Abstract
The electric motor vehicle includes a voltage conversion circuit, a primary-side smoothing capacitor, a battery, a system main relay, an inverter circuit, a secondary-side smoothing capacitor, an electric motor, a first voltage sensor, a collision sensor, and a controller. The controller is configured to adjust an operation of the voltage conversion circuit, detect primary-side voltage by using the first voltage sensor in a state that the voltage conversion circuit is operated in a case where a collision is detected by the collision sensor, and detect a state that the system main relay is off based on a change in the detected primary-side voltage.
