Abstract

The invention relates to a method for protecting against unauthorized use of a vehicle which has bidirectional communication with a master station, whereby it is possible not only to transmit exclusively a position message of the vehicle to the master station or to transmit exclusively enabling signals to the vehicle from the master station, but also to make the communication appropriate to requirements. The necessary transmission of information is substantially reduced in that the enabling signal is broadcast only when requested by the vehicle. On the other hand, it is still not possible for the enabling to be carried out at the vehicle end only.
