To suppress a distance or time for allowing a travel on electric power from being shortened when such travel is instructed.SOLUTION: In the case of parking at a given spot being predicted, charging ratio reduction control is executed to control an engine and a motor so as to reduce a charging ratio of a battery comparably with the case of parking at the given spot being not predicted in the current trip, and charging ratio recovery control is executed to control the engine and motor so that the charging ratio of the battery recovers when the engine is operated, in the next trip. Further, in the case of a travel on electric power, that is, a trip without operating the engine, being predicted to be instructed once the next trip is started at a given spot, even in the case of parking at the given spot being predicted, the execution of the charging ratio reduction control is limited in the current trip.SELECTED DRAWING: Figure 3 【課題】電動走行が指示されたときに、電動走行可能な距離や時間が短くなるのを抑制する。【解決手段】所定地点での駐車が予測されるときには、今回のトリップで、所定地点での駐車が予測されないときよりも蓄電装置の蓄電割合が低くなるようにエンジンおよびモータを制御する蓄電割合低下制御を実行すると共に、次回のトリップで、エンジンの運転時に蓄電装置の蓄電割合が回復するようにエンジンおよびモータを制御する蓄電割合回復制御を実行する。そして、所定地点での駐車が予測されるときでも、所定地点で次回にトリップを開始するとトリップの開始から所定期間内または所定距離内にエンジンの運転を伴わずに走行する電動走行が指示されると予測されるときには、今回のトリップでの蓄電割合低下制御の実行を制限する。【選択図】図３
