摘要： The present disclosure relates to a technology of estimating rack force using force that is transmitted from a steering motor of a Steer-By-Wire (SBW) system to a rack bar. The present disclosure provides a method for estimating rack force of an SBW system, the method calculating restoring force that is applied to a reducer on the basis of the difference between position values of the rack bar that are obtained at the front end and the rear end of the reducer when the position of the rack bar is changed by operation of a steering motor; and calculating rack force by reflecting the restoring force to a motion equation including inertia force of the SBW system.
