基于ADAMS与MATLAB的汽车ABS控制策略的联合仿真

摘要

Based on analysing the ABS simulation technology at present stage,in this paper we build the full vehicle model with ADAMS and the ABS control strategy model and the pressure regulating control unit model with MATLAB.The full vehicle dynamic model and the control model are connected together by the ADAMS/Control module interfaces,and to form an ABS real-time closed-loop control model,fi-nally the co-simulation of them two is realised.We also study the co-simulation of automobile ABS on high-adhesion coefficient road.It is known from the simulation results that the ABS system plays a very good anti-lock braking effect in the braking process of the full vehicle,this verifies the reliability of the ABS braking and the feasibility of the co-simulation method.%在分析现阶段ABS仿真技术的基础上，利用ADAMS搭建整车模型，利用MATLAB搭建ABS控制策略模型以及气压调节控制单元模型。通过ADAMS/Control模块接口将建立的整车动力学模型与控制模型连接起来，组成ABS实时闭环控制模型，最终实现两者的联合仿真。对高附着系数路面的汽车ABS进行联合仿真研究，由仿真结果可知ABS系统在整车的制动过程中起到了很好的制动防抱死效果，验证了ABS制动的可靠性以及联合仿真方法的可行性。
