Abstract
PURPOSE:To make the driving quantity of an actuator conform in the whole vehicle speed zone and prevent overshoot and undershoot by varying the value of a control constant which is added to a control signal at the time of shifting from acceleration (deceleration) to deceleration (acceleration) in accordance with a vehicle speed. CONSTITUTION:In response to the operation of a command switch 2 which outputs a cruise command signal, a vehicle speed memory means 3 stores the operation data of a vehicle speed sensor 1. A control means 6 calculates the control signal of an actuator 5 in accordance with the difference between an actual vehicle speed and a stored vehicle speed, while varying the valve of a control constant which is added to a control signal at the time when the control signal is shifted from acceleration to deceleration or from deceleration to acceleration, in accordance with a vehicle speed. Thus, when the control signal is shifted from acceleration (deceleration) to deceleration (acceleration), the value of the control constant added to the control signal is varied in conformity with the change in vehicle speed, to drive the actuator 5 with the most conforming controlling quantity to the vehicle speed at that time.
