Abstract
When a predetermined change speed state shift condition is satisfied while the transmission connects a carrier with a drive shaft, a hybrid vehicle performs a rotational speed adjustment process of conforming a rotational speed of a motor to a target rotational speed based on a gear ratio of the transmission and a rotational speed of the drive shaft, a connection a sun gear with the drive shaft by a gear train of the transmission corresponding to a target speed, a power transfer process of transferring power between the motors in a simultaneous engagement state to make the motors output power required in a post-change speed state corresponding to a target speed, and a disconnection the carrier from the drive shaft.
