<P>PROBLEM TO BE SOLVED: To provide a drive device for a hybrid vehicle capable of suppressing a shock generated in the drive device when rotating an output member to a prescribed direction and when changing over a drive mode. <P>SOLUTION: The drive device 2 mounted in the hybrid vehicle 1 includes: a differential mechanism 9 which is configured as a mutually differentially rotatable single pinion type planetary gear mechanism where an engine 3 and a first MG 5 are connected to a ring gear R through a clutch 10 allowing the intermittence of power transmission where a second MG 6 is connected to a sun gear S, and an output gear 8 for outputting power to drive wheels 7 of the vehicle 1 is connected to a carrier Cr positioned in the center when arranging respective rotation elements on a collinear diagram; a brake 11 capable of changing over the ring gear R between a braking state that the ring gear R cannot be rotated and a brake release state of releasing the braking state; and a controller 20 performing control so that the drive mode of the drive device 2 is changed over between a series drive mode and a series parallel drive mode according to the travel state of the vehicle 1. <P>COPYRIGHT: (C)2011,JPO&INPIT |
