PROBLEM TO BE SOLVED: To appropriately control a driving force without delay and improve acceleration feeling at a time of acceleration in a hybrid electric vehicle (HV), an electric vehicle (EV), a fuel-cell vehicle (FCV) or the like.SOLUTION: A vehicle control ECU 100 calculates a target driving force using a map on the basis of an acceleration opening and a vehicle velocity and outputs a command to a MG control ECU and an engine ECU. If the acceleration opening is constant and a vehicle acceleration peaks, the vehicle control ECU 100 suppresses excessive decrease in acceleration by calculating a subsequent target driving force on the basis of not the map but a motion equation of a vehicle. 【課題】ハイブリッド自動車（ＨＶ）や電気自動車（ＥＶ）、燃料電池車（ＦＣＶ）等において、遅れを生じることなく駆動力を適切に制御して加速時における加速フィーリング(加速感)を向上させる。【解決手段】車両制御ＥＣＵ１００は、アクセル開度及び車速に基づき、マップを用いて目標駆動力を算出してＭＧ制御ＥＣＵ及びエンジンＥＣＵに指令を出力する。車両制御ＥＣＵ１００は、アクセル開度が一定であり、かつ、車両加速度がピークに達した場合に、それ以降の目標駆動力をマップではなく、当該車両の運動方程式に基づいて算出することで加速度の過大な減少を抑制する。【選択図】図１
