Frontal Oblique Offset Crash Tests
Kineticorp Accident Reconstructionist, William Bortles, discusses our latest research “Performance of Event Data Recorders Found in Toyota Airbag Control Modules in High Severity Frontal Oblique Offset Crash Tests.” Will presented the findings at SAE International‘s 2019 World Congress Event (WCX). A special thanks to Ryan Hostetler for his involvement with the project.
Publication Introduction:
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 paper presents data from a high severity oblique frontal impact test in which the vehicle was struck by a moving deformable barrier. This paper examines the results of EDR data downloaded from two 2015 model year Toyota Highlanders, and the results of EDR reported change in velocity (delta-v), to vehicle mounted accelerometers and reference instrumentation. This paper will analyze EDR performance in reporting:
-
Seatbelt buckle status,
-
Occupant Size Classification, Front Passenger,
-
Airbag and seatbelt pretensioner deployment time(s),
-
Longitudinal delta-v, and
-
Lateral acceleration/crash pulse.
