Abstract
A steering control device includes an electronic control unit. The electronic control unit is configured to detect an absolute steering angle, to calculate a current command value, to control driving of a motor such that an actual current value which is supplied to the motor reaches the current command value, to store an end-position-corresponding angle which is correlated with the absolute steering angle, to perform end contact relaxation control for correcting the current command value such that a decrease of an end separation angle is regulated when the end separation angle is equal to or less than a predetermined angle, and to calculate the current command value such that an increase of the end separation angle is not regulated by the end contact relaxation control when the end separation angle is equal to or less than the predetermined angle.
