Abstract
An identification device for controlling locking of the opening leaves of the vehicle. The identification device is capable of remotely exchanging data with an identifier carried by a user, so as to allow access to the vehicle. The identification device is connected to a number of external antennas so as to allow dialog between identification device and the identifier. At least one pair of the external antennas have a common area of overlap, so that the identification device is able to detect the presence of an identifier in the common area of overlap when the pair of antennas receives a signal from the same identifier. Each antennas of the pair also has its own area of coverage 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.
