Description

The invention relates to a method for providing information for recognizing a parking possibility for a predetermined vehicle type in a charging infrastructure, a computer program product and a system with a vehicle.

It is known to use vehicle sensor technology to assist the driver when driving to charging stations for electric vehicles. For example, it is known from the document GB2500691B It is known that sensor technology can be used to control and align a vehicle via an inductive charging point.

Before a charging location can even be approached as such, the parking situation in front of a public or semi-public charging station is often an important factor for the success of the charging process for electric or partially electric vehicles. Parking spaces at the charging station that are too narrow or too short can prevent the vehicle from charging at all. In addition, it is important for combinations with electric towing vehicles that there is sufficient space for the towed trailer without blocking other charging stations or having to uncouple the trailer for each public charging process.

It is an object of the present invention to at least partially remedy the above-mentioned disadvantages known from the prior art. In particular, it is an object of the present invention to improve the recognition of a parking space for a charging process of a predetermined vehicle type, in particular at an early stage.

The above object is achieved by a method having the features of claim 1, a computer program product having the features of claim 10 and a system having the features of claim 11. Further features and details of the invention emerge from the respective subclaims, the description and the drawings. Features and details that are described in connection with the method according to the invention naturally also apply in connection with the computer program product according to the invention and/or the system according to the invention and vice versa, so that with regard to the disclosure of the individual aspects of the invention, reference is or can always be made to each other.

• - Erhalt von bildbasierten Umgebungsdaten einer Fahrzeugumgebung eines Fahrzeuges an einem Ladeort einer Ladeeinheit zur Bereitstellung von elektrischer Energie für das Fahrzeug, insbesondere durch eine Kontrolleinheit und/oder von einer Umfeldsensorik des Fahrzeuges,
• - Bestimmen einer Stellflächenstruktur einer Stellfläche zum Abstellen des Fahrzeuges am Ladeort in Abhängigkeit von den Umgebungsdaten, insbesondere durch die Kontrolleinheit,
• - Bewerten der Stellflächenstruktur zum Erkennen der Abstellmöglichkeit, insbesondere auf der Stellfläche, in Abhängigkeit von der vorbestimmten Fahrzeugart, insbesondere durch die Kontrolleinheit,

According to a first aspect of the invention, a method is provided for providing information for identifying a parking option for a predetermined type of vehicle in a charging infrastructure. The method comprises, in particular in the form of method steps:

• - Receiving image-based environmental data of a vehicle environment at a charging location of a charging unit for providing electrical energy for the vehicle, in particular by a control unit and/or from an environmental sensor system of the vehicle,
• - Determining a parking space structure of a parking space for parking the vehicle at the loading location depending on the environmental data, in particular by the control unit,
• - Evaluating the parking space structure to identify the parking option, in particular on the parking space, depending on the predetermined vehicle type, in particular by the control unit,
• - Outputting at least one suitability information about the parking option depending on the evaluation of the parking space structure, in particular by the control unit.

The vehicle can in particular be a motor vehicle, preferably in the form of an electric vehicle. The predetermined vehicle type can preferably comprise vehicles that have a predetermined length, in particular greater than or equal to 5 m, preferably greater than or equal to 7 m. For example, the predetermined vehicle type can comprise, preferably exclusively, trailers and/or trucks. In particular, the predetermined vehicle type can also be referred to as a predetermined vehicle class. The charging infrastructure can in particular be a local, regional and/or global charging infrastructure. For example, the charging infrastructure can comprise the charging location with the charging unit and preferably further charging locations and/or further charging units.

The charging location can be understood in particular as a location where the charging of a vehicle battery, in particular a traction battery, of the vehicle is possible. The charging location includes in particular the parking area. The charging unit can, for example, comprise a public or non-public charging station. For example, the charging unit can have one or more charging plugs for connecting the vehicle battery. The charging location can comprise several charging units.

Image-based environmental data can be understood in particular as sensor data that are at least partially or completely virtual and/or camera-based image data of the vehicle environment. It is conceivable that the sensor data are evaluated and/or processed at least partially or completely locally by a decentralized control unit of the environmental sensor system. In particular, the image-based environmental data can include raw data from the environmental sensor system and/or processed data. The image-based environmental data can preferably be recorded by the environmental sensor system and transmitted to the control unit. The environmental sensor system can be, for example, a camera, in particular a front camera, of the vehicle.

The parking space can in particular form a parking space for parking the vehicle during the charging process. The parking space structure can, for example, comprise boundaries of the parking space, e.g. in the form of road markings and/or curbs. Furthermore, the parking space structure can comprise a position of the charging unit in relation to the parking space. When determining the parking space structure, the environmental data can be evaluated, in particular with further sensor data and/or vehicle data, in order to recognize the parking space structure, i.e. in particular to extract it from the environmental data.

When evaluating the parking space structure to identify the parking option, it can be evaluated whether the parking space is suitable for parking the predefined vehicle type. For example, a length and/or width of the parking space can be compared with the dimensions of the vehicle type. It can be provided that when evaluating the parking space structure, feedback from a driver and/or a customer of the loading unit is expected and/or requested in order to verify an automated evaluation.

The suitability information can include binary information about whether the parking option is available on the parking space. However, it is also conceivable that the suitability information includes more complex information, e.g. evaluation information, a classification and/or a ranking, about the parking option. For example, it can be provided that the parking option can be classified on a scale of an evaluation system based on the suitability information. Outputting the suitability information can include displaying and/or sending the suitability information. For example, the suitability information can be displayed to a driver of the vehicle on a display device and/or sent to a vehicle system of the vehicle and/or to other vehicles.

The suitability information can thus provide information about the charging location, which helps drivers and/or operating systems of the predetermined vehicle type to find a suitable charging location. By taking the image-based environmental data into account, the vehicle is not dependent on any information from an operator of the charging unit. Furthermore, the suitability information can be based on the actual conditions at the charging location and, for example, a change in the charging infrastructure and/or the charging location can be recorded in real time. If the suitability information is provided for other vehicles, for example, when the suitability information is issued, these can assess early on whether the charging location is suitable for them and, if necessary, head for another charging location. For the driver of the vehicle, this also has the advantage that he needs little or no experience to be able to assess the parking options at the charging location, which can, for example, avoid unsuccessful maneuvering.

Furthermore, in a method according to the invention, it can advantageously be provided that the predetermined vehicle type, preferably exclusively, includes trailers, wherein a length of the parking space is determined when determining the parking space structure. In particular, the vehicle can be a vehicle of the predetermined vehicle type, i.e. in particular a trailer. Trailers can be understood to mean vehicles with attached trailers in particular. A trailer can limit the maneuverability. Furthermore, some parking spaces at loading locations can be of insufficient length for the trailers. Based on the length of the parking space, it can be determined whether the parking option is available for the vehicle type. It is therefore particularly advantageous to evaluate the parking space structure for trailers and/or to output the suitability information for trailers.

Furthermore, in a method according to the invention, it can advantageously be provided that when evaluating the parking space structure, the accessibility of the parking space is evaluated based on an access area of the parking space and/or an exit area of the parking space depending on the predetermined vehicle type. The accessibility can be taken into account when outputting the suitability information. For example, the suitability information can include information about the accessibility. It is also conceivable that the accessibility is output with the suitability information in addition to the suitability information. The access area and/or the exit area can be recognized in particular when determining the parking space structure based on the environmental data. The access area can be understood in particular as an area at the loading location over which the vehicle on the parking space can be driven into. The departure area can be understood as an area at the loading location through which the vehicle can leave the parking space. When assessing accessibility, it is preferably checked whether the access area differs from the departure area and/or whether a vehicle of the predetermined vehicle type can drive forwards into the parking space and leave it again. To assess accessibility, for example, a required number of maneuvers and/or steering movements for the predetermined vehicle type can be calculated. Accessibility can therefore form a criterion for assessing the parking space structure. Furthermore, by assessing accessibility, more complex information about the parking option can be provided by outputting suitability information.

• - Erfassen einer Belegungsinformation über einen aktuellen Belegungsstatus der Ladeeinheit, insbesondere durch die Kontrolleinheit,

vorzugsweise wobei ein Abgleich der Belegungsinformation mit den Umgebungsdaten erfolgt und das Ausgeben der Eignungsinformation in Abhängigkeit von der Belegungsinformation und dem Abgleich erfolgt. Die Belegungsinformation kann eine Information über eine aktuelle Anzahl zum Laden verfügbarer und/oder belegter Ladeplätze, Ladeeinheiten und/oder Ladestecker am Ladeort umfassen. Vorzugsweise wird die Belegungsinformation von einem Server erhalten. Beispielsweise kann ein Betreiber der Ladeeinheit die Belegungsinformation bereitstellen. Für den Abgleich kann anhand der Umgebungsdaten überprüft werden, ob ein anderes Fahrzeug auf der Stellfläche und/oder an der Ladeeinheit steht. Dadurch kann die Belegungsinformation, insbesondere in Echtzeit, verifiziert und/oder spezifiziert werden. So ist es denkbar, dass die Ladeeinheit drei oder mehr unterschiedliche Ladestecker, jedoch nur zwei Stellflächen aufweist. Dabei kann der Fall eintreten, dass die Belegungsinformation des Betreibers einen verfügbaren Ladestecker ausweist, bei dem Abgleich der Belegungsinformation und der Umgebungsdaten jedoch festgestellt wird, dass beide Stellflächen belegt sind, d. h. insbesondere keine Abstellmöglichkeit vorhanden ist. Somit kann die Kombination der Umgebungsdaten und der Belegungsinformation eine höhere Genauigkeit und/oder Komplexität für die Einschätzung der Belegungssituation an der Ladeeinheit ermöglichen.Preferably, in a method according to the invention, it can be provided that the method, in particular in the form of a method step, comprises:

• - Recording occupancy information about the current occupancy status of the loading unit, in particular by the control unit,

Preferably, the occupancy information is compared with the environmental data and the suitability information is output depending on the occupancy information and the comparison. The occupancy information can include information about a current number of charging spaces, charging units and/or charging plugs available for charging and/or occupied at the charging location. The occupancy information is preferably obtained from a server. For example, an operator of the charging unit can provide the occupancy information. For the comparison, the environmental data can be used to check whether another vehicle is on the parking space and/or at the charging unit. This allows the occupancy information to be verified and/or specified, in particular in real time. It is conceivable that the charging unit has three or more different charging plugs, but only two parking spaces. It can happen that the operator's occupancy information shows an available charging plug, but when the occupancy information and the environmental data are compared, it is determined that both parking spaces are occupied, i.e. in particular that there is no parking space available. Thus, the combination of environmental data and occupancy information can enable greater accuracy and/or complexity for assessing the occupancy situation at the loading unit.

Furthermore, in a method according to the invention, it is conceivable that when the suitability information is output, the charging unit is localized and the suitability information is integrated into a map. The charging unit can be localized, for example, using geographical position data, e.g. in the form of GPS and/or Galileo data, the charging unit and/or the vehicle. The map can in particular be a virtual map, in particular for navigation. The map can be provided, for example, using geographical data. The map can be two- or three-dimensional. Furthermore, the map can include map data from several charging locations, road data, landscape data, traffic data and/or road data. In particular, the map can be continuously updated. The suitability information can be entered based on the localization of the charging unit in the form of metadata of the charging location. Preferably, the map can be made available to other vehicles, in particular in real time. The suitability information can thus be output as part of swarm data. In particular, the method can use swarm data from multiple vehicles to improve the map and thus enable simplified navigation to a suitable charging location for vehicles of the predetermined vehicle type. Furthermore, by integrating the suitability information into the map, an automated parking process, e.g. in a parking lot, can be enabled and/or improved for the predetermined vehicle type.

• - Erfassen von Fahrzeugdaten des Fahrzeuges bei einem Parkvorgang zum Parken des Fahrzeuges innerhalb der Stellflächenstruktur, insbesondere durch die Kontrolleinheit,

vorzugsweise wobei die Fahrzeugdaten des Fahrzeuges beim Bewerten der Stellflächenstruktur berücksichtigt werden. Die Fahrzeugdaten können insbesondere zur Charakterisierung des Parkvorgangs erfasst werden. Z. B. können die Fahrzeugdaten eine Information über einen Anhänger umfassen. Beispielsweise kann zum Erfassen der Fahrzeugdaten eine Erkennung eines Anhängers und/oder einer Kopplung des Anhängers durchgeführt werden. Dadurch kann festgestellt werden, ob es sich bei dem Fahrzeug um ein Fahrzeug der vorbestimmten Fahrzeugart handelt. Ferner können die Fahrzeugdaten einen Richtungsparameter einer Fahrtrichtung des Fahrzeuges, einen Verlauf eines Lenkwinkels, eine Anzahl an Lenkmanövern, eine Anzahl an Koppelvorgängen eines Anhängers und/oder eine Geschwindigkeit des Fahrzeuges umfassen. Somit können die Fahrzeugdaten bei dem Parkvorgang die Stellflächenstruktur ergänzen, um z. B. die Zugänglichkeit der Stellfläche zu bewerten. Ferner ist es denkbar, dass die Umgebungsdaten anhand der Fahrzeugdaten insbesondere verifiziert und/oder plausibilisiert werden. Insbesondere wenn das Verfahren für viele Fahrzeuge einer Fahrzeugflotte durchgeführt wird, können der Ladeort und/oder mehrere Ladeorte anhand der Schwarmdaten mit einer hohen Genauigkeit beschrieben und/oder charakterisiert werden.Preferably, in a method according to the invention, it can be provided that the vehicle is assigned to the predetermined vehicle type, wherein the method, in particular in the form of a method step, comprises:

• - Recording of vehicle data during a parking process for parking the vehicle within the parking space structure, in particular by the control unit,

preferably, the vehicle data of the vehicle being taken into account when evaluating the parking space structure. The vehicle data can be recorded in particular to characterize the parking process. For example, the vehicle data can include information about a trailer. For example, a trailer and/or a trailer coupling can be detected to record the vehicle data. This makes it possible to determine whether the vehicle is a vehicle of the predetermined vehicle type. Furthermore, the vehicle data can include a direction parameter of a direction of travel of the vehicle, a course of a steering angle, a number of steering maneuvers, a number of coupling processes of a trailer and/or a speed of the vehicle. The vehicle data can thus supplement the parking space structure during the parking process, for example to Accessibility of the parking space is to be assessed. It is also conceivable that the environmental data are verified and/or checked for plausibility using the vehicle data. In particular, if the procedure is carried out for many vehicles in a vehicle fleet, the charging location and/or several charging locations can be described and/or characterized with a high degree of accuracy using the swarm data.

Furthermore, in a method according to the invention, it can advantageously be provided that a model, in particular a two-dimensional or three-dimensional model, of the parking space structure is generated and/or is provided when the suitability information is output with the suitability information for at least partially or completely automated execution of the parking process. During the parking process, the vehicle can be maneuvered onto the parking space and parked on the parking space in an at least partially automated manner. The model can be generated in particular when the parking space structure is determined. The model of the parking space structure can be part of an environmental model, in particular a virtual environmental world, of the vehicle. The model can be transmitted, for example, to a driver assistance system for carrying out the parking process. This allows the vehicle to carry out the parking process at least partially or completely autonomously using the model and/or the map. Based on the evaluation of the parking space structure, an available parking space at the loading location that is suitable for the type of vehicle can be selected automatically from several parking spaces during the parking process. In addition to the vehicle data, environmental data, such as weather data, can preferably be determined and taken into account when evaluating the parking space structure. For example, in the event of rain or slippery conditions, a sloping parking area may be unsuitable for the predetermined vehicle type and/or the automated parking process may need to be adjusted.

Furthermore, in a method according to the invention, it can advantageously be provided that a plausibility check of the assessment of the parking space structure is carried out, wherein a charging process of the vehicle is recorded during the plausibility check. It can thus be determined whether the vehicle is actually carrying out the charging process. For example, it can be provided that the suitability information is output depending on the plausibility check. The plausibility check can thus ensure that the parking space is suitable for charging the vehicle, in particular taking into account all real parameters, such as the length of a charging cable, a design of a charging plug, an occupancy of the parking space and the design of the parking space structure and its surroundings. For the plausibility check, it can be determined, in particular by trailer detection, whether the vehicle is assigned to the predetermined vehicle type.

Furthermore, in a method according to the invention, it can preferably be provided that several data sets of environmental data and/or vehicle data are obtained from different vehicles, in particular in the form of swarm data, whereby the data sets are merged and the evaluation of the parking space structure and/or the integration of the suitability information into the map takes place depending on the merged data sets. The data sets can thus form swarm data and/or be merged by a server. By merging the data sets, the environmental data and/or the vehicle data of the different vehicles can be updated and/or mutually verified. Furthermore, by merging the data sets, the accuracy of the evaluation of the parking space structure and/or the recognition of the parking option can be improved. For example, the different vehicles can have different vehicle and/or trailer lengths. As a result, the vehicle data of the respective parking process can be used to evaluate, for example, the parking space, the access area and/or the exit area for the respective vehicle and/or trailer length in order to recognize the parking option depending on the vehicle and/or trailer length.

According to a further aspect of the invention, a computer program product is provided. The computer program product comprises instructions which, when executed by a control unit, cause the control unit to carry out a method according to the invention.

Thus, a computer program product according to the invention brings with it the same advantages as have already been described in detail with reference to a method according to the invention. The method can in particular be a computer-implemented method. The computer program product can be implemented as computer-readable instruction code. Furthermore, the computer program product can be stored on a computer-readable storage medium such as a data disk, a removable drive, a volatile or non-volatile memory or a built-in memory/processor. Furthermore, the computer program product can be provided or made available in a network such as the Internet, from which it can be downloaded by a user or executed online if required. The computer program product can be implemented using software or one or more special electronic circuits, i.e. in hardware or in any hybrid form, i.e. using software components and hardware components.

According to a further aspect of the invention, a system is provided. The system has a vehicle and a control unit for carrying out a method according to the invention.

A system according to the invention thus brings with it the same advantages as have already been described in detail with reference to a method according to the invention and/or a computer program product according to the invention. The control unit can comprise artificial intelligence, in particular in the form of an artificial neural network, a processor and/or a microprocessor. Furthermore, the control unit can be at least partially or completely integrated into a server and/or into a control unit of the vehicle. However, it is also conceivable that the control unit is at least partially or completely distributed across a computer network. Preferably, the system has several vehicles, in particular of the predetermined vehicle type and/or different vehicle types, whereby swarm data can be collected by the method and used to improve the recognition of parking options. Furthermore, it can be provided that the charging unit is part of the system.

Further advantages, features and details of the invention emerge from the following description, in which embodiments of the invention are described in detail with reference to the drawings. The features mentioned in the claims and in the description can each be essential to the invention individually or in any combination. They show schematically:

• 1 a vehicle at a loading location when carrying out a method according to the invention,
• 2 the process in a schematic representation of process steps, and
• 3 a map displayed in the vehicle with several charging locations.

In the following description of some embodiments of the invention, the same reference numerals are used for the same technical features even in different embodiments.

1 shows a system 4 according to the invention with a vehicle 1 at a charging location 10 in a first exemplary embodiment. The charging location 10 comprises a charging unit 11 for providing electrical energy for the vehicle 1. The charging unit 11 can be formed, for example, by a charging station. The system 4 also has a control unit 2 for carrying out a method 100 according to the invention for providing information for recognizing a parking option for a predetermined type of vehicle in a charging infrastructure 3. The charging infrastructure 3 can, for example, comprise several charging locations 10 and/or several charging units 11. The predetermined type of vehicle here comprises, in particular exclusively, trailers. To carry out the method 100, a computer program product can be provided which comprises commands which, when executed by the control unit 2, cause the control unit 2 to carry out the method 100. In the present exemplary embodiment, the control unit 2 is integrated into a server 5. However, it is also conceivable that the control unit 2 is integrated locally into the vehicle 1.

As in 2 shown using a schematic breakdown of the method 100 into method steps, firstly, image-based environmental data 200 of a vehicle environment of a vehicle 1 at the charging location 10 is received 101. The image-based environmental data 200 can be recorded by an environmental sensor system of the vehicle 1, in particular in the form of a vehicle camera, and preferably at least partially processed. In addition, occupancy information 201 is recorded 101.1 about a current occupancy status of the charging unit 11. The occupancy information 201 can be received, for example, from an operator of the charging unit 11 and/or the charging location 10 through the vehicle 1 and/or the control unit 2. The occupancy information 201 includes in particular information as to whether the charging unit 11 is still available for charging. For example, the occupancy information 201 can include a number of available and/or occupied charging plugs of the charging unit 11.

On the basis of the environmental data 200, a parking space structure 13 of a parking space 12 for parking the vehicle 1 at the loading location 10 is also determined 102. When determining 102 the parking space structure 13, for example, a length 13.1 of the parking space 12 can be determined. Furthermore, a two-dimensional or three-dimensional model of the parking space structure 13 can preferably be generated.

Depending on the predetermined vehicle type, an evaluation 103 of the parking space structure 13 is also carried out to identify the parking possibility, in particular on the parking space 12, for the predetermined vehicle type. For example, a Accessibility of the parking space 12 can be assessed based on an access area 13.2 of the parking space 12 and/or an exit area 13.3 of the parking space 12 depending on the predetermined vehicle type. Furthermore, the occupancy information 201 can be compared with the environmental data 200, for example in order to verify a number of available charging plugs of the charging unit 11 based on an occupancy of the parking space 12.

Furthermore, in the method 100, at least one item of suitability information 210 regarding the parking possibility is output 104 depending on the evaluation 103 of the parking space structure 13. The suitability information 210 can be output directly externally by the server 5 and/or sent to a provision unit 5.1 for further processing.

The system 4 can advantageously comprise a plurality of vehicles 1. The suitability information 210 can inform the vehicles 1 whether the charging location 10 and/or the parking space 12 is suitable and/or available for charging. The output 104 of the suitability information 210 can be carried out in particular depending on the comparison of the occupancy information 201 and the environmental data 200. Furthermore, when outputting 104 the suitability information 210, the model can be provided with the suitability information 210 for at least partially or completely automated execution of a parking process 230 of the vehicle 1.

In particular, if the vehicle 1 is assigned to the predetermined vehicle type, i.e. in particular is itself of the predetermined vehicle type, the suitability information 210 can be output after the parking process 230 has been carried out. In this case, a recording 103.2 of vehicle data 203 of the vehicle 1 can be provided during the parking process 230 for parking the vehicle 1 within the parking space structure 13. The vehicle data 203 of the vehicle 1 can thus be taken into account when evaluating 103 the parking space structure 13 and make the evaluation plausible. Additionally or alternatively, a plausibility check 103.1 of the evaluation of the parking space structure 13 can be carried out by recording a charging process of the vehicle 1.

Thus, the loading location 10 can be characterized by the method 100 using the data of the vehicle 1 for the predetermined vehicle type. For example, to output 104 the suitability information 210, a location 202 of the loading unit 11 and, as in 3 shown, an integration of the suitability information 210 into a map 220, in particular for navigation of the vehicles 1, can be carried out. For this purpose, the map 220 can be displayed, for example, on a navigation device of the vehicles 1 when the suitability information 210 is output 104. For example, part of the charging infrastructure 3 or the entire charging infrastructure 3 can be displayed on the map 220. As a result, swarm data from the vehicles 1 can update and/or keep the map 220 up to date, in particular in real time, with regard to charging locations 10, in particular for the predetermined vehicle type, thereby achieving a high information density and/or information quality when finding charging options for charging the vehicles 1 of the predetermined vehicle type. Furthermore, it can be provided that in the method 100, several data sets of environmental data 200 and/or vehicle data 203 from different vehicles 1, which use the charging unit 11, for example one after the other, are obtained in the form of swarm data, in particular by the server 5. The data sets are merged by the server 5 so that the evaluation 103 of the parking space structure 13 and/or the integration of the suitability information 210 into the map 220 can take place depending on the merged data sets. This can achieve improved accuracy, timeliness and/or verification of the recognition of the parking option for outputting 104 of the suitability information 210.

The above explanation of the embodiments describes the present invention exclusively in the context of examples. Of course, individual features of the embodiments can be freely combined with one another, provided they are technically expedient, without departing from the scope of the present invention.
