Abstract
PURPOSE:To avoid giving a feeling of acceleration to a driver at the time of high engine speed with a throttle valve being totally closed by providing a correcting means for correcting the target rotating speed of a primary pulley in the direction of lowering an engine output torque. CONSTITUTION:While driving a vehicle, an actual change gear ratio is calculated 60 according to a primary pulley rotating speed and a secondary pulley rotating speed and a target primary pulley rotating speed is retrieved 61 from the actual change gear ratio and a throttle opening, in a control unit 40. Also, a target change gear ratio is calculated 64 from this target primary pulley rotating speed and the secondary pulley rotating speed, and a speed change speed is calculated 65 based on the deviation between the target change gear ratio and the actual change gear ratio, etc. to control a change gear ratio controlling solenoid valve 28. In this case, when engine speed is high with a throttle valve being totally closed, the target primary pulley rotating speed can be corrected in the direction of lowering an engine output torque through a target primary pulley rotating speed correcting means 63.
