Title:
WIRELESS REMOTE CONTROL SYSTEM
Document Type and Number:
Japanese Patent JPS63145150
Kind Code:
A
Abstract:
PURPOSE:To improve the safety in remote control operation by outputting an H-signal from a comparator when an instruction signal received by a received intensity detecting means is over a prescribed value and operating a trunk opened, door lock, etc. only in the case when the H-signal is outputted. CONSTITUTION:A wireless remote control system is constituted of a transmitter 2 and a receiver 3 mounted onto a car. The receiver 3 receives electric waves by a receiver 12, and the intensity (i) of the received electric wave is compared with a prescribed value (r), and if the intensity is over (r), an H-signal is outputted from a comparator 14. Further, a decoder 13 extracts an instruction signal from the signals received by the receiver 12, and outputs a prescribed operation signal. A trunk opener T and door lock D can be operated only in the case when the H-signal is outputted, by installing AND gates 15 and 16 between the comparator 14. In remote control, the safety in remote control operation can be achieved without operating the trunk and door lock.
