Vehicle Stability Control in Crosswind Environments
To improve the driving safety and stability of vehicles in crosswind environments,a vehicle stability control method for crosswind environments based on an active front steering(AFS)system was proposed.Firstly,the two degree-of-freedom vehicle model,aerodynamics calculation model,and AFS system model were established.Secondly,a vehicle stability controller based on model predictive con-trol(MPC)was designed,which was coupled with the driver by using the AFS system,so as to realize the integrated control of vehicle stability in crosswind environments.Finally,the vehicle stability in crosswind environments under different working conditions was simulated and analyzed.The experimen-tal results show that the designed integrated control system has good lane-keeping ability and obstacle avoidance ability in crosswind environments.However,the controllability of the system decreases when the wind speed increases,and the vehicle is easy to lose control especially when the crosswind changes.
