【Abstract】Thevehicle AEB system can significantly improve the safety of the vehicleduring driving.Therefore，the researchontherelated technologiesandcontrolstrategiesof theAEBsystem hasimportantpractical significance.This paper introduces the working principle of the AEBsystem，thecompositionand functions of each part，and studies and analyzestheAEBsystem test methodsathomeandabroad;compares theexistingsafetydistance model，andoptimizes the control strategydesign basedonthe ideaof hierarchicalcontrol;further selectstheactualvehicle parameters ofacertain passenger car，determines thereasonable model parameter values，and buildsa Carsim/Simulink joint simulation model; finally，acording tothetestrequirementsspecifiedbyC-NCAP（O18version），theestablished hierarchical control strategyissimulatedunderthreetypicalworkingconditionsof thevehicletoverifyitsefectivenessinprecisecontrolof thewholevehicle.
