Publication number: 20220081023Abstract: A steering device includes a turning shaft, a turning motor, and a control device that controls the turning motor such that an angle capable of being converted into a turning angle of a turning wheel follows a target angle that is calculated depending on a steering state of a steering wheel. The control device executes a correction process of correcting the target angle. The control device corrects the target angle such that the degree of an increase in the target angle is slower as the target angle approaches a limit value of an angle region, when the target angle increases toward the limit value of the angle region in either of a vehicle stop state or an extremely low speed state.Type: ApplicationFiled: September 8, 2021Publication date: March 17, 2022Applicants: JTEKT CORPORATION, TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Junya MIYAKE, Takashi KODERA, Toru TAKASHIMA, Hidetsugu TOYAMA

Patent number: 11254348Abstract: A steer-by-wire system includes a steering reaction torque generation device mechanically separated from a turning device for turning wheels and configured to apply a reaction torque to a steering wheel. The steering reaction torque generation device has a duplex configuration including a first system and a second system, each system including a reaction torque motor. When both systems are normal, a control device generates the reaction torque having a normal characteristic by controlling an operation of the reaction torque motor of at least one system. In a case of single failure where one of the systems fails, the control device generates the reaction torque having a first characteristic by controlling an operation of the reaction torque motor of another of the systems. The reaction torque having the first characteristic is different from the reaction torque having the normal characteristic with respect to a same steering angle.Type: GrantFiled: October 31, 2018Date of Patent: February 22, 2022Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Satoru Niwa, Toru Takashima, Tetsuya Morino, Yoshio Kudo
