Research on Vehicle Stability Control Considering Crosswind

本文主要研究基于侧风干扰下的主动前轮转向(AFS)汽车稳定性控制。首先建立车辆八自由度整车动力学模型和受侧向横风扰动作用的侧风模型,其次分析典型工况下的车辆耦合运动状态变化规律,在此基础上提出主动转向汽车稳定性控制策略。最终基于Matlab/Simulink软件搭建整车稳定性控制仿真平台,进行多种工况下的侧风扰动仿真,仿真结果表明推荐的控制策略稳定性控制效果良好。

This paper mainly studies the stability control of active front wheel steering vehicle based on crosswind disturbance.Firstly,the eight-degree-of-freedom vehicle dynamics model and crosswind model affected by lateral crosswind disturbance are established.Secondly,the change law of vehicle coupling motion state under typical working conditions is analyzed,and on this basis,the stability control strategy of active steering vehicle is put forward.Finally,based on Matlab/Simulink software,a simulation platform for vehicle stability control is built to simulate crosswind disturbance under various working conditions.The simulation results show that the proposed control strategy has good stability control effect.
