| Abstract: | The stability of high-speed vehicle under side wind is directly connected with the safety of vehicle and passengers.In order to analyze the impact of side wind upon vehicle,A 3-DOF nonlinear vehicle dynamic model considering side wind was established.A Model Reference Adaptive Control(MRAC) method based on BP Neural Network(NN) was applied to active 4WS,which was used to control the front wheel and rear wheel steering angle,then the controlled vehicle should follow the reference model.Simulation results showed that the active 4WS could effectively improve vehicle dynamic response performance and enhance vehicle stability under side wind. |

| Keywords: | active 4WS high-speed vehicle side wind stability control NN |
