In order to investigate the protection effect of automatic emergency braking(AEB)system and active pre-tensioner seat belts in frontal collision,an occupant restraint system model with AEB function and active pretensioner seat belts was constructed based on a certain car model;frontal 100％overlapping rigid barriers collision of simulation experi-ments were carried out for three groups of different protection strategies(without AEB and no pretensioner seat belts,with AEB and no pretensioner seat belts,and with AEB and pretensioner seat belts).The simulation results show that the average Weighted Injury Criteria(WIC)value of the occupants increased by 79％with AEB only,while the average WIC value of the occupants decreased by 9％with the coupled effect of AEB and active pretensioner seat belts.With the active pre-tensioning seat belts in combination with the AEB system,the level of occupant protection can be effectively im-proved.
