Description

The present invention relates to a method for determining a supply area of a charging station for a battery-electric motor vehicle. The present invention further relates to a method for determining a suitable parking position for charging a battery-electric motor vehicle.

So-called charging stations or charging columns are used to charge the traction batteries of battery-electric vehicles. For this purpose, a charging cable from the charging station is connected to a charging socket on the motor vehicle.

The charging cables of the charging stations are often comparatively short, so that the supply area, i.e. the area around the charging station within which a battery-electric motor vehicle can be supplied with electrical energy, is limited.

It is therefore of interest for a user of a battery-electric motor vehicle to know before the charging process begins which parking positions are suitable for charging 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 motor vehicle .

The DE 10 2015 208 229 A1 discloses a method for driver assistance in an at least partially electrically driven motor vehicle. The method accesses charging station position data, which represents the geographical position of a large number of charging stations. If a number of criteria are met, an approach of the motor vehicle to a charging station is detected, one criterion from the number of criteria being a distance criterion, which is fulfilled when the geographical position of the motor vehicle according to vehicle position data is a distance less than or equal to one predetermined threshold value of the position of the charging station according to the charging station position data. If an approach of the motor vehicle to a charging station is detected, an output is generated to an output unit in the motor vehicle, the output indicating to the driver of the motor vehicle the location at which the charging interface on the motor vehicle is located.

The DE 10 2012 223 057 A1 discloses a method for supporting a driver during a driving maneuver. In the method, in order to follow a trajectory, either the driver is given instructions by a driver assistance system to carry out the necessary steering adjustments and longitudinal guidance, or the steering adjustment and, if necessary, the longitudinal guidance are carried out automatically by the driver assistance system. It is provided that the driver assistance system provides a trajectory that the driver assistance system receives from a unit that is independent of the ego vehicle by means of a communication unit.

The DE 10 2018 213 968 A1 discloses a driver assistance system for automated maneuvering of a motor vehicle. The driver assistance system is set up to determine a travel trajectory in a recording process based on a route manually driven by the driver with the motor vehicle, at the end of which the vehicle is at an actual target position with an actual target orientation, and based on the predetermined travel trajectory To maneuver a motor vehicle with at least automated lateral guidance.

The present invention is based on the object of determining a supply area of a charging station for battery-electric motor vehicles, so that suitable parking positions for a charging process of the traction battery of a battery-electric motor vehicle can be specified without the need for re-shunting.

To solve the problem on which the invention is based, a method for determining a supply area of a charging station for a battery-electric motor vehicle is proposed, comprising the steps of positioning a motor vehicle at a charging station, determining an active charging process, and determining at least one geographical position that can be assigned to the motor vehicle or part of the motor vehicle , Assigning the at least one geographical position and/or a geographical area assignable to the geographical position to the coverage area of the charging station and storing or updating a data record for the charging station, wherein the data record includes information about the coverage area.

The charging station can in particular be an electric charging station or charging station for charging an energy storage device, in particular a traction battery, of the battery-electric motor vehicle.

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

A service area of a charging station is the area around the charging station understood, within which a battery-electric motor vehicle can be supplied with electrical energy, that is, in particular, that area which can be reached by a charging cable belonging or assigned to the charging station.

According to the method, the motor vehicle is positioned, in particular by a vehicle driver, at or near a charging station. It is then determined whether there is an active charging process. If an active charging process is detected, this means that a charging station is in the immediate vicinity of the current vehicle position. Furthermore, a basic classification of the charging station into AC or DC charging stations can be achieved based on the charging power and the type of plug used.

According to the method, at least one geographical position that can be assigned to the motor vehicle or part of the motor vehicle is determined, and the determined geographical position or a geographical area that can be assigned to the geographical position is assigned to the supply area of the charging station. If an active charging process has been detected, the geographical position that can be assigned to the motor vehicle or part of the motor vehicle is obviously suitable for charging the battery of the battery-electric motor vehicle. Therefore, the geographical position and/or a geographical area that can be assigned to the geographical position is assigned to the coverage area of the charging station.

The geographical area can be a limited area around the geographical position that can be assigned to the motor vehicle or part of the motor vehicle.

For example, the geographical area can be an area with a radius of, for example, 20 cm to one meter from the geographical position.

It is also possible that the geographical area is a parking space for the motor vehicle, for example marked by parking space markings, which covers or includes the geographical position.

A data record for the charging station is then saved and/or updated, the data record comprising information about the supply area. Thus, by retrieving the data set, the information about the coverage area can be retrieved. Using the information about the supply area, a parking position for the motor vehicle suitable for charging at the respective charging station can then be determined during a further charging process before the charging process begins.

The data set can be used, for example, to operate a navigation device, so that the navigation device displays both the position of a charging station and the service area associated with the charging station and/or suitable parking positions. The data set can also be used in an automated parking system or a driver assistance system that supports the driver with driving instructions when parking at the charging station.

It is preferably provided that the information about the coverage area includes the at least one geographical position assigned to the coverage area and/or the geographic area that can be assigned to the geographical position.

The geographical position previously determined to be suitable for charging the battery-electric motor vehicle or the geographical area determined to be suitable can therefore be determined from the information about the supply area. Furthermore, the information can also include information about the position of the respective charging station and/or identification information about the charging station, such as an identification number, its type (AC or DC charging station) and other information.

With further advantage it is provided that the geographical area that can be assigned to the geographical position is a limited area around the geographical position.

For example, the geographical area that can be assigned to the geographical position can be a circular area around the geographical position, with a radius of preferably at least 20 cm, more preferably at least 50 cm, even more preferably at least 1 m. By storing a geographical area in the data record, individual points are not assigned to the coverage area, but rather a contiguous geographic area near the charging station is identified as the coverage area. In the event that only geographical positions are stored in the data record, it can also be provided that a coherent geographical area is calculated from the geographical positions using a corresponding method.

With further advantage it can be provided that the geographical position that can be assigned to the motor vehicle is a vehicle position during the charging process.

The vehicle position can be determined, for example, using a GPS system. By storing the vehicle position as a geographical position in the data record, the information about the supply area thus includes those vehicle positions at which a battery-electric motor vehicle can be supplied with electrical energy from the charging station.

Furthermore, it can preferably be provided that the geographical position that can be assigned to a part of the motor vehicle is a position of a charging socket of the motor vehicle during the charging process.

Depending on the vehicle type, the charging socket is located at the front, rear or side of the vehicle. Since different installation positions of the charging socket on the motor vehicle can be present, it can be provided that not the vehicle position determined, for example by means of a GPS system, is selected as the geographical position, but rather the position of the charging socket of the motor vehicle during the charging process. For this purpose, additional information about the motor vehicle may be necessary, such as the position of the charging socket on the motor vehicle, so that the position of the charging socket of the motor vehicle can be determined during the charging process using this additional information from the vehicle position.

By using the position of the charging socket of the motor vehicle as a geographical position during the charging process, the vehicle position is not necessarily saved, but rather the geographical positions or geographical areas that can actually be reached by the charging cable of the charging station are assigned to the supply area.

With further advantage it can be provided that a vehicle position is determined and that a vehicle orientation is determined, and that the position of the charging socket of the motor vehicle is determined during the charging process on the basis of the vehicle position and the vehicle orientation.

In particular, in order to determine the position of the charging socket of the motor vehicle during the charging process, it can be provided that the vehicle orientation is also determined in addition to the vehicle position. The specific 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, where additional information about the motor vehicle, such as the position of the charging socket on the motor vehicle, may be necessary.

It can preferably be provided that data from a GPS system and/or data from an environment sensor system of the motor vehicle, in particular a camera device and/or a radar device, are used to determine the vehicle position.

To determine the vehicle position, the data from a GPS system can be used. However, these are usually not sufficient to ensure a sufficiently precise determination of the vehicle position or the position of the charging socket derived from it. In order to increase the precision of determining the vehicle position and/or determining the position of the charging socket, additional data, such as the data from an environmental sensor system of the motor vehicle, can also be used. For example, the position of the motor vehicle with respect to parking space markings or other markings on the road can be determined using a camera device. In addition, camera information or radar information can be used to determine the vehicle position, or the position of the charging socket derived from it, with respect to other objects in the area for which the exact GPS coordinates are known. The other objects can be buildings or the charging station itself.

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

The determination of the vehicle orientation can also be improved, for example, by using the data from an environmental sensor system of the motor vehicle, such as in particular a camera device or a radar device. Through camera-based detection of parking space markings or other markings on the road, the vehicle orientation can be determined more precisely. Additionally or alternatively, data from a compass can be used. In particular, through the combination of GPS information, camera or radar information and compass information, the vehicle position, in particular the position of the charging socket during the charging process, and the vehicle orientation can be precisely determined.

With further advantage it can be provided that the charging station is identified, with map information and/or data from a GPS system and/or data from an environmental sensor system of the motor vehicle, in particular a camera device and/or a radar device, being used to identify the charging station.

In many cases, several charging stations or fast charging stations are set up next to each other at a charging station. In order to ensure a precise assignment of the supply area to a specific charging station in these cases too, it can be provided that the charging station is identified. For this purpose, map information about the respective charging station, for example provided by a navigation system, can be used and, for example, compared with the vehicle position determined using GPS data. In addition, the vehicle's surroundings sensors can be used to identify the charging station. For example, using an appropriately trained machine learning method from image data from a camera device, the charging cable connected to the motor vehicle during the charging process can be identified and traced back to the charging station assigned to the charging cable. This makes precise regulation or identification of the charging station possible.

The machine learning methods mentioned are preferably used in connection with a backend server with which the vehicle has a communication connection. This means in particular that a database on which the machine learning process works is kept on the backend server. Preferably, the machine learning process is carried out on the backend server using the data stored there.

In addition, it can also be provided that the charging station transmits an identification to the motor vehicle either radio-based or via the charging cable, which contains the precise geographical coordinates of the charging station or from which these geographical coordinates can be derived. This makes it possible to locate the charging station and assign the supply area to the corresponding charging station.

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 with the camera device or the radar device of the motor vehicle, when approaching the charging station before the start of the charging process or when removing it from the Charging station, i.e. after the charging process has ended, data, in particular images or radar data, are recorded and used to determine the vehicle position, vehicle orientation and / or for identifying the charging station. This is particularly advantageous if, in a static image recording position, relevant image parts, such as the charging column or charging station itself, cannot be immediately recognized or detected due to darkness or other obstacles. The additional data, such as images or radar data, can help when approaching or removing from the charging station in order to determine the vehicle position and/or the vehicle orientation and/or to identify the charging station.

You can also search the immediate surroundings for additional charging stations. It can be assumed that there are usually several charging stations nearby and that they are also identical in construction.

With further advantage it can be provided that machine learning methods are used to determine the vehicle position and/or the vehicle orientation and/or to identify the charging station.

For this purpose, it can be provided that the corresponding machine learning method, such as a neural network, is trained with appropriate data.

With further advantage, it can be provided that a parking space is assigned to the service area if the geographical position and/or the geographical area that can be assigned to the geographical position is covered by the parking space, with a suitable vehicle orientation of the motor vehicle preferably also being assigned to the service area.

For example, a parking space marked with parking space markings or other markings on the road can be determined. If the motor vehicle is on this parking space during the charging process and/or the geographical position or the geographical area that can be assigned to the geographical position is on the parking space or is covered by it, then the entire parking space can also be assigned to the supply area. This makes it easier for the vehicle user to find a suitable parking position for charging. If the parking space is assigned to the supply area, it can in particular be provided that a suitable vehicle orientation of the motor vehicle is additionally assigned to the supply area. The case may thus arise, that a parking space is assigned to the supply area because electrical energy can be supplied from the charging station to at least one position on this parking space. However, if the entire parking space cannot be supplied with electrical energy due to the short length of the charging cable, the additional information as to whether the driver should park the motor vehicle forwards or backwards into the parking space is advantageous in order to fully identify the parking space as a suitable parking position. In addition to the suitable vehicle orientation of the motor vehicle, information about the position of the charging socket on the motor vehicle can also be stored in the data record with the information about the supply area. This makes it possible for the data set to also be used by other motor vehicles, which, for example, have a different position of the charging socket.

It can preferably be provided that the method steps are carried out with a large number of motor vehicles and/or charging stations and/or for a large number of charging processes.

A large number of geographical positions or geographical areas suitable for charging processes can therefore be determined for the charging station or for several charging stations and the supply area or areas can be successively restricted more precisely. If a charging station is approached several times and different geographical positions and/or geographical areas and/or parking spaces and/or different motor vehicles are used, all suitable geographical positions or assignable geographical areas and/or parking spaces can be added to the data set for the charging station.

This makes the method particularly advantageous for entire vehicle fleets.

Preferably, the data sets with the information about the supply area(s) for the respective charging stations can be transmitted to a backend or an external server.

In a preferred further development, it is provided that a large number of motor vehicles, which are equipped with a communication interface, retrieve the information and/or data sets from the backend or the external server.

The method can also be used as part of automatic parking systems or systems that support the driver by providing driving instructions when parking at a charging station.

After the driver has selected a charging station, either the automatic parking system or the driver support system can determine the coverage area by retrieving the corresponding data record and automatically park at the charging station or support the driver when parking by providing driving instructions.

Preferably, it can be provided that suitable parking positions for a motor vehicle are determined, preferably by means of static methods, on the basis of the service area and/or the geographical position assigned to the service area and/or the geographical area that can be assigned to the geographical position.

If there are a large number of assigned geographical positions and/or geographical areas and/or parking spaces for a charging station, which were determined during several charging processes and/or by several motor vehicles, a suitable parking position for a motor vehicle can be determined from the supply area thus obtained using statistical methods be determined. In particular, parts of the supply area that are difficult to access can be marked as suitable but unfavorable using the statistical methods, and in particular those parts of the supply area can be marked as particularly suitable in which the charging cable can be connected to the charging socket of the motor vehicle is possible without any problems.

A further solution to the problem on which the invention is based is to provide a method for determining a suitable parking position for a charging process of a battery-electric motor vehicle, comprising the steps of determining a charging station, retrieving a data record for the charging station created using a previously described method, retrieving the information about the supply area the charging station and using the service area to determine a suitable parking position of the motor vehicle at the charging station for a charging process.

A vehicle driver who wants to charge the traction battery of his motor vehicle can thus determine a charging station with which the battery of the motor vehicle is to be charged. The charging station can be determined by direct selection by the vehicle driver, but the charging station can also be determined, for example, by an approach to the charging station determined by means of a vehicle sensor system. Procedurally The data record for the charging station determined using the above-described method is retrieved, and the information about the coverage area of this charging station, which includes, for example, geographical positions and/or geographical areas and/or vehicle orientations and/or parking spaces, is retrieved. This information can then be displayed to the vehicle driver, for example on a display of a navigation device. It is also possible for the information to be used by an automated parking system or a driver assistance system to determine a suitable parking position of the motor vehicle at a charging station for a charging process. It can also be provided that a charging station is determined by a navigation device, in which case all charging stations in the map area displayed by the navigation device are then preferably selected. In this case, all coverage areas of all displayed charging stations can be displayed in the navigation area.

A further solution to the problem on which the invention is based is to provide a system for carrying out a method described above.

The invention is explained in more detail below with reference to the attached figures.

1 shows a flowchart for a method 100 for determining a supply area 10 of a charging station 11 for a battery-electric motor vehicle 12 in accordance with the invention, which with reference to 2 is explained in more detail. 2 shows a top view of a battery-electric motor vehicle 12 parked near a charging station 11 for a charging process.

In a first method step S1, the motor vehicle 12 is positioned at or near a charging station 11. In a second method step S2, it is determined whether a charging process is active. During an active charging process, a charging cable 13 of the charging station 11 is connected to a charging socket 14 of the motor vehicle, and electrical energy is supplied via the charging cable 13 from the charging station 11 to the battery-electric motor vehicle 12. If an active charging process is detected, it is also ensured that a charging process can be carried out 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 in particular be the vehicle position 15a, which is determined, for example, by means of a GPS system, or the position 15b of the charging socket 14 of the motor vehicle 12 during the charging process. To determine the position 15b of the charging socket 14 during the charging process, the vehicle position 15a determined from GPS data as well as information about the position of the charging socket 14 on the motor vehicle 12 can be used. In other words, the geographical position 15b of the charging socket 14 can be determined during the charging process from the determined vehicle position 15a using further information about the position of the charging socket 14 on the motor vehicle 12.

In a fourth method step S4, the determined geographical position 15, for example the vehicle position 15a or the position 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 that can be assigned to the geographical position 15, 15a, 15b can be assigned to the coverage area 10. The geographical area 16a, 16b can be a limited area with a radius of, for example, 20 cm around the geographical position 15, 15a, 15b.

Subsequently, in a fifth method step S5, a data record for the charging station 11 is saved and/or updated, the data record comprising information about the supply area 10. The method 100 can be carried out with a large number of motor vehicles 12 and/or a large number of charging processes and/or with a large number of charging stations 11, whereby a continuously more precise delimitation of the supply area or areas 10 can be achieved.

In a further embodiment of the method 100, it is also possible for the supply area 10 to be assigned a parking space 18 marked by space markings 17. Assigning the parking space 18 to the supply area 10 makes it easier for a driver of the motor vehicle 12 to find suitable parking positions. If the footprint 18 is assigned to the supply area 10, it is particularly advantageous if the geographical position 15b of the charging socket is also selected at the same time during the charging process and/or the vehicle orientation 19 is added to the data record. This is particularly advantageous if the supply area 10, as in 2 shown, does not cover the entire footprint 18.

The one with the after the 1 and 2 The determined supply area 10 can also be made available to other motor vehicles via a central server 20, so that they or their drivers already have a suitable parking position, such as a suitable parking space 18 with or without, when driving off or selecting a charging station 11 for charging their motor vehicle Vehicle alignment 19 or about the supply area 10 can be informed.

To improve the determination of the supply area 10, an environmental sensor system 21 of the motor vehicle 12 can also be used. For example, the environment sensor system 21 can have a camera device 21a and/or a radar device. By means of the camera device 21a and/or the radar device, the vehicle position 15a or the position 15b of the charging socket can be determined even more precisely during the charging process, particularly in conjunction with GPS information. For example, by evaluating the data from the camera device 21a, the parking area markings 17 can be determined or distances to known objects such as buildings can be determined in order to determine the vehicle position 15a more precisely.

The environment sensor system 21 can also be used to precisely determine the charging station 11. Since several charging stations are usually set up next to each other in conventional charging stations, it may be necessary for the charging station 11 used to be precisely identified. In particular, the camera device 21a of the motor vehicle 12 can be used for this purpose. By means of the camera device 21a, the charging station 11 can be identified when stationary by tracking the charging cable 13 to the charging station 11, but also when approaching or departing from the charging station 11. Machine learning methods, such as neural networks, can be used to identify the parking space markings 17 and/or the charging station 11.
