制御装置。 A vehicle speed detection means for detecting the vehicle speed, a microcomputer for outputting a control signal to the vehicle control equipment based on the vehicle speed detection signal, and an operating voltage to the microcomputer when the ignition key switch is turned on and when the operating voltage to the microcomputer becomes less than a predetermined value. In a vehicle control device comprising a reset control circuit that outputs a reset signal to a microcomputer when the vehicle speed decreases, after the reset signal is output from the reset control circuit and the microcomputer is restarted, the vehicle speed detecting means outputs a reset signal. a timer for measuring the elapsed time until the vehicle speed signal is read, and a predetermined initial value of a control signal output to a control device of the vehicle when the elapsed time measured by the timer is less than a predetermined value. and control initial value setting means for setting the initial value of the control signal to a value corresponding to a vehicle speed of 0 when the measured time is equal to or greater than a predetermined value. control device.
