The Analysis of Handling Stability and Virtual Reality Simulation of Four-Wheel-Steering Vehicle

Abstract:

With the building and analysis of 2 DOFs linear model of vehicle ,the keeping at zero of body sideslip angle is regarded as the control target of four-wheel-steering(4WS) to conduct the simulation and analysis of its handling stability in Simulink. There are many methods and parameters to evaluate handling stability. In this paper,one kind of double-move-line performance is used to do the evaluation.In order to make the result more intuitive,virtual reality toolbox in MATLAB are used to link the data in Simulink and the virtual world built by V-Realm Builder,which display the transient response of 4WS in high speed when it is in the emergency of obstacle avoidance .For the purpose of evaluation of handling stability,a front-wheel-steering(2WS) model is built to present a comparison to 4WS.
