Abstract

A device for exchanging data with a motor vehicle having a portable transponder, which is provided with a memory unit for storing authorization information, the transponder having an arrangement for exchanging data with a vehicle management system, via which the authorization information can be influenced by the vehicle management system, the transponder having a further data-exchange arrangement for transmitting the authorization information to a control unit arranged in a vehicle to aftain operation authorization and/or access authorization of the vehicle.

Claims

1. A device for exchanging data with a motor vehicle, comprising:

a control unit situated in the vehicle;

a vehicle management system; and

a portable transponder including a memory unit for storing at least one piece of authorization information, the transponder exchanging data with the vehicle management system, the vehicle management system influencing the authorization information, the transponder transmitting the authorization information to the control unit to obtain authorization for normal vehicle operation.

2. The device according to

claim 1

, wherein at least one of the vehicle management system and the control unit transmits at least one piece of additional information to the transponder to set user-dependent functions.

3. The device according to

claim 1

, wherein the vehicle includes a navigational system situated in the vehicle, and wherein the vehicle management system transmits destination information, for inputting the destination for the navigational system, to the transponder to be relayed to the navigational system.

4. The device according to

claim 1

, wherein the vehicle management system transmits resources to the transponder to restrict a scope of use of the vehicle.

5. The device according to

claim 1

, wherein the control unit transmits a characteristic usage quantity of the vehicle to the transponder.

6. The device according to

claim 1

, wherein the vehicle management system selects an available vehicle based on a vehicle database.

7. The device according to

claim 1

, wherein the transponder relays usage information determined in the vehicle to the vehicle management system.

8. The device according to

claim 1

, further comprising at least one of a vehicle database and a user database for storing at least one of:

additional information, resources, and a characteristic usage quantity.

9. The device according to

claim 1

, wherein the transponder exchanges data bidirectionally with the control unit and with the vehicle management system.
