Abstract :
Since a minimum 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 an estimation method for the actual wheel-rail friction coefficient whose knowledge is indispensable in the design and implementation of an antislip braking control algorithm. The proposed method is based on an adaptive observer scheme. The estimation algorithm is tested through simulation examples
