Patent number: 10513257Abstract: An ignition switch is turned on, 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. 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. Then, when the abnormality is eliminated, the real failure is not established, and the fail-safe process of an engine is finished. Then, when the ignition switch is turned off 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.Type: GrantFiled: December 9, 2013Date of Patent: December 24, 2019Assignee: MITSUBISHI JIDOSHA KOGYO KABUSHIKI KAISHAInventors: Yoshihiro Omi, Katsunori Ueda, Kazunori Handa, Masayuki Takagaki, Dairoku Ishii
