基于MATLAB/Simulink的汽车ABS建模与分析

Modeling and analysis of the vehicle ABS based on MATLAB/Simulink

阐述了汽车防抱死制动系统(ABS)的工作原理,依据动力学的理论,在:MATLAB/Simulink模块中构建汽车ABS的数学模型,并在模型中加入PID调节环节。分析不同路况下车轮的滑移率与附着系数的关系,得到最佳滑移率。以保持最佳滑移率为目标对ABS模型进行仿真分析,利用汽车动力学的基本理论对所得结果进行评价。

Expound the working theory of vehicle anti-lock braking system（ABS）.With the theory of dynamics,the vehicle ABS mathematical model is established in MATLAB/Simulink module,and the PID regulator is added in the model.Analyse the relation of wheel slip rate and adhesion coefficient under the different road condition,obtain the optimum slip rate.The ABS model is simulated and analysed with the target is maintaining the optimum slip rate.Results are evaluated with basic theory of vehicle dynamics.
