ENGINE CONTROL DEVICE FOR HYBRID CONSTRUCTION MACHINERY
The present disclosure relates to an engine control device for hybrid construction machinery, and more particularly, and an object of the present disclosure is to, in a hybrid excavator, in which a swing apparatus is electrically driven by being separated from a hydraulic power train system in the related art, satisfy a minimum rotational speed of an engine auxiliary motor which is necessary to satisfy a target charging amount required for an energy storage device, and improve fuel efficiency by removing unnecessary energy loss at low loads by controlling a rotational speed of an engine to be lower than a rotational speed of an engine determined based on a dial input and a mode input in the related art, in a case where a target power generation amount of the engine auxiliary motor is small in a low-load work situation.
