摘　　要：随着车联网和无人驾驶技术的不断发展,这两种技术在日常交通领域的应用也不断扩大。而车与车之间(V2V)通信是影响车联网和无人驾驶技术发展过程中的重要因素。当前V2V通信可靠性方面还存在一定问题,特别是相向行驶的车辆之间通信,由于两车辆之间相“接触”的有效时间很短,导致相向行驶车辆间通信链路持续时间很小,可靠性比较差。所以针对上述存在问题,该文提出了一种基于虚拟化的相向行驶车辆之间通信机制,通过Prescan/Matlab仿真结果表明,该虚拟化机制能够增加相向行驶车辆之间通信链路持续时间LDT(link duration time),提高了通信的可靠性,为车联网和无人自动驾驶技术的应用提供了更好的保障。With the continuous development of IOV(internent of vechile)and driverless technology,the application of both technologies in the field of daily transportation is also expanding.While V2V communication is an important factor in the development of IOV and driverless technology.There are still some problems in the reliability of V2V communication in current time.In particular,communication between vehicles moving in opposite directions,in which the time of‘contact’is short.As a result,the duration of communication link between vehicles moving in opposite direction is also small and the reliability of communication is not good.Therefore,in view of the above problems,a communication mechanism between vehicles moving in opposite directions based on virtualization is proposed.Which can add the duration of communication link between vehicles moving in opposite directions and improve the reliability of communication by Prescan/Matlab simulation.It will provide a better guarantee for the application of IOV and driverless technology.
