To appropriately adjust a rotation speed of an engine by feedback-controlling output torque of a rotating machine, while improving supercharging responsiveness until supercharging pressure rises up to a target value.SOLUTION: When MG1 torque Tg is controlled by feedback-control so that engine rotation speed Ne is equal to target engine rotation speed Netgt, FB gain K is set to a larger value when the target supercharging pressure Pchgtgt is high than when the pressure is low. This enables a control device to deal with a situation where responsiveness of engine torque Te is raised by rising of the supercharging pressure Pchg up to the target supercharging pressure Pchgtgt, while improving followability of the engine rotation speed Ne to the target engine rotation speed Netgt in a period of time until the supercharging pressure Pchg rises up to the target supercharging pressure Pchgtgt.SELECTED DRAWING: Figure 8
【課題】過給圧が目標値へ立ち上がるまでの過給応答性を向上させつつ、回転機の出力トルクのフィードバック制御によりエンジンの回転速度を目標回転速度に適切に調整する。【解決手段】エンジン回転速度Neが目標エンジン回転速度Netgtとなるようにフィードバック制御によりMG1トルクTgが制御されるに際して、目標過給圧Pchgtgtが高いときには低いときに比べてFBゲインKが大きな値に設定されるので、過給圧Pchgが目標過給圧Pchgtgtへ立ち上がるまでの間のエンジン回転速度Neの目標エンジン回転速度Netgtに対する追従性を向上しつつ、過給圧Pchgが目標過給圧Pchgtgtへ立ち上がることによってエンジントルクTeの応答性が上がることにも対応が可能となる。【選択図】図8
