Open Application Trend of High Definition Map for Unmanned Driving
High definition map not only supports the accurate positioning and fine path planning of autono-mous vehicles,assists in improving the perception capability of the vehicle end,but also effectively makes up the performance boundary of sensors to deal with a variety of long-tail scenarios.Therefore,high defini-tion map has become essential for achieving L4/L5 unmanned driving at this stage.However,high defini-tion map belongs to the basic strategic information resources of the country,involving military and national defense security.Therefore,in terms of policy,China requires high definition map to undergo geographic information confidentiality processing before public application and to comply with map review procedures.This leads to many limitations in the expression of elements and attributes in high definition map,as well as a lack of dynamic updating ability,making it difficult to accurately reflect the driving environment informa-tion of vehicles,seriously affecting the safety and stability of autonomous driving,and making it difficult to break through the"last mile"of unmanned driving.We focus on the issues of geographic information se-curity and timeliness in applying high definition maps for L4/L5 unmanned driving.We comprehensively discuss the current situation,practical needs,and challenges of high definition maps application.Based on this,from policy,technology,standards,pilot exploration,and other aspects,we study and analyze the safety and compliance application trend of high definition maps in the commercialization of unmanned driving in China,and provide prospects for map management innovation,large-scale implementation of crowd-source update models,multi-dimensional collaboration,and cross-departmental,interdisciplinary,and cross-industry cooperation that are urgently needed in the process of high definition maps promoting un-manned driving landing in China.
