In this paper the possibility to predict vehicle
control loss using information about the host vehicles states and the road ahead is investigated. An introduction to conventional yaw stability control is presented and a threat assessment algorithm is proposed that can be used in an active safety system to e.g either issue earlier yaw control interventions or completely autonomous maneuvers in order to keep the vehicle on the road. In addition an experimental assessment in which a vehicle equipped with yaw stability control is driven on a test track is presented. It is shown that it is possible to predict
powerful understeer situations if the future geometrical path of the vehicle is known.
