Analysis of the GM Sensing and Diagnostic Module in 360° Linear Momentum Collisions

Delta-v data can be the most valuable data collected by an event data recorder (EDR), especially in a linear momentum reconstruction. This paper discusses how to evaluate an accident reconstruction and compare what the reconstruction indicates to the instruments onboard the crash vehicle, with a primary focus on the delta-v data. Case studies drawn from real-world crashes are reconstructed based on police department files and compared to relevant data collected by the EDR. The EDRs in these case studies had been incorporated in the sensing and diagnostic module of General Motors vehicles. The case studies demonstrate that information collected by an EDR can be used to solidify a reconstruction. Although differences between the calculations and the actual data can be attributed to known factors, a solid understanding of the EDR system is necessary for proper data analysis.
