Towards a world-wide harmonized pedestrian legform to vehicle bumper test procedure

  • A biofidelic flexible pedestrian legform impactor (FlexPLI) has been developed from the year 2000 onwards and evaluated by a technical evaluation group (Flex-TEG) of UN-ECE GRSP. A recently established UN-ECE GRSP Informal Group on GTR9 Phase 2 is aiming at introducing the FlexPLI within world-wide regulations on pedestrian safety (Phase 2 of GTR No. 9 as well as the new UN regulation 127 on pedestrian safety) as a test tool for the assessment of lower extremity injuries in lateral vehicle-to-pedestrian accidents. Besides, the FlexPLI has already been introduced within JNCAP and is on the Euro NCAP roadmap for 2014. Despite of the biofidelic properties in the knee and tibia sections, several open issues related to the FlexPLI, like the estimation of the cost benefit, the feasibility of vehicle compliance with the threshold values, the robustness of the impactor and of the test results, the comparability between prototype and production level and the finalization of certification corridors still needed to be solved. Furthermore, discussions with stakeholders about a harmonized lower legform to bumper test area are still going on. This paper describes several studies carried out by the Federal Highway Research Institute (BASt) regarding the benefit due to the introduction of the FlexPLI within legislation for type approval, the robustness of test results, the establishment of new assembly certification corridors and a proposal for a harmonized legform to bumper test area. Furthermore, a report on vehicle tests that previously had been carried out with three prototype legforms and were now being repeated using legforms with serial production status, is given. Finally, the paper gives a status report on the ongoing simulation and testing activities with respect to the development and evaluation of an improved test procedure with upper body mass for assessing pedestrian femur injuries.
