Abstract
A first difference is formed between the speeds of a front left wheel and a rear right wheel. A second difference is formed between the speeds of a front right wheel and a rear left wheel. The higher of the differences is compared with a threshold from a spin threshold generator to provide an indication of wheel spin, which may be used in a traction controller or in an antilock brake system.
