Curve sensors used in first generation ACC (Adaptive Cruise Control) systems are based on steering angle sensors, lateral accelerometers or yaw rate sensors. The disadvantage of these curve sensors is that they do not have any preview characteristics. This leads in many driving situations to misinterpretations by the ACC system, e.g., wrong path assignments of vehicles ahead because of non-constant curve radii particularly in the beginning and ending of curves. The consequence is that the ACC car brakes due to vehicles in adjacent lanes or it ignores relevant obstacles. A second generation ACC system is presented whose curve sensor is realized by a real-time image processing system with the support of a GPS-(Global Positioning System-)based navigation system. This multi-sensor fusion system is suitable for collision avoidance and stop and go applications.
