Abstract

An integrated control apparatus for engine and hydraulic pump in an engine system, the engine system including an engine (10), a hydraulic pump (20) driven by the engine, a control valve (30) for controlling a hydraulic oil discharged from the hydraulic pump and a hydraulic actuator (40) operated by the hydraulic oil from the control valve, includes a power mode determiner (64) calculating an auto mode change index as a function of a first state value representing a work load of the hydraulic pump and a second state value representing a work speed required by an operator to determine whether a current power mode of the hydraulic pump is to be changed, a pump power determiner (67) determining a power mode of the hydraulic pump based on a result of whether a current power mode of the hydraulic pump is to be changed, and an engine speed determiner (66) determining an engine speed based on the result of whether a current power mode of the hydraulic pump is to be changed.
