Abstract:
A method of determining wheel slippage in a work vehicle includes the steps of: sensing an absolute ground speed of the work vehicle; calculating a ground speed of the work vehicle using at least one drive train component; comparing the absolute ground speed with the calculated ground speed; generating a scaling factor based upon the comparison; and adjusting the calculated ground speed using the scaling factor. The method may also include the steps of scaling the absolute ground speed to a threshold value; comparing the calculated ground speed with the threshold value; and engaging a differential lock if the calculated ground speed is greater than the threshold value.
