HYDRAULIC PUMP CONTROL APPARATUS FOR CONSTRUCTION EQUIPMENT AND CONTROL METHOD THEREOF
Disclosed is a hydraulic pump control apparatus and method for using the maximum working horse power of an engine. The provided hydraulic pump control apparatus for construction equipment, according to the present invention, comprises: a first hydraulic pump; a first hydraulic actuator driven by the hydraulic oil of the first hydraulic pump; a first control valve installed on the fluid channel of the first hydraulic pump; a second hydraulic pump connected to a power take-off apparatus of an engine; a second hydraulic actuator driven by the hydraulic oil of the second hydraulic pump; a second control valve installed on the fluid channel of the second hydraulic pump; a pressure sensor that detects the pressure of the second hydraulic pump; a regulator that controls the amount of oil discharged from the first hydraulic pump; and a controller that computes a horse power value using the detected pressure value of the second hydraulic pump and the amount of oil discharged from the second hydraulic pump and inputs a control signal to the regulator to discharge an amount of oil that corresponds to the difference between the maximum working horse power value of the engine and the computed horse power value of the second hydraulic pump.
