A control apparatus for a hydraulic excavator comprising:

• an operating amount detection means for detecting operating amounts of operating levers corresponding to actuators for works of a hydraulic excavator;
• a characteristic amount extraction means for extracting a characteristic amount showing a characteristic of operation of a hydraulic excavator on the basis of the operating amount detected;
• a membership function memory means for storing a plurality of membership functions for a fuzzy inference preset corresponding to the characteristic amounts by kinds of work;
• and
• a fitness operation means for operating fitnesses relative to the works of the characteristic amount extracted by applying the operated characteristic amounts to the stored membership functions, characterized by comprising,
• an operating characteristic set value memory means for storing operating characteristic set values preset corresponding to operating characteristics by kinds of work, and
• an operating characteristic output means for outputting fitnesses operated corresponding to a plurality of kinds of work and operating characteristics for controlling a hydraulic excavator on the basis of the operating characteristics set values stored.
