论文摘要
随着运输数字化，新的数字信息服务用例正在出现。例如，在交通信号（尤其是紧急车辆）上的道路使用者的优先级是一个理想的目标。道路用户和C-ITS站之间必要的通信链接的要求通常不足以满足。特别是，增加沟通距离的同时最大程度地减少潜伏期是及时影响流量信号计划控制的关键要求。本文介绍了具有靶向传输方向选择和高天线增益的快速切换天线阵列的汽车应用。除天线设计要求外，还使用无线电传播模拟进行了理论分析以增加传输距离。此外，使用连续波和C-ITS服务测量值在实验室和测试场环境中进行实际评估。从科学的角度实施并讨论了基于地理位置的天线扇区的自动切换。结果，提出了在交通远程信息处理环境中使用自适应天线阵列，以提供更强大的通信链接并增加无线电传输距离。
With the digitalization of transportation new use cases for digital information services are emerging. For example, prioritization of road users at traffic signals, especially emergency vehicles, is a desired goal. Requirements for the necessary communication link between road user and C-ITS station are often inadequately met. In particular, increasing communication distances while minimizing latencies are key requirements for timely influencing the control of traffic light signal programs. This paper presents the automotive application of a fast-switchable antenna array with targeted transmission direction selection and high antenna gain. In addition to antenna design requirements, theoretical analyses to increase transmission distance are performed using radio propagation simulation. Furthermore, practical evaluation is performed both in laboratory and test field environment using continuous wave and C-ITS service measurements. An automatic switching of antenna sectors based on geolocation is implemented and discussed from a scientific point of view. As a result, using an adaptive antenna array in traffic telematics environments is proposed to provide more robust communication links and increase the radio transmission distance.
