Abstract: 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).

Abstract: Proposed are a steer-by-wire system control apparatus and method, the apparatus including: a torque overlay control module configured to determine a target steering angle using a torque command input from a Lane Keeping Assistance System; and an actuator control module configured to control a position of a rack according to the target steering angle and thus to control a traveling direction of a vehicle.

Abstract: A torque compensation apparatus for a Motor Driven Power Steering (“MDPS”) system including: a column torque sensor configured to detect column torque applied to a steering shaft; a steering angle sensor configured to detect a steering angle of a steering wheel; and a controller configured to calculate a compensation ratio by sudden steering, based at least one of the column torque detected by the column torque sensor and a steering angular velocity calculated from the steering angle detected by the steering angle sensor. The basic assist torque outputted from the MDPS system is then compensated for according to the compensation ratio.
