PROBLEM TO BE SOLVED: To prevent battery voltage from easily reaching below an acceptable lower limit voltage for control.SOLUTION: When warming of purifying catalyst is demanded and the driving power Pdrv* is larger than output limit for control Wout* of high voltage battery, difference power (Pdrv*-Wout*) derived by subtracting the output limit for control Wout* from the driving power Pdrv* is output from an engine, and the engine and a motor are controlled so that a vehicle is driven by the driving power Pdrv*. In case the inter-terminal voltage Vb of the high voltage battery is not higher than a threshold voltage Vbref which is higher than an acceptable lower limit voltage Vbmin (S320), a control current limit Ibmax* and the output limit for control Wout* are made smaller than these before the inter-terminal voltage Vb of high voltage battery is not higher than the threshold voltage Vbref (S360, S370). |
