为了解决汽车行驶中的某些因素引起的失稳问题，在对汽车的失稳原因和控制方法的分析和研究的基础上，设计了以横摆角速度和质心侧偏角为控制量和失稳判据，以车轮的差动制动为控制手段的汽车稳定性控制系统。并分别设计了模糊 PID控制器和神经网络控制器，运用M A T-LAB/Simulink软件在7自由度汽车模型上进行了仿真。结果显示在危险状态下该控制策略能有效保持汽车轨迹对转向操作的跟随，该控制策略可靠有效。

In order to solve the instability problems caused by some factors in the car driving ,on the basis of analysis and research on the vehicle instability causes and control methods ,the vehicle stabili-ty control system is designed ,w hose control amount is yaw velocity and sideslip angle ,w hose control means is braking the wheels appropriately .Designs of fuzzy PID controller and neural network con-troller and simulation are done by MATLAB /Simulink in seven degrees of freedom car model .The results showed that this control method can effectively keep the car track to follow the steering opera-tion in a dangerous state and the method is reliable and effective .
