Abstract: [Objective] To conduct research on the active front wheel steering control system and improve the steering performance and safety performance of automobiles. [Method] An ideal two degree of freedom model of the vehicle was established using Simulink, and an active front wheel steering system was constructed based on sliding mode control theory. The controller performance simulation experiments were conducted using a joint simulation environment of Simulink and Carsim, with vehicle speeds of 40 km/h, 80 km/h, and 120 km/h, and a ground adhesion coefficient of 0.8. [Result] The additional front wheel steering angle provided by the active front wheel steering controller can make the actual yaw rate closely follow the ideal yaw rate without significant shaking. [Conclusion] The active front wheel steering controller is of great significance for improving vehicle stability and can provide theoretical guidance for the development of AFSS controllers.
