ABSTRACT:
An apparatus for controlling a hydraulically operated continuously variable transmission for a motor vehicle, which has an input member, an output member and a power transmitting member 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 for detecting an input torque of the transmission, a hydraulic actuator 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 to thereby change the pressure of engagement of the power transmitting member, with the detected input torque of the transmission.
