Abstract

PURPOSE:To suppress the speed change shock on the start by installing a means for increasing the line pressure of a speed change control hydraulic circuit for a prescribed time after releasing the neutral position in the parking range when the operation signal of an air conditioner is inputted. CONSTITUTION:The throttle opening degree which determines the change point (A point) of the line pressure is shifted by the operation of an air conditioner. Further, when the stop of a vehicle is judged, the throttle opening degree is shifted to the line pressure (A point). Further, after the traveling range is selected from each range of N (neutral) and P (parking), shift to the line pressure (A point) is performed during a prescribed time. By changing the line pressure in a speed change control hydraulic circuit so that the above-described condition is satisfied, the speed change shock generated in the case when a manual shift valve of the automatic transmission is shifted to the traveling state can be surely prevented.
