Abstract
A method for activating a vehicle function, of one vehicle among a plurality of vehicles, by an activating device, the device communicating with a user's portable access equipment. The vehicle function triggered on detection of the presence of the portable equipment in a predetermined zone around the vehicle, in a polling phase, and on authentication of the equipment. The method includes: selecting from the plurality of vehicles, a master vehicle and slave vehicles; each slave vehicle sending the master vehicle a specific identifier; the master vehicle sending each slave vehicle an instruction putting their polling phase on standby; increasing the frequency and/or power of the polling transmissions of the master vehicle and generating an enlarged predetermined zone around the master vehicle. If the presence of an authenticated user is detected in the predetermined zone, the master vehicle sends a wake-up instruction to the slave vehicle corresponding to the identifier triggering its polling phase; activating the vehicle function of the slave vehicle if the authenticated user is located in a predetermined zone around the slave vehicle.
