发明名称 Process for the emission of a request toward a badge
摘要 In this process for emission of a request toward a badge of a remote control system, the request is transmitted by a signal of a predetermined frequency, with the help of antennas adapted to emit within the interior of the passenger compartment of a vehicle. The amplitude of the signal transmitting a single and same request varies in the course of the transmission of this same request between two end values (A1, A2), and in that the amplitude corresponding to the lower end value (A2) is sufficient that the portion of the request emitted with this minimum amplitude (A2) be perceived only within the predetermined zone.
