GPS navigation method and system

Abstract

The invention relates to a GPS navigation method and a system and comprises that a navigator sends a navigation requirement to a calling center, wherein, the navigation requirement comprises the information about the present position of the navigator, the information about the position of the destination and the ID information of the navigator; the calling center formulates a routes plan based onthe navigation requirement and a dynamic traffic information; the calling center delivers the routes plan and an authorization information for activating a map file in the navigator to the navigator;the navigator receives the routes plan and the authorization information and activates the map file to display the planed routes; in the running process of the vehicle, the calling center formulates a novel routes plan according to the latest position information and the dynamic traffic information sent out by the navigator and delivers the novel routes plan to the navigator. In addition, the navigator sends out the edition information of the map file corresponding to the road sections around the present position stored in the navigator while sending out the present position information; the calling center compares the received edition information with the edition of the map used by the calling center and then determines the data increment of the map and delivers the data increment to thenavigator.

Description

technical field [0001] The invention relates to GPS navigation technology, more specifically, to a pay-per-view dynamic navigation method and system. Background technique [0002] The navigation electronic map has two characteristics: it is an electronic data product and it has a navigation function. The biggest difference between ordinary electronic map and navigation electronic map is that the former does not have navigation function. In order to realize navigation, only map data is not enough. There must be a map engine for path planning, selection and other functions. Map data and map engine (software) are inseparable. [0003] GPS navigator is a car driving assistance device that can help users accurately locate the current location, calculate the itinerary according to the established destination, and guide the user to the destination through map display and voice prompts. It includes two important components: First, the Global Positioning System (Global Positioning...

AI Technical Summary

Problems solved by technology

[0006] Furthermore, in the current GPS navigation products, users often need to purchase navigation software at one time, which requires high capital investment, and most of the data is not used, especially in the initial stage of evaluating navigation electronic maps, users do not have suitable evaluation means and Chance

Thus setting a threshold for the popularization and use of navigation software
