中欧V2X联合试验关键场景及技术

 

 

摘要：中国和欧洲在车联网（V2X）领域开展联合试验以验证关键场景及技术。以蜂窝车联网（C-V2X）通信在中国和欧洲的发展为背景，重点探讨了中欧V2X联合试验方案、相关性能评价指标，以及已有测试结果。探讨了支持车辆速度适配、智能交通路口、自动驾驶这3大关键测试场景所需要应用层面的消息实现。认为车路网间有效信息交互是实现这些场景的关键因素。联合试验中将在系统层面进一步验证比较测试场景内信息交互性能指标。

Abstract：China and Europe have initialized the trial cooperation on Vehicle-to-Everything (V2X) key scenarios and technologies. Using the current progress of Cellular-V2X (C-V2X) development in both regions as the background, the selected joint test scenarios, related key performance indicators, and the current test results are described in this paper. The key test scenarios are green light optimal speed advisory, intelligent intersection, and automated driving. The implementation of the messages at the application layer to support the test scenarios is discussed. The effective information exchange among the vehicle, road infrastructure, and mobile network are the key to realize these key scenarios. The joint V2X trials between China and Europe will further evaluate and compare at the system level the information exchange performance in test scenarios.
