Abstract
A method for locating, via ultra high frequency, a mobile device (T) for 'hands-free' access to a vehicle (V), via a locating device (D') on board the vehicle (V), the locating device (D′) including an ultra high frequency transceiver (′), an electrical power supply source (Vcc) and an antenna (A′), the locating method being noteworthy in that the transceiver (′) is disconnected from the antenna (A′), and that the transceiver (′) is connected to an attenuation module (M, M, M) located at a predetermined distance (L, L, L) from the transceiver (′) and including an impedance (Z, Z, Z) of predetermined value connected to ground, the predetermined distance (L, L, L) between the transceiver (′) and the attenuation module (M, M, M) and the predetermined value of the impedance (Z, Z, Z) defining an area (A, A, A) for locating the mobile device (T) around the vehicle (V).
