A Conception And Practice Of Intelligently Automatically Identifying Road And Updating Based On Car Network Map

In this paper,a new way of thinking and realizing of intelligent road automatic identification and updating of vehicle map is involved.The network of GPS terminal of vehicle or vehicle navigation terminal by car,collected during the running process of the vehicle map has not been planning on track,and there will be no running track and the corresponding planning shows road vehicle latitude and longitude on the map,and related information through the mobile terminal models 3G,4G wireless network upload sent to the car networking cloud map server.Car networking cloud map server receives new path information,to compare the map data storage database information and vehicle upload data in the Internet map server,a plurality of different types of vehicles by obtaining the phase trajectory data of vehicle driving counterparts,intelligent analysis and judgment of the new type of the road,after a systematic analysis of the update added to the car networking map server.Provide car networking vehicle navigation terminal incremental update map data,make the car networking map server is always in the latest map data,find and update timely road and road new property change,ensure the vehicle navigation map road information the fastest and correct use,avoid the road information has not been updated due to navigation errors the navigation error occurred.This method comes from the actual application,the overall effect to achieve the design requirements,to achieve new road or road to change,as long as there is a small number of car networking vehicle after a minimum of 4 hours after the vehicle navigation terminal network can automatically update the latest incremental map data use.
