POWER OUTPUT DEVICE, HYBRID CAR EQUIPPED WITH THE SAME, AND CONTROL METHOD FOR POWER OUTPUT DEVICE

摘要

PROBLEM TO BE SOLVED: To improve the transmission efficiency of power between an internal combustion engine and a driving shaft by more properly connecting both first and second elements of a power distribution integration mechanism to a driving shaft 67.

SOLUTION: In a hybrid car 20, when predetermined simultaneous engagement execution conditions are established in such a state that a carrier 45 is connected to a driving shaft 67 by a transmission 60: revolving speed adjustment processing for matching the revolving speed of a motor MG1 with target revolving speed Nm1* based on the gear ratio of the transmission 60 and the revolving speed of the driving shaft 67; the connection of a sun gear 41 composed of a gear string corresponding to the target number of gear-change stage n* of the transmission 60 and the driving shaft 67; and torque adjustment processing for adjusting the output torque of the motors MG1 and MG2 so that torque cannot be substantially output by the both motors MG1 and MG2 in such a state that the carrier 45 and the sun gear 41 are connected to the driving shaft 67 are executed.
