A second control unit performs a switching control task of repeatedly switching between an on state and an off state of an upper-arm switching device of a voltage converter in response to determination that a monitored terminal voltage across a smoothing capacitor is not lower than or equal to an anomaly determination threshold during failure of a first control unit. The second control unit determines whether the switching control task causes the monitored terminal voltage across the smoothing capacitor to be lower than or equal to the anomaly determination threshold. The second control unit controls, in response to determination that the switching control task causes the monitored terminal voltage across the smoothing capacitor to be lower than or equal to the anomaly determination threshold, at least one motor-generator to perform a limp-home control task of the electric vehicle.
