Abstract
The continuously variable transmission (CVT) assembly includes a CVT including a drive pulley, a driven pulley, and an endless rotatable device coupled between the drive pulley and the driven pulley. The CVT assembly also includes an actuator coupled to the drive pulley. The CVT assembly also includes an angle sensor coupled to the endless rotatable device such that the angle sensor is configured to measure an angular position of the endless rotatable device. The CVT assembly also includes a controller in communication with the actuator and the angle sensor. The controller is programmed to: (a) determine a speed ratio of the CVT based on the angular position of the endless rotatable device; and (b) control the actuator to adjust the clamping force exerted on the drive pulley in response to determining the speed ratio of the CVT.
