摘　　要：考虑到车辆弯道制动时车轮垂直载荷的变化影响,建立了8自由度的汽车弯道行驶整车仿真模型。采用模糊控制理论,对车速与轮速的变化、车轮载荷转移的变化以及制动器制动力矩的变化进行了计算机仿真。仿真结果表明,采用模糊控制可以达到很好的制动控制效果,对开发和改进ABS系统有一定的意义。Considering the influence of wheel vertical load, the paper establishes a dynamic model of 8 degrees freedom for an entive vehicle when driving in the crooked roads. Based on this model, the changes of vehicle speed, wheel load and braking torque are simulated by using fuzzy logic control. Thi~ result of simulation shows that a good control effect can be achieved.
