| Abstract: | Based on an established dynamic model of a four-wheel steering (4WS) vehicle, the detailed procedure of dynamic simulation of 4WS steering in Matlab software environment was described. The handling and stability performance both in steady and transient states were investigated. The effects of the control parameters on the performances were examined, and the control parameters were optimized according to the vehicle slip angle minimization. Meanwhile, the simulation results between the 4WS vehicle and the conventional front-wheel steering (FWS) vehicle were compared. The conclusion can be useful for the performance evaluation and control system design for the 4WS vehicles. |
