A drive apparatus is for a vehicle that includes left and right wheels. The drive apparatus includes: (a) a left-side gear transmission mechanism disposed between a left-side drive source and the left wheel; and (b) a right-side gear transmission mechanism disposed between a right-side drive source and the right wheel. Each of the left-side and right-side gear transmission mechanisms includes a plurality of rotary shafts and a plurality of gears. The left-side and right-side gear transmission mechanisms are the same as each other in terms of a number of the rotary shafts, a number of the gears and a positional relationship between the gears. Each of the gears of the left-side gear transmission mechanism and a corresponding one of the gears of the right-side gear transmission mechanism are identical with each other and disposed in the same attitude as each other.

Drive apparatus for vehicle

A vehicle electric drive apparatus is provided with a single hydraulic pump and left-side and right-side drive units. The left-side drive unit includes a left-side electric motor and a left-side transmission mechanism. The right-side drive unit includes a right-side electric motor and a right-side transmission mechanism. One of rotary shafts of the left-side transmission mechanism and one of rotary shafts of the right-side transmission mechanism constitute a pair of pump-drive rotary shafts. The single hydraulic pump is connected to the pair of pump-drive rotary shafts through respective one-way clutches, and is to be driven by one of the pump-drive rotary shafts that is rotated at a speed higher than the other of the pump-drive rotary shafts, so as to output a hydraulic pressure.

Electric drive apparatus for vehicle

A drive control device for a hybrid vehicle is provided with a differential device including four rotary elements; and an engine, first and second electric motors and an output rotary member which are respectively connected to the four rotary elements. One of the four rotary elements is constituted by a rotary component of a first differential mechanism and a rotary component of a second differential mechanism selectively connected through a clutch, and one of the rotary components of the first and second differential mechanisms which are selectively connected to each other through the clutch is selectively fixed to a stationary member through a brake. The drive control device comprises: an electric motor operation control portion configured to control the second electric motor for starting the engine with an output torque of the second electric motor, when a reaction force is exerted on the first and second electric motors.
