Abstract

본 발명의 일 측면에 따른 건설기계의 동력제어장치는 유압펌프(20)와 연결되어 상기 유압펌프(20)를 구동시키는 엔진(10); 및 입력된 엔진 목표회전속도로부터 산출된 엔진 최대토크에 대한 상기 엔진의 부하토크의 비율로 정의되는 엔진 부하율을 산출하고, 상기 엔진이 상기 목표회전속도로 구동되도록 상기 엔진 부하율에 따른 엔진 회전속도 지령치를 산출하여 상기 엔진에 출력하는 제어부(60)를 포함한다. 본 발명의 다른 일 측면에 따른 유압펌프 제어장치는 엔진(10)에 의해 구동되는 유압펌프(20)를 제어하기 위한 것으로서, 상기 유압펌프(20)의 사판각을 가변시켜 상기 유압펌프(20)의 소요마력을 가변시키는 마력조절유닛(30); 상기 유압펌프(20)로부터 토출되는 작동유의 부하압력(Pd)을 감지하기 위한 압력센서(50); 및 상기 압력센서(50)에 의해 감지된 부하압력(Pd)으로부터 목표 펌프소요마력을 산출하고, 상기 유압펌프(20)의 소요마력이 기설정된 시간(Δt) 동안 상기 목표 펌프소요마력에 점진적으로 근접하도록 상기 마력조절유닛(30)을 제어하는 제어부(60)를 포함한다.
