An electric vehicle includes engine (20) in which the amount of fuel supply is controlled by a throttle valve (23a), an electricity generator (32) that produces electricity using the power of the engine (20), an electric motor (34) outputs power to the drive shaft (35), an EGR system (27) that supplies exhaust gas, exhausted from the engine (20), to a manifold (23) of the engine (20), a clutch (31b) that switches between the transmission and the non-transmission of power from the engine (20) to the drive shaft (35), a pressure sensor (28) that measures the change of an internal pressure of the manifold (23) before and after the EGR system (27) supplies the exhaust gas to the manifold (23), and ECU (100) that performs fault detection of the EGR system (27) using the pressure sensor (28) when conditions, where a series mode is selected, the degree of opening of the throttle valve (23a) is constant, are satisfied. |
