The motor-driven power steering may include a user selection unit, a driving motor unit, and a control unit that includes a basic current map creating driving torque according to a vehicle speed for controlling the driving motor unit by using a vehicle speed and steering torque input through CAN communication and a sub-current map obtained by reducing the basic current map at a predetermined reduction ratio, creates adjustment torque corresponding to an adjustment signal adjusted by the user selection unit by using the sub-current map, and includes a sub-functional logic adjusting driving torque created by the basic current map by the created adjustment torque, a driving torque compensation map compensating adjustment driving torque adjusted by the sub-functional logic in accordance with the traveling state of a vehicle, and a driving logic that controls the driving motor unit by using compensation driving torque compensated by the driving torque compensation map. |
