METHOD FOR THE PROVISIONAL INHIBITION, IN ITS DETECTION IN A LOCKED VEHICLE, OF A PORTABLE REMOTE CONTROL BOX, IDENTIFIED, OF A HANDS-FREE ACCESS DEVICE

摘要

The invention relates to a temporary inhibition method, when it is detected in a locked vehicle (V), of a portable remote control unit (B), called an identifier, of a hands-free access device adapted for implementing vehicle access authorization (V) procedures comprising an initial identification procedure of controlling the periodic transmission, by a central unit (4), of a data frame incorporating a preamble consisting of a predefined wake-up code identifiable by the identifier (B). According to the invention, the inhibition method consists in defining a first awakening code at least for the procedure for temporary inhibition of the identifiers (B), and a second wake-up code specifically for the identification identification procedure. (B), and to establish temporary inhibition procedures of controlling the transmission of a specific data frame incorporating, in preamble, the first wake-up code, and adapted to control a deactivation of the recognition, by each identifier (B) referred to, the second wake up code.
