POWER OUTPUT DEVICE, HYBRID VEHICLE, AND METHOD OF CONTROLLING THEM

摘要

A power output device, wherein an engine (150), a motor (130), and a motor (140) and an axle (116) are connected to a planetary carrier (123) of a planetary gear (120), a sun gear (121), and a ring gear (122), respectively, a clutch (160) is provided between the planetary gear (120) and the motor (140) so that both of them can be disengaged and engaged, a brake (162) is provided to fix the ring gear (122) when the clutch (160) is disengaged, whereby, when the clutch (160) is engaged, the formation of a parallel hybrid vehicle is realized and, when the clutch (160) is disengaged and the ring gear (122) is fixed by the brake (162), the formation of a series hybrid vehicle is realized, and the mode is switched according to the traveling conditions of the vehicle so that a traveling can be performed making use of the advantages of each mode.
