Patent number: 11919581Abstract: A steering control device includes an electronic control unit. The electronic control unit is configured to perform end contact relaxation control for correcting a current command value such that a decrease of an end separation angle indicating a distance of an absolute steering angle from an end-position-corresponding angle is limited when the end separation angle is equal to or less than a predetermined angle and to perform partial release control for decreasing a correction value of the current command value due to execution of the end contact relaxation control based on a steering torque which is input to a steering system when a vehicle is intended to travel while turning at the time of execution of the end contact relaxation control.Type: GrantFiled: October 14, 2020Date of Patent: March 5, 2024Assignee: JTEKT CORPORATIONInventors: Takafumi Yamaguchi, Takahiro Toko, Nobuaki Kataoka, Shingo Nitta, Yukinobu Ezaki
