PURPOSE:To obtain good driving performance and drive feeling when a vehicle is accelerated and decelerated, by setting a step change rate at deceleration to a value larger than that of the step change rate at acceleration. CONSTITUTION:A step change rate B at deceleration is set to a value larger than that of the step change rate B at acceleration. In this way, an acceleration response characteristic and acceleration feeling of a vehicle, when it is accelerated, are improved by prompt appearance of torque accelerating the vehicle without causing any necessity for largely accelerating the input side member of a CVT and moment of inertia of an engine because an actual engine speed Ne quickly reaches the target engine speed No. While good drive feeling of the vehicle, when it is decelerated, is obtained by the quick follow-up action of the actual engine speed Ne to a large decrese of the target engine speed No because of no necessity for accelerating the moment of inertia in the input side. |
