The present invention relates to a steering motor control device, including: a module portion configured to output power, connected to an input terminal, as a current to a steering motor connected to an output terminal based on a control signal input by a control terminal; a plurality of sensors capable of measuring the current; a first adjustment portion configured to primarily adjust a measurement area of a first sensor, which is one of a plurality of sensors, so as to be identical to a measurement area of a second sensor; a second adjustment portion configured to secondarily adjust the measurement area of the first sensor based on a first output value if a difference of the first output values output, respectively, from the first sensor for primarily adjusting the measurement area and the second sensor for fixing the measurement area is within a predetermined normal value; and a controller configured to output a control signal based on a second output value output by the first sensor for secondarily adjusting the measurement area. Accordingly, the present invention is able to improve resolution and prevent a reduction of response.
본 발명은 입력단에 연결된 전원을 제어단을 통해 입력받은 제어신호에 기초하여 출력단에 연결된 조향모터에 전류를 출력하는 모듈부와 전류를 측정할 수 있는 복수의 센서들과 복수의 센서들 중 하나인 제1 센서의 측정영역과 제2 센서의 측정영역이 동일하도록 제1 센서의 측정영역을 1차 조절하는 제1 조절부와 측정영역이 1차 조절된 제1 센서와 측정영역이 고정된 제2 센서 각각이 출력한 1차 출력값의 차이가 미리 설정된 정상값 이내이면, 1차 출력값에 기초하여 제1 센서의 측정영역을 2차 조절하는 제2 조절부 및 측정영역이 2차 조절된 제1 센서가 출력한 2차 출력값에 기초하여 제어신호를 출력하는 제어부를 포함하는 조향모터제어장치에 관한 것이다.
