Abstract: A motor vehicle has a processor device to run application programs in a first communication zone and a storage device for vehicle control data, by which a driving behavior of the motor vehicle is determined. The storage device is arranged in a second communication zone of the motor vehicle. In order to allow a modification of the vehicle control data at a later stage using an application program and thus provide protection against an undesired manipulation of the vehicle control data, the first and the second communication zones are coupled by a monitoring device that forwards new data, which an application program is attempting to transmit from the first communication zone into the second communication zone, to the second communication zone only if the monitoring device has detected that the new data leads to a safe motor vehicle driving behavior defined by a specified safety criterion.

Abstract: A method transmits data between a mobile telephone and a motor vehicle.
