摘要： Control device for continuously variable transmission (4) with auxiliary transmission having variator (20); hydraulic pressure control circuit (11) having primary pressure solenoid (11b); and transmission ratio controller (12) controlling the transmission ratio of variator (20) by feedback control. The transmission ratio controller (12) has a high limiter control unit ( Fig. 5 ) that, when receiving a high transmission ratio limiting request, performs a high limiter control that limits the transmission ratio to a High limit line. The transmission ratio controller (12) also has a primary pressure lower limit regulation control unit ( Fig. 4 ) that, when operation of the high limiter control is started during a time period when the transmission ratio is present at a High transmission ratio side with respect to the high limit transmission ratio, regulates a decrease of a primary command pressure to the primary pressure solenoid up to a High limiter-operated final target primary lower limit pressure.
