A procedure for scanning identifying badges for automotive vehicle comprising an identification device designed for the remote interchange of data with the identifying badges. The badge scanning comprises the repeated transmission, by the identification device, of identification requests for the attention of the badges. This procedure comprises the steps of detection () of a triggering event out of a predetermined set of triggering events; execution () of a preliminary test following the detection of the triggering event; and execution () of at least one scan, according to the result of the preliminary test.

Procedure for scanning identifying badges for automotive vehicle

A method for identifying and authorizing unlocking or starting of a motor vehicle for a hands-free access system includes a central unit exchanging identification messages with identification units according to a communication procedure. The communication procedure includes emitting an identification message from the central unit to the identification units, emitting a message indicating a presence of the identification units having received the identification message to the central unit, emitting a selection message by the central unit to select one particular identification unit to reply to the identification message, and emitting an additional identification message, where at least one of the emitting of a message indicating the presence of the identification units and the emitting of the selection message is performed between emitting the identification message and the emitting of the additional identification message so as to enhance the security of interchange between the central unit and the identification units.
