Zusammenfassung:	To improve energy efficiency of a vehicle.SOLUTION: An engine, a motor, and a clutch are controlled so as to travel on the basis of a travel required power, required for traveling, while switching between a hybrid travel mode for traveling with a clutch on and with an operation of an engine involved and an electric travel mode for traveling with the clutch off and with an operation of the engine stopped. In this case, in the hybrid travel mode, if the engine speed is within a predetermined speed range in which the engine can be efficiently operated, the hybrid travel mode is continued; and if the engine speed is outside the predetermined speed, switching to the electric travel mode is performed.SELECTED DRAWING: Figure 2 【課題】車両のエネルギ効率を良好にする。【解決手段】クラッチがオンで且つエンジンの運転を伴って走行するハイブリッド走行モードと、クラッチがオフで且つエンジンの運転停止を伴って走行する電動走行モードとを切り替えながら、走行に要求される走行要求パワーに基づいて走行するように、エンジンとモータとクラッチとを制御する。この場合に、ハイブリッド走行モードであるときにおいて、エンジンの回転数がエンジンを効率よく運転可能であるとして予め設定された所定回転数範囲内であるときには、ハイブリッド走行モードを継続し、エンジンの回転数が所定回転数範囲外であるときには、電動走行モードに切り替える。【選択図】図２
