摘要
An apparatus for controlling a hydraulically operated continuously variable transmission for a motor vehicle, which has an input member (pulley 36, not shown), an output member (pulley 38) and a power transmitting member (belt 40) connecting the input and output members, and whose power transmitting capacity changes with a pressure of engagement of the power transmitting member with the input and output members. The apparatus includes a torque detector (106, 108, 110) for detecting an input torque of the transmission, a hydraulic actuator (hydraulic cylinder 46) adapted to receive a controlled pressure for controlling the pressure of engagement of the power transmitting member, and a device for changing the area of the pressure-receiving surface of the hydraulic actuator by applying pressure to one or both of the hydraulic chambers (76, 78) to thereby change the pressure of engagement of the power transmitting member, with the detected input torque of the transmission.
