Patent number: 10807597Abstract: A control device that includes an electronic control unit that is configured to perform lock-up engagement pressure control for acceleration upon acceleration of a vehicle where vehicle speed is increased by increasing a rotational speed of the internal combustion engine, the lock-up engagement pressure control for acceleration controlling engagement pressure of the lock-up clutch, wherein in the lock-up engagement pressure control for acceleration, when an actual rotational speed of the input has reached greater than or equal to a reference rotational speed, the electronic control unit is configured to start engagement pressure increase control, the reference rotational speed being lower than a target rotational speed of the internal combustion engine, and the engagement pressure increase control increasing the engagement pressure of the lock-up clutch.Type: GrantFiled: November 14, 2017Date of Patent: October 20, 2020Assignees: AISIN AW CO., LTD., TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Eiji Moriyama, Kiyoshi Kurita, Kazuharu Asai, Munenori Terada, Makoto Sawada, Shinya Toyoda

Patent number: 10759435Abstract: A control device that controls a vehicle transmission device including an input drivingly coupled to an internal combustion engine, an output drivingly coupled to wheels, a shift input drivingly coupled to the input via a fluid coupling having a lock-up clutch, and a speed change mechanism disposed on a power transmission path connecting the shift input and the output, wherein the speed change mechanism is capable of performing both continuously variable shifting that continuously changes a speed ratio, and stepped shifting that changes a speed ratio in a stepwise manner, the control device including: an electronic control unit that is configured to perform, when the stepped shifting is performed, rotation maintained engagement control that controls an engagement pressure of the lock-up clutch such that a rotational speed of the input follows a predetermined target rotational speed, regardless of a change in rotational speed of the shift input.Type: GrantFiled: February 24, 2017Date of Patent: September 1, 2020Assignees: AISIN AW CO., LTD., TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Munenori Terada, Takemichi Isono, Makoto Sawada, Naoto Tanaka

Patent number: 10682910Abstract: A control apparatus for a vehicle including an engine, drive wheels, a drive-force transmitting apparatus, a hydraulic pressure sensor and a pump. The control apparatus makes a determination as to whether a failure occurs in the hydraulic pressure sensor, based on a detected value of a pulley hydraulic pressure by which a primary pulley or a secondary pulley of a continuously-variable transmission mechanism of the drive-force transmitting apparatus is to be operated. The control apparatus makes the determination until a given length of time elapses from a point of time at which the hydraulic pressure sensor becomes ready to detect the pulley hydraulic pressure after initiation of supply of an electric power to at least the hydraulic pressure sensor in an operation stopped state of the engine. The control apparatus does not make the determination after the given length of time elapses from the above-described point of time.Type: GrantFiled: March 5, 2019Date of Patent: June 16, 2020Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Taichi Washio, Munenori Terada
