PURPOSE:To prevent overshoot by satisfactorily carrying out feed-back control for the line pressure of a hydraulically operated transmission, particularly in view of a delay in variation in actual line pressure due to a change in desired line pressure and a change in basic control volume upon occurrence of a variation in operating condition. CONSTITUTION:A hydraulic control device for a hydraulically operated transmission, comprises a desired hydraulic pressure setting means 71 and a basic control volume setting means 72, and a feed-back control computing means 74 for computing a feed-back control value in accordance with a deviation between an actual line pressure at the present time, and a line pressure corresponding to an operating condition at the time which is a setting time before the present time. |
