前記第1回転電機の動力による前記ハイブリッド車両の走行中、前記要求駆動力が0以下のときの前記内燃機関の回転数を、前記ハイブリッド車両の走行速度に基づいた前記走行速度が大きいほど高い可変な所定値に保持し、前記要求駆動力が0よりも大きくなった場合には、前記要求駆動力に応じた回転数よりも前記所定値が低い場合に、前記内燃機関の回転数を、前記所定値に保持されていた回転数から、前記要求駆動力に応じた回転数まで上げるよう制御するハイブリッド車両である。
前記制御部は、前記内燃機関の動力によって前記第2回転電機が発電した電力が供給される前記第1回転電機の動力による前記ハイブリッド車両の走行中、前記要求駆動力が0以下のときの前記内燃機関の回転数を前記所定値に保持する。
前記内燃機関と前記出力軸との間の動力の伝達経路を断接する断接部(例えば、後述の実施形態でのロックアップクラッチCL)を備え、
前記所定値は、前記断接部を締結した状態で前記ハイブリッド車両が走行する場合の、前記内燃機関の回転数以下の値である。
前記所定値は、前記内燃機関のアイドリング動作時の回転数より高い値である。
前記制御部は、前記内燃機関の回転数を前記所定値に保持するよう制御しているときは、前記内燃機関の動力によって前記第2回転電機が発電を行うよう制御する。

前記蓄電器に入力される電力の制限値を超えない範囲で前記第2回転電機が発電を行うよう制御する。
前記制御部は、前記内燃機関の回転数を前記所定値に保持するよう制御した状態での前記蓄電器に入力される電力が前記制限値を超える場合は、前記回転数を前記所定値に保持したまま前記内燃機関のトルクを低減する。
前記内燃機関の回転数が前記所定値となるよう制御された状態で前記ハイブリッド車両が坂道を走行する場合の前記所定値は、前記坂道の勾配に応じた可変な値である。
前記坂道が登坂路である場合、前記所定値は、前記登坂路の勾配が大きいほど高い値である。
図1に示した車両は、図5に示すように、典型的に以下の走行モードを有している。
EV走行モードに設定された車両では、クラッチCLは開放され、内燃機関ENGは停止している。車両は、蓄電器BATからの電力供給によって駆動する第1回転電機MG1の動力によって走行する。
シリーズ走行モードに設定された車両では、クラッチCLは開放され、内燃機関ENGは運転している。車両は、蓄電器BATからの電力供給と共に、内燃機関ENGの運転によって第2回転電機MG2が発電した電力が供給される第1回転電機MG1の動力によって走行する。
エンジン走行モードに設定された車両では、クラッチCLは締結され、内燃機関ENGは運転している。車両は、内燃機関ENGが出力した動力によって走行する。なお、エンジン走行モードでの走行時、第1回転電機MG1及び第2回転電機MG2の各回転子は、内燃機関ENGの駆動と共に連れ回される。但し、ECU107は、第1回転電機MG1及び第2回転電機MG2がそれぞれ無負荷状態となるようゼロトルク制御を行う。
