摘要

车联网系统可以看作是一个复杂的网络物理系统,在未来的智能交通系统中将充分具备协同感知、自适应通信和协同控制的能力。如何构建一套全面的评价体系,使车联网的关键技术能够得到有效的测试和验证,是目前迫切需要考虑的问题。提出了一种基于信息物理融合和硬件在环仿真技术的网联汽车轻量化试验台框架。开发微型车辆作为物理样机,配备Arduino微处理器、ZigBee无线电模块等传感元件。在室内实验室环境下,利用微型车辆对一些典型的合作场景进行了评估。通过物理层与顶层的协同信息交互,可以实现车联网虚拟场景下的同步仿真测量。由于物理节点与仿真节点之间的协调性,该试验台将具有灵活性、可扩展性和实用性。实验结果表明,该试验台是可行的、合理的。本研究对未来开发更多智能网联汽车具有重要意义。

A Lightweight Cross-Layer Cooperative Testbed for Evaluation of Connected Vehicles
The system of connected vehicles can be considered as a complicated cyber-physical system, which will be fully provided with the ability of cooperative awareness, adaptive communication and collaborative control in future intelligent transportation systems. It is now imminent to consider how to construct a set of comprehensive evaluation system so that the key technology of connected vehicles can be effectively tested and verified. In this contribution a lightweight testbed framework for connected vehicles was proposed based on the cyber-physical fusion and hardware-in-loop simulation technology. Miniature vehicles were developed as the physical prototype equipped with Arduino microprocessor, ZigBee radio module and other sensing elements. Some typical cooperative scenarios can be evaluated using the miniature vehicles under indoor laboratory environments. Through collaborative information interaction between physical layer and top layer, the synchronized simulation measurement can be realized in a virtual scenario of connected vehicles. Owing to the coordination between physical nodes and simulated ones, the testbed will be possessed of flexibility, scalability and practicability. Some experimental results presented in this contribution indicate the proposed testbed is feasible and reasonable. This research is beneficial to develop more intelligent connected vehicles in the near future.
