<P>PROBLEM TO BE SOLVED: To provide a hybrid drive device capable of improving power transmission efficiency and fuel consumption, and simplifying the configuration. <P>SOLUTION: The hybrid drive device is equipped with two sets of planetary gear mechanisms 4, 5 which have three rotation elements performing a differential operation, and at least three engagement devices CM, CH, BL switching the route transmitting the power to an output member 14 through the two sets of planetary gear mechanisms 4, 5. The hybrid drive device is constituted that not less than three kinds of power transmission route wherein an interrelationship of the operation state between a first electric motor 2 and a second electric motor 3 for setting the ratio of the number of revolution between an internal combustion engine 1 and the output member 14 to a predetermined value is different depending on the engaging state and the releasing state of the three engagement devices. <P>COPYRIGHT: (C)2007,JPO&INPIT |
