ABSTRACT:
This invention is an electric power steering apparatus for applying the power of an electric motor to a steering system to reduce the steering torque, comprising a steering torque detection means, steering rotating speed detection means, a differential operation means, an electric motor control signal determination means, and an electric motor drive means. The apparatus detects the steering torque and steering rotating speed of the steering system to generate as an electric motor control signal a control quantity obtained by damping the value corresponding to the steering rotating speed from the value corresponding to the steering torque and then adding to the result a steering torque differential value in order to drive the electric motor based on this electric motor control signal, thereby enabling a steering assist torque corresponding to a change in the steering torque to be obtained even when a steering operation with a sudden increase in the steering torque is performed and thus enabling a responsive steering assist torque to be generated to improve the steering feeling.
