Patent number: 11840295Abstract: A steering system includes a steering shaft; a motor configured to generate a torque applied to the steering shaft; and a control unit configured to control the motor. The control unit has a function of performing steering angle feedback control for causing a steering angle that is a rotation angle of a steering wheel to reach a target steering angle that is set based on a point of view of adjusting a rotational position of the steering wheel, as an adjustment process of adjusting the rotational position of the steering wheel. The control unit is configured to set a limit value for limiting a change range of the target steering angle with respect to the steering angle at each moment in a period in which automatic rotation of the steering wheel is hindered in a case where the automatic rotation is hindered while the adjustment process is being performed.Type: GrantFiled: June 14, 2021Date of Patent: December 12, 2023Assignees: JTEKT CORPORATION, TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yusuke Kakimoto, Yoshiyuki Uchino, Kenji Shibata, Takafumi Sato

Patent number: 11834115Abstract: A steering system includes a steering shaft; a reaction motor; and a control unit configured to control the reaction motor. The control unit has a function of performing a correction process of rotating the steering wheel using the reaction motor such that a displacement in a rotational position of the steering wheel with respect to a correct rotational position corresponding to a turning position of the turning wheels decreases when a power supply of the vehicle is turned on and the rotational position of the steering wheel is different from the correct rotational position. The control unit is configured to perform the correction process when the displacement is equal to or greater than a predetermined permissible value and not to perform the correction process when the displacement is less than the permissible value.Type: GrantFiled: June 14, 2021Date of Patent: December 5, 2023Assignees: JTEKT CORPORATION, TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yusuke Kakimoto, Yoshiyuki Uchino, Kenji Shibata, Takafumi Sato

Patent number: 11814121Abstract: A steering device includes a steering shaft, a motor, a stopper mechanism, and a controller. The controller is configured to execute a first process and a second process when a determined condition is established. The first process includes causing the steering wheel to operate to a first operation end through control of the motor and thereafter operate in reverse to a second operation end. The second process includes computing a neutral position of the steering wheel based on a rotational angle of the motor at a time when reverse operation of the steering wheel is started and at a time when the reverse operation of the steering wheel is ended.Type: GrantFiled: June 7, 2021Date of Patent: November 14, 2023Assignee: JTEKT CORPORATIONInventors: Yusuke Kakimoto, Yoshiyuki Uchino, Kenji Shibata, Takafumi Sato

Publication number: 20230011119Abstract: A steering control device controls, as a target, a steering device including a steering actuator and a turning actuator that has a structure with a power transmission path cut off from the steering actuator, and can reflect a state of an automated driving command. A control unit is configured to execute: turning-side synchronization control when the absolute value of a deviation amount is a value within a first range; steering-side synchronization control when the absolute value of the deviation mount is a value within a second range that is a larger value than a value within the first range; and at least one of the turning-side synchronization control and the steering-side synchronization control when the absolute value of the deviation amount is a value within a third range that is a value between a value within the first range and a value within the second range.Type: ApplicationFiled: June 1, 2022Publication date: January 12, 2023Applicant: JTEKT CORPORATIONInventors: Yoshiyuki UCHINO, Isao NAMIKAWA, Takashi KODERA, Kenji SHIBATA, Takafumi SATO
