Abstract

The use of Event Data Recorders (EDRs) and digital tachographs in traffic accident analysis is increasing due to government regulations mandating their installation. In the past, accident analysis was often hindered by a lack of objective evidence and uncertainty in estimating driving conditions. However, with the integration of EDRs and digital tachographs, accident investigations have become more scientifically grounded. These devices provide key data such as vehicle speed, engine speed, throttle position, brake status, and accelerator pedal position, particularly when a delta-V exceeds a predefined threshold set by control algorithms. EDRs are integrated into the Airbag Control Unit (ACU) and record pre-crash data from –5.0 seconds to the moment of impact (time zero) at 0.5-second intervals. In this study, EDR pre-crash data are evaluated using vehicle communication signals in a low-speed barrier collision test. Based on the evaluation results, a method for accident analysis using EDR data is proposed. Furthermore, the study addresses reliability issues specific to EDRs in electric vehicles.
