<p>PURPOSE:To prevent slippage of a driving V-belt by providing a means for modifying a control target engine rotary speed, a control target driving pulley rotary speed or a control target speed change ratio on the basis of a deceleration speed during deceleration under fully closed throttle operation. CONSTITUTION:When the brake of a vehicle is abruptly functioned under 1 small speed change condition and a considerable deceleration is caused a speed change controller 300 modify the speed change ratio to the increasing side when compared with a normal case according to the degree of deceleration. Consequently, as the difference between a control target level and an actual level increases, a signal for shifting to the maximum speed change ratio side is outputted to the motor 110, 224. Consequently, the speed change ratio of a continuously variable transmission is modified to the maximum speed change ratio condition prior to stoppage of the vehicle. In such a manner, slippage of a V-belt due to re-driving immediately before or after stoppage can be prevented.</p> |
