摘要： 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 (50) so as to control a current flowing through the motor (50) 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 (34) 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 (50) when the end determination processing portion determines that the turning angle has reached the limit angle.

摘要： A steering control device includes a feedback processing portion configured to control a current flowing through a motor (50) to a current command value; an end determination processing portion configured to determine whether a turning angle of steered wheels (34) 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 (50) 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 (50).
