SYSTEM FOR HANDS-FREE ACCESS TO A VEHICLE

The invention relates to a system for hands-free access () to a vehicle (), comprising: —a hands-free access device () configured to: —transmit a location frame () comprising a modulated signal () and a pure carrier signal (); —receive a measurement of the received signal strength of a primary received signal (RSSI) performed on said pure carrier signal () by a hands-free identifier (); —receive information () on the absence or presence of noise () in said location frame (); —depending on said measurement of the received signal strength of a primary received signal (RSSI) and on said information () on the absence or presence of noise (), authorize or prevent access to said vehicle (); —a hands-free identifier () configured to: —receive said location frame (); —perform a measurement of the received signal strength of a primary received signal (RSSI) on said pure carrier signal (); —send said hands-free access device () said measurement of the received signal strength of a primary received signal (RSSI); —check the presence of noise () in said location frame (); —send the hands-free access device () information () on the absence or presence of noise () in said location frame ().
