PROBLEM TO BE SOLVED: To provide a rational and efficient learning correction control by improving a memory renewal method of a correction amount data in the case of making learning corrections on an operating pressure on a friction element at speed change time. SOLUTION: A throttle opening and a learning correction amount corresponding to this opening are individually stored as one set of learning data (θ0, P0) to (θ3, P3) in a memory cell of a memory part, linear interpolation between each data is performed, to generate an approximate correction amount. When a new data (θ4, P4) or (θ5, P5) is obtained, when the usual data (θ1, P1) is positioned in the vicinity of the new data (θ4, P4), the data (θ1, P1) is eliminated to store the new data (θ4, P4) in the cell. When an error (Er2) generated between the usual data (θ2, P2) and the approximate correction amount by interpolation is small, this data (θ2, P2) is eliminated, the new data (θ5, P5) is stored in the cell. Approximate correction well following a change of a correction amount can be made by the smallest required number of data of no waste.
