A motor-driven power steering apparatus is provided with a self-aligning
torque computing means for computing a self-aligning torque based on of a
steering angle and a vehicle speed, a friction torque computing means for
computing a friction torque in accordance with a steering angle change
from a steering angular velocity, an apparent steering torque computing
means for computing an apparent steering torque from the friction torque
and a steering torque, and a steering torque feedback control means for
driving and controlling an assist motor in such a manner that a
difference between the self-aligning torque and the apparent steering
torque becomes 0.
