PROBLEM TO BE SOLVED: To provide a control device of a vehicle that can reduce a feeling of strangeness experienced by a driver or suppress decrease in a fuel efficiency when correcting output required amounts to be used for speed control of a continuously variable transmission.SOLUTION: When throttle aperture tapsh for transmission gear ratio control is corrected according to auxiliary machine load torque Taux, engine rotation speed Ne is not changed rapidly by annealing processing for changing throttle aperture correction amounts Δtap during correction for increasing throttle aperture tapshc for post-correction transmission gear ratio control at which engine rotation speed Ne is increased, so that a feeling of strangeness experienced by a driver can be reduced. Further, since the correction for increasing the throttle aperture at which the engine rotation speed Ne is decreased does not lead to a feeling of acceleration, so as to hardly cause the driver to feel strangeness, during the correction for decreasing the throttle aperture tapshc for the post-correction transmission gear ratio control, an engine operation point PE can be changed promptly by skipping the annealing processing so as to suppress deterioration in a fuel efficiency.SELECTED DRAWING: Figure 7 【課題】無段変速機の変速制御に用いる出力要求量を補機負荷トルクに応じて補正する際に、運転者の違和感を低減することができ、又、燃費低下を抑制することができる車両の制御装置を提供する。【解決手段】変速比制御用スロットル開度tapshを補機負荷トルクＴauxに応じて補正する際に、エンジン回転速度Ｎeが上昇する側となる、補正後変速比制御用スロットル開度tapshcを増加させる補正時は、スロットル開度補正量Δtapの変化のなまし処理によりエンジン回転速度Ｎeが急変しないので、運転者の違和感を低減することができる。又、エンジン回転速度Ｎeが低下する側となる補正は加速感に繋がらず運転者に違和感を生じさせ難いことから、補正後変速比制御用スロットル開度tapshcを減少させる補正時は、上記なまし処理を不実施とすることでエンジン動作点ＰＥを早期に変更することができ、燃費低下を抑制することができる。【選択図】図７
