Description:
A restraint protection system for front row occupant is designed according to the collision danger level. An algorithm based on driver response time margin is designed to determine the danger level of collision. The algorithm gives different possibility of collision, corresponding to different danger level, and corresponding starting different constraint protection device. The simulation model of automobile frontal collision was established in the dynamic simulation software MADYMO and verified by experiment. Compared with the traditional occupant restraint protection system, the simulation results show that the proposed active restraint protection system improves the protection effect of the occupant’s head and hip, while the damage evaluation indexes such as peak neck bending moment, chest acceleration and chest compression decrease obviously. Therefore, the designed active occupant restraint protection system can effectively reduce the degree of occupant injury.
