Zusammenfassung:PROBLEM TO BE SOLVED: To enable a vehicle to smoothly accelerate even if target torque is rapidly increased, furthermore, to adjust output torque of an internal combustion engine accurately, and to suitably suppress vibration in a vehicle drive system.SOLUTION: An output of an accelerator pedal is supplied as correction target torque to a throttle via a first filter processing part for suppressing vibration in a vehicle drive system and a second filter processing part for expressing a response delay of the internal combustion engine. In addition, estimation torque is evaluated based on a throttle opening, a deviation is evaluated between the estimation torque and the correction target torque, actual torque is corrected to cancel the deviation, and the correction target torque has a desired effect. 【課題】目標トルクを急激に増大させた場合でも、円滑に車両を加速可能とし、しかも内燃機関の出力トルクを正確に調整し、車両駆動系の振動を好適に抑制する。【解決手段】アクセルペダルの出力を、前記車両駆動系の振動を抑制する第1のフィルタ処理部及び前記内燃機関の応答遅れを表現する第2のフィルタ処理部を介して、補正目標トルクとしてスロットルに供給する。更に、スロットル開度に基づく予測トルクを求め、予測トルクと補正目標トルクとの間の偏差を求め、該偏差を解消するように実トルクを補正し、補正目標トルクが、想定通りの効果を生じさせるようにする。【選択図】図3
