摘　　要：为提高电动汽车的安全性,详细分析了电动汽车纵向控制过程,构建了车辆安全距离模型,结合实际避撞需求设计了纵向控制器,并利用Matlab软件对设计的电动汽车主动安全避撞控制方法进行仿真分析.结果表明:提出的电动汽车主动安全避撞控制方法可满足车辆安全避撞需求,控制方法合理有效.In order to improve the safety of electric vehicles,the whole process of vertical control of electric vehicles is analyzed in detail,and a vehicle safety distance model is constructed in this paper.Based on the safe distance model,the longitudinal controller is designed according to the actual collision avoidance requirements.Finally,MATLAB software is used to simulate and analyze the active safety control method of electric vehicle designed in this paper.The results show that the proposed control method can meet the requirements of vehicle safety and collision avoidance,which shows the effectiveness and rationality of the control method.
