Abstract
A hybrid vehicle 20 of the invention is equipped with a power distribution integration mechanism 40 and a transmission 60. The power distribution integration mechanism 40 is a double pinion planetary gear mechanism constructed to include a carrier 45 connecting with a motor MG2, a sun gear 41 connecting with a motor MG1, and a ring gear 42 connecting with an engine 22 and to have a gear ratio of approximately 0.5. The transmission 60 includes a three element-type first change speed planetary gear mechanism PG1, a three element-type second change speed planetary gear mechanism PG2, a brake clutch BC1 configured to fix a ring gear 62 of the first change speed planetary gear mechanism PG1 in a non-rotatable manner and release the ring gear 62 in a rotatable manner, and a brake clutch BC2 configured to enable and disable power transmission via the second change speed planetary gear mechanism PG2.
