Abstract

Event Data Recorders (EDR's) have been installed in many motor vehicle since the 1990's. With the advent of sophisticated occupant restraint systems, including belt pre-tensioners and smart air bags, EDR's have recorded an increasing amount of crash-related parameters. Similarly, advanced collision avoidance systems have become prevalent in the vehicle fleet and EDR's are now used to capture a wide range of pre-crash data elements relating to this technology and the resulting status of the vehicle and its control systems. Such data provide a wealth of information related to driver actions, and on the functionality and effectiveness of vehicle safety systems. The current paper will provide an overview of the scope of data elements captured by modern EDR's, will discuss the accuracy and limitations of the recorded information, and will demonstrate the utility of the captured data through case studies of real-world events. The paper draws on research findings from staged collisions and real-world crashes that have been studied by the authors. The data obtained from EDR's in the associated vehicles are compared to either laboratory instrumentation or information captured through conventional investigative techniques. EDR's are shown to provide considerable insight into many aspect of motor vehicle crashes. Their accuracy is confirmed through comparative testing. Similarly, the recorded data are shown to be consistent with the physical evidence of real-world collisions. The benefits resulting from the data captured by EDR's in real-world events are illustrated by means of a series of case studies. EDR's provide a useful adjunct to conventional motor vehicle collision investigation and reconstruction techniques. For many current aspects of vehicle technology EDR's provide invaluable insight into the sensing mechanisms and decision making algorithms used in command and control systems. As motor vehicle safety technologies become more sophisticated and exact greater control over vehicle operation, the availability of comprehensive data related to the operation of these systems will become increasingly important. The lessons learned from early EDR's can be used to enhance the future generations of these systems.
