Publication number: 20240068422Abstract: An upstream integrated value is an integrated value of a difference obtained by subtracting an upstream gas temperature at a starting point in time of integration from the upstream gas temperature after starting of the internal combustion engine. A downstream integrated value is an integrated value of a difference obtained by subtracting a downstream gas temperature at the starting point in time of the integration from the downstream gas temperature after the starting of the internal combustion engine. An anomaly diagnosing process obtains an anomaly determination result indicating that the exhaust purification device is in a removed state when a deviation between the upstream integrated value and the downstream integrated value is smaller than a reference level. The determination threshold is higher than a dew point.Type: ApplicationFiled: July 21, 2023Publication date: February 29, 2024Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yusuke JOH, Tomoyuki TSUJI, Yuki IKEJIRI, Masashi HAKARIYA, Makoto YAMAZAKI, Yoshikazu ASAMI, Hisao KIYONO, Tatsuaki ARISAWA, Yoshifumi MATSUDA, Tsubasa SUGANO
