Abstract

Existing test procedures assessing vehicle interactions with a pedestrian have generally been limited to subsystem impactors. The complex kinematics of vehicle-pedestrian impacts necessitates test surrogates that possess whole-body response capabilities. This paper reports on the activities of an international task group working to develop a recommended practice for pedestrian dummy performance. The objective of the task group was to develop a performance standard for a research dummy based on existing technology. Potential applications include the study of pedestrian kinematics, injury prediction, and the evaluation of countermeasures including active systems. Specifications focus on the 50th percentile male for primarily lateral impacts in the range of 30 km/h to 50 km/h. Development of the specifications included a detailed review of the literature and evaluation of existing dummies including the Hybrid III and the POLAR II. Based on these studies, biofidelity priority was given to whole body kinematics, as well as head, knee, leg, and thoracic impact response. Biofidelity requirements for whole-body kinematics were developed from cadaveric impacts with a late model vehicle. The specification also includes component response corridors for the head, leg, knee, and chest. In addition to the biofidelity evaluation, testing at facilities around the world was performed to evaluate durability, usability, and repeatability of existing dummy technology.
