N2  - This paper presents experimental results of shock mitigation of pedestrians from a frontal crash with a sports utility vehicle (SUV) by utilizing new active hood mechanisms; pop-up hood and extended hood. The pop-up hood mechanism to protect a pedestrian colliding with the hood area of a SUV is proposed and manufactured. Then, the deployment completion time of a whole active hood lift system, which significantly affects the injury sustained is measured and a headform impact test on the hood system is performed to evaluate shock mitigation of the pedestrian head impact. It is shown that using the proposed pop-up hood mechanism, the pedestrian head injury value can be reduced on the hood impact area for both children and adults. In addition, in this work the newly proposed extended hood mechanism is manufactured by considering beneficial aspects of relatively large-sized SUVs to protect pedestrians from collision with the windshield area. It is demonstrated that the proposed extended hood system can provide a much better protection effect for pedestrians compared to direct collision with the windshield only.<p />  <p>Language: en</p>
