Design And Realization Of Vehicle Navigation System Based On Cloud Service

The car Navigation System has developed for many years. At present the traditional navigation device exists such problems, Map data is not updated in time, The function is too simple, Poor quality of route calculation, Limited by the hardware of device, expensive etc.The new Navigation System based on cloud computing can deeply remission the conflict between ideal function with reality. It can even be installed in Android and IOS system.The dissertation realized the navigation system based on cloud service. In the dissertation we design the frame of the cloud server and client. We realized route calculation, guide, search, map render. These functions offer server for clients. We realized request to server, Interact with the user at the client side. According to the character of server, we optimized all module of server and data read process.A huge amount of test shows that our system can afford all kinds of functions which contained in traditional navigation. The speed of route calculation, the quantity of details in map render and hint rate of search are superior to traditional one.
