摘要：

This paper presents the design of integrated control for four-wheel steering (4WS) vehicle. A vehicle nonlinear dynamics model is built based on a lateral dynamics simplified linear model. A more accurate sideslip and yaw rate controller is used for lateral dynamics model of 4WS vehicle. Then a vehicle model based on the individual channel and partial decoupling design paradigm is identified from the vehicle dynamics. The sideslip and yaw rate controller is based on a linear multivariable combined with lateral dynamics model and the front and rear steering angles. The results of a stability analysis and simulations are presented to show that the 4WS integrated control system can markedly enhance good vehicle lateral maneuverability.
