Abstract

See full text

An apparatus for compensating for a stick-slip of a Motor Driven Power Steering (MDPS) system may include: a column torque detection unit to detect column torque applied to a steering shaft as a driver operates a steering wheel; a vehicle speed sensor to detect vehicle speed; a steering angular velocity detection unit to detect a steering angular velocity of a steering wheel; a condition determination unit to determine whether at least one of the column torque, the vehicle speed and the steering angular velocity satisfies a preset compensation condition; a stick-slip compensation controller to output a compensation current for compensating the stick-slip using at least one of the steering angular velocity, the column torque and the vehicle speed; and a compensation unit to compensate for an output of an MDPS controller by applying the compensation current to the output of the MDPS controller.
