A hydraulic system control apparatus of a construction machine according to various embodiments of the present invention is a hydraulic system control apparatus of the construction machine comprising a driving motor driven by hydraulic pressure supplied from a hydraulic pump and a parking brake fixing the driving motor. The hydraulic system control apparatus comprises: a valve unit supplying release hydraulic pressure for releasing an operation of the parking brake; and a control unit controlling on/off of the valve unit, wherein the control unit can control the valve unit to supply the release hydraulic pressure to the parking brake when manipulation of an operator is detected when the construction device is operated to stop driving. The hydraulic system control system prevents load accumulation to a driving reducer.

    본 발명의 다양한 실시예에 따른 건설기계의 유압시스템 제어 장치는, 유압펌프로부터 공급되는 유압을 통해 구동되는 주행모터 및 상기 주행모터를 고정시키는 파킹 브레이크를 포함하는 건설기계의 유압시스템 제어 장치에 있어서, 상기 파킹 브레이크의 작동해제를 위한 해제유압을 공급하는 밸브부; 및 따라 상기 밸브부의 온/오프를 제어하는 제어부를 포함하고, 상기 제어부는 상기 건설기계가 주행정지 조작된 상태에서 상기 작업기 조작이 감지된 경우, 상기 파킹 브레이크에 상기 해제유압을 공급하도록 상기 밸브부를 제어할 수 있다.
