set can be used, for example, to operate a navigation device so that it displays both the location of the charging station and the associated supply area and / or suitable parking positions. In addition, the data set can also be used in automated parking systems or driver assistance systems that assist the driver with driving instructions when parking at a charging station.

[0019] It is preferably provided that the information about the supply area comprises at least one geographical location assigned to the supply area and / or a geographical area assignable to a geographical location.

[0020] Thus, it is possible to determine from the information about the supply area which geographical location or geographical area was previously determined to be suitable for charging of battery-electric vehicles. In addition, the information about the supply area may also include information about the location of the respective charging post and / or identification information about the charging post, such as an identification number, the type of charging post (AC or DC charging station) and other information.

[0021] It is further advantageously provided that the geographical area that can be assigned to the geographical location is a limited area around the geographical location. For example, the geographical area that can be assigned to the geographical location can be a circular area around the geographical location, which circular area has a radius of preferably at least 20 cm, more preferably at least 50 cm, and even more preferably at least 1 m. Therefore, by storing the geographical area in the data set, instead of assigning individual points to the supply area, a continuous geographical area in the vicinity of the charging station is marked as the supply area. In the case where only the geographical location is stored in the data set, it can also be provided that the continuous geographical area is calculated from the geographical location by a corresponding method.

[0022] It can furthermore advantageously be provided that the geographical location assignable to the motor vehicle is the vehicle position during the charging process.

[0023] The vehicle position can be determined, for example, by a GPS system. Thus, by storing the vehicle position as a geographical location in the data set, the information about the supply area includes those vehicle positions at which battery-electric motor vehicles can be supplied with electrical energy by the charging station.

[0024] Furthermore, it may preferably be provided that the geographical location assignable to a part of the motor vehicle is the position of a charging socket of the motor vehicle during the charging process.

[0025] Depending on the type of vehicle, the charging socket is located at the front, rear or side of the motor vehicle. Since there may be different installation positions of the charging socket on the motor vehicle, it can be provided that the position of the charging socket of the motor vehicle during the charging process is selected as the geographical location instead of the vehicle position determined, for example, by a GPS system. For this purpose, additional information about the motor vehicle, such as the position of the charging socket on the motor vehicle, is required if necessary, so that the position of the charging socket of the motor vehicle during the charging process can be determined from the vehicle position using this additional information.

[0026] Thus, by using the position of the motor vehicle charging socket during the charging process as the geographical location, the vehicle position is not necessarily stored, but rather the geographical location or geographical area that can actually be reached by the charging line of the charging station is assigned to the supply area.

[0027] Furthermore, it may be advantageously provided that the vehicle position and the vehicle orientation are determined, and that the position of the charging socket of the motor vehicle during the charging process is determined based on the vehicle position and the vehicle orientation.

[0028] In particular, in order to determine the position of a motor vehicle charging socket during a charging process, provision can be made to determine the vehicle orientation in addition to the vehicle position. The determined vehicle orientation can then be used to determine the position of the charging socket of the motor vehicle during the charging process based on the vehicle position and the vehicle orientation, wherein further information about the motor vehicle, such as the position of the charging socket on the motor vehicle, may also be required.

[0029] Preferably, it may be provided that data from a GPS system and / or data from a surroundings sensor system of the motor vehicle, in particular a camera device and / or a radar device, are used to determine the vehicle position.

[0030] Therefore, on the one hand, the data of the GPS system can be used to determine the vehicle position. However, the data of the GPS system is usually not sufficient to ensure sufficiently accurate determination of the vehicle position or the charging socket position derived therefrom. Therefore, in order to improve the accuracy of the vehicle position determination and / or the charging socket position determination, other data, such as data from the vehicle's environmental sensor system, can also be used. For example, the position of the motor vehicle relative to the storage surface markings or other markings on the roadway can be determined by a camera device. In addition, the vehicle position or the charging socket position derived therefrom can be determined relative to other objects in the environment, for which the precise GPS coordinates are known. Other objects can be buildings or the charging station itself.

[0031] Furthermore, it may preferably be provided that data from a compass and / or a GPS system and / or data from a surroundings sensor system of the motor vehicle, in particular a camera device and / or a radar device, are used to determine the vehicle orientation.

[0032] The determination of the vehicle orientation can also be improved, for example, by using data from a sensor system for the vehicle's surroundings, such as data from a camera or radar device in particular. The vehicle orientation can be determined more precisely by detecting, with a camera, a marking on a storage surface or other markings on the roadway. Additionally or alternatively, compass data can be used. In particular, the vehicle position, in particular the position of the charging socket during the charging process and the vehicle orientation can be determined precisely by combining GPS information, camera or radar information, and compass information.

[0033] Furthermore, it may be advantageously provided that the charging station is identified, wherein map information and / or data of a GPS system and / or data of a surrounding sensor system of the motor vehicle, in particular a camera device and / or a radar device, are used to identify the charging station.

[0034] In many cases, there are multiple charging stations or fast charging posts set up side by side at the charging location. In order to ensure that the supply area is accurately assigned to a specific charging station even in this case, it can be provided that the charging station is identified. For this purpose, on the one hand, map information about the corresponding charging station, for example provided by a navigation system, can be used and compared with the vehicle position determined using GPS data, for example. In addition, the environmental sensor system of the motor vehicle can be used to identify the charging station. Thus, for example, a charging line connected to the motor vehicle during the charging process can be identified from the image data of the camera device by a correspondingly trained machine learning method and the charging line can be traced back to the charging station assigned to the charging line. In this way, the charging station can be accurately located or identified.

[0035] The aforementioned machine learning method is preferably used in conjunction with a backend server to which the vehicle is in communication connection. This means in particular that the database on which the machine learning method works is pre-stored on the backend server. The machine learning method is preferably performed on the backend server using the data stored on the backend server.

[0036] Furthermore, it can be provided that the charging station transmits identification information to the motor vehicle by radio or via a charging cable, which identification information can contain the exact geographical coordinates of the charging station or these geographical coordinates can be derived from the identification information. Thus, the location of the charging station and the assignment of the supply area to the corresponding charging station become possible.

[0037] In order to improve the determination of the vehicle position and / or the vehicle orientation and / or the identification of the charging station, it can also be provided that, in particular by means of a camera device or a radar device of the motor vehicle, data, in particular images or radar data, are recorded when approaching the charging station before the start of the charging process or when leaving the charging station after the end of the charging process and used for determining the vehicle position, the vehicle orientation and / or for identifying the charging station. This is particularly advantageous in the case where, in the case of a static image recording of the position, important image parts, such as the charging pile or the charging station itself, cannot be directly identified or detected due to darkness or other obstacles. In this case, additional data, such as images or radar data, can help determine the vehicle position and / or the vehicle orientation and / or identify the charging station when approaching or leaving the charging station.

[0038] In addition, other charging stations can be searched for in the immediate surroundings. It can be assumed that there are usually a plurality of charging stations located in the vicinity and that they are also of the same structure.

[0039] Furthermore, it may be advantageously provided that a machine learning method is used to determine the vehicle position and / or the vehicle orientation and / or to identify the charging station.

[0040] For this purpose, it can be provided that a corresponding machine learning method, for example a neural network, is trained using the corresponding data.

[0041] It can furthermore be advantageously provided that the storage surface is assigned to the supply area if the geographical location and / or a geographical area assignable to the geographical location is encompassed by the storage surface, wherein preferably a suitable vehicle orientation of the motor vehicle is additionally assigned to the supply area.

[0042] Thus, for example, a storage surface marked by a storage surface mark or other mark on the roadway can be determined. If the motor vehicle is located on the storage surface during the charging process and / or the geographical position or the geographical area that can be assigned to the geographical position is located on the storage surface or is included by the storage surface, the entire storage surface can also be assigned to the supply area. This makes it easier for the vehicle user to find a suitable parking position for the charging process. If the storage surface is assigned to the supply area, it can be particularly provided that the appropriate vehicle orientation of the motor vehicle is additionally assigned to the supply area. In this way, the following situation may occur, that is, the supply area is configured with a storage surface because at least one position on the storage surface can be provided with electrical energy by the charging station. However, if the entire storage surface cannot be provided with electrical energy due to the short length of the charging cable, it is advantageous to have additional information about whether the vehicle driver should park the motor vehicle forward or backward on the storage surface so that the storage surface is marked as a suitable parking position without restriction. In addition to the appropriate vehicle orientation of the motor vehicle, information about the position of the charging socket on the motor vehicle can also be stored together with information about the supply area in the data set. This is achieved that the data set can also be used by other motor vehicles, such as charging sockets with different positions.

[0043] Preferably, provision may be made for the method steps to be carried out by a plurality of motor vehicles and / or charging stations and / or for a plurality of charging processes.

[0044] Thus, a plurality of geographical locations or geographical areas suitable for a charging process can be determined for a charging station or a plurality of charging stations, and one or more supply areas can be gradually restricted more precisely. If a charging station is approached multiple times and different geographical locations and / or geographical areas and / or storage areas and / or different motor vehicles are used in this process, all suitable geographical locations or assignable geographical areas and / or storage areas can be added to the data set about the charging station.

[0045] As a result, the method can be advantageously used, in particular for an entire fleet of vehicles.

[0046] Preferably, the data set with information about one or more supply areas for the respective charging post can be transmitted to a backend or external server.

[0047] In a preferred embodiment, it is provided that a plurality of motor vehicles equipped with a communication interface retrieve information and / or data sets from a backend or external server.

[0048] The method may also be used within the scope of an automatic parking system or a system which assists the driver with driving instructions when parking at a charging station.

[0049] After the vehicle driver has selected a charging station, either the automatic parking system or the system for assisting the driver can determine the supply area by calling up the corresponding data set and autonomously perform parking at the charging station or assist the driver in parking by means of driving instructions. Preferably, provision can be made for a suitable parking location for the motor vehicle to be determined based on the supply area and / or a geographical location assigned to the supply area and / or a geographical area assignable to the geographical location, preferably by means of a static method.

[0050] If there are a plurality of assigned geographical locations and / or geographical areas and / or storage areas for a charging station, which have been determined in a plurality of charging processes and / or by a plurality of motor vehicles, suitable parking positions for motor vehicles can be determined from the supply areas thus determined by statistical methods. Thus, in particular parts of the supply area that are difficult to access can be marked as suitable but disadvantageous by statistical methods, and in particular parts of the supply area in which a charging cable can be connected to a charging socket of a motor vehicle without problems can be marked as particularly suitable.

[0051] A further solution to the technical problem to be solved by the present invention is to provide a method for determining a suitable parking position for a charging process of a battery-electric motor vehicle, the method comprising the following steps: determining a charging station, calling up a data set for the charging station created by the above method, calling up information about the supply area of ​​the charging station, and using the supply area to determine a suitable parking position of the motor vehicle at the charging station for the charging process.

[0052] Thus, a vehicle driver who wants to charge the traction battery of his motor vehicle can determine the charging station that should be used to charge the battery of the motor vehicle. The determination of the charging station can be performed by the direct selection of the vehicle driver, but the charging station can also be determined, for example, by the proximity to the charging station determined by the vehicle sensor mechanism. According to the method, a data set for the charging station determined by the aforementioned method is called, and information about the supply area of ​​the charging station is called, which information includes, for example, the geographical location and / or the geographical area and / or the vehicle orientation and / or the storage surface. This information can then be displayed to the vehicle driver, for example, on the display of the navigation device. It is also possible that an automated parking system or a driver assistance system uses this information to determine a suitable parking position for the motor vehicle at the charging station for the charging process. It can also be provided that the determination of the charging station is completed by the navigation device, wherein in this case it is preferred that all charging stations in the map area displayed by the navigation device are selected. In this case, all supply areas of all displayed charging stations can be displayed on the navigation area.

[0053] Another solution to the technical problem to be solved by the present invention is to provide a system for executing the above method.

[0054] The present invention will be described in detail below with reference to the accompanying drawings.

[0055] In the attached figure

[0056] Figure 1 A flow chart of a method for determining a supply area of ​​a charging station is shown, and

[0057] Figure 2 A top view of a battery-electric motor vehicle is shown parked near a charging station.

[0058] Figure 1 A flow chart showing a method 100 according to the invention for determining a supply area 10 of a charging station 11 for a battery-electric motor vehicle 12 is shown. Figure 2 Provide a more detailed explanation. Figure 2 A top view of a battery-electric motor vehicle 12 is shown which is parked adjacent to a charging station 11 in order to carry out a charging process.

[0059] In a first method step S1, a motor vehicle 12 is positioned at or in the vicinity of a charging station 11. In a second method step S2, it is determined whether a charging process is active. In the case of an active charging process, a charging line 13 of the charging station 11 is connected to a charging socket 14 of the motor vehicle, and electrical energy is supplied from the charging station 11 to the battery-electric motor vehicle 12 via the charging line 13. Therefore, if an active charging process is determined, it is also ensured that a charging process can be performed with the charging station 11 at the location of the battery-electric motor vehicle 12. In a third method step S3, at least one geographical position 15 that can be assigned to the motor vehicle 12 or a part of the motor vehicle 12 is determined. The geographical position 15 that can be assigned to the motor vehicle 12 or a part of the motor vehicle 12 can be, in particular, a vehicle position 15a determined, for example, by a GPS system or a position 15b of the charging socket 14 of the motor vehicle 12 during the charging process. In order to determine the position 15b of the charging socket 14 during the charging process, the vehicle position 15a determined from GPS data and information about the position of the charging socket 14 on the motor vehicle 12 can be used. In other words, the geographical position 15 b of the charging socket 14 during the charging process can be determined from the determined vehicle position 15 a using further information about the position of the charging socket 14 on the motor vehicle 12 .

[0060] In a fourth method step S4, the determined geographical location 15, for example the vehicle location 15a or the location 15b of the charging socket, is assigned to the supply area 10 of the charging station 11. Alternatively or additionally, a geographical area 16a, 16b assignable to the geographical location 15, 15a, 15b can be assigned to the supply area 10. The geographical area 16a, 16b can be a limited area with a radius of, for example, 20 cm around the geographical location 15, 15a, 15b.

[0061] Subsequently, in a fifth method step S5, a data set for the charging station 11 is stored and / or updated, wherein the data set includes information about the supply area 10. The method 100 can be carried out with a plurality of motor vehicles 12 and / or a plurality of charging processes and / or a plurality of charging stations 11, thereby enabling a continuously more precise definition of one or more supply areas 10.

[0062] In a further embodiment of the method 100, a storage surface 18 marked by a storage surface marking 17 can also be assigned to the supply area 10. By assigning the storage surface 18 to the supply area 10, it is easier for the driver of the motor vehicle 12 to find a suitable parking location. If the storage surface 18 is assigned to the supply area 10, it is particularly advantageous to also add the geographical position 15b of the charging socket during the charging process and / or the vehicle orientation 19 to the data set. This is particularly advantageous if the supply area 10 is such that Figure 2In the illustration, the entire storage surface 18 is not covered.

[0063] according to Figure 1 and Figure 2 The determined supply area 10 can also be made available to other motor vehicles via the central server 20 so that these other motor vehicles or their drivers can already be informed of a suitable parking location, for example a suitable storage surface 18 with or without vehicle orientation 19 or of the supply area 10 when approaching a charging station or selecting a charging station 11 for charging their motor vehicle.

[0064] The surroundings sensor system 21 of the motor vehicle 12 can also be used to improve the determination of the supply area 10. For example, the surroundings sensor system 21 can have a camera device 21a and / or a radar device. The vehicle position 15a or the position 15b of the charging socket can be determined more accurately during the charging process by means of the camera device 21a and / or the radar device, in particular in combination with GPS information. Thus, for example, by evaluating the data of the camera device 21a, the storage surface marking 17 or the distance to a known object such as a building can be determined in order to determine the vehicle position 15a more accurately.

[0065] The surrounding sensor system 21 can also be used to precisely locate the charging station 11. Since in common charging locations, a plurality of charging stations are usually arranged side by side, it may be necessary to precisely identify the charging station 11 used. For this purpose, a camera device 21a of the motor vehicle 12 can be used in particular. The charging station 11 can be identified by the camera device 21a when stationary by tracing the charging line 13 to the charging station 11, but it can also be identified when approaching or leaving the charging station 11. In this case, a machine learning method, such as a neural network, can be used to identify the storage surface marking 17 and / or the charging station 11.
