Method and apparatus for determining a user profile of a vehicle on the basis of one or more key devices

1 . An apparatus for determining a user profile for the operation of a vehicle, the apparatus comprising:

a controller configured to:

determine that:

there is a communication connection to exactly one key device, and

there are respective communication connections to a plurality of key devices,

wherein each key device respectively has a digital key for authenticating the respective key device at the vehicle,

based on determining there is the communication connection to exactly one key device, automatically adopt a user profile for the operation of the vehicle, and

based on determining that there are respective communication connections to a plurality of key devices, have a user of the vehicle select a user profile from a set of different user profiles.

2 . The apparatus of claim 1 , wherein the controller is further configured to:

based on determining there are the communication connections to a plurality of key devices, determine, for the individual key devices, a respective user profile associated with the respective key device in order to determine the set of user profiles.

3 . The apparatus of claim 1 , wherein the controller is further configured to:

display the set of user profiles in the form of a list via a user interface,

capture a selection of one of the user profiles from the list of user profiles via the user interface, and

operate the vehicle with the selected user profile.

4 . The apparatus of claim 1 , wherein the controller is further configured to, based on determining there are the communication connections to a plurality of key devices:

determine, for the individual key devices, a respective distance between the respective key device and a reference position, in particular a driver's position, of the vehicle, and

have the user of the vehicle select a user profile from the set of different user profiles, wherein the selection made depends on the distances between the individual key devices and the reference position.

5 . The apparatus of claim 4 ,

wherein the different user profiles are associated with different key devices,

wherein the apparatus is configured to output, in particular display, the set of user profiles in the form of a list via a user interface, and

wherein the individual user profiles within the list are sorted on the basis of the distance between the key device associated with the respective user profile and the reference position, in particular such that the user profile associated with the key device that is at the relatively shortest distance is arranged at the top of the list.

6 . The apparatus of claim 1 ,

wherein the vehicle comprises a plurality of different zones, in particular seating positions, which can each be adjusted in a user-specific manner by a user profile, and

wherein the controller is further configured to:

determine position information relating to a position of the key device within the vehicle by means of the communication connection to a key device,

select exactly one of the different zones on the basis of the position information, and

adjust the selected zone in a user-specific manner according to a user profile associated with the key device.

7 . The apparatus of claim 1 , wherein a user profile comprises:

one or more user-specific settings for a vehicle seat,

one or more user-specific settings for an air conditioning system and/or a seat heating system,

one or more user-specific settings for an infotainment system, and/or

one or more user-specific settings for illumination of the vehicle.

8 . The apparatus of claim 1 , wherein the controller is further configured to:

receive and verify the digital key of a key device,

set up a communication connection, in particular an authenticated communication connection, to the key device when the digital key of the key device has been successfully verified, and

prevent a communication connection, in particular an authenticated communication connection, to the key device when the digital key of the key device has not been successfully verified.

9 . The apparatus of claim 1 ,

wherein the communication connections to the one or more key devices each include a Bluetooth Low Energy, BLE, and/or an Ultra-wideband, UWB, communication connection, and/or

wherein the digital key is designed in accordance with a Car Connectivity Consortium, CCC, key standard, in particular in accordance with CCC Release 3.

10 . A method for operating a vehicle, comprising:

determining that:

there is a communication connection to exactly one key device, and

there are communication connections to a plurality of key devices,

wherein each key device respectively has a digital key for authenticating the respective key device at the vehicle;

based on determining that there is the communication connection to exactly one key device, automatically adopting a user profile for the operation of the vehicle; and

based on determining that there are respective communication connections to a plurality of key devices, having a user of the vehicle select a user profile from a set of different user profiles.
