To provide a vehicle control device which can properly suppress stopping at a high position of a rotation speed of an internal combustion engine during series travel.SOLUTION: A control device 100 can execute fuel cut control of stopping fuel supply to an engine ENG. The control device 100 controls a rotation speed (engine rotation speed) of the engine ENG to a predetermined target rotation speed on the basis of the travel state of a vehicle 1 when the vehicle 1 performs so-called series traveling. Specifically, the control device 100 controls the engine rotation speed Ne10 to a target rotation speed Ne_tar when the vehicle 1 performs series traveling and there is a deceleration request, and executes fuel cut control according to a rotation speed difference between the engine rotation number Ne10 and the target rotation number Ne_tar.SELECTED DRAWING: Figure 5 【課題】シリーズ走行中の内燃機関の回転数の高止まりを適切に抑制可能な車両の制御装置を提供する。【解決手段】制御装置１００は、エンジンＥＮＧへの燃料供給を停止する燃料カット制御を実行可能である。制御装置１００は、車両１がいわゆるシリーズ走行しているときに、車両１の走行状態に基づき、エンジンＥＮＧの回転数（エンジン回転数）が所定の目標回転数となるように制御する。具体的に、制御装置１００は、車両１がシリーズ走行しており、且つ減速要求があるときには、そのときのエンジン回転数Ｎｅ１０が目標回転数Ｎｅ＿ｔａｒとなるように制御し、エンジン回転数Ｎｅ１０と目標回転数Ｎｅ＿ｔａｒとの回転数差に応じて燃料カット制御を実行する。【選択図】図５
