基于UWB/DGNSS的高速公路车辆精确定位方法的研究
Study on the Accurate Location of Highway Vehicles based on UWB/DGNSS
摘要
Abstract
Currently,highway vehicle collision accident rate remains high,but the related research mainly focuses on single-vehicle collision warning based-on ranging of adjacent vehicles,which is not a good way to avoid the chain collision.The main technical challenge of chain collision warning is precise positioning of vehicles.This challenge arises from special restrictions on highway such as lack of power supply,high speed of vehicles,non-line-of-sight of nonadjacent vehicles,low-cost requirement of massive equipment installation and maintenance,etc.In order to address these challenges,a hybrid positioning approach is proposed.The scheme is that,both the relative positioning based on UWB passive RFID and the absolute positioning based on the self-differential satellite signal work collaboratively,and then the precise positioning of the vehicle on highway can be achieved.The research results can be used for vehicle chain collision warning,Internet of things and other areas of high-precision location-based services.关键词
