自动驾驶中的时空同步问题及一致性要求研究

Study on Spatial-temporal Synchronization and Consistency Requirements in Autonomous Driving

随着人工智能和自动驾驶技术的迅猛发展,自动驾驶汽车正成为未来交通领域的重要趋势。在实现自动驾驶的过程中时空不同步问题在自动驾驶系统的核心算法和处理过程中普遍存在。对自动驾驶时空同步基本问题开展研究,并提出了一种自动驾驶时空一致性要求的概念和体系,提出了针对时间同步、空间同步、自动驾驶决策、自动驾驶控制,以及导航电子地图的更新、交通信息服务以及V2X应用中的数据服务的时空一致性要求。

With the rapid development of artificial intelligence and autonomous driving technology,the autonomous vehicles are becoming significant trends in future transportation.However,in the process of achieving autonomy,the problem of spatial-temporal synchronic is widely present in the core algorithms and processing of autonomous driving systems.The fundamental issues of spatial-temporal synchronization in autonomous driving were investigated.The conceptual framework for spatial-temporal consistency requirements was proposed.Specifically,the requirements were discussed for temporal synchronization,spatial synchronization,autonomous driving decision-making,autonomous driving control,navigation electronic maps update,traffic information services,and data services in V2X applications.
