ABSTRACT:
A belt type continuously valiable transmission (CVT) comprises a pair of input pulleys, a pair of output pulleys and a belt trained over input and output pulleys to transmit power. Each pair of the pulleys has a hydraulic cylinder for pressing the pulleys against the belt. A line pressure used in one cylinder is controlled by adjusting an electric pressure regulating valve. A correction value is calculated which corresponds to the square of the rotational speed of the hydraulic cylinder to which line pressure is supplied. The value of control signal of the pressure regulating valve is corrected in accordance with the correction value, so that the error of the line pressure due to a centrifugal force is compensated for.
