چکیده:

This paper examines the usefulness of an active front steer system (AFS) which uses added front steer angle for steering intervention in the context of Intelligent Transportation Systems. The resulting moment on the vehicle affects yaw and lateral velocity, there by increasing the steering function. The steering function achieved through AFS is used to control the handling states in severe maneuvers. Because the yaw and lateral characteristics are highly nonlinear, a Fuzzy logic inference system is developed to explore AFS feasibility and capability. Computer simulation results, using nonlinear seven degree of freedom vehicle model are included, and show the remarkable enhancements of the AFS vehicle.
