Abstract
A system and method for controlling operation of an engine during a bog condition is provided. The method allows for monitoring values of a commanded engine RPM signal and of an actual engine RPM signal. The method further allows for determining whether the difference between respective values of the commanded engine RPM signal and the actual engine RPM signal exceeds a predetermined threshold RPM value. An inflection determining step allows for continuing to monitor values of the actual engine RPM signal to determine an inflection RPM point. A varying step allows for controllably varying the commanded engine RPM signal from a predetermined point about the inflection RPM point towards a desired commanded speed value.
