ABSTRACT:
A machine includes an electric drive propulsion system including an internal combustion engine, an alternator, a motor controller, and at least one electric motor. The machine further includes an electronic controller in communication with the electric drive propulsion system. The electronic controller is configured to determine, in chassis, and store a lugging horsepower of the engine at a plurality of different engine speeds. The machine further includes a memory for storing the lugging horsepower for each of the plurality of different engine speeds corresponding to lug curve data. The electronic controller is further configured to affect a control decision based on the lug curve data.
