ABSTRACT:
In a V-belt type CVT, an actual-shift-ratio corresponding operated position of a step motor is calculated through conversion of an actual shift ratio expressed by the rotational-speed ratio between primary and secondary pulleys. A displacement amount is calculated between the actual-shift-ratio corresponding operated position of the step motor and an actual position thereof. A correction amount of the line pressure is calculated to reduce the displacement amount, and the line pressure is corrected in accordance therewith.
