Abstract
A method of improving the control performance of a traction slip control system so that faulty control activations of the TCS control system are prevented in critical situations such as driving downhill. The invention concerns a method wherein a vehicle reference speed and a vehicle deceleration signal are derived from the rotational behavior of the vehicle wheels and wherein a vehicle deceleration signal is obtained by way of a longitudinal deceleration sensor. The course of the two deceleration signals is compared and analyzed for detecting stable or unstable wheel rotational behavior. Preferably a difference signal is formed indicating the difference between the two deceleration signals. The difference signal is evaluated by a multistage filter arrangement.
