Abstract
A steering control device includes a command value setting processing portion configured to set a current command value based on a detection value of steering torque; a feedback processing portion configured to control a voltage applied to a motor so as to control a current flowing through the motor to the current command value, based on an output value of an integral element obtained by using a difference between the current and the current command value; an end determination processing portion configured to determine whether a turning angle of steered wheels has reached a limit angle; and an end-time limit processing portion configured to perform correction to increase a magnitude of the difference, based on a degree of a decrease in a magnitude of a rotational speed of the motor when the end determination processing portion determines that the turning angle has reached the limit angle.
