摘要: 随着自动驾驶技术的发展,传统的地图服务已经不能满足以机器为主体的自动驾驶车辆的需要。具有更高精度、更多要素、更快更新频率的高精地图成为自动驾驶车辆的关键。不同来源数据之间的交互是高精地图用于自动驾驶导航决策的保证。针对智能网联汽车系统中高精地图的数据交互问题,本文首先对相关的研究进行了分析,依据高精地图的数据内容和数据来源对智能网联汽车中的高精地图数据进行再组织;然后详细阐述了基于车-路-云三方的高精地图数据交互的内容和交互机制,形成一个适用于智能网联汽车的高精地图数据交互模式;最后在仿真环境下对设计的数据交互模式进行了验证。

Abstract: With the development of autonomous driving technology, traditional map services can no longer meet the needs of autonomous vehicles with machines as the main body. A high-definition(HD) map with higher accuracy, more elements, and faster update frequency has become the key to autonomous vehicles. Analyzing the data interaction issues concerning HD maps in intelligent connected vehicle systems, this research examines relevant studies and reorganizes the HD map data in intelligent connected vehicles based on the data content and sources of HD maps. Furthermore, it elaborates on the content and interaction mechanism of HD map data exchange based on the “vehicle-road-cloud” communication framework, forming an applicable HD map data interaction model for intelligent connected vehicles. Finally, the designed data interaction model is validated in a simulation environment.

Key words: high-definition map, vehicle-road-cloud, data interaction, protocol buffer
