Description

Method, computer program product and system for identifying a parking possibility of a vehicle
Technical Field
The invention relates to a method, a computer program product and a system with a vehicle for providing information for identifying a parking possibility of a predetermined vehicle type in a charging infrastructure.
Background
It is known to use sensor technology of a vehicle in order to assist a driver when driving to a charging site for charging an electric vehicle. It is known, for example, from GB 2500691B, to control a vehicle by means of sensor technology, by means of an inductive charging point and to orient the vehicle toward the charging point.
However, before the charging location can be controlled in this way, for an electrically or partially electrically operated vehicle, the parking space situation in front of a common or partially common charging station is an important factor for the success of the charging process. The charging of the vehicle may be completely hindered by an excessively narrow or short placement at the charging station. Furthermore, it is important for trailers with electric traction vehicles that there is sufficient position for the towed trailer without blocking other charging piles or having to unclamp the hitch during each common charging.
Disclosure of Invention
The object of the present invention is to at least partially eliminate the previous disadvantages known from the prior art. The object of the invention is, in particular, to improve the recognition, in particular the early recognition, of the possibility of parking a charging process for a predetermined vehicle type.
The object is achieved according to the invention by a method, a computer program product and a system for providing information for identifying a parking possibility of a predetermined vehicle type in a charging infrastructure. Other features and details of the invention are set forth in the description and drawings. The features and details described in connection with the method according to the invention are of course also applicable here in connection with the computer program product according to the invention and/or the system according to the invention and vice versa, respectively, so that the disclosures on the individual inventive aspects always relate to one another or can relate to one another.
According to a first aspect of the invention, a method for providing information to identify a parking possibility of a predetermined vehicle type in a charging infrastructure is specified. The method comprises, in particular in the form of method steps:
obtaining image-based ambient data of the vehicle's vehicle surroundings at a charging site of a charging unit for providing the vehicle with electrical energy, in particular by means of a control unit and/or an ambient sensing means of the vehicle,
determining, in particular by means of a control unit, a placement surface structure of a placement surface for parking the vehicle at the charging site from the ambient data,
evaluating the placement surface structure, in particular by the control unit, as a function of the predetermined vehicle type, in order to identify the possibility of parking in particular on the placement surface,
in particular, by the control unit, at least one suitability information for the parking possibility is output as a function of the evaluation of the placement surface structure.
The vehicle may in particular be a motor vehicle, preferably in the form of an electric vehicle. The predetermined vehicle type may preferably comprise a vehicle having a predetermined length, in particular a length of greater than or equal to 5m, preferably greater than or equal to 7 m. The predetermined vehicle type may for example comprise, preferably only, a trailer and/or a truck. The predetermined vehicle type can also be referred to as a predetermined vehicle class, among other things. The charging infrastructure may in particular be a local, regional and/or global charging infrastructure. The charging infrastructure may for example comprise the charging site with the charging unit and preferably comprise further charging sites and/or further charging units.
A charging location is understood to mean, in particular, a location at which a charging of a vehicle battery, in particular a traction battery, of a vehicle can take place. The charging point here comprises in particular a contact surface. The charging unit may comprise, for example, a common or non-common charging peg. The charging unit may, for example, have one or more charging plugs for connecting to the vehicle battery. The charging location may include a plurality of charging units.
Image-based ambient data can be understood in particular as sensor data which at least partially or completely comprise virtual and/or camera-based image data of the vehicle surroundings. It is conceivable here for the sensor data to be analyzed and/or processed locally at least in part or completely by a non-centralized control unit of the environmental sensor device. The image-based ambient data may comprise, inter alia, raw data and/or processed data of the ambient sensing device. The image-based ambient data can preferably be detected (or acquired) by an ambient sensor device and transmitted to the control unit. The environmental sensor device may be, for example, a camera of the vehicle, in particular a front camera.
Placement surfaceIn particular, a parking surface for parking the vehicle can be formed during the charging process. The placement surface structure may for example comprise boundaries of the placement surface, for example in the form of traffic lane markings and/or curbstones. Further, the placement surface structure may include a position of the charging unit with respect to the placement surface. In determining the placement surface structure, the ambient data may be analyzed, in particular by means of further sensor data and/or vehicle data, in order to identify, i.e. in particular extract, the placement surface structure from the ambient data.
In evaluating the placement surface structure to identify a parking possibility, it may be analyzed whether the placement surface is suitable for parking a predefined vehicle type. For example, the length and/or width of the placement surface may be compared to the dimensions of the vehicle type. Provision may be made for waiting and/or asking the driver and/or the charging customer of the charging unit for feedback when evaluating the placement surface structure in order to verify an automated evaluation.
The suitability information may comprise binary information, i.e. whether there is a parking possibility on the placement surface. However, it is equally conceivable that the suitability information comprises more complex information, such as evaluation information about the parking possibility, classification and/or ordering. For example, it can be provided that the parking possibilities can be arranged in a scale of the evaluation system as a function of the suitability information. The outputting of the suitability information may include displaying and/or transmitting the suitability information. For example, suitability information may be displayed on a display device for the driver of the vehicle and/or transmitted to a vehicle system of the vehicle and/or to other vehicles.
Thus, by means of the suitability information, information about the charging location can be provided, which here assists the driver of the predetermined vehicle type and/or the operating system in order to find a suitable charging location. By taking into account the image-based ambient data, the vehicle is not compliant with an indication of information that may be present by an operator of the charging unit. Furthermore, the suitability information can thus be based on the actual situation at the charging site and detect changes in the charging infrastructure and/or the charging site, for example, in real time. If the suitability information is provided, for example, to other vehicles when the suitability information is output, these other vehicles can determine in advance whether the charging location is available to them and drive to other charging locations if necessary. This has the further advantage for the driver of the vehicle that he does not need or only needs less experience in order to be able to estimate the possibility of parking at the charging site, whereby e.g. futile shunting can be avoided.
In the method according to the invention, it may furthermore be provided that the predetermined vehicle type comprises a trailer, preferably only a trailer, wherein the length of the placement surface is determined when determining the placement surface structure. The vehicle may in particular be a vehicle of a predetermined vehicle type, i.e. in particular a trailer. A trailer is understood to mean in particular a vehicle with a coupled trailer. Due to the trailer, the operability of shunting may be limited. Furthermore, some of the placement surfaces at the charging site may not have sufficient length for the trailer. It can be determined whether there is a parking possibility for the vehicle type based on the length of the placement surface. It is therefore particularly advantageous to evaluate the placement surface structure for the trailer and/or to output suitability information for the trailer.
In the method according to the invention, it can furthermore be provided that, in the evaluation of the surface structure, the accessibility of the surface is evaluated as a function of the entry area of the surface and/or the exit area of the surface, depending on the predetermined vehicle type. The accessibility may be taken into account when outputting the suitability information. The suitability information may include, for example, information about accessibility. It is also conceivable that, as a complement to the suitability information, the accessibility is output jointly with the suitability information. In particular, the entry area and/or the exit area can be identified based on the ambient data when determining the placement surface structure. The entry area is to be understood as, in particular, the area on the charging site through which the vehicle can travel onto the placement surface. The exit area is understood to be the area on the charging site through which the vehicle can leave the placement surface. In the evaluation of accessibility, it is preferably checked whether the entry area differs from the exit area and/or whether a vehicle of a predetermined vehicle type can be moved forward toward the placement surface and then leave. Furthermore, for the assessment of accessibility, for example, a necessary number of shunting operations and/or steering movements can be calculated for a predetermined vehicle type. Accessibility may thus form, inter alia, a criterion for evaluating the placement surface structure. Furthermore, by evaluating the accessibility, more complex information about the parking possibility can be provided by the output of the suitability information.
In the method according to the invention, it can preferably be provided that the method comprises, in particular in the form of method steps:
in particular by the control unit detecting occupancy information regarding the current occupancy state of the charging unit,
wherein preferably the occupancy information is calibrated with ambient data and the output of suitability information is performed in dependence of the occupancy information and the calibration. The occupancy information may include information about the current number of charging spaces, charging units and/or charging plugs available for charging and/or occupied at the charging site. Occupancy information is preferably obtained from a server. The operator of the charging unit may for example provide said occupancy information. For calibration purposes, it can be checked, based on the ambient data, whether there are any further vehicles on the placement surface and/or at the charging unit. The occupancy information can thus be verified and/or specified, in particular in real time. It is therefore conceivable for the charging unit to have three or more different charging plugs, but only two placement surfaces. In this case, it may be the case that the operator's occupancy information indicates that there is a charging plug available, but that it is determined that both placement surfaces are occupied when the occupancy information is calibrated to the ambient data, i.e., that there is no parking possibility in particular. Thus, the combination of ambient data and occupancy information may enable a higher accuracy and/or complexity of the estimation of the occupancy situation at the charging unit.
In addition, in the method according to the invention, it is conceivable to realize the positioning of the charging unit and the integration of the suitability information in the map when outputting the suitability information. The positioning of the charging unit can be effected, for example, on the basis of geographical position data of the charging unit and/or of the vehicle, for example in the form of GPS data and/or galileo data. The map may in particular be a virtual map, in particular for navigation. The map may be provided, for example, based on geographic data. The map may be two-dimensional or three-dimensional. Further, the map may include map data, road data, topography data, traffic data, and/or road data for a plurality of charging sites. The map can in particular be updated continuously. Here, the suitability information may be entered in the form of metadata of the charging location as a function of the positioning of the charging unit. Preferably, the map can be provided to the other vehicles in particular in real time. Thus, the suitability information may be output as part of the cluster data. In particular, the method can be used to improve the map using cluster data of a plurality of vehicles and thus to achieve simplified navigation to a suitable charging location for a vehicle of a predetermined vehicle type. Furthermore, the integration of the suitability information in the map can enable and/or improve an automated parking process, for example on a parking space, for a predetermined vehicle type.
In the method according to the invention, it may be provided that the vehicle is associated with a predetermined vehicle type, wherein the method comprises, in particular in the form of method steps:
during parking for parking the vehicle in the parking surface structure, in particular by the control unit detecting vehicle data of the vehicle,
wherein preferably vehicle data of the vehicle are taken into account when evaluating the placement surface structure. The vehicle data can be used in particular to characterize the parking process. The vehicle data may include, for example, information about the trailer. For detecting vehicle data, for example, the identification of the trailer and/or the coupling of the trailer may be performed. It is thereby possible to determine whether the vehicle is a vehicle of a predetermined vehicle type. Furthermore, the vehicle data may include a direction parameter of the driving direction of the vehicle, a profile of the steering angle, a number of steering maneuvers, a number of coupling processes of the trailer and/or a speed of the vehicle. The vehicle data can thus supplement the placement surface structure during parking, for example, in order to evaluate the accessibility of the placement surface. Furthermore, it is conceivable to verify, in particular, the plausibility of the surrounding data and/or to check the plausibility of the surrounding data on the basis of the vehicle data. In particular, when the method is performed for a plurality of vehicles of a fleet, the charging location and/or a plurality of charging locations can be described and/or characterized with high accuracy based on the cluster data.
In addition, in the method according to the invention, it may be advantageously provided that a particularly two-dimensional or three-dimensional model of the placement surface structure is generated and/or that the model is provided together with suitability information when the suitability information is output in order to perform the parking process at least partially or completely automatically. During parking, the vehicle can be moved onto the parking surface and parked on the parking surface in a motorized manner at least in part automatically. The model may be generated in particular when determining the placement surface structure. The model of the placement surface may be a model of the surroundings of the vehicle, in particular a part of the virtual surroundings world. The model may be transmitted, for example, to a driving assistance system in order to implement a parking process. The vehicle may thus perform the parking process at least partially or completely autonomously in accordance with the model and/or map. Depending on the evaluation of the surface structure, it is possible, in particular during parking, to automatically select a surface available from a plurality of surfaces at the charging site and suitable for the vehicle type. As a supplement to the vehicle data, it is preferably possible to determine ecological environment data, for example weather data, and to take this into account when evaluating the placement surface structure. For example, in the event of rain or slippery conditions, an inclined placement surface may be unsuitable for a predetermined vehicle type and/or an automated parking process may be adjusted.
In addition, in the method according to the invention, it can be advantageously provided that a plausibility check (plausibility check) of the evaluation of the placement surface structure is carried out, wherein in the plausibility check the charging process of the vehicle is detected. It can thus be determined whether the vehicle actually carries out the charging process. For example, it may be provided that the suitability information is output in accordance with a plausibility check. It can thus be ensured by the plausibility check that the placement surface is suitable for charging the vehicle, in particular taking into account all the parameters that are actually present, such as the length of the charging cable, the design of the charging plug, the occupation of the placement surface and the design of the placement surface structure and the surroundings of the placement surface structure. In order to achieve a plausibility check, it can be determined, in particular, by means of a trailer identification, whether the vehicle is assigned to a predetermined vehicle type.
In the method according to the invention, it can furthermore be provided that a plurality of data sets, in particular in the form of cluster data, of the respective different vehicle surroundings data and/or vehicle data are obtained, wherein the data sets are fused and an evaluation of the placement surface structure and/or an integration of the suitability information in the map is carried out as a function of the fused data sets. Thus, the data sets may form clustered data and/or be fused by a server. By fusing the data sets, the surrounding data and/or the vehicle data of the different vehicles can be updated and/or verified with respect to each other. Furthermore, the accuracy of the evaluation of the placement surface structure and/or the recognition of the parking possibility can be improved by the fusion of the data sets. Different vehicles may have different vehicle lengths and/or trailer lengths, for example. The placement surface, the entry area and/or the exit area can thus be evaluated on the basis of vehicle data of the respective parking process, for example for the respective vehicle length and/or trailer length, in order to identify the parking possibility on the basis of the vehicle length and/or trailer length.
According to other aspects 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 implement the method according to the invention.
The computer program product according to the invention thus forms the same advantages as already described in detail in relation to the method according to the invention. The method may in particular be a computer-implemented method. The computer program product may be embodied as computer readable instruction code. Furthermore, the computer program product may be stored on a computer readable storage medium such as a data disk, a replaceable drive, a volatile or non-volatile memory or a built-in memory/processor. Furthermore, the computer program product may be provided or provided in a network, such as the internet, from which it may be downloaded by a user or implemented online, if desired. The computer program product can be realized both by means of software and by means of one or more special circuits, i.e. in hardware, or in any hybrid form, i.e. by means of software components and hardware components.

Furthermore, the control unit may be at least partially or completely integrated in the server and/or in the control device of the vehicle. However, it is equally conceivable that the control units are distributed at least partially or completely over the computer network. The system preferably has a plurality of vehicles, in particular a plurality of vehicles of a predetermined vehicle type and/or of different vehicle types, whereby cluster data can be lifted by the method and used to improve the recognition of the parking possibility. Furthermore, it may be provided that the charging unit is part of the system.

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.
Detailed Description
Fig. 1 shows in a first embodiment a system 4 according to the invention with a vehicle 1 at a charging site 10. The charging site 10 comprises a charging unit 11 for providing the vehicle 1 with electrical energy. The charging unit 11 may be formed by a charging pile, for example. Furthermore, the system 4 has a control unit 2 for implementing the method 100 according to the invention for providing information for identifying the parking possibility of a predetermined vehicle type in the charging infrastructure 3. The charging infrastructure 3 may for example comprise a plurality of charging sites 10 and/or a plurality of charging units 11. In this case, the predetermined vehicle type includes, in particular, only the trailer. For implementing the method 100, a computer program product may be provided, comprising instructions which, when executed by the control unit 2, cause the control unit 2 to implement the method 100. The control unit 2 is integrated in the server 5 in the present embodiment. However, it is also conceivable for the control unit 2 to be integrated locally in the vehicle 1.
As shown in fig. 2 in the method steps according to the schematic division of the method 100, image-based surroundings data 200 of the vehicle surroundings of the vehicle 1 at the charging site 10 are first obtained 101. The image-based ambient data 200 is detected by an ambient sensor device of the vehicle, in particular in the form of a vehicle camera, and is preferably processed at least in part. Occupancy information 201 about the current occupancy state of the charging unit 11 is additionally detected 101.1. The occupancy information 201 may be obtained, for example, by the vehicle 1 and/or the control unit 2 from the charging unit 11 and/or the operator of the charging site 10. The occupancy information 201 includes, in particular, information whether the charging unit 11 is also able to be used for charging. The occupancy information 201 may for example comprise the number of charging plugs of the charging unit 11 that are available and/or occupied.
Furthermore, a placement surface structure 13 for parking the placement surface 12 of the vehicle 1 at the charging site 10 is determined 102 from the ambient data 200. In determining 102 the placement surface structure 13, for example, the length 13.1 of the placement surface 12 can be determined. Furthermore, a two-dimensional or three-dimensional model of the placement surface structure 13 can preferably be generated.
Furthermore, the placement surface structure 13 is evaluated 103 as a function of the predetermined vehicle type in order to identify a parking possibility for the predetermined vehicle type, in particular on the placement surface 12. The accessibility of the placement surface 12 can be assessed here, for example, according to a predetermined vehicle type, as a function of the entry area 13.2 of the placement surface 12 and/or the exit area 13.3 of the placement surface 12. The occupancy information 201 can furthermore be calibrated with the ambient data 200 in order to verify the number of available charging plugs of the charging unit 11, for example, as a function of the occupancy of the placement surface 12.
Furthermore, in the method 100, at least one suitability information 210 for the parking possibility is output 104 as a function of the evaluation 103 of the placement surface structure 13. The output of the suitability information 210 may be implemented directly externally by the server 5 and/or sent to the providing unit 5.1 for further processing.
The system 4 may advantageously comprise a plurality of vehicles 1. The suitability information 210 may inform the vehicle 1 whether the charging site 10 and/or the placement surface 12 are suitable and/or available for charging. The output 104 of the suitability information 210 may be realized in particular from a calibration of the occupancy information 210 with the ambient data 200. Furthermore, the model may be provided together with the suitability information 210 when outputting 104 the suitability information 210 in order to perform the parking process 230 of the vehicle 1 at least partially or fully automatically.
The suitability information 210 may be output after the parking process 230 has been carried out, in particular if the vehicle 1 is assigned to a predetermined vehicle type, i.e. in particular is itself of the predetermined vehicle type. It may be provided that the vehicle data 203 of the vehicle 1 are detected 103.2 during a parking process 230 for parking the vehicle 1 in the parking surface structure 13. It is thereby possible to take into account the vehicle data 203 of the vehicle 1 when evaluating 103 the placement surface structure 13 and to check the plausibility of the evaluation. Alternatively or additionally, a plausibility check 103.1 of the evaluation of the placement surface structure 13 can be performed by detecting a charging process of the vehicle 1.
The charging site 10 can thus be characterized by the method 100 for a predetermined vehicle type using the data of the vehicle 1. For outputting 104 the suitability information 210, for example, the positioning 202 of the charging unit 11 can be carried out, and as shown in fig. 3, the integration of the suitability information 210 in the map 220, in particular for the navigation of the vehicle 1, is carried out. To this end, the map 220 may be displayed, for example, on a navigation device of the vehicle 1 when outputting 104 the suitability information 210. A part of the charging infrastructure 3 or the entire charging infrastructure 3 may be displayed on the map 220, for example. The cluster data of the vehicle 1 can thus update the map 220, in particular in real time, with respect to the charging location 10, in particular for a predetermined vehicle type, and/or keep the map 220 in the current state, whereby a higher information density and/or information quality is achieved when a charging possibility for charging the vehicle 1 of the predetermined vehicle type is found. It can furthermore be provided for this purpose that in the method 100, in particular via the server 5, several data sets in the form of cluster data of the respective different ambient data 200 and/or vehicle data 203 of the vehicle 1, which in turn use the charging unit 11, for example. The data sets are fused by the server 5, so that the evaluation 103 of the placement surface structure 13 and/or the integration of the suitability information 210 in the map 220 can be carried out from the fused data sets. Improved accuracy, current (i.e., real-time) and/or verification of the suitability information 210 for identifying parking possibilities for output 104 may thereby be achieved.
The foregoing description of the embodiments describes the invention in terms of examples only. Individual features of the embodiments can of course be freely combined with one another as long as they are technically reasonable, without leaving the scope of the invention.
