Abstract
In the presence of a torque change request (step S) for changing a torque Tmof one motor MGto enable a smooth gearshift of a transmission interposed between a motor and a driveshaft, when the change of the torque Tmis unattainable within the range of an input limit Win and an output limit Wout of a battery (step S), the power output apparatus of the invention resets a torque command Tm* of the other motor MGto be within the input limit Win and the output limit Wout of the battery (steps Sand S). The power output apparatus also resets an engine power demand Pe* to make a rotation speed Ne of an engine approximately equal to a target rotation speed Ne* (steps Sand S). This arrangement ensures a smooth gearshift of the transmission.
