侧风干扰下重载车辆主动防侧翻控制OA

To mitigate high rollover risks of heavy-duty vehicles experiencing coupled disturbances from varied loads and crosswinds,this paper develops a coordinated differential braking-active steering control strategy.It integrates a lateral load transfer rate(LTR)threshold trigger mechanism with driver behavior classification.The system builds a differential braking model for the Electronic Stability Program with load-adaptive control through dynamic LTR thresholds.Fuzzy C-means clustering processes 180 driving behavior datasets to categorize driver types,while sliding mode control dynamically adjusts steering gain.These elements build a human-vehicle-environment integrated lateral stability control framework.Hardware-in-loop experiments demonstrate the strategy's effectiveness in suppressing crosswind interference.Under aggressive driver inputs(305(°)/s)during fishhook/double lane-change maneuvers,the centroid sideslip angle decreases by 31.4%,the yaw rate by 38.1%,and lateral acceleration by 35.4%respectively.On low-adhesion surfaces(road adhesion coefficient Mu=0.45),the lateral load transfer rate remains stable within safe thresholds,with an average reduction of 30%across all lateral stability parameters.The coordinated control approach markedly enhances vehicle stability across varied operating conditions.
