APPARATUS FOR AND METHOD OF CONTROLLING STEER-BY-WIRE STEERING SYSTEM

Proposed is an apparatus for controlling a steer-by-wire steering system, the apparatus comprising: a steering angle sensor configured to detect a steering angle position; a steering position control command receiver configured to receive a steering position control command y2 from a designated external module; a processor configured to generate a steering angle position signal y1 based on the steering angle position from the steering angle sensor, compute a compensation gain x corresponding to column torque or motor electric current of a steering force actuator (SFA) when a driver's involvement occurs, compute a final steering position control command Y by reflecting the compensation gain x to the steering angle position signal y1 and the steering position control command y2, and output the final steering position control command Y to the steering force actuator (SFA).
