According to the present invention, disclosed is an electric power steering apparatus having a redundancy structure. According to the present invention, an electric power steering apparatus having a redundancy structure comprises: a driving motor driving a steering wheel; first and second power circuits supplying control power; first and second driving circuits driving the driving motor; first and second position sensors sensing a rotation position of the driving motor; and first and second processors operatively coupled to the driving motor, the first and second power circuits, the first and second position sensors, and the first and second driving circuits, respectively. The first processor receives a steering control signal from an upper control device and operates the driving motor by operating the first driving circuit based on the first position sensor. The second processor receives the steering control signal from the upper control device and operates the driving motor by operating the second driving circuit based on the second position sensor.

    본 발명은 리던던시 구조의 전동식 조향장치가 개시된다. 본 발명의 리던던시 구조의 전동식 조향장치는, 조향휠을 구동시키는 구동모터; 제어전원을 공급하는 제1 내지 제2 전원회로; 구동모터를 구동시키는 제1 내지 제2 구동회로; 구동모터의 회전위치를 감지하는 제1 내지 제2 위치센서; 및 구동모터, 제1 내지 제2 전원회로, 제1 내지 제2 위치센서 및 제1 내지 제2 구동회로와 각각 작동적으로 연결(operatively coupled to)된 제1 내지 제2 프로세서;를 포함하되, 제1 프로세서는, 상위 제어장치로부터 조향 제어신호를 입력받아 제1 위치센서에 기초하여 제1 구동회로를 작동시켜 구동모터를 작동시키고, 제2 프로세서는, 상위 제어장치로부터 조향 제어신호를 입력받아 제2 위치센서에 기초하여 제2 구동회로를 작동시켜 구동모터를 작동시키는 것을 특징으로 한다.
