APPARATUS AND METHOD FOR CONTROLLING PUMP OF HYBRID CONSTRUCTION EQUIPMENT

摘要

The present invention relates to a device and a method for controlling a pump of hybrid construction equipment. The present invention matches the controllability for a turning-combined motion to be similar to hydraulic construction equipment by reducing the flow rate of a pump in proportion to the speed of a turning motor in turning, and the total output of an operation device to be similar to the hydraulic construction equipment by changing a power shift control logic to maintain the sum of a turning driving output and a pump output below the rated output of an engine.
