Abstract:
A motor vehicle (V) equipped with an identification device for controlling means comprising means for locking the opening leaves (3-5) and/or means for preventing the starting of the vehicle, said identification device remotely exchanging data with an identifier worn or carried by a user, so as to allow access to the vehicle when the identifier has been authenticated by the identification device, the identification device being connected to a number of external antennas (1, 2; 11, 12) on the vehicle so as to allow dialog between the identification device and the identifier, when the identifier is positioned in the area of coverage of said antennas, wherein at least one pair (1, 2; 11, 12) of said external antennas comprises a common area of overlap (III, XIII), so that the identification device is able to detect the presence of an identifier in said common area of overlap with a view to said device controlling a given means when said pair of antennas receives a signal from the same identifier, each antenna of said pair of antennas also comprising its own area of coverage (I, II; XI, XII) without any mutual overlap, so that the identification device is capable of detecting the presence of an identifier in one of the two aforementioned areas of coverage with a view to said device controlling a means other than the aforementioned given means when the associated antenna receives only a signal from the identifier.
