[0003] Digital vehicle key with user information

[0004] The present invention relates to a method for displaying user information to a user of a vehicle, in particular a welcome message or other user information is provided, which is displayed to the user especially when first approaching the vehicle.

[0005] In current technology, it is already possible for a vehicle owner or a key control authority, such as a fleet management company, to provide a digital vehicle key for use by a user.

[0006] This digital vehicle key is a digital vehicle key, a so-called friend key, logically and / or cryptographically linked to a key of the key control instance. The digital vehicle key can be stored on the user's mobile device, allowing them to open and start the vehicle without a physical key.

[0007] For this purpose, a so-called authentication or attestation information ("Attestation Package") is transmitted from a server system of the vehicle manufacturer to the user's mobile device. This attestation information is then transmitted to the vehicle upon the first radio contact between the mobile device and the vehicle in order to authenticate the user to the vehicle.

[0008] Furthermore, it is also known that the vehicle can display a welcome animation, for example by activating the headlights or projecting an interactive pattern onto the ground.

[0009] Especially in a fleet context, where frequently changing or temporary usage rights are granted to users through the provision of digital vehicle keys, there is a need to display user information, e.g., as personalized user information, particularly upon first approaching the vehicle. -2683 DE

[0011] The invention provides a solution according to the independent claims. Further developments of the invention are the subject of the dependent claims.

[0012] In a first aspect, a method for displaying user information to a vehicle user is provided, wherein a key control instance provides data for the user information as an addition to a digital vehicle key for the vehicle user to a mobile device, wherein the mobile device performs an authentication with the vehicle, in which the mobile device transmits an attestation information which includes the user information to the vehicle, the vehicle extracts the user information from the attestation information, and the vehicle displays the user information.

[0013] The user information can be a welcome message.

[0014] User information can be projected using a projector in the vehicle.

[0015] User information can be displayed via a vehicle display, in particular via an externally visible display.

[0016] The user information can include media content, in particular at least one text, one image, one video and / or music.

[0017] The user information may include a machine-readable code, in particular a QR code.

[0018] User information can be displayed on the vehicle user's mobile device, especially once they receive the digital key.

[0019] In another aspect, a system for displaying user information to a vehicle user is provided, with a key control instance set up to store data for user information as an addition to a -2683 DE

[0021] to provide a digital vehicle key to a mobile device, wherein the mobile device is configured to perform authentication with a vehicle and to transmit attestation information containing the user information to the vehicle, and wherein the vehicle is configured to extract the user information from the attestation information and to display the user information.

[0022] User information can be, for example, a personalized welcome message and may include a text message, an image, a video, and / or music. It could also be a guide or instruction on how to use the vehicle, which is particularly helpful for vehicles with new types of door handles or other technical features. User information can also include instructions on how to start the vehicle, for example, in vehicles that lack a traditional ignition lock or a start / stop switch.

[0023] When issuing the linked digital vehicle key or Friend Key to the user, the issuer of the vehicle key, in particular the key control instance, can additionally record user information, which is then included in the attestation information, for example, by the vehicle manufacturer's server system. The attestation information is transmitted to the user's mobile device. Upon the mobile device's first approach to the vehicle, it can transmit the attestation package for authentication, including the user information it contains, via wireless communication, such as UWB, Bluetooth, BLE, WLAN, and / or NFC. The vehicle extracts this user information and then displays it to the user, for example, by projecting it onto the ground or displaying it on a vehicle display unit. An audio output unit, such as the vehicle's sound system, can be used to play audio content. -2683 DE

[0025] The invention is now also described with regard to the figures. They show:

[0026] Fig. 1 schematically represents the procedure for transmitting and displaying user information.

[0027] Fig. 2 schematically shows the system for transmitting and displaying user information.

[0028] Figure 1 illustrates the procedure for displaying user information. The procedure for displaying user information to a vehicle user comprises the following steps:

[0029] In a first step, a key control instance provides S10 data for user information as an addition to a digital vehicle key (Friend Key) for the vehicle user, for example, via a server system ("backend") of the vehicle manufacturer. The digital vehicle key is then transmitted to the vehicle user's mobile device.

[0030] In a second step, the mobile device performs S20 authentication with the vehicle, transmitting attestation information to the vehicle. This attestation information includes not only the usual authentication data but also user information provided by the server system. The mobile device performs this authentication process primarily when approaching the vehicle.

[0031] In a third step, the vehicle extracts the user information transmitted with the digital vehicle key from the attestation information (S30).

[0032] In a fourth step, step 40, the vehicle displays user information to the vehicle user. This can be done, for example, by projecting the -2683 DE.

[0033] 5

[0034] User information can be provided via a projector in the vehicle or by display on a screen in the vehicle.

[0035] The user information can include various types of content, such as a simple welcome message, but also more detailed information like pictures, videos, music, or even a QR code that the user can scan with their smartphone.

[0036] Alternatively or in addition to the display in the vehicle, the user information can also be displayed directly on the user's mobile device as soon as they receive the digital key.

[0037] Another embodiment provides that the user information contains instructions on how to use the vehicle, which can be particularly helpful for vehicles with novel operating concepts.

[0038] In Fig. 2, a key control instance 10 provides the user information data as an addition to a digital vehicle key 20 for the vehicle user. When the vehicle user approaches the vehicle 40 with their mobile device 30, on which the digital vehicle key 20 is stored, the mobile device 30 performs authentication 35 with the vehicle 40 and transmits attestation information 50, which contains the user information. The vehicle 40 extracts the user information from the attestation information 50 and then displays it to the vehicle user, e.g., as a projection 45 by a projector 46.

[0039] The vehicle 40 extracts the user information, in particular in a control unit of the vehicle 40, which is connected to a communication unit of the vehicle 40, through which the vehicle receives the attestation information 50 from the mobile device 30.

[0040] The invention thus makes it possible to display a personalized greeting or other useful information to the vehicle user without requiring -2683 DE

[0042] No additional hardware in the vehicle or additional communication with the mobile device or the vehicle would be required. The user information is simply transmitted as part of the digital key and extracted and displayed by the vehicle.
