摘要： An electric power steering system is provided which is capable of providing a favorable steering feeling without using compensation logics such as of inertia compensation and friction compensation. The electric power steering system includes road-noise suppression control means (213) for controlling a steering assist motor (9) in a manner to damp torque transmission in a higher frequency region representing road noises than a frequency region representing road information. A friction value of a steering mechanism (A) is decreased enough to allow the intrinsic vibrations of the steering mechanism (A) to appear. Rotor inertia of the steering assist motor (9) is set to a value small enough to allow the frequencies of the intrinsic vibrations to be present in the frequency region where the torque transmission is damped by the road-noise suppression control means (213).

摘要： With the steering apparatus, a tilt can be adjusted by sliding a column bracket, which is fastened to a column housing supporting a steering shaft so as to be rotatable, along tilting apertures provided at side walls of a tilting bracket. A contact projection which is projected toward a stopper from a substantially center portion of the column bracket for limiting a tilt angle crashes into the stopper with a slide of the column bracket caused by a secondary crash and pushes the stopper into guiding apertures arranged in an extension to the tilting apertures. The steering apparatus can realize absorption of energy of a secondary crash by increasing a tilt angle always under a proper condition, while high accuracy is unnecessary in shaping related parts.
