<p>A hydraulic pressure correction method of an automatic transmission is provided to change the speed by applying a correction pressure for friction element according to a deceleration rate. In a hydraulic pressure correction method of an automatic transmission, the speed of a car is computed(S1), and the opening of a throttle valve is sensed(S2). The foot up of a lift and speed change is determined based on the opening of the throttle valve according to a deceleration rate(S3). A correction hydraulic pressure is determined according to the deceleration rate(S4), and the final hydraulic pressure is determined based on a corrected hydraulic pressure(S5). The determined final hydraulic pressure is applied to a friction element.</p> |
