Abstract:
1. A method of determining an optimum performance in a track-type tractor, the method comprising: receiving, at a processor of the track-type tractor, inputs from the track-type tractor related to current operating conditions and a current operating state; calculating in real time a current performance based on the current operating conditions and the current operating state; generating an estimated operating environment using the current operating conditions and the current operating state; iteratively solving, via a processor of the track-type tractor, a performance equation that incorporates the estimated operating environment over a range of values of a single input variable to determine a peak value of the performance equation and a state of the single input required to achieve the peak value, wherein the peak value corresponds to the optimum performance of the track-type tractor; normalizing the current performance to the optimum performance to produce a normalized performance; and providing the normalized performance, the optimum performance, and the state of the single input required to achieve the optimum performance to a device that adjusts the current operating state to improve or maintain a performance of the track-type tractor; and calculating a ground speed using a nominal pull-slip curve as adjusted by a shear modulus factor.
