Beschreibung
Zusammenfassung:	In this vehicle, equipped with a recognition device (1) capable of remotely exchanging data with an identification member (11) worn or carried by a user to allow access to the vehicle when the identification member has been authenticated by the recognition device, the latter being connected to a pair of lateral antennas (2, 3) each having, when powered at nominal power, a zone of coverage encompassing the interior of the vehicle and extending laterally on both sides thereof to allow a dialog between the recognition device and the identification member when the latter is located in the zone of coverage of at least one of the antennas, the recognition device (1) is capable, in response to action by the user on an external member placed on one side of the vehicle, of causing the antenna located on the same side as the external member to be powered at nominal power and of causing the antenna located on the opposite side of the vehicle to be powered at a reduced power so that the latter antenna has a reduced zone of coverage (Z'1).
