EDR is one of the functions of ACU that records the event data when a crash occurs. In addition, EDR data is recorded if the crash or recording condition is satisfied. Prior to using the EDR data for traffic accident analysis, the EDR data should be verified whether the data is recorded from a specified situation by using the PDOF results, air-bag deployment status, and ignition cycle. In this study, two EDR analysis cases were covered. The first is that the PDOF results of EDR data differ from the actual damaged point on the vehicle. The second is that the crash point is different from the recorded event time. The accident reconstruction was performed by using PC-Crash based on the EDR data, vehicle damage status, and black box images. We arrived at the conclusions by taking advantage of a reconstructed accident simulation. The first conclusion is that the PDOF results of the EDR data differ from the actual damaged point on the vehicle when the vehicle crashed as it rotated. The reason is that the direction of the vehicle velocity is different from the actual direction on the vehicle. The second conclusion is that the time zero of the EDR data differs from the time of the crash with some other object. The EDR data is recorded when the crash or recording condition was satisfied. In particular, the recording conditions are defined by Delta-V of the longitudinal and lateral directions. So, if the moving vehicle satisfied the recording conditions, the EDR data is recorded even if the vehicle did not crash.
