When an abnormality except for a temperature abnormality of a travel-purpose battery 220 is detected (YES in S1100), a battery ECU 260 of the present invention renders a system main relay 640 OFF to make a change to a battery-less travel mode while using a battery cooling fan 220D to cool the travel-purpose battery 220 (S1200-S 1400). When a temperature abnormality of the travel-purpose battery 220 is still detected (YES in S1600), a system-off command signal is output (S 1700) to cause the hybrid vehicle to become unable to travel. In this way, limp home mode and system shutoff of the hybrid vehicle can be surely implemented even in the case where an abnormality occurs to the travel-purpose battery 220. |
