ABSTRACT:
A system and method for evaluating the effectiveness of a tractive effort maximizing control system in a wheeled vehicle utilizes a process of operating the vehicle by applying controlled power to at least some wheels of the vehicle to enable motion of the vehicle, disabling the tractive effort maximizing control system, and varying creep speed between a minimum value and a selected maximum value while monitoring the tractive effort to identify a maximum available tractive effort. Thereafter, the tractive effort maximizing control system is enabled and the resulting tractive effort developed by the vehicle measured. Comparing the resulting tractive effort to the maximum available tractive effort produces a measure of effectiveness of the tractive effort maximizing control system.
