摘　　要：电动汽车因其节能环保的特性,正成为汽车工业未来的主要发展方向,也引发了各方对其进行深入研究的热情。电动汽车由于没有了发动机,故传统液压制动系统不能完全搬到电动汽车上,必须使用电子真空助力器(I-Booster)或者采用线控制动技术。考虑到现有研究多采用单轮车辆模型进行控制算法的简单验证,而单轮车辆仿真模型过于简单,而且还不能反映轴荷变化的影响。本文采用联合仿真分析,利用CarSim和Simulink软件,建立整车和控制器的仿真模型,并通过CarSim中的接口变量进行输入输出设置,从而实现两者的联合仿真。Electric vehicles,due to their energy-saving and environmental protection characteristics,are becoming the main development direction of the automotive industry in the future,which has also sparked enthusiasm for in-depth research from all parties..Because Electric vehicle has no engine,so the traditional hydraulic brake system can not be completely used in electric vehicles,you must use I-Booster or wire-controlled brake technology.Taking into account the single-wheel vehicle simulation model is too simple,and cannot reflect the impact of changes in shaft load.Using CarSim and Simulink software,establish simulation models of the entire vehicle and controller,and set input and output settings through interface variables in CarSim,a co-simulation isdone.
