PROBLEM TO BE SOLVED: To balance between a fuel economy improvement and an acceleration-deceleration response speed in auto-cruising of a hybrid vehicle.SOLUTION: In a hybrid vehicle 100, a clutch 15 controls power transmission of a diesel engine 10. A transmission 20 is connected to the diesel engine 10 via the clutch 15. A propeller shaft 25 transmits power of the diesel engine 10 to a drive wheel 27 via the transmission 20. A motor-generator 33 is connected to the propeller shaft 25 via a speed reduction mechanism 30. In a case where a vehicle speed falls below a set value when the hybrid vehicle 100 travels under an auto-cruise, a control apparatus 80 executes control in which to (1) cut off the clutch 15, (2) set a fuel injection amount to be supplied to the diesel engine 10 at or under a given value, and (3) cause a motor-generator 33 to power the vehicle to travel.SELECTED DRAWING: Figure 1 【課題】ハイブリッド車両のオートクルージングにおける燃費向上と加減速の応答速度とを両立させる。【解決手段】ハイブリッド車両１００において、クラッチ１５は、ディーゼルエンジン１０の動力伝達を制御する。トランスミッション２０は、クラッチ１５を介してディーゼルエンジン１０と接続される。プロペラシャフト２５は、トランスミッション２０を介してディーゼルエンジン１０の動力を駆動輪２７に伝達する。モータジェネレータ３３は、プロペラシャフト２５と減速機構３０を介して接続される。制御装置８０は、ハイブリッド車両１００がオートクルーズで走行している場合において車両速度が設定値を下回ったとき、（１）クラッチ１５を切断し、（２）ディーゼルエンジン１０に供給する燃料噴射量を所定値以下とし、かつ（３）モータジェネレータ３３を力行させる制御を実行する。【選択図】図１
