Abstract
Proper control is performed even during a stuck abnormality of a current sensorconfigured to detect a reactor current. A boosting converteris controlled by feedback control of a boosted voltage of the boosting converterand a reactor current, detected by the current sensor, of a reactorin the boosting converter. When a variation of the reactor current is less than a predetermined current value, failure determination of the current sensor is performed and, if a variation of the pre-boosting voltage exceeds a predetermined voltage value, failure of the current sensor is determined.
