Abstract

The driving environment of the vehicle has characteristics that the change of position, velocity and distance between vehicles is severe. The performance test of system must be carried out in the real road environments with consideration of the driving environment of vehicles to measure the performance correctly because the performance of vehicular communication systems is affected by the driving conditions of the vehicle. In this paper, we propose the test methods of V2V/V2I performance and V2V multi-hop transmission function and present the test results measured by the vehicular communication systems already developed. In the test result, we confirmed the fact that the distance of communication devices and the driving direction of vehicle are affecting the communication performance. We also confirmed the multi-hop transmission function using the driving vehicle in the limited area as the proposed test method.

차량의 주행환경은 차량의 위치와 속도, 차량 사이의 거리변화가 심한 특징을 가진다. 차량 통신시스템의 성능은 차량의 주행환경에 영향을 받기 때문에, 정확한 성능 측정을 위해서는 실제 도로환경에서 주행환경을 고려하여 시스템 성능 시험을 수행해야 한다. 본 논문은 실제 도로환경에서 V2V/V2I 성능과 V2V 멀티홉 전송기능 시험 방법을 제안하고, 기 개발된 차량 통신시스템으로 측정한 시험 결과를 제시한다. 시험결과를 통해 통신장치의 거리와 차량의 주행 방향이 통신성능에 영향을 주는 것을 확인하였다. 또한 제안된 멀티홉 시험 방법으로 제한된 지역 내에서 주행하는 차량을 활용하여 멀티홉 전송 기능을 확인하였다.
