Abstract
A system and method for automatically controlling a vehicle speed to a desired cruising speed in which, when a given operation of the set switch (turn off after turn on of the set switch) is carried out, control constants used in a control equation expressed as (K.times..alpha.+.epsilon.).times.G in accordance with which the vehicle speed is controlled so as to coincide with a stored vehicle speed, are changed from those used when the vehicle is cruisingly run at the stored vehicle speed. The stored vehicle speed is the vehicle speed stored when the given operation of the set switch is carried out. Therefore, the vehicle speed speedily converges the stored vehicle speed with an overshoot of the vehicle speed at such a transient state suppressed to a minimum regardless of vehicle models, environmental factors, and adjustment state of a control wire connected between an actuator and throttle valve.
