Abstract

Future legislation for pedestrian protection in Europe and Japan considers standardized test methods and test requirements relevant for a type approval. The first phase of legal introduction starts in 2005 and a more stringent second phase will follow in 2010. This paper consists of three main chapters. The chapter “Requirements” starts with a summary of the pedestrian protection-related requirements for head impact and its conflicting requirements for the vehicle handling and driving. The second chapter “Hood Concepts” discusses how the hood design could become compatible with the pedestrian protection requirements. Concepts for the hood design fulfilling both, the European as well as the Japanese requirements are described. The impact of the hood design parameters on the head impact performance are shown and different concept solutions are presented. The third chapter “Hood Hinge Concepts” examines the hinge performance for pedestrian protection in detail. The mounting points of the hood, such as hinges, latches and bumper stops, are the most critical points for head impact. Different hinge concepts and their impact on the head impact performance are shown. The influence of the hinge parameters on the acceleration curves and the HPC values is discussed and conclusions for the hinge design as well as for the vehicle structure are drawn.
