<P>PROBLEM TO BE SOLVED: To further appropriately perform stable output of torque to a driving shaft and charge/discharge according to the characteristic of a secondary battery. <P>SOLUTION: When the battery temperature Tb of a battery having a characteristic that the chargeable maximum power is smaller than the dischargeable maximum power at a temperature lower than a predetermined temperature Tbref is a predetermined temperature Tbref or higher, a predetermined value Hisref is set as hysteresis widths Hisdown and Hisup on the charge and discharge sides (S160 and S180). When the battery temperature Tb is lower than the predetermined temperature Tbref, the predetermined value Hisref is set as the hysteresis width Hisdown on the charge side, and a value smaller than the predetermined value Hisref is set as the hysteresis width Hisup on the discharge side (S160 and S190), and temporary output Pm1 of the first motor is set and temporary torque Tm2tmp of the second motor is restricted (S200 to S230) so as to perform holding as much as possible in a large range by the hysteresis widths Hisdown and Hisup on the charge and discharge sides for a target output Pm1 of the first motor. <P>COPYRIGHT: (C)2010,JPO&INPIT |
