发明名称 CONTROL DEVICE OF AUTOMATIC TRANSMISSION
摘要 PROBLEM TO BE SOLVED: To provide a control device of an automatic transmission capable of learning and controlling the control oil pressure for each speed to be an optimal value quickly. SOLUTION: An oil pressure learned value setting part 52 is composed of a by-speed oil pressure learned value setting part 54 and a by-element oil pressure learned value setting part 55. When speed-changing motion is performed by engaging/disengaging friction engaging elements contributing to a plurality of speed-changing motions, the by-speed oil pressure learned value LRN is set peculiar to each speed-changing motion and the speed-changing motion using the same friction engagement element as the friction engagement element for the speed-changing motion, and in addition, the by-element oil pressure learned value PL is set peculiar to the friction engagement element contributing to the speed-changing motion. In each speed-changing motion, the control oil pressure is set by correcting the base oil pressure of the target element with the by-speed oil pressure learned value and the by-element oil pressure learned value.
