Abstract
PURPOSE:To reduce the amount of overshoot and undershoot without worsening riding comfortableness by calculating the pulse width for operating an actuator on the basis of the gain of a pulse width calculating means, speed deviation, and acceleration. CONSTITUTION:Based on the deviation signal from a speed deviation calculating means 3 and the acceleration signal from an acceleration calculating means 4, a pulse width calculating means 5 calculates the pulse width of a pulse signal having a specified period. Receiving the pulse signal from the pulse width calculating means 5, an actuator 6 controls a throttle valve 7 to be opened or closed. A time measuring means 9 measures the time elapsed after transient state has been brought about by a transient mode starting means 10, and judges that a specified time has elapsed. Receiving the outputs both from an acceleration storing means 8 and from the time measuring means 9, a gain control means 11 controls the gain of the pulse width calculating means 5.
