Abstract

본 발명은 건설기계의 유압펌프 제어장치 및 제어방법에 관해 개시한다. 개시된 본 발명은, 엔진에 의해 구동되는 유압펌프의 토출 압력을 제어하는 펌프 제어부를 포함하고, 상기 펌프 제어부는, 엔진 출력 토크 추정값 또는 엔진 회전수에 기초하여 압력 설정값을 산출하는 압력 설정값 산출부, 및 사판각 센서의 고장 여부에 따라 상기 압력 설정값과 압력 지령값 중 하나를 선택하여 출력하는 고장 취급부를 포함한다. 본 발명에 의하면, 압력 설정값을 엔진 출력 토크 추정값에 기초하여 산정하여 그 설정값에 따라 펌프를 제어하게 되므로 사판각 센서의 고장시에도 펌프의 흡수 토크값이 엔진의 최대 토크값을 초과하지 않도록 할 수 있으므로 엔진 고부하 작업 중 사판각 센서가 고장나더라도 엔진 시동의 꺼짐 현상이 방지되게 된다.
