Abstract
A machine includes a plurality of torque consuming devices drivingly coupled with an internal combustion engine. The plurality of torque consuming devices includes a continuously variable transmission coupling the internal combustion engine with a plurality of ground engaging elements. An electronic controller is in communication with the internal combustion engine and the plurality of torque consuming devices and is configured to execute a torque load control algorithm for generating a torque load limit based, at least in part, on an engine underspeed value. The electronic controller identifies a potential engine stall event during which a current engine speed of the internal combustion engine drops below the engine underspeed value by a predetermined amount, and executes a transient torque load control algorithm to adjust the torque load limit responsive to the identification of the potential engine stall event.
