Pedestrian protection is an upcoming field for research and development. Active pedestrian protection is described from a system perspective. In this view, the development of an active pedestrian protection system is shown. First an overview on statistics and legal requirements is given and the system requirements are discussed. Sensor concepts and realizations are shown, also different test methods and results are explained. FE-simulations to complete and later replace additional tests are developed, after cross check with the experimental results. In combination with the shown actuator concept this leads to a full functioning active pedestrian protection system.

The automotive industry is focusing more on protection of pedestrians and cyclists. Approximately 6000 out of every 35 000 persons killed in traffic accidents annually in the European Union are pedestrians. Therefore the development of passive measures to improve pedestrian safety is strongly supported by the European automotive industry. This paper describes in detail the mechanics and kinematics of an active hood. Furthermore the investigation of the integration and effects of the active hood in a feasible safety concept of modern cars is presented. Additionally, detailed evaluations of real hardware testing and simulation of pedestrian head impact are shown in this paper. The results are discussed, and some new information will be brought up for future strategies in safety concepts for new cars.
