Pedestrian passive safety and active safety both develop rapidly, such as new structural hoods/airbags for pedestrian protection and emergency automatic braking/forward collision warning are used in advanced driver assistance system (ADAS). In this study, improved pedestrian passive safety is to obtain optimal hood structural parameters and add an active pop-up hood. Headform impactor, hood model, simplified vehicle and head impaction models were established, and nine key test points were selected for crash simulation tests. After the simulation, the pedestrian protection performance of the initial hood is evaluated and analyzed based on the head injury criterion (HIC) values. Combined with the orthogonal experimental design method, this study acquired the best structural parameters scheme and applied to the active pop-up hood. The validation results show that after applying the optimal structural parameters to the active pop-up hood, the pedestrian protection performance of the hood is improved and the pedestrian passive safety performance of the smart vehicle is enhanced.
