Abstract
In order to control wheel spin in a vehicle driven by an internal combustion engine, a spin calculator determines the amount of wheel spin and compares this with a target value. If the target value is exceeded, an engine controller reduces engine output demand, for instance by reducing the opening of a throttle. A fuelling controller forms a threshold value which is inversely dependent on the difference between the reduced engine output demand and the actual engine output demand. When the wheel spin exceeds the threshold value, the controller cuts off the supply of fuel for a predetermined pattern of engine fire events.
