Zusammenfassung:	The present invention relates to an apparatus and method for controlling a construction machine. An apparatus for controlling a construction machine according to an embodiment of the present invention may compare a fuel efficiency gain expected when engine revolutions per minute (RPM) is decreased with a fuel efficiency gain expected when a current torque curve is changed to a torque curve corresponding to a condition in which auxiliary power is provided and selected from among the plurality of torque curves and then the latter torque curve is selectively applied, based on the fuel efficiency map, and may control an engine by means of a method by which a larger fuel efficiency gain is expected.
