-In this paper, tradeoffs and testing of frontal crash sensing systems are presented. First, an overall description of distributed and single point sensor systems is given. The differences between the two system configurations is presented. The sensor design would include an algorithm for a single point sensor. Tradeoffs associated with the various configurations and algorithm designs are developed to quantify the performance of any system. Testing techniques are then discussed to help determine the effectiveness of a given sensor system design. Finally, misconceptions throughout the industry are clarified in an objective manner.
