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.
