摘　　要：主要研究汽车紧急制动控制及其安全性,在对紧急制动工作过程进行分析的基础上,通过结合Carsim和Simulink软件完成了紧急制动控制。根据两车间的安全行驶距离,采用的模糊控制策略,其输入变量为两车间距及相对速度、输出变量为主缸制动压力。对该制动系统进行仿真实验结果表明,系统的模糊控制策略在制动过程中能有效实现,同时,显著提升了车辆的安全性和乘坐舒适性。This paper mainly studies the emergency brake control and its safety.Based on the analysis of the emergency brake work process,the control of the emergency brake control model is completed by combining Carsim and Simulink software.The input variables of the fuzzy control strategy used are the two-vehicle distance and relative speed,and the output variable is the master cylinder brake pressure.The simulation experiment analysis of the brake system shows that the fuzzy control strategy of the system works well.The brake function is effectively realized,the safety and ride comfort of the vehicle are significantly improved.
