Motor vehicle with a central locking unit and a remote control for its operation |
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 Izs is greater than the duration DELTA t of the communication protocol.
