In this paper, testing techniques for electronic single point frontal crash sensing systems are presented. Particular attention is paid to the algorithms used by these modules. First, a description of a new performance measure called the Crash Detector Operating Characteristic (CDOC) is given. Using the Monte Carlo crash testing technique, a quantitative definition of this measure is described. Two new ways of testing single point modules or algorithms are presented. All of these techniques and approaches lead to objective performance measures. Conclusions and recommendations are drawn from the discussion of the new measures.

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.

In this paper we discuss possible applications and design considerations for an Occupant Position Sensing System (OPSS). First, the minimum functional requirements and possible advanced applications for an OPSS are presented. The relation of an OPSS to current and future deployment decision systems is discussed. We then consider the implications of the functional requirements for the choice of technology. Finally, we describe a prototype occupant position sensor, and display its position and motion tracking capability.
