Abstract
The speed change ratio of a continuously variable transmission is controlled so that the actual speed change ratio approaches the basic speed change ratio at a predetermined rate of changing the speed by setting the basic speed change ratio based upon the opening degree of the accelerator and the vehicle speed. Here, when a change in the basic speed change ratio accompanying the accelerator operation is against the direction in which the actual speed change ratio approaches the basic speed change ratio, the speed is forcibly and temporarily changed to follow the change in the basic speed change ratio.
