Abstract:

According to the present invention, unlike to motor-driven power steering systems in the related art, it is possible to generate an appropriate assistant steering force that is required to drive the motor according to steering of the driver, without expensive components, such as a torque sensor and an electronic controller, such that it is possible to achieve a motor-driven power steering system having a simple structure at a low cost.

Abstract(Chinese):

根据本发明，与现有技术中的电动动力转向系统不同，可以产生根据驾驶员的转向而驱动马达所需的适当辅助转向力，而不需要昂贵的部件，例如扭矩传感器和电子控制器，使得可以以低成本实现具有简单结构的电动机动力转向系统。
