ABSTRACT:
Clutch pressure is reduced to an initial pressure, and a transmission operation state is stored, when a vehicle is stopped with an engine in an idling state. The clutch pressure is further reduced at a constant change rate and the amount of time is measured until the turbine rotation speed increases to the predetermined rotation speed. Based on the measured amount of time, a correction amount is computed for the initial pressure necessary to increase the turbine rotation speed to the predetermined rotation speed in a predetermined amount of time. The correction amount is stored in a memory region corresponding to the transmission operation state when the clutch pressure is reduced to the initial pressure. The initial pressure is corrected according to the correction amount stored in the memory region corresponding to the transmission operation state when the clutch. pressure is reduced.
