Abstract

A transmission controller increases hydraulic pressure supplied to a secondary pulley and decreases hydraulic pressure supplied to a primary pulley to shift a variator to a mechanical Low speed ratio when the hydraulic pressure supplied to the primary pulley and the secondary pulley vibrates. The transmission controller shifts the variator from the mechanical Low speed ratio to a High side when a sub-transmission mechanism is downshifted during controlling a speed ratio of the variator at the mechanical Low speed ratio.
