  • Patent number: 7891182
    Abstract: A method for controlling an engine in a work machine includes determining a base engine operating limit; determining a hydraulic system load on the engine; calculating a modification value for the base engine operating limit; generating a modified engine operating limit based on the modification value and the base engine operating limit; generating an engine control signal based on the modified engine operating limit; and transmitting the engine control signal to operate the engine at the modified engine operating limit to thereby supply additional power from the engine to the drive train to at least partially compensate for the hydraulic system load.
