The present invention relates to a motor control device. The motor control device comprises: a module unit which outputs power of a battery as a motor current applied to a steering motor based on an input control signal; an ADC output unit which outputs an ADC value including a sensing value and a first offset value of the motor current; an error determination unit which is set in advance and determines an error of a first memory in which a second offset value corresponding to the first offset value is stored; a rotation determination unit which determines whether a steering device rotates when the error of the first memory is determined; an offset input unit which inputs the ADC value as a third offset value when it is determined that the steering device does not rotate; and a control unit which outputs a control signal based on a first motor current value calculated by compensating the second offset value to the ADC value when it is determined that there is no error in the first memory and outputs a control signal based on a second motor current value calculated by compensating the third offset value to the ADC value when it is determined that there is an error in the first memory. The objective of the present invention is to provide a steering motor control technique capable of reducing steering disturbance which may be caused by a changed sensing value.

    본 발명은 입력된 제어신호에 기초하여 배터리의 전원을 조향모터에 인가되는 모터전류로 출력하는 모듈부와; 모터전류의 센싱값과 제1오프셋(Offset)값을 포함하는 ADC값을 출력하는 ADC출력부와; 미리 설정되며, 제1오프셋값에 대응되는 제2오프셋값이 저장된 제1메모리의 에러를 판단하는 에러판단부와; 제1메모리의 에러가 판단되면, 조향장치가 회전하는지를 판단하는 회전판단부와; 조향장치가 회전하지 않는 것으로 판단되면, ADC값을 제3오프셋값으로 입력하는 오프셋입력부 및; 제1메모리의 에러가 존재하지 않는 것으로 판단되면 ADC값에 제2오프셋값을 보상하여 산출된 제1모터전류값에 기초하여 제어신호를 출력하고, 제1메모리의 에러가 존재하는 것으로 판단되면 ADC값에 제3오프셋값을 보상하여 산출된 제2모터전류값에 기초하여 제어신호를 출력하는 제어부를 포함하는 모터제어장치에 관한 것이다.
