Patent number: 12240493Abstract: 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: GrantFiled: January 26, 2023Date of Patent: March 4, 2025Assignees: ADVICS CO., LTD., J-QUAD DYNAMICS INC., DENSO CORPORATION, AISIN CORPORATION, JTEK CorporationInventor: Yosuke Ohmori

Publication number: 20250002079Abstract: A vehicle includes vehicle devices configured to adjust a lateral movement amount of the vehicle, and a steering wheel lock mechanism. The vehicle devices include a front-wheel steering device and a remaining device that is a device other than the front-wheel steering device. When there is an anomaly in the front-wheel steering device, a vehicle control device switches a state of the steering wheel lock mechanism from a deactivated state to an activated state. The control device adjusts the amount of lateral movement of the vehicle by activating the remaining device when rotation of the steering wheel is disabled.Type: ApplicationFiled: September 22, 2022Publication date: January 2, 2025Applicants: ADVICS CO., LTD., J-QuAD DYNAMICS INC., DENSO CORPORATION, AISIN CORPORATION, JTEKT CORPORATIONInventor: Yosuke OHMORI

Publication number: 20230304804Abstract: A controller computes availability of the vehicle that indicates a range reachable by the vehicle by actuation of the actuator and generates a first travel route within a range of the availability of the vehicle, as a travel route followed by the vehicle, when the vehicle travels along a road ahead of the vehicle from a present position. When the road includes a curve and the first travel route cannot be generated within the availability range, the controller sets a target position to a position in the road located before the curve and generates a second travel route within the availability range, as the travel route followed by the vehicle, to stop the vehicle at the target position.Type: ApplicationFiled: January 26, 2023Publication date: September 28, 2023Applicants: ADVICS CO., LTD., J-QuAD DYNAMICS INC., DENSO CORPORATION, AISIN CORPORATION, JTEKT CORPORATIONInventor: Yosuke OHMORI

Patent number: 10384629Abstract: A collision avoidance device includes a collision avoidance executor, a determiner, and a collision avoidance controller, for example. The collision avoidance executor can execute a collision avoidance function for a vehicle to avoid collision with an object to be avoided. The determiner determines, based on an operation of an accelerator pedal by a driver, whether the driver has an intention of acceleration. The collision avoidance controller inhibits execution of the collision avoidance function when the driver is determined to have the intention of acceleration. The determiner further determines, based on the operation of the accelerator pedal, whether the driver has an intention of cancelation of the collision avoidance function. The collision avoidance controller ends the execution of the collision avoidance function when the driver is determined to have the intention of cancelation during the execution of the collision avoidance function.Type: GrantFiled: November 27, 2015Date of Patent: August 20, 2019Assignees: ADVICS CO., LTD., TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yosuke Ohmori, Wataru Ike
