Abstract: A processing unit includes a first communication interface that is designed for communication with a server device and/or a mobile device. The processing unit also has a second communication interface, which is designed for communication with the mobile device. The processing unit further has an internal communication interface of the processing unit, which is designed for communication with a vehicle bus network of the vehicle. The processing unit is designed to receive vehicle access data, which is representative of an access authorization of a driver to the vehicle via the second communication interface. The processing unit is also designed to determine depending on the vehicle access data a release signal for enabling a use of the vehicle and to provide it to the internal communication interface. The processing unit is also designed to receive vehicle analysis data via the internal communication interface.

Abstract: A motor vehicle is controlled using a vehicle-external mobile terminal. A communication connection is established using a first transmission/reception device of the motor vehicle and second transmission/reception device of the mobile terminal. A distance and/or relative position of the mobile terminal in relation to the motor vehicle is ascertained by evaluating a radio signal transmitted via the communication connection. Clearance data is generated using a control circuit of the motor vehicle or of the mobile terminal based on the ascertained distance and/or the ascertained relative position. The clearance data indicates that a predetermined control command can be transmitted from the mobile terminal to the motor vehicle and/or is accepted from the mobile terminal by the motor vehicle.
