Patent number: 10724456Abstract: A vehicle includes an internal combustion engine including an exhaust passage, a catalyst provided in the exhaust passage, and an electronic control unit. When the engine stop condition is established, the electronic control unit stops fuel injection and increases a catalyst inflow oxygen amount that is an amount of oxygen flowing into the catalyst by a specified oxygen increase amount. The engine stop condition is a condition for stopping operation of the internal combustion engine. The specified oxygen increase amount is larger than an increased part of the catalyst inflow oxygen amount that is increased by the stop of the fuel injection.Type: GrantFiled: May 21, 2018Date of Patent: July 28, 2020Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Koji Miwa, Koichi Kitaura, Takahiro Tsukagoshi, Kenji Inoshita, Kazuya Suzuki, Takeru Yoshida, Isao Chinzei, Kaoru Otsuka

Patent number: 10502154Abstract: An electronic control unit of a control device for an internal combustion engine executes, for a first cycle, first drive processing for controlling an actuator such that a pin drive operation is executed for switching from a first cam to a second cam, executes second drive processing for controlling the actuator such that the pin drive operation is executed again for a second cycle, and executes abnormality determination processing for determining that a cam switching mechanism has an abnormality in a case where a pin returns to a reference position by using a pin return section following a cam switching section of the first cycle after the execution of the first drive processing and the pin returns to the reference position by using the pin return section following the cam switching section of the second cycle after the execution of the second drive processing.Type: GrantFiled: July 3, 2018Date of Patent: December 10, 2019Assignee: Toyota Jidosha Kabushiki KaishaInventors: Keisuke Sasaki, Noriyasu Adachi, Shigehiro Sugihira, Takayoshi Kawai, Shinji Sadakane, Kaoru Otsuka

Patent number: 10465573Abstract: In a system that selects a large-cam as a driving cam at a time of a start of an engine, when an engine stop request is output, it is determined whether there is a small-cam cylinder for which a small-cam is selected as the driving cam. In a case where it is determined that there is a small-cam cylinder, a switching command for switching the driving cam from the small-cam to the large-cam is output. When an engine start request is output, the above determination is performed again. In a case where it is determined that there is a small-cam cylinder, the switching command is output to all solenoid actuators again. In addition, the drive of the fuel injector is suspended until the switching operation of the driving cam is completed for all cylinders.Type: GrantFiled: February 5, 2018Date of Patent: November 5, 2019Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Shigehiro Sugihira, Noriyasu Adachi, Keisuke Sasaki, Takayoshi Kawai, Kaoru Otsuka, Shinji Sadakane, Hiroyuki Sugihara

Patent number: 10329962Abstract: At crank angle CA10 at which the switch request of the drive cam was issued, the ejection operations of the pins at all the solenoid actuators started simultaneously. The ejected pins are seated on the cam carriers at crank angle CA12. The pin seated on the cam carrier moves along the grooves in accordance with the rotation of the cam carrier. The earliest finish timing of the switch operation of the drive cam is at crank angle CA13 (#4 cylinder). At the crank angle CA13, drive of the fuel injector and the ignition device in each cylinder is permitted.Type: GrantFiled: January 23, 2018Date of Patent: June 25, 2019Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Takayoshi Kawai, Noriyasu Adachi, Shigehiro Sugihira, Keisuke Sasaki, Kaoru Otsuka, Shinji Sadakane, Hiroyuki Sugihara

Patent number: 10030596Abstract: In starting the engine, if it is determined that large cams are not completely prepared for all driving cams, valve closing timings of all intake valves are changed by driving the VVT so that all of the cylinders have equal in-cylinder filling efficiency. A fuel injection amount of each cylinder is determined by a feedforward control assuming that the large cams are completely prepared for all of the driving cams. When the valve closing timing of all of the intake valves are changed by driving the VVT to equalize the in-cylinder filling efficiencies of all of the cylinders, all of the cylinders have substantially equal in-cylinder air-fuel ratios.Type: GrantFiled: October 16, 2017Date of Patent: July 24, 2018Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Hiroyuki Sugihara, Kaoru Otsuka, Shinji Sadakane, Noriyasu Adachi, Shigehiro Sugihira, Keisuke Sasaki, Takayoshi Kawai

Patent number: 8515652Abstract: A control device for an internal combustion engine is provided. The control device includes means which controls fuel injection by a fuel injection device, and means which controls the throttle. The fuel injection control means sequentially restarts fuel injection for each cylinder in accordance with an ignition sequence among cylinders when cancellation conditions of fuel cut are satisfied during implementation of the fuel cut. Meanwhile, the throttle control means firstly controls the throttle to a closing side when the cancellation conditions of fuel cut are satisfied. The throttle is controlled to the closing side, whereby the air amount in the intake pipe is decreased, and the air amount in a cylinder which is the basis of calculation of a fuel injection amount is also decreased.Type: GrantFiled: March 24, 2009Date of Patent: August 20, 2013Assignee: Toyota Jidosha Kabushiki KaishaInventors: Shinichi Soejima, Naoto Kato, Kaoru Otsuka, Kiyonori Takahashi, Hiroyuki Tanaka, Ryutaro Moriguchi

Patent number: 8110662Abstract: A cDNA fragment participating in the maintenance of smooth muscle differentiation was isolated using a culture system of chicken gizzard smooth muscle cells, the differential display method and the subtracted hybridization method. Using the obtained cDNA sequence as a query, cDNA sequences of Helix Research Institute (Japanese Patent Application No. 2000-118776) were retrieved, and thus, a novel gene “C-NT2RP3001495” was obtained. The protein encoded by this gene has two WW domains that participate in protein interactions in the N-terminal domain. Evidence suggests that this protein binds to other proteins, and thus regulates the intracellular signal transduction, gene expression, and so on, thereby participating in the maintenance of the differentiation of smooth muscle cells. This protein and compounds regulating the expression thereof are markedly useful in developing drugs for various diseases associated with abnormality in the maintenance of smooth muscle cell differentiation.Type: GrantFiled: October 9, 2007Date of Patent: February 7, 2012Assignees: Chugai Seiyaku Kabushiki KaishaInventors: Toshio Ota, Takao Isogai, Tetsuo Nishikawa, Koji Hayashi, Kaoru Otsuka, Jun-Ichi Yamamoto, Shizuko Ishii, Tomoyasu Sugiyama, Ai Wakamatsu, Keiichi Nagai, Tetsuji Otsuki, Shin-Ichi Funahashi, Shoji Miyata, Kenji Sobue, Kenichiro Hayashi
