Abstract
A belt continuously variable transmission includes a primary pulley (), a secondary pulley (), a belt (), a hydraulic pump (), a speed ratio control valve () that regulates hydraulic pressure from the hydraulic pump () and supplies the hydraulic pressure to the primary pulley () and the secondary pulley (), a motor () that drives the speed ratio control valve (), a controller () that controls the motor (), and an oil temperature sensor () that detects the temperature of a working fluid. The controller () stops energization to the motor () when the temperature of the working fluid becomes greater than a first predetermined temperature while the vehicle is at rest in an idling state.
