Abstract
A method, system, and machine for controlling the output of an engine of a machine includes calculating the difference between a measured track slip based on track speed and ground speed and a calculated target track slip depending on track speed and chassis pitch, inputting the difference into a controller to determine a propulsion engine torque limit, and limiting the engine toque to the propulsion engine torque limit plus a steering system input torque.
