An anti-wheel spin system with a high dynamic behaviour is introduced to improve the traction of a commercial vehicle. If one wheel is spinning the pneumatic brake of this wheel is applied. Should this not be sufficient or should two driven wheels spin, the engine torque is reduced. The engine torque can be influenced by means of an electric signal, either through electronically controlled diesel injection, and electric servo motor or a magnet valve with a pneumatic cylinder. The pneumatic cylinder has a very quick response which prevents high initial wheel slip rates. This increases the driving stability. According to the present state of the art, a simple pneumatic cylinder actuates the injection system in a rough manner. To improve this short coming, an intelligent control system is introduced which combines the fast response of a pneumatic system with an accurate displacement control. Both effects contribute to an increased traction control. The system has a high riding comfort due to small variations of the engine speed. The philosophy of the system is explained and test results are shown.
