A traction control system is provided for controlling wheel spin of a vehicle. The amount of wheel spin is determined for each driven wheel and compared with a threshold. When the threshold is exceeded, drive to the driven wheel is immediately reduced by a predetermined amount. Drive is restored as soon as the wheel spin is brought under control.

Method of and apparatus for controlling wheel spin

A traction control system is provided for a vehicle having driven wheels driven via a limited slip differential. The amount of wheel spin of each driven wheel is compared with a threshold to detect excessive wheel spin. If excessive spin is detected for both driven wheels, an engine management system reduces the demand output of a vehicle engine. If excessive wheel spin is detected for only one of the driven wheels an engine output greater than the reduced demanded output is demanded so as to allow the limited slip differential to transfer torque to the other driven wheel.
