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.
