Problems solved by technology
The calculation of the best path needs to determine the starting point and the destination. Therefore, when there is a traffic jam on the navigation route and the user deviates from the originally calculated best path, a new best path needs to be recalculated, and the best path Calculation is quite time-consuming for the computer, generally takes a few seconds, which limits the application services of traditional navigation, and may increase the application cost of traditional navigation
For example, when developing application services for network navigation (such as the so-called "push-to-talk" that is currently more fashionable), the number of users that a server can serve is quite limited, and some application services also require operators, making network navigation application services high cost
At the same time, the calculation of the optimal route is highly dependent on the navigation map data, and the navigation data is affected by the update time of the navigation map and road changes, and often cannot provide users with accurate navigation tips

Embodiment Construction
[0032] figure 1 It is a schematic structural diagram of Embodiment 1 of the navigation terminal of the present invention. In this example, if figure 1 As shown, the navigation terminal includes a location information acquisition module 11 , a navigation control module 14 and a navigation information output module 15 .
[0033] The location information acquisition module 11 acquires the current positioning coordinates of the navigation terminal. The navigation control module 14 is connected with the position information acquisition module 11, and calculates the relative position and the linear distance of the current positioning coordinates of the navigation terminal obtained by the coordinates of the preset destination and the position information acquisition module 11; the navigation information output module 15, connected with the navigation The control module 14 is connected to convert the relative position and linear distance into the first navigation information outpu...

The invention discloses a navigation terminal and a navigation method. The navigation terminal comprises a position information acquisition module for acquiring the current positioning coordinate of the navigation terminal, and further comprises a navigation control module and a navigation information output module, wherein the navigation control module is connected with the position information acquisition module and used for calculating the relative positions and the straight line distance of the coordinate of the preset destination and the current positioning coordinate of the navigation terminal acquired by the position information acquisition module; and the navigation information output module is connected with the navigation control module and used for converting the relative positions and the straight line distance into first navigation information and outputting the first navigation information. In the navigation terminal and the navigation method provided by the invention, the navigation terminal acquires map data from a map management platform, and makes navigation suggestion for a user with the current moving direction of the navigation terminal as the reference direction by judging the relative positions of the destination and the navigation terminal.
Description
[0001] This application claims the priority of the Chinese patent application with the application number 200910091106.6 and the title of the invention "Navigation Terminal and Navigation Method" filed with China Patent Office on August 7, 2009, the entire content of which is incorporated in this application by reference. technical field [0002] The present invention relates to a navigation terminal and a navigation method, and in particular to a navigation terminal and a navigation terminal capable of navigating to a destination according to navigation data around the destination, key areas or key points on the way to the destination without calculating the best route navigation method. Background technique [0003] The existing terminal navigation technology is a navigation technology based on satellite positioning. It combines the satellite positioning system with the mobile terminal, which can not only provide users with positioning information such as longitude and lati...
