Abstract
In a drive unit including a motor, an inverter, a first electric storage device, a step up-down converter, first and second capacitors, a DC-DC converter, and a relay, the DC-DC converter is driven, while a target duty ratio of the step up-down converter is set such that a total loss of the step up-down converter and the DC-DC converter becomes larger than a maximum loss value of the step up-down converter, and the step up-down converter is controlled, when the relay is turned off to discharge charge of the first capacitor and the second capacitor.
