It becomes possible to monitor a driven state of each wheel in a wheelchair whose wheels are driven according to output information calculated based on input information. A left wheel controller and a right wheel controller are provided. The presence or absence of a drive abnormality of the left wheel is determined by the right wheel controller receiving first drive related information that is related to a drive of the left wheel and transmitted from the left wheel controller, and the presence or absence of a drive abnormality of the left wheel is determined by the left wheel controller receiving second drive related information that is related to a drive of the right wheel and transmitted from the right wheel controller.

An ECU of a vehicle performs diagnosis processing for diagnosing whether or not a charge relay has stuck after end of charging of a power storage. When the diagnosis processing has not normally ended, the ECU requests connection again of a connector to a charge port for performing re-diagnosis processing for diagnosing again whether or not the charge relay has stuck. When the connector and the charge port are connected to each other again, the ECU determines whether or not it has received a charging start signal from a DC power feed facility. When the ECU has received the charging start signal, it does not perform re-diagnosis processing.

The present invention makes it possible to integrate and control in one circuit the systems, such as electric power components, a driving motor, a stack, and an AC condenser which have the maximum enthalpy under similar operational temperature and use conditions, by using an integrated radiator. Therefore, it is possible to minimize air-through resistance of the radiator for cooling the stack and the electric power components and ensure smooth and stable cooling performance of the stack, electric power components, and AC condenser while improving fuel efficiency by reducing the condensation pressure of the air conditioner. Further, it is possible to improve cooling efficiency by non-repeatedly arranging heat exchangers, and reduce the weight of a vehicle, volume of the parts, and the manufacturing cost, by avoiding using too many parts, such as a radiator, a water pump, and a reservoir tank.
