1. A method for evaluating the effectiveness of a tractive effort maximizing control system in a wheeled vehicle comprising the steps 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;

    varying creep speed between a minimum value and a selected maximum value while monitoring tractive effort for identifying a maximum available tractive effort;

    enabling the tractive effort maximizing control system and determining the resulting tractive effort; and

    comparing the resulting tractive effort to the maximum available tractive effort to produce a measure of effectiveness of the tractive effort maximizing control system.
