Abstract:
1. A motor-driven power steering system, comprising: a steering column connected to a steering wheel; a motor with a rotation shaft connected to the steering column; a decelerator that rotates by interacting with the rotation shaft; a left fixing part mounted at a left wheel; a right fixing part mounted at a right wheel; a left link member rotatably connecting the decelerator to the left fixing part; a right link member rotatably connecting the decelerator to the right fixing part; a detecting part for detecting a vehicle state; and motor driving means for generating steering assist force by operating the motor, which is supplied with a current determined on the basis of the vehicle state detected from the detecting part; wherein one fixing part is disposed at a front of one wheel and the other fixing part is disposed at a rear of the other wheel in relation to rotation center points of the wheels, respectively, and connecting points of the decelerator and link member are symmetrically positioned on the diameter of the decelerator.
