An ignition switch is turned on (a), and when an abnormality is detected in any of electronic control instruments or sensors, real failure is established, and a fail-safe process is performed (b). After a lapse of a predetermined period from the establishment of the real failure, fault determination is established, a failure level is sent, and a hybrid fail-safe process is performed (c). Then, when the abnormality is eliminated, the real failure is not established, and the fail-safe process of an engine is finished (d). Then, when the ignition switch is turned off (e) and then again turned on, sending of the failure level to a hybrid control unit is stopped, and the hybrid fail-safe process is finished (f).
