Abstract: A vehicle control device mounted on a vehicle includes a first traveling mode being driven by the torque output from a first rotary electric machine, and a second traveling mode being driven by the engine torque output from an engine and the torque output from the first rotary electric machine, wherein a section 1 for cranking the engine by the output of the second rotary electric machine and a section 2 for assisting the driving force of the engine by the output of the first rotary electric machine are provided during a period from the first traveling mode to the engagement of the clutch at the time of starting the engine to the second traveling mode, and the torque increase of the first rotary electric machine is limited in the section 1.

Abstract: The power transmission apparatus includes: a gear chamber, used for accommodating gears disposed on a rotating shaft used for transmitting power to a drive wheel; a clutch chamber, disposed adjacent to the gear chamber in an axial direction of the rotating shaft, and used for accommodating a clutch used for disconnecting or connecting the power transmitted by the rotating shaft to the drive wheel; and a communicating hole, used for communicating the clutch chamber with the gear chamber, where an inclined surface facing toward the communicating hole is provided on an inner surface inside the clutch chamber opposite to an outer peripheral surface of the clutch.

Abstract: The power transmission apparatus is a power transmission apparatus mounted on a vehicle. A gear chamber includes a gear accommodating portion used for accommodating a gear and a strainer accommodating portion used for accommodating an oil strainer. The gear accommodating portion and the strainer accommodating portion are disposed abreast in an axial direction. One clutch chamber of a pair of clutch chambers adjacent to the strainer accommodating portion only directly communicates with the strainer accommodating portion of the gear accommodating portion and the strainer accommodating portion, and the one clutch chamber communicates with the gear accommodating portion only by using the strainer accommodating portion.
