A steering controller for controlling an electric power steering includes a load estimator estimating a road surface load, a pre-correction target determiner determining a pre-correction target steer torque based on the estimated road surface load, a steer angle detector detecting a steer angle, and a target corrector correcting the pre-correction target steer torque based on the steer angle, and the controller determines an assist torque instruction value based on the deviation between the target steer torque and a steer torque, thereby establishing a robust steering feel of an electric power steering system irrespective of the change of the mechanical friction of the power steering system.
