PlatoonControl and Simulation of Intelligent Connected Vehicles with Time Varying Inter-Vehicle Distance

智能网联汽车的发展是将来智能交通系统中的一个重要方向,受基础设施条件以及试验成本的限制,目前的测试验证仍以计算机仿真为主。针对现有仿真软件难以满足智能网联汽车测试需求的问题,以开源软件PLEXE为基础,通过对其道路交通模拟器中的车辆动力学模型、通信拓扑结构以及车辆队列控制器等关键模块进行二次开发,设计了面向智能网联汽车队列控制研究的可视化仿真平台,对变车距队列控制算法进行仿真验证。仿真结果表明:上述平台可完成队列控制的可视化仿真,相比其它软件更加直观形象。

Intelligent and connected vehicles(ICVs)are recognized as a significant direction for future intelligent transportation systems.However,limited by the present infrastructure and experimental cost,computer simulation re-mains as the main method for the key technology testing of ICVs.As the present simulation software cannot satisfy the testing requirements of ICVs,this paper provides a new ICVs simulation platform based on the re-development of the open source software PLEXE.By modifying the vehicle dynamic model,communication topology and platoon control-ler in SUMO,a visual simulation platform for intelligent network-connected vehicle queue control research was de-signed to simulate and verify the variable distance queue control algorithm.The simulation results show that the plat-form can complete the visual simulation of queue control,which is more intuitive than other software.
