PROBLEM TO BE SOLVED: To surely provide an acceleration feeling expected by a driver and easily and quickly perform tuning for every type of vehicles by setting a prescribed value less than a target input shaft rotational speed as a shift rotational speed based on a driving state and fixedly controlling a target change gear ratio to a prescribed value, when the practical target input shaft rotational speed exceeds the prescribed value. SOLUTION: When a vehicle travels at a vehicle speed VSPx, a throttle opening VTO=0/8, and a target input shaft rotational speed N1, an accelerator pedal is stepped to the whole opening position, in reaching the throttle opening=8/8, the increasing step shifting is judged, a shift change rotation speed N2 shifted from the preset tNt limit line is decided, and the hold change gear ratio RTOHOLD is decided. The vehicle smoothly moves from N1 to N2 at the practical target input shaft rotational speed RREV while preventing the initial shift shock, the hold change gear ratio is held after that, and the vehicle speed is linearly increased till the target input shaft rotational speed N3 according to the throttle opening 8/8. |
