摘　　要：随着我国汽车行业的快速发展,小轿车已经成为了普通家庭的标配,私家车的普及为我们的出行带来了极大的方便。在享受汽车带来的生活便利的同时,交通事故带来的人民生命、财产损失却不容忽视,因此,汽车主动安全性受到越来越广泛的关注。文章利用Carsim软件进行整车建模,利用Matlab/Simulink软件搭建电动小汽车的主动避撞控制策略以及仿真模型包括加速/制动切换模型、电机逆模型、制动系逆模型。最后将各个模块连接在一起,形成了Matlab/Simulink与Carsim的闭环联合仿真系统。With the rapid development of China’s automobile industry,car has become the standard for ordinary families,and the popularization of private cars has brought great convenience for our travel.While enjoying the conveniences brought by the automobile,the people’s life and property loss caused brought by the automobile can’t be ignored.Therefore,the active safety of the automobile is paid more and more attention.In this paper.Carsim software was used for vehicle modeling,and Matlab/Simulink software was used to build the active collision avoidance control strategy of the electric car as well as the simulation model,including the acceleration/braking switching model,the motor inverse model and the braking system inverse model.Finally,the modules are connected together to form the closed loop joint simulation system of Matlab/Simulink and Carsim.
