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.
