Abstract:
1. An in-vehicle equipment remote control system comprising: a portable unit which receives a request signal and transmits a response signal in response to the request signal; and a controlling means mounted in a vehicle for periodically transmitting the request signal in a predetermined area around the vehicle, and controlling an operation of in-vehicle equipment, when triggered by reception of the response signal from the portable unit, wherein the controlling means includes wherein the microcomputer has a normal operation mode and a low-power consumption mode, instructs the request signal generation circuit to generate the request signal in the normal operation mode, and thereafter shifts from the normal operation mode to the low-power consumption mode, and wherein the request signal generation circuit utilizes the clock signals generated by the clock signal generation circuit and continues operation thereof with the clock signals even after the microcomputer shifts to the low-power consumption mode.
