This paper deals with a system for side-pre-crash recognition for passenger cars. A radar sensor observes the side area of a vehicle detects all objects, measures their distance, radial velocity. In the case when an object trajectory is directed to the own vehicle and becomes dangerous, the radar system deploys safety measures in the own vehicle. The goal is to enhance the occupant safety. In this publication an active safety system to adapt the passenger car's height in case of a precrash-situation is presented. When a hazardous from a side hitting car is detected the height of the own vehicle is increased by 100 mm within 300 ms. This activity is necessary to avoid that the SUVs bumper hits the door, instead of this now it hits the part below the door which is extremely stiff. In consequence the mechanical load to the occupants is decreased dramatically. The complete safety system including sensor and actuators was integrated into a Volkswagen Phaeton. or detecting obstacles and other critical objects a 24 GHz radar sensor is used. The sensor was supplied by Smart Microwave Sensors (SMS) company. The sensor operates with a high sophisticated continuous wave transmit signal. Of cause, the transmit signal is specially designed to be unlimited approvable with respect of frequency regulations (ETSI, RegTP, FCC, etc.). There are no limitations for the commercial use in duration, location and market penetration. The antenna diagram was designed to cover the interesting area for typical side-crash scenarios.
