Abstract: At least one vehicle and at least one key element, each associated with a corresponding vehicle, are configured to exchange data with one another via a system that determines the vehicle position and the position of the key element. The system places the vehicle in a driving operating mode when the vehicle position and the key element position are essentially the same, in particular when the key element is located inside the vehicle. At least one vehicle function that can be activated when the vehicle is stationary is automatically switched on depending on a current key element position. This may occur when a key element position is changing relative to the vehicle position, but the vehicle and the associated key element are remote from one another, such as separated by at least ten meters.

Abstract: A method for determining potential damage to a vehicle battery. In the method, at least one acceleration data set relating to a vertical acceleration of a motor vehicle, which includes the vehicle battery, is determined. The at least one acceleration data set is then checked for the presence of a predetermined damage criterion, which indicates the potential damage to the vehicle battery. Finally, only for the case that the damage criterion is determined in the at least one acceleration data set, a control signal for actuating an actuator device of the motor vehicle is generated.
