METHOD OF SCREWING A RADIO FREQUENCY LINK IN A REMOTE CONTROL SYSTEM OF A MOTOR VEHICLE

摘要

The invention relates to a method of scanning, by a central unit (embedded in a vehicle), a radio frequency link on which wake-up signals (R1, R2) and data signals (D1, D2) are capable of being transmitted by a remote control device, said central unit comprising at least two reception antennas, which comprises the following steps: the central unit scans the radio frequency link with a single antenna among the at least two receiving antennas, with a period polling device (T) ensuring, in the presence of a radio frequency frame (50), that the radio frequency link is scanned during each wake-up signal (R1, R2) of this frame, • the central unit changes the antenna used for scanning every N scan periods, N being a predefined integer providing, in the presence of a radio frequency frame (50), that each antenna is used during at least one wake-up signal among the at least two wake up signals of this frame.
