Description

The invention relates to a method and a corresponding device that are designed to support a vehicle during a charging and/or refueling process at an energy station, e.g. at a gas station or at a charging station.

A vehicle typically has at least one energy store in which an energy carrier (e.g. a liquid or gaseous fuel or electrical energy) for the operation, in particular for the drive, of the vehicle can be stored. A certain quantity of the energy carrier can be supplied to the energy store via an energy interface (e.g. via a charging connection or via a filler or tank neck). For this purpose, a complementary energy interface (e.g. a charging plug or a nozzle or nozzle) of an energy station can be connected to the energy interface of the vehicle. The energy interface of the energy station is typically connected to the actual energy source (e.g. the electrical supply network or a fuel tank) via a (flexible) energy line (e.g. an electrical cable or a hose).

Different vehicles and/or different energy stations can have different properties that can affect the energy supply to the energy stores of the different vehicles. This can affect the comfort of using vehicles. The present document deals with the technical task of increasing the comfort of a vehicle in connection with the energy supply to the vehicle's energy store and/or increasing the reliability of energy supply processes of the vehicle.

The object is solved by each of the independent claims. Advantageous embodiments are described inter alia in the dependent claims. It is pointed out that additional features of a patent claim dependent on an independent patent claim without the features of the independent patent claim or only in combination with a subset of the features of the independent patent claim can form a separate invention independent of the combination of all features of the independent patent claim, which can be made the subject of an independent claim, a divisional application or a subsequent application. This applies equally to the technical teachings described in the description, which can form an invention independent of the features of the independent patent claims.

According to one aspect, a device for supporting an energy supply process of an energy store of a vehicle at an energy station is described, wherein the energy station is set up to provide an energy carrier. The device may be (at least partially or fully) part of the vehicle. Alternatively or additionally, the device (at least partially or completely) can be part of a vehicle-external server. An example energy storage device is an electrical energy storage device (e.g. a battery) or a fuel tank (e.g. for a liquid or a gaseous fuel). An exemplary energy station is a charging station (to provide electrical energy) or a gas station (to provide fuel). An example energy carrier is electrical energy or a liquid or gaseous fuel. An exemplary energy delivery process is a charging process or a refueling process.

The device is set up to determine geometry information relating to one or more geometric properties of an energy station. The geometry information can include and/or indicate: a dimensioning of the parking space of the energy station (for parking the vehicle during an energy supply process); an arrangement of the energy source (e.g. the charging station or the fuel pump) for providing the energy source relative to the parking space; a length of the line (e.g. the electric cable or the hose) for the transmission of the energy carrier from the energy source to the energy interface (e.g. to the charging plug or to the fuel nozzle) of the energy station; the pliability and/or the flexibility of the line for transmission of the energy carrier; and/or information relating to at least one object (a static object such as a wall or a dynamic object such as another vehicle) in the vicinity of the energy station, in particular information relating to an object adjacent to the parking space of the energy station.

The geometry information can thus indicate which one or more geometric restrictions exist with respect to an energy delivery process at the energy station. The geometry information can relate to two dimensions (2D), such as width and length information, or to three dimensions (3D), such as with additional height information.

The device is also set up to support an energy supply process of the energy store of the vehicle at the energy station on the basis of the geometry information determined. In this case, it can be determined, in particular on the basis of the geometric information, whether this is due to one or more geometric restrictions on the energy station an energy supply process of the vehicle at the energy station is possible at all. Alternatively or additionally, a positioning of the vehicle at the energy station can be determined, which enables the most comfortable and/or reliable energy supply process possible. Furthermore, the actual parking of the vehicle at the energy station and/or the actual coupling of the energy interfaces can be supported (eg by issuing a message to the user of the vehicle). By taking the geometry information into account, a comfortable and reliable energy supply process is thus made possible.

The vehicle and the energy station can each have an energy interface (e.g. a charging connection or a filler neck or a charging plug or a fuel nozzle) for the transmission of the energy source from the energy source of the energy station to the energy store of the vehicle.

The device can be set up to determine on the basis of the geometry information whether it is possible or not to carry out an energy supply process at the energy station due to the arrangement of the energy interface of the vehicle on the vehicle and due to the arrangement of the energy interface of the energy station on the energy source. A selection of one or more energy stations can thus be determined in a precise manner, which are actually possible for an energy supply process.

Alternatively or additionally, the device can be set up to determine, based on the geometric information, a positioning of the vehicle at the energy station for an energy supply process at the energy station, which enables the energy interface of the energy station to be coupled to the energy interface of the vehicle, in particular to be mechanically connected. In this way, the comfort and reliability of an energy supply process can be increased in a special way.

The device can thus be set up to determine at least one positioning of the vehicle at the energy station for an energy supply process at the energy station on the basis of the geometric information. It can then be arranged that the vehicle is parked at the energy station according to the determined positioning. In particular, the device can be set up to determine a driving route, starting from the current position of the vehicle to the energy station, depending on the determined positioning of the vehicle. Alternatively or additionally, the device can be set up to determine (and possibly output) one or more (acoustic and/or visual) indications in relation to how the vehicle should be parked at the energy station, depending on the determined positioning of the vehicle /or how the line for transferring the energy carrier from the energy station to the vehicle should be arranged. In this way, the user of the vehicle can be assisted in carrying out an energy supply process in a particularly convenient manner.

The device can be set up to determine vehicle information relating to the arrangement of the energy interface for the energy carrier on the vehicle. The energy interface can be arranged, for example, at the front, at the rear, on the driver's side and/or on the passenger side. The process of supplying energy from the vehicle's energy store at the energy station can then also be supported on the basis of the vehicle information determined. By taking vehicle information into account, the reliability and convenience of power supply operations can be further increased.

• • ob das Fahrzeug derart an der Energiestation abgestellt werden kann, dass weiterhin ein Zugang zu dem Fahrzeug oder aus dem Fahrzeug möglich ist.

The device can be set up to check one or more criteria on the basis of the geometry information. Exemplary criteria are:

• • whether the energy station parking space is large enough to park the vehicle;
• • whether the vehicle can be parked at the energy station in a predetermined orientation for the energy station;
• • whether the vehicle can be parked at the energy station in such a way that the line for transmitting the energy carrier can be arranged between the energy source of the energy station and the energy interface of the vehicle, and/or
• • whether the vehicle can be parked at the energy station in such a way that access to or from the vehicle is still possible.

Based on the one or more checked criteria, it can then be decided whether or not the energy station is suitable for an energy supply process of the vehicle.

The device can be set up to determine geometry information for a plurality of different energy stations. Furthermore, the device can be set up to determine, on the basis of the geometric information of the plurality of different energy stations, a list with one or more energy stations from the plurality of different energy stations at which the vehicle can be positioned in such a way that an energy supply process of the energy store of the vehicle is possible is. the A list with one or more energy stations can then be offered to the user for selection. The comfort of the user can be further increased in this way.

According to a further aspect, a (road) motor vehicle (in particular a passenger car or a truck or a bus or a motorcycle) is described which comprises the device described in this document.

According to a further aspect, a method for supporting an energy supply process of an energy store of a vehicle at an energy station is described. The method includes determining geometry information related to one or more geometric properties of the power station. The method also includes supporting an energy supply process of the vehicle's energy store at the energy station on the basis of the geometric information determined.

According to a further aspect, a software (SW) program is described. The SW program can be set up to be executed on a processor (e.g. on a vehicle's control unit) and thereby to carry out the method described in this document.

According to a further aspect, a storage medium is described. The storage medium can comprise a SW program which is set up to be executed on a processor and thereby to carry out the method described in this document.

1a shows exemplary components of a vehicle 100 that has an (electrical) energy store 104 for storing (electrical) energy for the operation, in particular for the drive, of the vehicle 100 . The energy store 104 can be charged via a charging connection 105 of the vehicle 100 .

The vehicle 100 can include a user interface 102 via which the user of the vehicle 100 can be shown a list of charging stations in the vicinity of the vehicle 100, for example (e.g. as part of a navigation system). Further, information related to a charging station may be provided to the user (such as the type of charging plug of the charging station and/or the possible charging power of the charging station). Information about a charging station can be provided, for example, by a central unit 110 (e.g. by a backend server) via a (wireless) communication link 106 and via a communication unit 103 of the vehicle 100 .

A (control) device 101 of the vehicle 100 can be set up to obtain the information about the one or more charging stations from the central unit 110 and to cause the information to be output via the user interface 102 of the vehicle 100 . Furthermore, it can Vehicle 100 are routed to a charging station selected by the user.

As in 1b shown by way of example, the charging connection 105 of the vehicle 100 can be arranged at different points of the vehicle 100 . For example, the charging port 105 may be located at the front, at the rear, or at a side (eg, driver's side or passenger's side) of the vehicle 100 .

Furthermore, as exemplified in 1c shown, a charging station 120 can be constructed differently. A charging station 120 can have, for example, one or more structural boundaries or objects 124 (eg a wall) at a parking space 123 for charging a vehicle 100 . In addition, parking space 123 may have one or more geometric properties (eg, width, length, area size, etc.). The charging column 121 (ie the energy source) of the charging station 120 can be arranged at different positions relative to the parking space 123 . In addition, the (charging) line 122 emanating from the charging station 121 can have a specific length.

A charging station 120 can thus have one or more geometric properties that have an influence on whether and possibly how a vehicle 100 can be charged at the charging station 120 . The one or more properties of a charging station 120 can be stored as geometric information relating to the charging station 120 in the central processing unit 110 and/or on a storage unit of the vehicle 100 and when selecting a suitable charging station 120 for a charging process and/or when performing it of a loading process are taken into account.

The (control) device 101 of the vehicle 100 can be set up to determine geometry information in relation to a charging station 120 . Furthermore, the device 101 can be set up to determine on the basis of the geometric information whether it is (geometrically) possible to carry out a charging process for the vehicle 100 at the charging station 120 . To this end, vehicle information relating to the location of the charging port 105 on the vehicle 100 may also be considered.

The device 101 can also be set up to determine an orientation of the vehicle 100 at the charging station 120 on the basis of the geometric information (and possibly on the basis of the vehicle information). The orientation of the vehicle 100 can be determined in order to enable the user of the vehicle 100 to connect the charging plug of the charging station 120 to the charging connection 105 of the vehicle 100 in a reliable and convenient manner.

2 shows on the left a vehicle 100 with a rear charging connection 105. For this vehicle 100 it can be determined that the vehicle 100 should be parked backwards on the parking space 123 in order to be able to connect the charging plug of the charging station 120 to the charging connection 105. The vehicle 100 on the right has a front charging port 105 and it can therefore be determined that the vehicle 100 should drive forward into the parking space 123 for charging.

3a shows a vehicle 100 with a lateral, rear charging connection 105, which was driven forward onto the parking space 123 of a charging station 120. The line 122 of the charging station 120 would be long enough to be routed along the right side of the vehicle 100 to connect the charging plug. However, a structural boundary 124 (eg a wall) is arranged on the right-hand side of vehicle 100 so that it is difficult or impossible for the user of vehicle 100 to place line 122 between boundary 124 and vehicle 100 . On the other hand, the line 122 is not long enough to route the line 122 past the left side of the vehicle 100 to the charging port 105 .

The device 101 of the vehicle 100 can be set up, based on the geometry information for the in 3a illustrated charging station 120 to determine that the vehicle 100 should be parked backwards in the parking space 123 (as in 3b shown) to enable a reliable and convenient charging process at the charging station 120.

4 shows an exemplary charging station 120 with two charging stations 123, which can be operated from a charging station 121. No charging process is possible for the vehicle 100 shown on the right-hand side, since the line 122 is too short to reach the front charging connection 105 of the vehicle 100 . Based on the geometric information about the charging station 120 and taking into account the vehicle information for the vehicle 100, it can be determined in advance that the vehicle 100 should be parked in the parking space 123 in such a way that the front of the vehicle 100 points in the direction of the charging station 121. This enables a convenient and reliable charging process.

The device 101 described in this document can thus be set up to implement one or more geometric framework conditions (ie Geometry information) must be taken into account when selecting charging options. Furthermore, a recommendation for action for the driver of a vehicle 100 or for an autonomous vehicle 100 can be derived. The measures described in this document can be carried out (in whole or in part) on different systems, e.g. in a vehicle 100, on a mobile device of a user of a vehicle 100 and/or on a backend server 110.

If a vehicle 100 is to be charged at a charging station 120, then the vehicle 100 must be connected to the charging station 120, in particular to the charging station 121, with a cable 122. Depending on how the vehicle 100 was parked relative to the charging station 120 or to one or more objects 124 in the vicinity of the charging station 120, this task may be impossible or made significantly more difficult. A suitable orientation or positioning of the vehicle 100 at the charging station 120 can be determined by taking into account geometric information in relation to the charging station 120 .

The geometry information for a charging station 120 can be retrieved from a database on a server 110, for example. The geometry information may be at least partially static and/or at least partially dynamic (and may be updated when changed).

• • What width is required to exit vehicle 100 (eg, based on door geometry)?

• • How many people are in vehicle 100 and, if so, where are they sitting?
• • Which one or more people are these (eg children who cannot get out themselves but have to be lifted out of the vehicle 100)?

  • ◯ es können in der ermittelten Position und/oder Orientierung des Fahrzeugs 100 alle Personen (bzw. eventuell nur der Fahrer) aus dem Fahrzeug 100 aussteigen bzw. es ist weiterhin der Zugang zu dem Fahrzeug 100 möglich.

A list of possible charging stations 120 can thus be provided, possibly based on a preselection. It can then be checked for all charging stations 120 from the list of possible charging stations 120 whether a vehicle position and/or vehicle orientation (ie a vehicle positioning) exists which, for example, meet all or part of the following criteria:

• • the vehicle 100 is within the limits of the parking space 123 of the charging station 120,
• • a possibly predetermined alignment of the vehicle 100 is maintained;
• • the cable 122 can be routed so that the vehicle 100 can be connected to the charging station 121, ie, for example

  • In the determined position and/or orientation of the vehicle 100, all persons (or possibly only the driver) can exit the vehicle 100 or access to the vehicle 100 is still possible.

A suitable vehicle position and/or vehicle orientation can be determined in different dimensions (in particular 2D or 3D). If necessary, different positions and/or orientations relative to the charging station 120 under consideration, relative to the parking space boundary and/or relative to a surrounding object 124 can be selected. At least one possible cable route between charging station 121 and charging connection 105 of vehicle 100 can then be determined for each position and/or orientation (i.e. for each considered positioning) of vehicle 100 . For example, a model for simulating flexible bodies can be used. Each (possibly random) vehicle position and/or vehicle orientation considered can then be evaluated based on the determined cable run and, if necessary, taking into account the above criteria.

If a specific termination criterion is met (e.g. maximum number of checked positions and/or orientations, identification of a possible position and/or orientation, maximum possible computing time), the search for a suitable position and/or orientation of vehicle 100 can be ended.

If no valid position and/or orientation of vehicle 100 can be determined for a charging station 120 , then this charging station 120 can be discarded from the list of possible charging stations 120 .

• • wie viele unterschiedliche valide Positionen und/oder Orientierungen gefunden wurden; und/oder
• • wie groß die Distanz zwischen Ladesäule 121 und Ladeanschluss 105 am Fahrzeug 100 ist.

The one or more charging stations 120, for which at least one valid position and/or orientation of the vehicle 100 can be determined for the respective charging station 120, can be offered to the user of the vehicle 100 in a list with one or more valid charging stations 120 for selection . The one or more valid charging stations 120 may be sorted based on one or more metrics, e.g. based on

• • how many different valid positions and/or orientations were found; and or
• • how large the distance between charging station 121 and charging connection 105 on vehicle 100 is.

The user can then select a charging station 120. The determined position and/or orientation of the vehicle 100 for the selected charging station 120 can then be used for route guidance to the selected charging station 120. For example, the route guidance can be selected such that the vehicle 100 arrives at the charging station 120 from a travel direction that requires as little maneuvering of the vehicle 100 as possible in order to park at the charging station 120 at the determined position and/or according to the determined orientation.

Furthermore, the driver of the vehicle 100 can be supported (e.g. by issuing one or more instructions) when parking at the charging station 120 and/or when connecting the charging cable 122 . The one or more cues may be provided graphically (e.g., an indication of how to park and/or how the wire 122 should be routed) and/or audibly.

The method 500 includes determining 501 geometry information relating to one or more geometric properties of the energy station 120. The geometry information can in particular show the position of the energy source 121, the length of the line 122 and/or the size of the parking space 123 of the energy station 120.

The method 500 further includes supporting 502 an energy supply process of the energy store 104 of the vehicle 100 at the energy station 120 on the basis of the ascertained geometry information. The geometry information can be used in particular to check whether (from a geometric point of view) an energy supply process at the energy station 120 is possible at all. Furthermore, a (as comfortable as possible) positioning (i.e. position and/or orientation) of the vehicle 100 at the energy station 120 can be determined. Furthermore, the actual parking of the vehicle 100 at the energy station 120 according to the determined positioning (through automated driving and/or through the output of a message) can be supported.

The measures described in this document can increase the convenience and/or the reliability of charging processes (of energy supply processes in general) of a vehicle 100 .

The present invention is not limited to the exemplary embodiments shown. In particular, it should be noted that the description and the figures are only intended to illustrate the principle of the proposed methods, devices and systems by way of example.
