One of the problems that might occur during acceleration is wheel spin. While the wheels are spinning, the driving force on the tires reduces considerably and the vehicle cannot speed up as desired. lt may even become very difficult to control the vehicle under these conditions. The acceleration characteristics of a vehicle can be improved without changing its physical capabilities with a suitable engine control algorithm that has no additional sensor inputs. This paper presents several control strategies for the wheel slip control problem. The torque output of an engine is modulated to prevent the wheel spin caused by rapid increases in the throttle input. The spark time is varied dynamically to adjust the engine torque and therefore the problem is often referred to as dynamic spark advance (DSA). Variable structure control theory is used for the controller design purposes and simulation results are provided.
