Abstract
PURPOSE:To safely and surely cancel malfunction and prevent accidents by shutting off the power supply to a specified circuit or means when malfunction is detected in running at constant speed or when the brake pedal is operated. CONSTITUTION:The operation quantity of an accelerator pedal 1 is detected by a decting means 21, and the detected signals are input in a drive circuit 23 through an addition circuit 22 to drive a throttle 5 by means of an actuator 24. On the other hand, car speed is detected by a detecting means 56, and the detected signals and the reference signal memorized in a memory 41 are compared by a comparison circuit 42, and the comparison signals are also input in the addition circuit 22 through an addition circuit 43 and switch 67 to allow a car to run at reference speed maintaining constant speed. At this time when malfunction is detected, the output of an AND gate 93 is input in an FF55 through an OR gate 94, and the FF55 is reset. This turns switches 101 and 102 off for shutting off the power supply to blocks 8 and 9.
