<P>PROBLEM TO BE SOLVED: To provide a vehicle remote control device, by which a situation where a vehicle power supply is turned on accidentally is hardly caused even if a microcomputer operates abnormally. <P>SOLUTION: The microcomputer 20 of a controller 15 is provided with a determination signal output part 35 for outputting a determination signal Sr which has a pulse-waveform depending on the working condition (normal action/abnormal action) of the microcomputer 20. To the most upstream side of an internal relay circuit 22 of the controller 15, a relay power supply switching circuit 37 is connected. In an antenna unit 14, a monitoring circuit 38 is provided for monitoring the determination signal Sr. Upon verifying the abnormal operation of the microcomputer 20, the monitoring circuit 38 turns off the relay power supply switching circuit 37 to forcibly turn off the internal relay circuit 22. <P>COPYRIGHT: (C)2013,JPO&INPIT |
