AEB曲线特征与驾驶员离位响应关联性分析OA

To scientifically and rationally establish the braking deceleration profiles for integrated braking-collision assessment scenarios,this study proposes a curve simplification method based on"temporal equivalence".Characteristic ranges of braking intensity and braking curve slope were extracted from test data of 24 real vehicles.Combined with simulation tests using the THOR dummy and the THUMS human body model,the influence of braking profile characteristics on driver displacement response was analyzed.The results show that reducing the braking intensity of the AEB curve significantly decreases both the maximum occupant displacement and the steady-state displacement.While the braking curve slope also affects the maximum displacement,it has no impact on the steady-state displacement.The influence of the curve slope on the time required for displacement to reach a steady state varies between occupant models.It has a minimal effect on the THOR dummy,but a significant effect on the displacement response of the THUMS human model.This method provides a theoretical basis for setting test deceleration profiles in integrated braking-collision assessments.
