摘要:
A central locking system of a motor vehicle is provided with communication between the transmitter of the remote actuation unit and the receiver of the central locking system in a frequency-hopping spread spectrum mode where M channels are used of a total of N channels of the spread spectrum frequency band chosen, for example, an I/S/M band of 433 MHz to 435 MHz. Switching is effected from one channel to another channel of the N channels in accordance with a timing pattern in which the timing interval I.sub.zs is greater than the duration .DELTA.t of the communication protocol.

摘要:
The invention relates to a device for the wireless transmission of data and energy between an element to be mounted on or in a vehicle body, especially a vehicle sliding door (2), a vehicle seat or a comparable additional unit, and a vehicle body (1). The basic design of the inventive device comprises an electric power source (18), control electronics (17, 17′) mounted in the vehicle body and at least one pertaining coil (20) also mounted in the vehicle body. The device further comprises control electronics (11) mounted in the element and at least one pertaining coil (19) also mounted in the element. Both coils (19, 20) are inductively coupled via a common transmitting/receiving path to transmit data and energy. According to the invention, the coil (19) mounted in the element is enclosed by the coil (20) mounted in the vehicle body and can be displaced in a longitudinal direction within the coil (20) mounted in the vehicle body or vice versa.
