  • Publication number: 20180057043
    Abstract: A steering control device includes a feedback processing portion configured to control a current flowing through a motor to a 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 limit a magnitude of the current command value to a magnitude of a limited current value or smaller, when the end determination processing portion determines that the turning angle has reached the limit angle. The limited current value is a value obtained by performing correction to decrease a magnitude of a detected value of the current flowing through the motor at a time when the end determination processing portion determines that the turning angle has reached the limit angle, based on a degree of a decrease in a magnitude of a rotational speed of the motor.
