Abstract
In a system for harmonizing a motor vehicle's status information (S) between at least two ID transmitters (, . . . ) of a vehicle-accessing device, the vehicle status (S), together with a reference time (t), corresponding to the vehicle status (S), of a reference timing element of a vehicle-side control unit () can be sent by the unit via at least one transceiver unit () to at least one first mobile ID transmitter () over a first radio transmission () and stored; and the vehicle status (S) can be sent over a second radio transmission () from the first ID transmitter () to at least one second ID transmitter (, . . . ) and stored. This is advantageous in that an ID transmitter () can obtain information about the vehicle status Snot only via the vehicle () itself but also via another ID transmitter (). The invention is especially suitable for accessing and locking systems for motor vehicles.
