Performance of Event Data Recorders Found in Toyota Airbag Control Modules in High Severity Frontal Oblique Offset Crash Tests 2019-01-0633
This paper presents an in-depth analysis of the performance of Event Data Recorders (EDRs) found in the Airbag Control Modules (ACMs) as tested in support of the National Highway Traffic Safety Administration’s Frontal Oblique Offset Program. Previous studies have examined EDR performance in high severity full-frontal barrier crash tests and moving deformable barrier side impact tests. This is the first study to present data from a high severity oblique frontal impact test in which the vehicle was struck by a moving deformable barrier. This paper presents the results of EDR data downloaded by two 2015 model year Toyota Highlanders, and presents the results of EDR reported change in velocity (delta-v) to vehicle mounted reference values from NHTSA vehicle mounted accelerometers and instrumentation. This paper will analyze EDR performance in reporting:
• Longitudinal delta-,
• Lateral delta-v,
• Airbag and seatbelt pretensioner deployment time(s), and
• Seatbelt buckle status.
