Abstract
Speed change inhibition control for inhibiting change of the speed ratio of a continuously variable transmission (CVT) is executed when an input shaft speed of the CVT is lower than a predetermined ABS-operating-time upper-limit input shaft speed. Therefore, the speed ratio of the CVT can be changed to the largest reduction ratio until it is determined that the input shaft speed of the CVT is lower than the predetermined ABS-operating-time upper-limit input shaft speed. Thus, during ABS operation of an ABS control device before the vehicle is stopped, the speed ratio can be returned to the largest reduction ratio in a condition where engine brake force is not excessively applied, and sufficient driving force of the vehicle or starting response is obtained when the vehicle is re-started.
