发明名称 Control device and control method for continuously variable transmission
摘要 When a speed ratio (ip) at a stopping time of the vehicle cannot be stored, an operating position of a step motor (27) 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 (P1), and a pulley ratio (the speed ratio (ip)) between a non-rotating primary pulley (2) and a non-rotating secondary pulley (3) 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.
