PROBLEM TO BE SOLVED: To provide a hybrid vehicle and a control method therefor such that while regeneration efficiency in a high speed travel is improved as compared with the conventional art, a fuel consumption is reduced so as to improve fuel economy without stopping a steering assist in an auto-cruising mode and while keeping a charged state of a battery within a proper range.SOLUTION: A hybrid vehicle comprises a speed reduction mechanism 30 which connects a propeller shaft 25 to a rotary shaft 32 of a motor generator 33 and a driving shaft 46 of a second power steering pump 45 respectively, and a switching device which switches a supply source for a power steering fluid to a steering unit 53 to the second power steering pump 45, and a controller 80 is configured to perform control to transmit driving force to the propeller shaft 25 via the speed reduction mechanism 30 by driving and rotating a motor generator 33 when a clutch 15 is placed in a disconnected state during an engine travel and a transmission 20 is placed in an automatic speed change mode for a travel on a steep uphill road L1.SELECTED DRAWING: Figure 1

    【課題】従来よりも高速走行時における回生効率を向上しつつ、オートクルーズモードにおける操舵アシストを停止することなく、かつバッテリーの充電状態を適正範囲に維持しながら燃料消費量を削減して燃費を向上するハイブリッド車両及びその制御方法を提供する。【解決手段】プロペラシャフト25をモータージェネレーター33の回転軸32及び第2パワステポンプ45の駆動軸46のそれぞれに接続する減速機構30と、ステアリングユニット53へのパワステフルードの供給源を第2パワステポンプ45に切り換える切換装置とを備え、制御装置80を、急登坂路L1を走行する場合に、エンジン走行中にクラッチ15を切断状態にしてトランスミッション20を自動変速しているときに、モータージェネレーター33を回転駆動して、減速機構30を経由してプロペラシャフト25に駆動力を伝達する制御を行う構成にした。【選択図】図1
