Study Findings from China Automotive Engineering Research Institute Co. Ltd. Advance Knowledge in Craniocerebral Trauma (A Hierarchical Prediction Method for Pedestrian Head Injury in Intelligent Vehicle with Combined Active and Passive Safety...).

A recent study conducted by the China Automotive Engineering Research Institute Co. Ltd. explores the effectiveness of a combined active and passive safety system in protecting pedestrians from head injuries in vehicle collisions. The study constructs a "vehicle-pedestrian" interaction system and analyzes the impact of the exterior airbag and braking control systems on pedestrian head injury. The results show that the exterior airbag can effectively protect the pedestrian's head and reduce the head injury criterion (HIC). The study proposes a hierarchical design strategy and a rapid prediction method for HIC, providing a theoretical basis for parameter design and selection. [Extracted from the article]
