Development of test procedures and performance criteria to improve compatibility in car frontal collisions

Compatibility is now generally recognized as the next big step forward for car occupant secondary safety. The work performed to date has focused on the structural performance of vehicles, with the aim of providing a safe environment for the protection of the occupants in which intelligent restraint systems of the future could operate. This paper outlines the present understanding of compatibility for frontal impact collisions and reports the current state of development of three possible test procedures to address the fundamental issues, namely: structural interaction, frontal stiffness matching and passenger compartment strength. Recent advances in the development of a deformable barrier face for the full width test to assess structural interaction, using high-resolution load cell wall measurements, are described. Analysis of the load cell wall data collected in EuroNCAP tests, to address the frontal stiffness problem, is reported together with initial work to investigate the repeatability of the passenger compartment strength test. In addition, for some of these tests possible performance criteria are suggested. This research is being carried out in cooperation with the European Enhanced Vehicle- safety Committee (EEVC) and the International Harmonization of Research Activities (IHRA) Working Groups, and is funded by the Department for Transport, Local Government and the Regions (DTLR).
