David E Bullard, Allen D Myers: Method and apparatus for controlling wheel slip on differentially mounted wheels. Caterpillar Tractor Co, Phillips Moore Weissenberger Lempio & Majestic, September 14, 1982: US04349233 (40 worldwide citation)

A standard motor vehicle having a pair of driving wheels (8), (9) powered by a drive shaft (10) through a differential (11) can experience difficulties when one of the two differentially driven wheels (8/9) loses traction. The differential (11) directs all of the power to the wheel that is slipping ...
