Zusammenfassung:	PROBLEM TO BE SOLVED: To suppress the over-discharges of each electric storage device more properly while preventing the overlimiting of output from a motor, in a power output unit including the motor and a plurality of electric storage devices. SOLUTION: When both battery temperatures Tbm and Tbs are a reference temperature Tref or higher, the sum of an output limit Woutm and the output limit Wouts is set in a total output limit Wout (S330). Either one of the battery temperatures Tbm and Tbs is less than the reference temperature Tref while the output limit Wouts is replaced with a target slave power Pbs* determined from a total demand power Ptotal and a power shared rate R* for operating an engine 22, and the total output limit Wout is set in this case (S420). Torque commands Tm1* and Tm2* are corrected so that the powers input and output to and from the motors MG1 and MG2 are kept within the ranges of a total input limit Win and the total output limit Wout (S340 to S370).
