队列行驶，即汽车自动跟随它们的领导者形成公路列车的想法，具有巨大的潜力来提高交通流效率，最重要的是，道路交通安全。无线通信是一个基本的构建块-它需要管理和维护排。为了保持系统的稳定，必须满足更新频率和通信可靠性方面的严格约束。我们调查不同的通信策略，明确考虑到控制器的要求，利用同步通信时隙以及发射功率自适应。作为一个基线，我们比较了所提出的方法，以两个国家的最先进的自适应信标协议，已被设计用于合作意识的应用程序，即ETSI DCC和DynB。我们的仿真模型已被参数化，并通过真实世界的实验验证。我们的研究结果表明，同步通信时隙与发射功率自适应的组合是非常适合合作驾驶应用，即使在非常拥挤的高速公路的情况下。
Platooning, the idea of cars autonomously following their leaders to form a road train, has huge potentials to improve traffic flow efficiency and, most importantly, road traffic safety. Wireless communication is a fundamental building block – it is needed to manage and to maintain the platoons. To keep the system stable, strict constraints in terms of update frequency and communication reliability must be met. We investigate different communication strategies by explicitly taking into account the requirements of the controller, exploiting synchronized communication slots as well as transmit power adaptation. As a baseline, we compared the proposed approaches to two state of the art adaptive beaconing protocols that have been designed for cooperative awareness applications, namely ETSI DCC and DynB. Our simulation models have been parameterized and validated by means of real-world experiments. Our results demonstrate that the combination of synchronized communication slots with transmit power adaptation is perfectly suited for cooperative driving applications, even in very crowded freeway scenarios.
