POWER OUTPUT DEVICE, HYBRID AUTOMOBILE USING THE SAME, AND METHOD OF CONTROLLING POWER OUTPUT DEVICE

摘要

When a predetermined change speed state shift condition is satisfied while the transmission 60 connects a carrier 45 with a drive shaft 67, a hybrid vehicle 20 performs a rotational speed adjustment process of conforming a rotational speed of a motor MG1 to a target rotational speed Nm1* based on a gear ratio of the transmission 60 and a rotational speed of the drive shaft 67, a connection a sun gear 41 with the drive shaft 67 by a gear train of the transmission 60 corresponding to a target speed n*, a power transfer process of transferring power between the motors MG1 and MG2 in a simultaneous engagement state to make the motors MG1 and MG2 respectively output power required in a post-change speed state corresponding to a target speed n*, and a disconnection the carrier 45 from the drive shaft 67.
