Abstract
An electronic control unit includes a first calculator and a second calculator. When the first calculator has an abnormality, even if a start switch of a vehicle is switched OFF by a driver of the vehicle, the second calculator is configured to maintain system main relays on a positive terminal side and a negative terminal side in a conductive state in case that a certain travel continuation condition is fulfilled. Therefore, even when the driver has erroneously switched OFF the start switch, an electric power is suppliable to an inverter via the system main relays kept in the conductive state, thereby the vehicle is travelable by using a vehicle travel-power motor.
