When a boost converter has an abnormality, a battery-less traveling is executed by shutting off a gate of the boost converter and setting a voltage command VH* of a capacitor (high-voltage-system electric power line) to a predetermined voltage VHset higher than a battery voltage VB. Then, during the execution of the battery-less traveling, when it is determined that a charging current has flowed through a battery or when it is determined that the voltage (high-voltage-system voltage) VH of the capacitor has approached the battery voltage VB, it is determined that an upper arm of the boost converter has been short-circuited.
