The effectiveness of current available Automated Emergency Braking Systems (AEB) can be improved by adapting the activation and warning times to the current road conditions. In this work, it has been investigated whether the estimation of the global friction potential μG and the wheel-individual friction potentials μR,i is possible so that the accuracy necessary for an AEB can be reached. In addition to existing work, low friction conditions comparable to icy roads as well as mu jump (i.e. pure dry and low friction conditions, changing road conditions) and mu change (i.e. different surface conditions on the right and left side of the vehicle) manoeuvres were investigated. There are promising results, especially during braking manoeuvres. The accuracy of the estimates increases with higher dynamical excitation. However, there were many outliers in the data sets which cannot be explained yet and require further analysis. However, it has to be mentioned that further investigations are necessary before the proposed estimation methodology is qualified to be applied in a safety-critical system like an AEB.
