Patent number: 11987177Abstract: A travel controller recognizes an action of a driver of a vehicle from image data of the driver. The travel controller obtains information indicating that determination of whether autonomous driving of the vehicle is permissible cannot be given. When the information indicating that determination of whether the autonomous driving of the vehicle is permissible cannot be given is obtained, the travel controller operates a human interface to request the driver for an instruction to drive the vehicle. The travel controller determines whether the driver is giving an instruction to drive the vehicle from an action of the driver recognized in response to the request for an instruction to drive the vehicle. When determined in the determination process that the driver is giving an instruction to drive the vehicle, the travel controller operates a drive system of the vehicle to permit autonomous driving of the vehicle.Type: GrantFiled: October 27, 2021Date of Patent: May 21, 2024Assignee: J-QuAD DYNAMICS INC.Inventors: Akira Ito, Daisuke Tokumochi

Publication number: 20230242146Abstract: A vehicle includes a sideslip preventing function of preventing a sideslip of the vehicle by separately adjusting a longitudinal force applied to each of the wheels. A controller controls the vehicle based on requests input from a driver assistance device, thereby causing the vehicle to travel autonomously. The controller calculates wheel lateral force request values based on the requests input from the driver assistance device. The wheel lateral force request values are request values of lateral forces acting on the respective wheels. The controller, when a behavior of the vehicle is in an oversteer state in a case in which the sideslip preventing function is failing, limits the wheel lateral force request values for the front wheels to values less than or equal to a first lateral force limit value, which is a limit value of the lateral force that can act on the rear wheels.Type: ApplicationFiled: January 26, 2023Publication date: August 3, 2023Applicants: ADVICS CO., LTD., J-QUAD DYNAMICS INC., DENSO CORPORATION, AISIN CORPORATION, JTEKT CorporationInventor: Yosuke OHMORI
