In a hybrid vehicle (100), first, an engine (5) is locked by an engine shaft locking mechanism (13). A first motor (MG1) is operated by torque control and a second motor (MG2) is operated by number-of-revolutions control. Torque for controlling the second motor (MG2) in this state is obtained. Based on the obtained control torque, whether the first motor (MG1) is normal is checked. Successively, the second motor (MG2) is operated by the torque control and the first motor (MG1) is operated by the number-of-revolutions control to check whether the second motor (MG2) is normal in a similar manner. |
