HYBRID DRIVING DEVICE AND AUTOMOBILE EQIPPED THEREWITH

摘要

PROBLEM TO BE SOLVED: To solve a problem wherein a hybrid driving device becomes too large, thereby posing a problem in vehicle mounting property, when the requested driving force of an automobile is large in the hybrid driving device transmitting output of a motor for driving to a driving wheel as assist force.

SOLUTION: Output of an internal combustion engine 5 is shifted in a continuously variable manner by a planetary gear 9 for power distribution by controlling a motor 7 for control to transmit it to an output shaft 16. Output of the motor 101for driving is shifted to two speed deceleration rotation by an automatic transmission 301to input it in the output shaft 16. The transmission 301decelerates greatly when the automobile runs at low speed to obtain desired torque and decelerates by small extent when it runs at high speed to obtain desired number of revolutions.
