Adaptive Cruise Control (ACC) as first implemented driver assistance system will give the driver the possibility to drive in a convenient manner. The system layout is described as a support system. This implies that the driver has to supervise during operation. Because of today's sensor technology (sensing relevant obstacles - the obstacle itself and the road geometry) the available systems will have restrictions in use. One of the major restrictions is driving under poor weather conditions. Neither radar nor infrared technology is able to fulfil the whole autonomous functionality of driver supervision. This is the reason for the need to detect restrictions of the human being to provide automatic control without adequate possibility for the driver to supervise the system. Because of poor distance estimation of the human being either in good and much more in poor conditions, the driver needs support to ensure safe traffic.
