ABSTRACT:
To provide a wireless vehicle control system having a compact receiver with small current consumption, a receiver includes a receiving circuit for receiving a modulated command signal from a transmitter, a demodulation circuit for demodulating and outputting the received command signal, and a power source control circuit for starting and stopping supply of power to the receiving circuit and the demodulation circuit. A control device in the system includes a CPU for issuing to the power source control circuit a signal instructing a start of supply of power, for subsequently discriminating the control signal received from the demodulation circuit and outputting a drive signal in accordance with a discrimination result thereof, and thereafter, for issuing to the power source control circuit a signal instructing a stop of supply of power; a drive circuit for receiving the drive signal and causing a door lock motor to be operated; and a power source supply circuit for constantly supplying power to the CPU.
