Wireless vehicle control system
First Claim
1. A wireless vehicle control system comprising:
- a receiver having no central processing unit but includinga receiving circuit for receiving a control signal sent from a transmitter carried by a rider;
a demodulator for demodulating said control signal received by said receiving circuit to provide a demodulated control signal; and
a power source control circuit for selectively starting and stopping supply of power to said receiving circuit responsive to an instruction signal; and
a control device disposed in said vehicle remote from said receiver, said control device includinga signal discrimination circuit for outputting to said power source control circuit an instruction signal indicative of said starting of supply of power at every predetermined timing, and for subsequently inputting said control signal from said receiver, for discriminating said demodulated control signal, for outputting a drive signal in accordance with a discrimination result, and for outputting to said power source control circuit said instruction signal indicative of said stopping supply of power;
a driver circuit for inputting said drive signal and causing vehicle equipment to operate; and
a power source supply circuit for constantly supplying power to said signal discrimination circuit.

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.
