METHOD FOR NEUTRALIZATION OF A PORTABLE REMOTE REMOTE CONTROL BOX IN AN INDOOR AREA OF A VEHICLE EQUIPPED WITH A HANDS-FREE ACCESS DEVICE, AND CORRESPONDING HANDS-FREE ACCESS DEVICE

摘要

The invention relates to a method of neutralizing a portable housing (B), said identifier, when the latter is forgotten in an interior zone (3), called a utility vehicle, of a vehicle (1) equipped with a hands-free access device comprising at least one external transmitting antenna (9) for transmitting identification identification signals (B) situated outside the vehicle (1), said external antenna having a cover (Z9) formed an outer zone extending outside the vehicle (1), and an inner zone (Zc) extending inside the vehicle in the utility zone (3) thereof. According to the invention, this method of neutralization consists in installing, opposite each external antenna (9), an inner transmitting antenna (11), said antenna counter, whose cover (Z11) covers at least the inner zone (Zc) of the cover (Z9) of said external antenna, and to control, simultaneously with the transmission of each signal S1 of identification by this external antenna, the emission, by the counter antenna (11), of a parasitic signal S2 designed to scramble said identification signal.
