Speed change control method of automatic transmission

Abstract

Abstract PURPOSE:To always properly correct the speed change control independently of the engine warming state by taking account of the oil temperature of an automatic transmission in correcting the learning control. CONSTITUTION:Into a central processing unit 104, the signal of an oil temperature sensor 120 for detecting the oil temperature of an automatic transmission and the signal of the revolution speed sensor 122 for detecting the revolution speed of a clutch C0, are input. Therefore, the speed change control can be properly corrected by correcting the speed change control of the second transmission in the next time, at least in consideration of the oil temperature on the basis of the result of the speed change timing at this time.
