If an abnormality occurs in a vehicle, an abnormality detected-time control is performed in accordance with the kind of the abnormality. An output characteristic of the vehicle is selected in accordance with the kind of the abnormality, so that safety at the time of occurrence of an abnormality can be improved. When such output restriction is performed, the restriction is tightened stepwise. Therefore, safety at the time of occurrence of an abnormality is further improved.
