A hybrid vehicle including an engine, a drive motor, a first oil pump, and a second oil pump is configured to, during forward travel, supply components to be cooled or lubricated with oil discharged from a discharge port of the first oil pump and a discharge port of the second oil pump via an oil passage, while the hybrid vehicle is configured to, during reverse travel, compensate for a driving force by supplying oil discharged from the discharge port of the second oil pump to the discharge port of the first oil pump via the oil passage to cause the first oil pump to operate as a hydraulic motor. 1. A hybrid vehicle comprising:an engine configured as a driving force source;a drive motor configured as a driving force source;a first oil pump configured to be mechanically driven by a driving force that is transmitted via an output part from at least one of the engines or the drive motor; anda second oil pump configured to be driven by a driving force from a rotational driving source, the driving force being different from a driving force that is transmitted to the output part, whereinduring forward travel of the hybrid vehicle, the hybrid vehicle travels by using at least one of the engine or the drive motor,during reverse travel of the hybrid vehicle, the hybrid vehicle uses the drive motor and travels by transmitting a driving force from the drive motor to a drive wheel via the output part, andduring forward travel of the hybrid vehicle, the hybrid vehicle is configured to supply components to be cooled or lubricated with oil discharged from a discharge port of the first oil pump and a discharge port of the second oil pump via an oil passage, while during reverse travel of the hybrid vehicle, the hybrid vehicle is configured to cause the first oil pump to operate as a hydraulic motor by supplying oil discharged from the discharge port of the second oil pump to the discharge port of the first oil pump via the oil passage.2. The hybrid vehicle according to claim 1 , ...

車両の制御装置

【課題】ピニオン温度をより高い精度で推定できるようにする。【解決手段】エンジントルクおよびエンジン回転速度の積算値であるエンジン出力Ｐe とピニオン回転速度Ｎpin とを用いてピニオン温度Ｔpin を算出するため（ＳＰ１）、ピニオン温度Ｔpin の推定精度が高くなる。これにより、そのピニオン温度Ｔpin が判断基準温度Ｔpinbase を超えた場合にピニオン回転速度Ｎpin を制限するピニオン温度調整制御（ＳＰ３〜ＳＰ７）が高い精度で適切に行なわれるようになり、ピニオン回転速度Ｎpin の制限の実施をできるだけ抑制して燃費等を確保しつつ、ピニオン温度Ｔpin が判断基準温度Ｔpinbase を超えた場合にはピニオン温度調整制御によってピニオン回転速度Ｎpin が制限され、ピニオンの過熱による耐久性低下が適切に防止される。【選択図】図３

【課題】自動運転走行中にエンジンの始動及び停止が頻繁に繰り返されることを抑制しつつ、燃費の悪化を抑制できるハイブリッド車両の制御装置を提供する。【解決手段】手動運転走行中におけるエンジン停止判定値Ｐstopは、エンジン１２の始動直後では所定のパワー値Ｐ１に設定され（ステップＳ３４）、その始動からの経過時間Ｔが所定の継続時間Ｔref以上になると所定のパワー値Ｐ２（＞Ｐ１）に設定される（ステップＳ３８）。自動運転走行中におけるエンジン停止判定値Ｐstopは、手動運転走行中におけるエンジン１２の始動直後に設定される所定のパワー値Ｐ１よりも大きい所定のパワー値Ｐ２に設定される（ステップＳ５０）。これにより、自動運転走行中におけるヒステリシス（エンジン始動判定値Ｐstartとエンジン停止判定値Ｐstopとの差）は、手動運転走行中におけるエンジン１２の始動直後のヒステリシスよりも小さく設定される。【選択図】図２
