Patent number: 11685428Abstract: A steering control device includes a control circuit and a drive circuit. The control circuit is configured to perform a current feedback computation by which the actual current value of electric current to be supplied to a motor follows a current command value. The control circuit is configured to execute an end-abutting relaxation control to correct the current command value such that decrease in an end interval angle is restricted, when the end interval angle is equal to or smaller than a predetermined angle, the end interval angle indicating the distance of the absolute steer angle from the end position correspondence angle. The control circuit is configured to adjust a control gain to be used in the current feedback computation, such that the control gain increases, when overshoot of the actual current value occurs during the execution of the end-abutting relaxation control.Type: GrantFiled: August 31, 2020Date of Patent: June 27, 2023Assignee: JTEKT CORPORATIONInventors: Nobuaki Kataoka, Takahiro Toko, Takafumi Yamaguchi, Yukinobu Ezaki
