Abstract: A method and device for the remote control of a function of a vehicle is disclosed. Images of the vehicle are recorded by a camera which is integrated in the mobile control unit. A visual signal is generated at a predetermined position on the vehicle, where remote control is only enabled if the visual signal is recorded by the camera. The device for the remote control of a function of a vehicle includes a mobile control unit with an integrated camera to record the images of the vehicle. A signal generation unit is arranged at a predetermined position on the vehicle for the generation of a visual signal and the vehicle includes a function unit for the control of the function. The function unit is formed in such a way that remote control is only enabled when the visual signal is recorded by the camera.

Abstract: A system for controlling an access authorization and/or driving authorization for a vehicle includes at least one mobile communication device and a control unit in the vehicle that receives and checks authorization data sent from the mobile communication device. The mobile communication device has a data carrier for storing the authorization data. The data carrier has at least one protected storage region for the storage of the authorization data. A database server transfers encrypted authorization data to the data carrier for storage in the protected storage region.
