Abstract: An apparatus of limiting a steering angle in a steer-by-wire (SBW) system, may include a steering column rotating in association with a steering wheel; a striker which is provided to penetrate the steering column and rotates together with the steering column, and has a guide pin and a stopper pin; and a disk member that has a spiral sliding slot formed on a surface facing the guide pin, and a stopper formed on a position limiting a maximum steering angle of the steering column in a process of the guide pin rotating along the sliding slot and the striker being translated with respect to the steering column, so that the stopper pin is caught by the stopper in the rotation and translation motions of the striker.

Abstract: Disclosed is a method of controlling a motor driven power steering system (MDPS). The method includes multiple operations including a torque sensor failure determining operation of determining failure of the torque sensor according to existence of a torque sensor signal input from the torque sensor; a control module calculating operation of, when it is determined that the torque sensor has failure, receiving control signals from a steering angle sensor and a motor angle sensor and calculating a plurality of control modules including a basic assist generating module, an assist maintaining module, and an overshoot preventing module; and an MDPS motor driving operation of driving a motor of the MDPS based on motor torque calculated through the control module.
