基于C-V2X直连通信的车辆编队行驶性能优化

 

 

摘要：研究了蜂窝车用无线通信技术（C-V2X）使能的车辆编队行驶。针对直接通信（PC5）模式4通信协议可靠性低的特性，以权衡包可靠性和最终编队串稳定性能的关系为出发点，提出了传输间隔优化与平行驾驶2种性能优化方案，并通过城市交通仿真器（SUMO）进行了仿真验证。结果证明所提方案均能在基于Mode 4的低可靠性传输下实现编队性能的优化。

Abstract：The vehicle platooning technology using cellular vehicle-to-everything (C-V2X) is studied in this paper. For the low reliability of PC5 Mode 4 communication protocol, two performance optimization schemes of transmission interval optimization and parallel driving are proposed based on the relationship between packet reliability and final formation performance. Subsequently, the two schemes are simulated by the traffic simulator——simulation of urban mobility (SUMO). The results show that the proposed scheme can optimize the platooning performance under the low reliability transmission based on Mode 4.
