Abstract
This is a method and apparatus for operating a transfer case of a four wheel drive vehicle wherein sensors detecting rotation of the front and rear drive shafts speed are scaled to produce an advantageously accurate representation of vehicle speed. The method generates a scaling factor by comparing stored information to information sensed by rotational sensors on the front and rear drive shaft.
