摘　　要：针对当前ABS系统的分析大多集中在少自由度的直线制动方面。采用十一自由度汽车转弯制动数学模型,用MATLAB/SIMULINK建立仿真模型。考虑到此系统的非线性、时变性及工况的不确定性,采用了模糊控制算法,并对防抱死制动系统的制动过程进行了仿真研究。针对模糊控制算法的不足,建立了双模控制器,用传统的PID算法优化模糊控制器。采用的十一自由度的转弯制动模型充分考虑到仿真的复杂度及仿真的可信度,完全反应了制动过程中汽车的宏观运动及微观运动。The majority of the analysis of Anti-Lock Brake system is emphased on few Degrees of Freedom movement on straightaway, It adopts 11 freedom degrees vehicle Swerve brake math model and builds the simulation model by MATLAB/SIMULINK. Considering the nonlinearity, time variant and the uncertainty of work conditions, the fuzzy controller was adopted, which simulated the brake process of ABS and analysed the result. For the shortage of fuzzy controller, the double model controller was adopted, optimizing fuzzy controller through traditional PID controller. The simulation took complexity and reliability into account, giving a clear image of the vehicle macroscopical movement and microscopical movement in brake process.
