摘　　要：建立了四轮驱动汽车加速过程的数学模型,采用模糊控制方法,建立了以滑转率为控制对象的汽车牵引力控制系统TCS(Traction Control System),用Matlab的模糊工具箱进行了模糊控制器的设计,并在Simulink仿真环境下进行了动态仿真,结果表明:基于模糊控制的TCS可将驱动轮滑转率控制在最佳值附近,有效地改善车辆的牵引性和动力性,抑制驱动轮过度滑转。A dynamic model on four wheel drive vehicle was established and the Traction Control System （TCS） was realized through rectifying the output torque of engine with the fuzzy control method. The fuzzy logic controller was designed with MATLAB fuzzy control toolbox. The Dynamic simulation has been carried out with SIMULINK, which has shown that the TCS based on fuzzy control can control the driven slip dose to the optimal value, so as to improve the traction performance and prevent the driven wiled spinning effectively.
