PROBLEM TO BE SOLVED: To secure a necessary oil amount while suppressing deterioration of fuel economy of an engine in a hybrid vehicle that includes both of a transmission and a power distribution device disposed between the engine and first and second rotary electric machines, and an oil pump driven by an output shaft of the transmission.SOLUTION: A vehicle 1 travels on drive force of at least any of an engine 10, and first and second MG 20, 30. A drive apparatus of the vehicle includes: a transmission 40 connected to an output shaft of the engine; a power distribution device 50 for transmitting rotation from the transmission to a drive wheel; an oil pump 62 driven by an output shaft of the transmission; and an ECU 300. In an HV travel mode, the ECU adjust a gear ratio of the transmission and a rotation speed of the first MG so as to minimize a difference between a necessary flow rate of hydraulic pressure and a flow rate ejected from the oil pump, while maintaining an operating point of the engine and a rotation speed of a drive wheel.SELECTED DRAWING: Figure 1

    【課題】エンジンと第1および第2の回転電機との間に変速装置および動力分配装置が設けられ、変速装置の出力軸により駆動されるオイルポンプを有する車両において、エンジンの燃費の悪化を抑制しつつ、必要となる油量を確保する。【解決手段】車両1は、エンジン10と、第1MG20,第2MG30の少なくともいずれかの駆動力を用いて走行する。車両の駆動装置は、エンジンの出力軸に結合される変速装置40と、変速装置からの回転を駆動輪に伝達する動力分配装置50と、変速装置の出力軸により駆動されるオイルポンプ62と、ECU300とを備える。ECUは、HV走行モードにおいて、エンジンの動作点および駆動輪の回転速度を維持しながら、必要とされる油圧の流量と、オイルポンプの吐出油量との差が小さくなるように、変速装置の変速比および第1MGの回転速度を調整する。【選択図】図1
