Beschreibung
Zusammenfassung:	In a hybrid vehicle driving apparatus having an input shaft connected to an engine, an output shaft connected to wheels, a first planetary gear mechanism whose sun gear is connected to the input shaft, a second planetary gear mechanism whose carrier is connected to the input shaft, a mechanism reducing rotation speed of the input shaft and transmit to the first planetary gear mechanism carrier, a clutch connecting/disconnecting the first planetary gear mechanism carrier and the second planetary gear mechanism sun gear, and a clutch connecting/disconnecting ring gears of the first and second planetary gear mechanisms, the second planetary gear mechanism ring gear is connected to the output shaft and an electric rotating machine is connected to the first planetary gear mechanism carrier, thereby enabling a vehicle to run only with the engine, while improving the operation efficiency on the high ratio side.
