Random crosswind affects vehicle handling and stability, increasing the difficulty of driving operation. For crosswind disturbance, active front steering controller based on ADRC（Active Disturbance Rejection Control）technology was proposed base linear two degrees of freedom model, to eliminate crosswind disturbance on motor cars. Closed-loop simulation model of driver-vehicle-road was established in Matlab controls CarSim four vehicle model, and double lane change road simulation test. CarSim and Simulink co-simulation results show: under crosswind disturbance, the ADRC controller can well control the vehicle model to complete the double lane change road simulation test, and the performances of response are better than no wind situation; meanwhile，controller is well to speed adaptability, the model less precision and robustness. AFS (active front steering) controller is effective to resist crosswind disturbance, improve handling and stability and driving safety.
