PURPOSE:To accelerate a car in consideration of smoothness at the time of acceleration in a high-speed area and improve acceleration feeling by correcting the shift speed with the decreasing function for the throttle opening change speed indicating the acceleration request of a driver and also with the decreasing function for the car speed. CONSTITUTION:In the speed change control at the time of acceleration, the target change gear ratio is when an accelerator is depressed is set on the low- speed stage side, and the down-shift is performed so that the actual change gear ratio (i) follows it. The throttle opening change speed theta' and the car speed are inputted to a correction coefficient setting unit 60 based on the throttle opening theta to determine the correction coefficient K1. The correction coefficient K1 is decreased and the change gear speed is decreased as the car speed is increased and the throttle opening change speed is increased. The smooth acceleration performance so that the engine rotating speed is increased together with the car speed is obtained, and the feeling with no unnecessary slip sense is obtained. |
