基于MATLAB和Labwindows/CVI的车辆刹车系统仿真研究

摘要

The property of vehicle brake system affects the safety of driver and passages directly. The paper aims at a certain type of vehicle for the study, and establishes a system prototype of brake process according the dynamic characteristics of automotive, then uses Matlab/Simulink to build a simulation model of the system in the background and uses CVI to build the top control platform. Finally, it verifies the accuracy of the system prototype through simulation. The results of simulation shows that the prototype of vehicle brake system has high accuracy and also shows that the method of this paper used is feasible.%汽车刹车系统的性能直接影响到驾驶员及乘客的安全,文章以某型汽车为研究背景,依据该型汽车在刹车过程中的动力学特性,建立了该型汽车在刹车过程中的系统模型,然后利用Matlab/Simulink对该系统建立后台仿真模型,并通过CVI实现上层仿真控制台,最后,通过仿真实验对该系统模型的准确性进行了验证.系统仿真结果表明所建立的汽车刹车系统模型具有较高的准确性,同时也说明了文中所采用的方法的可行性.
