Abstract (en)
The present disclosure relates to an apparatus for controlling a hydraulic circuit of construction equipment. According to the apparatus for controlling a hydraulic circuit of construction equipment according to the exemplary embodiment of the present disclosure, a flow rate of a first pump may be provided early to a front working apparatus when traveling and working are required at the same time, and as a result, it is possible to advance a point in time at which the front working apparatus actually begins to operate. In addition, according to the apparatus for controlling a hydraulic circuit of construction equipment according to the exemplary embodiment of the present disclosure, it is possible to mitigate an impact caused by a reduction in traveling speed by controlling a spool of a control valve 20 in accordance with a control map.
