<p>PURPOSE:To improve responsiveness especially during the start of a vehicle and prevent the increase of a car speed against a driver's will. CONSTITUTION:In addition to feedback control, feed forward control is employed. When an accelerator opening is comparatively low during the start of a vehicle, step motors 29A and 29B are driven and controlled at a lowermost speed and when an accelerator opening is high, the step motors 29A and 29B are driven and controlled at a maximum speed. Therefore, fine operability is improved and a vehicle is rapidly started and accelerated without a delay for stepping on of an acceleration pedal 1. Further, by setting the upper limit of a feedback control region such that a change gear ratio is not maximized when the accelerator opening is low, the rapid increase of a change gear ratio is prevented from occurring when the accelerator opening is low.</p> |
