AbstractIn a speed control system for vehicles, a speed-difference calculation circuit calculates an absolute value of a time difference between a predetermined period of time corresponding with a desired speed and the actual period of time corresponding with the actual speed, an acceleration calculation circuit calculates an absolute value of a time difference between the preceding and following actual periods of time within a limited range, and correction signal generator calculates a sum of the absolute values when each sign of the calculated time differences is positive or negative and calculates a difference between the absolute values when respective signs of the calculated time differences are opposite to each other. The signal generator selectively produces correction signals related to the calculated sum and the calculated difference. A distribution circuit produces a control signal in response to the respective correction signals, and an actuator controls the opening angle of the engine throttle in response to the control signal.
