摘要： The present invention provides an electric power steering apparatus for controlling a motor based on a current command value calculated from a steering assist command value calculated based on a steering torque generated in a steering shaft and from a current detection value of the motor which gives a steering mechanism a steering assist force. In order to realize ideal road information sensitivity and steering feeling in frequency region at the same time, the electric power steering apparatus comprises a torque filter for processing a torque signal, an SAT estimating function, and an SAT filter for signal-processing SAT information from the SAT estimating function, and the electric power steering apparatus also comprises a control system with two degree of freedom which is capable of independently designing frequency characteristics of steering feeling and road information sensitivity.

摘要： An electrically driven power steering apparatus is structured such that a large impact on a rack shaft occurs upon an impingement of a steering stopper, and, even when an axial force acting on a ball bearing of a presser member becomes zero, a rotation of the presser member is hindered by caulking c at a thin plate member. Therefore, the presser member does not slacken, and a predetermined axial force can be given again to the ball bearing when the impact dissipates. The thus structured power steering apparatus exhibiting, though the cost is low, an excellent shockproof characteristic and capable of preventing the bearing from coming off a ball screw nut, can be provided.
