摘　　要：在Simulink和AMEsim中分别建立了车辆的动力学模型和液压系统模型,采用联合仿真的方法对稳定性进行了模糊控制的仿真研究。根据仿真参数,利用Freescale公司生产的MC9S12xDT512单片机为主芯片,设计了模糊控制器。调试结果表明:所设计的模糊控制器具有调节电磁阀控制信号占空比的功能。The automotive dynamic model and hydraulic system model were established in Simulink and AMEsim. A research on me simulation of fuzzy control of the vehicle stability was conducted by using the associated approach with the two softwares. According to the parameters of simulation, the fuzzy controller was designed by using the singlechip MC9S12xDT512 of Freescale company. Results gained show that the fuzzy controller is valid in adjusting lhe PWM of control signs of electromagnetic valves.
