Since in a braking operation the shortest possible brake distance is required at all times an efficient and robust slip prevention control must be developed. The aim of this paper is to present a control strategy based on an estimation method for the actual wheel-rail friction coefficient. The proposed control procedure does not use measured values of the slip ratio. The estimation method is based on an adaptive observer design. The proposed logic based scheme estimates a set point that prevents wheel-slip and provides a suitable control to maintain the system at the prescribed set point. If external conditions change a new set point is estimated corresponding to the current situation,
