Description

Technical Field

[0001] The invention relates to a method for authenticating a vehicle at a charging station. The invention also relates to a computer-readable medium for authenticating a vehicle at a charging station, a system for authenticating a vehicle at a charging station and a vehicle comprising the system for authenticating a vehicle at a charging station. Background Art

[0002] It is known from the prior art that a plurality of contract certificates are stored in a vehicle, which enable charging of the vehicle at a charging station. Before charging at a charging station is possible, a contract certificate must be manually selected by the user. Summary of the invention

[0003] The object of the present invention is therefore to improve the authentication of a vehicle at a charging station in an efficient manner. In particular, the object of the present invention is to efficiently provide a contract certificate for authenticating the vehicle from the vehicle to the charging station.

[0004] This object is achieved by the features of the independent claim. Advantageous embodiments and developments of the invention are disclosed in the dependent claims.

[0005] According to a first aspect, the invention is characterized by a method for authenticating a vehicle at a charging station. The method can be a computer-implemented method and / or a control device-implemented method. The vehicle can be a motor vehicle, in particular a battery electric motor vehicle or a plug-in hybrid electric motor vehicle. The method comprises: determining a position of the vehicle. Furthermore, the method comprises: determining a contract certificate from a plurality of contract certificates of the vehicle based on the position of the vehicle. The method provides the contract certificate to the charging station via the vehicle. Finally, the method comprises: authenticating the vehicle at the charging station using the provided contract certificate.

[0006] Advantageously, the method can effectively determine the contract certificate used to authenticate the vehicle at the charging station. By automatically determining a single contract certificate, the authentication of the vehicle at the charging station can be effectively automated. For the user of the vehicle, the charging process at the charging station is effectively simplified. For the user of the vehicle, the manual determination of the contract certificate can be eliminated.

[0007] According to an advantageous embodiment, the contract certificate may be an encrypted contract certificate according to the Plug-and-Charge Standard. For example, the contract certificate may be a contract certificate according to the ISO 15118 Standard. The ISO 15118 Standard standardizes the Plug-and-Charge Function between a vehicle (in particular an electric vehicle) and a charging station. The method may effectively determine a standardized contract certificate and thereby effectively simplify the standardized authentication of vehicles at charging stations.

[0008] According to another advantageous embodiment, the method may further include: determining a user profile of the vehicle driver, and determining a contract certificate from a plurality of contract certificates of the vehicle based on the position of the vehicle and the user profile of the vehicle driver. Thus, the contract certificate can be efficiently determined by the vehicle.

[0009] According to another advantageous embodiment, the user profile may include a user-specific first preference value related to the properties of the contract certificate, and the contract certificate is determined by means of the user-specific first preference value of the user profile related to the properties of the contract certificate. The contract certificate can thus be determined efficiently.

[0010] According to another advantageous embodiment, the method may further include determining a user-specific charging profile of the vehicle and determining a contract certificate from a plurality of contract certificates of the vehicle based on the location of the vehicle, the user profile of the vehicle driver and the user-specific charging profile of the vehicle. The contract certificate may thus be determined efficiently.

[0011] According to another advantageous design, determining the contract certificate from a plurality of contract certificates of the vehicle based on the location of the vehicle may include: checking whether at least one contract certificate related to the location has been determined from a plurality of contract certificates of the vehicle based on the location of the vehicle. If no contract certificate has been determined based on the location of the vehicle, the method may load a new contract certificate from a server external to the vehicle to the vehicle, wherein the new contract certificate is a contract certificate that can be used to authenticate the vehicle at the charging station. In addition, the method may store the new contract certificate on the vehicle and determine the new contract certificate as the contract certificate for authenticating the vehicle at the charging station. In this way, the contract certificate can be dynamically determined for the authentication of the vehicle at the charging station.

[0012] According to another advantageous embodiment, determining a contract certificate from a plurality of contract certificates of the vehicle based on the location of the vehicle may include: determining a user-specific filter parameter and / or a vehicle-specific filter parameter, filtering the contract certificates from the plurality of contract certificates using the user-specific filter parameter and / or the vehicle-specific filter parameter to determine a single contract certificate from the plurality of contract certificates, and determining the single contract certificate as the contract certificate if more than one contract certificate is determined from the plurality of contract certificates based on the location of the vehicle. This effectively ensures that a single contract certificate is determined for the authentication of the vehicle at the charging station.

[0013] According to another aspect, the vehicle features a computer-readable medium for authenticating the vehicle at a charging station, wherein the computer-readable medium comprises instructions which, when executed on a computer or a control device, perform the method described above.

[0014] According to a further aspect, the invention features a system for authenticating a vehicle at a charging station, wherein the system is designed to carry out the method described above.

[0015] According to another aspect, the invention features a vehicle that includes the system described above for authenticating a vehicle at a charging station.

[0016] Further features of the invention are apparent from the claims, the drawings and the description of the drawings. All features and feature combinations mentioned above in the description and the features and feature combinations mentioned below in the description of the drawings and / or shown individually in the drawings can be used not only in the respectively indicated combination but also in other combinations or alone. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In the following, preferred embodiments of the present invention are described with the aid of the accompanying drawings. Further details, preferred embodiments and extensions of the present invention are obtained from this.

[0018] Figure 1 An exemplary method for authenticating a vehicle at a charging station is shown. DETAILED DESCRIPTION

[0019] Figure 1An exemplary method 100 for authenticating a vehicle at a charging station is shown in detail. A plurality of contract certificates can be stored on the vehicle, with which the vehicle can be authenticated at the charging station. The plurality of contract certificates can include, for example, 1, 2, 3, 4, ... 10, 11 ... 20 contract certificates. To authenticate the vehicle, exactly one contract certificate must be determined from the plurality of contract certificates, with which the vehicle is authenticated at the charging station before the charging process. The method 100 enables the automatic determination of exactly one contract certificate from the plurality of contract certificates, which the vehicle uses to authenticate the vehicle at the charging station.

[0020] The method 100 may determine 102 a location of the vehicle. The location of the vehicle may be a parking location of the vehicle at the charging station. For example, the parking location of the vehicle may be a parking location on private property. For example, the parking location of the vehicle may be in a public, open parking area. For example, the parking location of the vehicle may be a public or non-public parking garage. The location of the vehicle may be a current location of the vehicle during travel to the charging station. For example, if the vehicle is closer to the location of the charging station than a predetermined distance, the location of the vehicle may be determined.

[0021] The method 100 may determine 104 a contract certificate from a plurality of contract certificates of the vehicle based on the location of the vehicle. For example, a contract certificate may be associated with a location. If the location of the vehicle is at or near the location, the method may determine a contract certificate from the plurality of contract certificates, wherein the location of the vehicle and the location associated with the contract certificate coincide.

[0022] The method 100 may additionally determine a user profile of the vehicle driver and determine a contract certificate from a plurality of contract certificates of the vehicle based on the location of the vehicle and the user profile of the vehicle driver. The user profile of the vehicle driver is preferably stored on the vehicle. The user profile includes a user-specific first preference value related to an attribute of the contract certificate. The contract certificate may be determined by means of a user-specific first preference value of the user profile related to an attribute of the contract certificate. The user-specific first preference value may specify a user-specific priority of one or more contract certificates. The user-specific priority may, for example, specify a priority value for each contract certificate and / or for each attribute of the contract certificate. The priority value may be different based on the location. The method may determine the contract certificate with the highest priority value based on the location from a plurality of contract certificates as the contract certificate used by the vehicle for authentication at the charging station. The user profile may include other user-specific preferences. For example, the user profile may include one or more rules, which specify one or more user-specific preferences related to the contract certificates stored in the vehicle. The method may execute one or more rules to determine a contract certificate from a plurality of contract certificates.

[0023] The method 100 may further additionally determine a user-specific charging profile for the vehicle. The user-specific charging profile for the vehicle may be determined location-based based on the location of the vehicle. Additionally or alternatively, the user-specific charging profile for the vehicle may be determined time-based. The method may determine a contract certificate from a plurality of contract certificates for the vehicle based on the location of the vehicle, a user profile of the driver of the vehicle, and a user-specific charging profile for the vehicle. The user-specific charging profile may include location-based settings for configurable charging parameters, such as a maximum AC charging current, a maximum DC charging current, and / or a charging time. The method may additionally or alternatively use location-based settings for configurable charging parameters in order to determine a contract certificate from a plurality of contract certificates that the vehicle uses to authenticate at a charging station based on location.

[0024] If none of the contract certificates stored on the vehicle is suitable for authenticating the vehicle at the charging station, that is, no contract certificate can be determined based on the location of the vehicle, no contract certificate meets one or more preference values ​​of the driver's user profile, and / or no contract certificate satisfies the user-specific charging settings, the method can load a new contract certificate from a server external to the vehicle onto the vehicle. The new contract certificate is preferably a contract certificate that can be used to authenticate the vehicle at the charging station. Additionally, the new contract certificate can meet one or more preference values ​​of the driver's user profile and / or the user-specific charging settings. The new contract certificate can be stored on the vehicle and determined as the contract certificate for authenticating the vehicle at the charging station.

[0025] In the case where a plurality of contract certificates stored on the vehicle are suitable for authenticating the vehicle according to the position of the vehicle at the charging station, the vehicle can determine one or more user-specific filter parameters and / or one or more vehicle-specific filter parameters as described above in order to filter the plurality of contract certificates stored on the vehicle. For example, as user-specific and / or vehicle-specific filter parameters, one or more preference values ​​of the driver's user profile and / or one or more charging parameters of the charging profile can be used. The filter parameters can be applied in sequence to determine a single contract certificate as the contract certificate used by the vehicle for authentication at the charging station. If filtering using the filter parameters mentioned above results in more than one contract certificate being available for authentication of the vehicle, the method can provide the filtered contract certificates to the vehicle driver. For example, the filtered contract certificates can be displayed to the driver on a display (e.g., on a farewell screen of a display device of the vehicle) when the vehicle is parked. The driver can determine one of the filtered contract certificates with which the vehicle is authenticated at the charging station.

[0026] Additionally or alternatively, the method may determine the contract certificate based on the travel destination. For example, if the travel destination is the driver's workplace, a contract certificate associated with the driver's workplace may be determined. For example, if the driver's vehicle is an official vehicle, a contract certificate associated with the vehicle type of official vehicle may be determined. Additionally or alternatively, the travel destination and the vehicle type may be combined to determine the contract certificate. If the travel destination is the workplace and the vehicle type is an official vehicle, a contract certificate may be determined with which the vehicle may be authenticated as an official vehicle at the workplace.

[0027] The method 100 may include providing 106 the determined contract certificate by the vehicle at the charging station. The providing 106 may, for example, include transmitting the contract certificate from the vehicle to the charging station via a wireless communication interface. Finally, the method 100 may include authenticating 108 the vehicle at the charging station using the provided contract certificate. Authentication 108 of the vehicle at the charging station using the contract certificate may be performed automatically. For example, the vehicle may be automatically authenticated at the charging station using a contract certificate according to the ISO 15118 standard (also commonly referred to as the Plug-and-Charge-Standard).

[0028] Advantageously, the method may effectively and automatically determine a single contract certificate and thereby automatically authenticate the vehicle at the charging station. Reference numerals list
