PROBLEM TO BE SOLVED: To carry out feed back control of a gear ratio just after start rapidly so as to start smoothly by shifting a target gear ratio from the lowest value to a Hi side on the basis of a prescribed correction value for a prescribed time after start of a vehicle is detected. SOLUTION: A pair of variable pulley is set to a target gear ratio. In change of the gear ratio, a shift control valve 102 is driven by a feed back means 104 so as to match the driving rate of an actuator according to the target gear ratio with the real gear ratio of a continuously variable transmission. During stop, start of the real gear ratio is carried out from a lowest position by an initializing means 105. During a prescribed time after start of a vehicle is detected, the target gear ratio of the actuator is shifted from a lowest side to a Hi side on the basis of a prescribed correction value. A shift control valve 102 is displaced from the lowest position to the Hi side, and the feed back means 104 is operated surely just after start. |
