摘　　要：应用ADAMS软件建立虚拟整车模型 ,在A/View模块中模型被简化为 15自由度。为满足制动研究要求 ,采用UA (UniversityofArizona)模型 ,表达路面与轮胎之间的力学特性。利用MATLAB中的Simulink环境 ,建立ABS控制模型 ,本文采用逻辑门限值控制方法。通过A/Controls提供的接口 ,对整车模型和控制模型进行结合 ,进行虚拟环境下的ABS控制方法的研究 ,并结合道路试验的数据进行分析比较 ,从而为ABS匹配工作探索新的途径。In this paper,a virtual car model was built by using the ADAMS software,In ADAMS/View,the model is simplified with 15 DOFs,it is convenient to build and modify.To satisfy the need of braking,the UA(University of Arizona)model is used to express the force character between the road and the tire.ABS control model was built by using the MATLAB software.In the Simulink,the various control metho ds can be easily applied.The Threshold Method was focused on in this paper.Using the interface provided by A/Controls,Study on ABS control method in virtual environment was carried out.Comparing with road tests,the result in virtual environment was analyzed and was proved to be credible.This paper provides a new method for parameter calibration of ABS.
