A traction control system for a vehicle (310) having a number of wheels (312,314,316,318) each independently powered by a motor, comprises sensors for sensing the acceleration of the rotation of each wheel and a control unit to adjust the torque applied to each wheel (312,314,316,318) if the sensed acceleration is indicative of a skid. A control unit may be provided for each wheel (312,314,316,318) and the control units may be networked to exchange wheel acceleration data, for example using a controller area network (CAN). The control units may be operable to provide continuous torque adjustment for the wheels (312,314,316,318). Each control unit may be able to perform traction control independently of other control units in the system according to predetermined rules.
