Predictive Safety Systems are intending to increase the safety of all road users by mitigating or avoiding collisions. This paper discusses different radar sensors and their combination which are suitable to adapt restraints for predictive safety systems in a most effective way. Sensors which have been considered are the most relevant ones for high volume market penetration: long range radar and short range radar sensors. The sensors have been evaluated for different functions, like Pre-set, Pre-fire and Collision Mitigation. The performed evaluation of radar sensors for a combination of different predictive safety and pre-crash functions, Pre-set, Pre-Fire and Collision Mitigation resulted in the following proposals. A usage of sensors of the same kind provides good performance for a combination of the functions Pre-set / Pre-fire (with 2 x SRR) or Pre-fire / Collision Mitigation (with 1 x LRR). But, only one radar sensor technology is not able to cover all scenarios, urban, country road and highway. To cover all functions Pre-set, Pre-fire and Collision Mitigation in all scenarios a sensor configuration and data fusion of both radar sensor technologies, with 1 x LRR and 2 x SRR, is necessary. In further investigations other sensor technologies like CMOS-Video-Cameras and Lidarsensors can be taken into account. These technologies are still quite high in costs but would give additional measurements to support the reliability and effectiveness of predictive safety and pre-crash functions.
