In the case where a belt return of a continuously variable transmission is not determined when the vehicle speed has become equal to or lower than a threshold value, control that causes a hydraulic actuator to have an intermediate pressure by setting a duty of a duty solenoid based on an input torque and an oil temperature and closing control are repeatedly performed, in accordance with the running and the stopping of the vehicle. As a result, it is possible to inhibit the continuously variable transmission from being shifted up due to a gradual increase in the hydraulic pressure in the hydraulic actuator caused by a line pressure seeping to the hydraulic actuator side through a small clearance in a spool of a flow rate control valve in a hydraulic circuit, and it is also possible to allow the continuously variable transmission to be shifted down.
