Simulation Research of Handling Stability of 4WS Vehicle Based on Human-vehicle-road Closed-loop System
Dynamics model of the active four-wheel steering vehicle was established through the study of dynamic characteristics of wheel tires and suspension structures of vehicles.One point preview-follower optimal curvature driver model and test expected trace were combined,the loop simulation model of driver-vehicle-road system was established,and simulation was performed by the model based on MATLAB platform.The results show that lateral displacement tracking performance and handling stability of 4WS vehicles at high speeds are superior to that of ordinary front wheel steering vehicles,more over,choosing a similar F1 runway road with complex closed curve can be more objectively reflect the vehicle handling dynamic characteristics and control effects.
