Abstract
A smoothing capacitor is forcibly discharged, in a state where a battery is disconnected from a high-voltage circuit, first discharge control is initiated to consume electric charges of the smoothing capacitor by an in-vehicle component via a DC/DC converter. Thereafter, when a voltage of the smoothing capacitor is reduced and reaches a specified threshold, second discharge control is executed to forcibly discharge the electric charges in an active discharge circuit. In the case where continuous forced discharge occurs, delay control to delay execution timing of the second discharge control is further executed.
