Abstract

In a control device of an electric power steering device, a q-axis current command value calculation unit which calculates a current command value for a motor for producing assist torque is provided with a q-axis current limitation value calculation unit which calculates a q-axis current limitation value such that, in a case where the absolute value of a steering angle is equal to or greater than a predetermined first steering angle threshold, the q-axis current limitation value decreases with increase in the absolute value of the steering angle, thereby restricting a q-axis current command value. Thus, a steering operation is prevented from being performed to a maximum steering angle θmax and impact by end contact can be mitigated.
