Patent number: 11823047Abstract: A memory of an electronic control unit stores a neural network into which travel state quantities of a vehicle are input and from which an internal temperature of a turbocharger is output. An arithmetic processing circuit of the electronic control unit executes an internal temperature estimation process of calculating, as an estimated value of the internal temperature, an output of the neural network using measured values of the travel state quantities as an input, and a deposit amount estimation process of calculating an amount of increase in an amount of oil coke deposits based on the estimated value of the internal temperature and calculating an estimated value of the amount of oil coke deposits as a value integrating the amount of increase.Type: GrantFiled: December 13, 2021Date of Patent: November 21, 2023Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Haruto Ura

Patent number: 10570810Abstract: A vehicle forced-induction device includes a first exhaust turbine type forced-induction unit and a second exhaust turbine type forced-induction unit. The first forced-induction unit includes an outlet pipe. The outlet pipe includes a first tubular portion and an annular first flange. The second forced-induction unit includes an inlet pipe. The inlet pipe includes a second tubular portion and an annular second flange. The forced-induction device includes a fastener that includes an annular groove. The annular groove has a shape in which a width of the annular groove decreases toward a groove bottom. The fastener is wound around the first and second flanges along a circumference of the first and the second flanges, thereby housing the first and second flanges in the annular groove. The fastener fastens the first and second flanges to urge the first and second flanges toward each other.Type: GrantFiled: September 26, 2017Date of Patent: February 25, 2020Assignees: TOYOTA JIDOSHA KABUSHIKI KAISHA, AISIN TAKAOKA CO., LTD.Inventors: Takashi Tsukiyama, Haruto Ura, Tsuyoshi Uesugi, Daisuke Terui, Akihiro Hosono, Ryuta Kawazoe
