Exploratory Analysis of Pre-Crash Sensing Countermeasures 2006-01-1438

This paper presents results from an exploratory analysis of pre-crash sensing countermeasures. This analysis consists of a technology review, development of a methodology to estimate safety benefits based on the total harm concept, identification of crashworthiness scenarios and their harm units, and estimation of safety benefits for brake assist and driver seat position adjustment. Using 1996-2003 Crashworthiness Data System databases, crashworthiness scenarios and harm units of passenger cars are identified from a crash analysis of all single event frontal impacts by combining codes from six variables: frontal impact offset, air bag deployment, seat belt use, driver weight, seat track position, and Delta V. Preliminary results show that brake assist and driver seat position adjustment have the potential to reduce the total harm of passenger cars involved in rear-end crashes.
