<p>PURPOSE:To certainly work a door lock without error action when a vehicle comes to a constant speed or higher, by driving a lock device when a vehicle speed detected by a vehicle speed sensor exceeds a specified speed continuously plural times. CONSTITUTION:The running speed of a vehicle is detected by a vehicle speed sensor 11, and its output signal is converted to a vehicle speed by a converter circuit 12, and by a detecting circuit 13, it is detected whether the speed is a constant or more value, or not. After that, by a counting circuit 14, the output of the detecting circuit 13 is counted, and when a specified output number is counted continuously plural times, then output is directed to a lock device 15, and a door lock is worked. As a result, by noise generated on an output line, the malfunction of the door lock can be prevented from being generated.</p> |
