Abstract
The automobile vehicle (V) is equipped with a 'hands-off' access system comprising a recognition device placed in the vehicle with several antennas and a portable identification device or badge for remote communication with the recognition device to automatically control locking or unlocking of the said vehicle doors and/or authorization to start the said vehicle. The said antennas have intersecting coverage areas (Z1, Z2, Z3), and the recognition device is designed to activate each antenna in turn in order to detect a response or lack of response of the identification device depending on which antenna is activated and to localize the presence of the identification device in a particular coverage area of the antennas based on detections of response or lack of response of the identification device.
