Publication number: 20230303162Abstract: A vehicle control device includes: a reaction device that applies a steering reaction force to a steering operation performed by a driver on a driver's vehicle; and a control device that executes steering reaction force control for controlling a value of the steering reaction force. The control device applies, to a steering operation, a reaction force having a reference value as a steering reaction force when a lane change of a driver's vehicle is not performed during execution of steering reaction force control. When the lane change of the driver's vehicle is performed, the control device sets the steering reaction force to be applied to the steering operation in a direction of the lane change of the driver's vehicle to a value smaller than the reference value.Type: ApplicationFiled: February 7, 2023Publication date: September 28, 2023Applicants: TOYOTA JIDOSHA KABUSHIKI KAISHA, DENSO CORPORATIONInventors: Yu Sakai, Takahiro Adachi, Takuma Kyo

Publication number: 20230286577Abstract: During execution of steering reaction force control, when a lane change of a host vehicle is made, a vehicle control device sets a steering reaction force given to a steering operation in the direction of the lane change of the host vehicle to a reaction force of a smaller value than a reaction force of a standard value. Further, when a vehicle approach condition that another vehicle traveling in a lane on a side to which the lane of the host vehicle is to be changed is approaching the host vehicle from behind is met at the time when a lane change of the host vehicle is made, the vehicle control device does not set the steering reaction force given to the steering operation in the direction of the lane change of the host vehicle to a reaction force of a value smaller than the standard value.Type: ApplicationFiled: December 15, 2022Publication date: September 14, 2023Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Kota KIMURA, Takahiro ADACHI, Yu SAKAI

Patent number: 10189929Abstract: An object of the present invention is to provide an active energy ray-curable composition capable of forming a cured product excellent in damage restoration, adhesion to a plastic base, and transparency after curing. An active energy ray-curable composition for optical components of the present invention essentially includes: a monomer (A) having 2 or more radical-polymerizable reactive groups (x1), a homopolymer of the monomer (A) having a glass transition temperature of higher than 200° C.; a monomer (C) having 2 or more radical-polymerizable reactive groups (x2), a homopolymer of the monomer (C) having a glass transition temperature of lower than ?15° C.; and a photopolymerization initiator (E).Type: GrantFiled: January 21, 2014Date of Patent: January 29, 2019Assignee: SANYO CHEMICAL INDUSTRIES, LTD.Inventors: Kazunori Yoshida, Yu Sakai, Keiichirou Inoue

Patent number: 9850836Abstract: An automatic control apparatus for an engine detects an operation position of a mechanical shift lever for shifting gears of a transmission, automatically stops the engine when a predetermined condition is satisfied in the case where the operation position is at a first specific range, and automatically restarts the engine in the case where, after the operation position is switched from the first specific range to a second specific range while the engine is stopped, the second specific range is maintained for a predetermined time. When the operation position is switched from the first specific range to the second specific range while the engine is stopped, it is determined whether or not the driver has an intention to start the vehicle, and if YES, the predetermined time is set to be shorter than when it is determined that there is no intention to start the vehicle.Type: GrantFiled: February 27, 2015Date of Patent: December 26, 2017Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yasutaka Oda, Hiroaki Tabuchi, Yu Sakai

Publication number: 20170191458Abstract: A vehicle control apparatus includes at least one electronic control unit (50). The electronic control unit detects a negative pressure that is generated in a negative pressure chamber (34) of a braking operation support device (32). The electronic control unit prohibits, based on the detected negative pressure of the negative pressure chamber, an internal combustion engine (26) from automatically stopping when determining that a driver does not perform the braking operation and that a speed of the internal combustion engine is at a threshold or higher continuously for a specified time period or longer. The negative pressure is generated in the negative pressure chamber in response to rotation of the internal combustion engine. The braking operation support device supports, with the negative pressure in the negative pressure chamber, the driver to perform the braking operation.Type: ApplicationFiled: June 8, 2015Publication date: July 6, 2017Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Junichi MORIMURA, Yu SAKAI, Fumichika SHIMOSE

When the operation position is switched from the first specific range to the second specific range while the engine is stopped, it is determined whether or not the driver has an intention to start the vehicle, and if YES, the predetermined time is set to be shorter than when it is determined that there is no intention to start the vehicle.Type: ApplicationFiled: February 27, 2015Publication date: March 16, 2017Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yasutaka ODA, Hiroaki TABUCHI, Yu SAKAI
