Title:
HYBRID DRIVING DEVICE
Document Type and Number:
Japanese Patent JP2009166793
Kind Code:
A
Abstract:

To provide a hybrid driving device excellent in installation characteristics to a vehicle, capable of improving fuel consumption by reducing a reverse power running of an electric motor.

The hybrid driving device 10 includes an electric differential portion 20 for controlling a differential condition between an input shaft rotational speed and an output shaft rotational speed by controlling a driving condition of a first electric motor MG1 coupled to a reaction force element, and a second electric motor MG2 coupled so as to transmit power to a power transmission path from an output element R0 of the electric differential portion 20 to a wheel 18 through a planetary-gear-type automatic transmission mechanism 22 having two or more speed gears of different transmission ratios. The hybrid driving device 10 includes a power intermitting mechanism C1 for coupling an idle element CA0 in a state where the gear stage of the smallest transmission ratio is established in the planetary-gear-type automatic transmission mechanism 22 and an input shaft of the electric differential portion 20 so as to transmit power.
