High-definition map data interaction mode for intelligent connected vehicle

doi:10.13474/j.cnki.11-2246.2024.0219

Abstract

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
