Assessment of the flexible pedestrian legform impactor (flex pli-g) as a test tool for legislation on pedestrian protection

Zander, Oliver; Lorenz, Bernd

A new pedestrian legform impactor with biofidelic characteristics (Flex PLI) showed first good test results on real cars in its version 2004. Aim of a research study at the Federal Highway Research Institute (BASt) was to give an assessment of the latest version of this impactor (Flex PLI-G) as a potential instrument for legislation. A series of tests was made on real cars with pedestrian-friendly bumper according to the EEVC test conditions and limits. Furthermore, a comparison with the EEVC Working Group 17 legform impactor was made within a series of tests under idealised test conditions.
