摘要： PROBLEM TO BE SOLVED: To appropriately learn a command oil pressure applied to the lockup clutch in the case where reduction in engine rotation speed due to lockup clutch engagement and change in engine rotation speed due to gear change occur at the same time. SOLUTION: The control device of an automatic transmission is provided with a command oil pressure learning means (S7) for learning a command oil pressure at the time of the next engagement of the lockup clutch based on changes in the input-side rotation speed of the torque converter at the time of the present engagement of the lockup clutch, wherein the command oil pressure learning means (S7) learns the next command oil pressure based on a slip rotation speed that is a difference in rotation speed between the input-side rotation speed and output-side rotation speed of the torque converter after the start of the inertia phase when the inertia phase of the upshift of the transmission starts during the engagement of the lockup clutch.
