Abstract :
The authors have adopted a time delay control method to roundly analyze vehicle dynamic capability equipped with four wheel steering based on close-loop driver vehicle system, especially, driver´s steering behavior tends to become more discontinuous while performing an activity during driving. The single-loop quasi-linear driver steering model can certainly be applied to modeling of a 5 DOF vehicle coupling system. To quantify vehicle performance, the steering control is obtained by step input as the steering angles of the front/rear wheels. The simulation result indicates that the proposed method is very effective in the performance of the vehicle maneuverability at low speed and stability at high speed.
