Abstract
A vehicular remote control system includes, on a portable device side, a portable device side first receiver, a portable device side transmitter, and a portable device side second receiver and, on a vehicle side, a vehicle side first transmitter, a vehicle side second transmitter, and a vehicle side receiver. Transmitting and receiving a request signal requesting an identification signal, the identification signal, an interrogation signal, and a response signal between the portable device and the vehicle allows a door lock actuator to be operated if the portable device is legitimate. When the vehicle side second transmitter or the portable device side second receiver breaks down, transmission and reception of a second request signal and the interrogation signal is carried out using the vehicle side first transmitter and the portable device side first receiver, thereby making the door lock actuator operate unhindered without the need for providing special alternative means.
