The vehicle drive device is configured with an input shaft coupled to an engine, a rotary electric machine, and an output shaft coupled to wheels. A power transfer mechanism couples input shaft, the rotary electric machine, and the output shaft. A case houses at least the rotary electric machine and the power transfer mechanism. An oil reserving portion capable of reserving oil supplied by rotation of the power transfer mechanism is provided above the rotor shaft inside the case. A communication oil passage is oriented between the oil reserving portion and an inner circumferential space formed inside the rotor shaft. The rotor shaft is disposed to be inserted into the inside housing space, and has a supply communication hole that communicates between the inner circumferential space and the inside housing space.

摘要： A control system for an automatic transmission, comprising a gear transmission unit for establishing a predetermined gear stage by applying a plurality of frictional engagement elements selectively. The gear transmission unit includes a main transmission portion capable of establishing at least a reverse gear stage, and an auxiliary transmission portion capable of switching a high gear stage and a low gear stage. The auxiliary transmission portion is set to the high stage at the shifting time to the reverse stage. The reverse stage is established by controlling the application of predetermined frictional engagement elements of the main transmission portion when a reverse stage shifting command is generated. A torque-down of an engine is executed at the time of controlling the engagement of the frictional engagement elements for the reverse stage. The auxiliary transmission portion is set to the high stage by controlling the applications of predetermined frictional engagement elements of the auxiliary transmission portion when the reverse stage in the main transmission portion is detected. A signal to end the engine torque-down is sent when a shift of the auxiliary transmission portion to the high stage is detected.
