Increased traffic safety depends on the differentiation in warning, steering actuation, braking interventions as well as the possible passive safety measures in critical situations. Continental built up a test vehicle to develop active safety measures based on radar and camera information. The system focuses on rear end collisions and uses next generation automotive CMOS camera and radar technology to avoid collisions or to reduce their impact severity. The paper describes the networking and the benefit of the additional information, generated by sensor fusion in emergency situations. Key aspects are changes in brake preparation and crash adaptation and the influence of the driver's behaviour, compared to conventional beam sensor based safety systems. In the case of higher speeds the system could not avoid the crash but is still able to reduce the severity of the impact. In addition the time between the beginning of the brake intervention and the crash is longer at high relative speeds, so that the driver has plenty of time to recognize the situation and to avoid the possible collision by a steering intervention. This case was tested with speeds up to 130 km/h and it was always possible to pass the obstacle after a reaction time of 1 second.
