摘要： A method of adjusting friction of an MDPS unit may include detecting road surface conditions of a road on which a vehicle travels; classifying the road on which the vehicle travels into a normal road, a low frictional road, a road having a first uneven road surface, and a road having a second uneven road surface; and reducing friction of the MDPS unit of the vehicle when the road on which the vehicle travels is determined as the road having the first uneven road surface.

摘要： Disclosed is a method of control a motor driven power steering system. The method includes determining an end holding driving, by a control unit, turning on/off a damping boost gain application mode according to a result of determination for the end holding driving, by the control unit, multiplying an output value according to turning on/off of the damping boost gain application mode by an output value from the damping output value detection unit, and outputting the multiplied value as a damping correction value, by the control unit, and reflecting the damping correction value to control an output torque of a motor in a rack-end-stop control period, by the control unit.

摘要： A method for controlling a motor driven power steering (MDPS) system includes detecting, by a controller, a current position of a rack bar; comparing, by the controller, the current position of the rack bar with a preset maximum position of the rack bar; updating, by the controller, the maximum position of the rack bar according to the comparison result; and setting, by the controller, a rack end stop control section using the updated maximum position of the rack bar.

摘要： A method for controlling a motor driven steering system includes setting a reference point of a motor angle by a control unit, estimating a steering angular speed and a steering angle using the reference point by the control unit, determining whether the steering angle is included within a predetermined setting range by the control unit, and controlling an output torque of the motor driven steering system by the control unit using the steering angular speed and the steering angle, when the steering angle is included within the setting range.
