PROBLEM TO BE SOLVED: To resolve a problem of erroneous learning due to racing of an engine when shift points are learned and corrected on the basis of maximum engine speed. SOLUTION: In an upshift during full throttle, an actual shift start is delayed by delay of oil pressure, rise of torque capacity of a clutch or the like even when a shift judgment Us1 is outputted from a control part, and a shift start Uj is judged by comparing an input rotational frequency Ni with a value multiplying a gear ratio before shifting on an output rotational frequency (a vehicle speed) No. A shift point Mp1 is learned and corrected on the basis of a rotational frequency Ne1 at the shift start. |
