Abstract

A vehicle drive device includes an engine configured to be mounted to a vehicle, a drive shaft mechanically connected to the engine as to drive the vehicle, a first power connecting-disconnecting unit connected to one of the drive shaft and the engine, a motor generator mechanically connected to the one of the drive shaft and the engine via the first power connecting-disconnecting unit, a second power connecting-disconnecting unit connected to the motor generator, and a supercharger mechanically connected to the motor generator via the second power connecting-disconnecting unit. The vehicle drive device can retrieve regenerative electric power efficiently.

Claims (13)

1. A vehicle drive device comprising:

an engine configured to be mounted to a vehicle;

a transmission mechanically connected to a first side of the engine;

a drive shaft mechanically connected to the engine via the transmission to drive the vehicle;

a first power connecting-disconnecting unit mechanically connected to a second side of the engine, the second side of the engine being opposite to the first side of the engine;

a motor generator mechanically connected to the second side of the engine via the first power connecting-disconnecting unit;

a second power connecting-disconnecting unit connected to the motor generator;

a supercharger mechanically connected to the motor generator via the second power connecting-disconnecting unit; and

a controller electrically connected to the motor generator and the second power connecting-disconnecting unit,

wherein the first power connecting-disconnecting unit comprises a directional power transmission unit including a one-way clutch or a two-way clutch for transmitting power only to the motor generator from the second side of the engine, and

wherein the controller is configured to:

when the vehicle is decelerated or when electric power is generated by the engine while the vehicle is stopped, disengage the second power connecting-disconnecting unit and allow the motor generator to perform regeneration; and

when the engine is supercharged, engage the second power connecting-disconnecting unit and allow the motor generator to perform power running.
