Abstract
When a speed ratio (ip) at a stopping time of the vehicle cannot be stored, an operating position of a step motor () is initialized to a home position such that a primary pulley pressure (Ppri) is completely drained, a secondary pulley pressure (Psec) is increased to a predetermined pressure (P), and a pulley ratio (the speed ratio (ip)) between a non-rotating primary pulley () and a non-rotating secondary pulley () is set at a lowest speed ratio. As a result, the primary pulley pressure (Ppri) is supplied reliably, and the startability of the vehicle improves.
