Abstract
A method for scanning for presence inside a vehicle, using a scanning device including at least one internal and one external ultra-wideband transceiver module for locating portable 'hands-free' access equipment carried by a user. The device has an Ultra High Frequency communicator for communicating with the equipment. The method includes: a) detecting locking of the vehicle; b) for a predetermined duration: i) scanning for presence inside the vehicle with the internal module; ii) simultaneously transmitting a request to the equipment for detecting a U-turn by the user; iii) if a U-turn signal is received, stopping scanning and determining the position of the user with the two modules; iv) if presence is detected inside the vehicle, stopping scanning and transmitting a warning; c) when the duration has elapsed, if no U-turn signal is received and if no presence is detected, the position of the user is determined with the two modules.
