摘　　要：建立汽车的1/4车二自由度动力学模型,利用模糊控制工具箱设计了用于汽车半主动悬架的模糊控制器,通过应用MATLAB/Simulink对比仿真,结果显示传统的被动悬架在行驶平顺性方面不如使用模糊控制器的半主动悬架,应用模糊控制的半主动悬架系统可以有效提高汽车的行驶平顺性。The two-degree of freedom model of vehicle suspension is established,then the designing way of automobile the semi-active suspension with fuzzy controller is introduced in fuzzy system .A comparative study is carried out lhrongh simulation by using MATLAB/Simulink. It shows that the performances of the semi-active suspension with fuzzy controller are much better than that of traditional passive suspension in the ride comfort. The results show that using fuzzy control can realize the improvement of riding comfort,
