Patent number: 11597377Abstract: A vehicle control apparatus includes an overlapping-prediction determination portion configured to determine whether or not it is predicted that, during execution of a synchronous control for placing a clutch, which is provided between an engine and an electric motor, into an engaged state, a synchronization-completion time point of the clutch overlaps with an inertia phase period in process of a shift control of a transmission, and a torque limitation portion configured, when the overlapping-prediction determination portion determines that it is predicted that the synchronization-completion time point overlaps with the inertia phase period, to execute a torque limitation by which at least one of a torque capacity of the clutch and an output torque of the engine is made smaller than when the overlapping-prediction determination portion determines that it is not predicted that the synchronization-completion time point overlaps with the inertia phase period.Type: GrantFiled: June 16, 2022Date of Patent: March 7, 2023Assignees: TOYOTA JIDOSHA KABUSHIKI KAISHA, AISIN CORPORATIONInventors: Keigo Matsubara, Masayuki Baba, Tomoya Inayoshi, Takuma Sugino

Patent number: 11052904Abstract: When starting a skip downshift, a controller for an automatic transmission disengages two or more engagement elements that are in an engaged state. The disengaging two or more engagement elements includes setting a first engagement element, which is one of the two or more engagement elements that are disengaged and is used to form an intermediate gear stage having a lower transmission ratio than a post-shifting gear stage, to an engagement preparation state that maintains a state immediately before the engaged state. Subsequently, the controller engages a second engagement element, which is used to form both the intermediate gear stage and the post-shifting gear stage, and temporarily increases engagement pressure of the first engagement element. The controller disengages the first engagement element and engages a third engagement element, which is used to form the post-shifting gear stage, to form the post-shifting gear stage.Type: GrantFiled: February 13, 2020Date of Patent: July 6, 2021Assignees: TOYOTA JIDOSHA KABUSHIKI KAISHA, AISIN AW CO., LTD.Inventors: Tomohiro Chimbe, Keisuke Ota, Yuji Kajiyama, Daiki Fukuda, Kazuki Imanishi, Takuma Sugino

Patent number: 10808835Abstract: A shift control device of a vehicle including an internal combustion engine and a multi-speed transmission in series, the shift control device comprises: a control portion providing a downshift control in which an input shaft rotation speed of the multi-speed transmission is increased through a torque-up of the internal combustion engine toward a post-shift input shaft rotation speed in a neutral state where a release-side engagement device to be released during a downshift of the multi-speed transmission is released, so as to engage an engagement-side engagement device to be engaged after the shift. In the case of a shift pattern having a large internal inertia of the multi-speed transmission, the control portion controls a torque capacity of the engagement-side engagement device to a value greater than zero before starting a torque-up control of the internal combustion engine.Type: GrantFiled: March 1, 2018Date of Patent: October 20, 2020Assignees: TOYOTA JIDOSHA KABUSHIKI KAISHA, AISIN AW CO., LTD.Inventors: Norihiro Tsukamoto, Tomohiro Asami, Hiromasa Takai, Masataka Hirano, Daiki Fukuda, Takuma Sugino
