摘　　要：用仿真分析方法 ,对可能用于车距自控系统的跟车模型的稳定性作了分析 .主要内容包括 :选定了 3种可能用于车距自控系统的跟车模型 ;在以通行能力为约束的条件下 ,以前车突然制动与平稳降速 2种典型驾驶行为和行驶车距与车速 2种主要车辆行驶参数 ,对选定的 3种跟车模型作了仿真 .Simulation analyses on stability of car-following models appropriate to automatic safe headway control system are presented in this paper. Main contents are: three car-following models available for automatic safe headway control system are selected; under constraint condition of capacity, three selected car-following models, two typical leader-car drive behavior of suddenly stop and steady deceleration as well as variation of two main traffic parameters of headway and speed are simulated. According to the results of simulation analyses car-following speed-change control model appropriate to automatic safe headway control system is submitted.
