Patent number: 11964714Abstract: A steering control apparatus controls a motor used to turn a steered wheel of a vehicle, which synchronizes with a steering wheel, based on a command value. The steering control apparatus includes an electronic control unit. The electronic control unit is configured to compute a feedback control torque to be reflected in the command value. The electronic control unit is configured to compute a disturbance torque based on the feedback control torque and a predetermined angle. The electronic control unit is configured to correct the feedback control torque by using the disturbance torque. The electronic control unit is configured to correct the command value reflecting the corrected feedback control torque, based on an applied torque.Type: GrantFiled: March 3, 2021Date of Patent: April 23, 2024Assignee: JTEKT CORPORATIONInventors: Yuki Inden, Terutaka Tamaizumi

Patent number: 11702132Abstract: A steering control device includes a torque command value calculating unit configured to calculate a torque command value which is a target value of a motor torque when operation of a motor is controlled such that the motor torque is generated. The torque command value calculating unit includes a first component calculating unit configured to calculate a first component, a second component calculating unit configured to calculate a second component, and a torque component calculating unit configured to calculate a torque component. The first component calculating unit is configured to add a calculational hysteresis component to the first component such that hysteresis characteristics with respect to change of a specific state variable are provided. The torque component calculating unit is configured to perform calculation in a first calculation situation and calculation in a second calculation situation.Type: GrantFiled: March 29, 2022Date of Patent: July 18, 2023Assignees: JTEKT CORPORATION, TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yuki Inden, Isao Namikawa, Yuki Suehiro, Yoshio Kudo

Patent number: 11541931Abstract: A control apparatus for a motor includes an electronic control unit. The electronic control unit includes a first controller, a second controller, a third controller, and a fourth controller. The first controller is configured to, through execution of feedback control, compute a feedback control torque to be generated by the motor. The second controller is configured to compute a disturbance torque based on the feedback control torque and a predetermined angle. The third controller is configured to correct the feedback control torque by using the disturbance torque. The fourth controller is configured to compensate a transfer lag to the second controller between the feedback control torque and the predetermined angle.Type: GrantFiled: March 1, 2021Date of Patent: January 3, 2023Assignee: JTEKT CORPORATIONInventors: Yuki Inden, Terutaka Tamaizumi
