摘要： 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.
