The Research on 4WS Vehicle Steering Stability by Modeling and Simulation

摘要

In order to improve vehicle steering stability, the influence of tire loads and steering svstem to the vehicle stability is taken into account in this paper, and the 4WS vehicle model is established and modeling and simulation research is carried through with the Matalab/simulink. The results point out the differences and characters of vehicle control mode in low speed and high speed. This model provides a method for 4WS vehicle design, improvement and optimization, and also provides reference for 4WS theory research and test check.
