摘要： Disclosed are a hydraulic pump control apparatus and a hydraulic pump control method of a construction machine. The hydraulic pump control apparatus includes a pump control unit for controlling a discharge pressure of a hydraulic pump driven by an engine. The pump control unit includes: a pressure setting value calculating unit configured to calculate a pressure setting value based on an engine output torque estimating value or an engine RPM; and a breakdown treating unit configured to select one of the pressure setting value and a pressure command value according to a breakdown of the swash plate angle sensor to output the selected value. Since the pump is controlled according to a pressure setting value obtained by calculating the pressure setting value based on the engine output torque estimating value, the absorption torque value of the pump does not exceed the maximum torque value of the engine even when the swash plate angle sensor breaks down. Accordingly, a phenomenon of stopping the engine can be prevented even if the swash plate angle sensor breaks down during a high-load operation of the engine.
