Abstract

A method for indicating authorized authentication media for a vehicle including detecting a key authorized for the vehicle via a first interface; ascertaining the authentication media that are authorized for the vehicle; and outputting an indication if, on the one hand, the key authorized for the vehicle was detected previously and if, on the other hand, at least one authentication medium was ascertained in the course of the ascertaining step, wherein the vehicle communicates with the authentication media via a second interface, which differs from the first interface. Also disclosed is a device and vehicle.

Claims

1. A method for indicating that one or more authentication media have been previously authorized for control of functionality of a transportation vehicle, the method comprising:

detecting a key authorized for controlling functionality of the transportation vehicle via a first interface of the transportation vehicle;

ascertaining whether one or more authentication media have been previously authorized to control functionality of the transportation vehicle; and

in response to the detected key having been detected previously via the first interface, outputting an indication of whether the ascertainment indicated that one or more authentication media have been previously authorized to control functionality of the transportation vehicle, wherein the indication is output via display included in the transportation vehicle;

communicating, by the transportation vehicle, with the one or more authentication media via a second interface of the transportation vehicle, which differs from the first transportation vehicle interface,

wherein the key authorized for the transportation vehicle is a primary key and the one or more authentication media is a secondary key.

2. The method of claim 1, wherein the key authorized for the transportation vehicle is a transponder which is detected via a keyless entry system of the transportation vehicle.

3. The method of claim 1, wherein the one or more authentication media that are authorized to control functionality of the transportation vehicle are configured to wirelessly communicate with the transportation vehicle only over a short range.

4. The method of claim 1, wherein the primary key is authorized to confer on the secondary key an authorization for the transportation vehicle or to generate the secondary key having the authorization for the transportation vehicle.

5. The method of claim 1, wherein the indication includes a list of the authorized authentication media, and at least one of specification of those transportation vehicle functions for each authentication medium and specification of an authorization period during which the authentication medium possesses the authorization for the transportation vehicle.

6. The method of claim 1, wherein the detection of the key authorized for the transportation vehicle is performed when the key has been inserted into an ignition lock of the transportation vehicle.

7. A device for indicating that one or more authentication media have been previously authorized for control of functionality of a transportation vehicle, wherein the device comprises:

an output; and

a controller coupled to the output and configured to detect a key authorized for controlling functionality of the transportation vehicle via a first interface of the transportation vehicle and to ascertain whether one or more authentication media have been authorized to control functionality of the transportation vehicle,

wherein the output and the controller are configured to cooperate to, in response to the controller having previously detected the detected key via the first interface, outputting an indication of whether the ascertainment indicated that one or more authentication media have been previously authorized to control functionality of the transportation vehicle, wherein the indication is output via display in the transportation vehicle,

wherein the controller is configured to communicate with the one or more authentication media via a second interface of the transportation vehicle, which differs from the first transportation vehicle interface, and

wherein the key authorized for the vehicle is a primary key and the one or more authentication media is a secondary key.

8. The device of claim 7, wherein the key authorized for the vehicle is a transponder which is detected via a keyless entry system of the transportation vehicle.

9. The device of claim 7, wherein the one or more authentication media that are authorized for the vehicle are configured to wirelessly communicate with the vehicle only over a short range.

10. The device of claim 7, wherein the primary key is authorized to confer on the secondary key an authorization for the transportation vehicle or to generate the secondary key having the authorization for the transportation vehicle.

11. The device of claim 7, wherein the indication includes a list of the authorized authentication media, and at least one of specification of those transportation vehicle functions for each authentication medium and specification of an authorization period during which the authentication medium possesses the authorization for the transportation vehicle.

12. The device of claim 7, wherein the detection of the key authorized for the transportation vehicle is performed when the key has been inserted into an ignition lock of the transportation vehicle.

13. A transportation vehicle with a device for indicating that one or more authentication media have been previously authorized for control of functionality of a transportation vehicle, wherein the device includes an output and a controller coupled to the output, wherein the controller is configured to detect a key authorized to control functionality of the transportation vehicle via a first interface of the transportation vehicle, and to ascertain whether one or more authentication media have been previously authorized to control functionality of the transportation vehicle, and the output and the controller are configured to in response to the controller having previously detected the detected key, output an indication whether the ascertainment indicated that one or more authentication media have been previously authorized to control functionality of the transportation vehicle,

wherein the controller is configured to communicate with the one or more authentication media via a second interface of the transportation vehicle, which differs from the first interface of the transportation vehicle, and

wherein the key authorized for the transportation vehicle is a primary key, the one or more authentication media is a secondary key.

14. The transportation vehicle of claim 13, wherein the key authorized for the transportation vehicle is a transponder which is detected via a keyless entry system of the transportation vehicle.

15. The transportation vehicle of claim 13, wherein the one or more authentication media that are authorized for the transportation vehicle are configured to wirelessly communicate with the transportation vehicle only over a short range.

16. The transportation vehicle of claim 13, wherein the primary key is authorized to confer on the secondary key an authorization for the transportation vehicle or to generate the secondary key having the authorization for the transportation vehicle.

17. The transportation vehicle of claim 13, wherein the indication includes a list of the authorized authentication media, and at least one of specification of those transportation vehicle functions for each authentication medium and specification of an authorization period during which the authentication medium possesses the authorization for the transportation vehicle.

18. The transportation vehicle of claim 13, wherein the detection of the key authorized for the transportation vehicle is performed when the key has been inserted into an ignition lock of the transportation vehicle.
