Engine control device for hybrid construction machinery
The present invention relates to an engine control device for hybrid construction machinery. More particularly, the purpose of the present invention is to improve fuel efficiency by removing unnecessary energy loss at low loads in a case where a target power generation amount of an engine auxiliary motor is small in a low-load operation situation of a hybrid excavator in which a rotary device is separated from a conventional hydraulic power transmission system so as to be electrically driven, and the rpm of an engine is controlled to be lower than the rpm of a conventional engine that is determined from a dial input and mode input so as to satisfy the minimum rpm of the engine auxiliary motor which is necessary to satisfy a target charging amount required by an energy storage apparatus.
