<p>A motor vehicle having a central locking system which comprises a plurality of motor vehicle locks, and having a remote control installation, which remote control installation has at least one transmitter which comprises a coding device and which acts as a key, as well as a receiver which acts on at least one motor vehicle lock and which comprises a complementary decoding device, and which using high-frequency frequency modulation. Control commands in the form of transmission protocols are transmitted and received, respectively, in order to operate the central locking system. The remote control installation is designed as a spread spectrum remote control installation which comprises a plurality M of channel fields in a predetermined frequency band having a number of N channel fields (M * less than or equal to * N), and employs the frequency hopping technique. Switch-over from one channel field to another channel field of the N channel fields is effected according to a timing scheme comprising a timing algorithm and time intervals I ZS . The time intervals I ZS of the timing scheme are longer than the time difference * capital Greek delta * t between the transmission protocols.</p> |
