Embodiment Construction

[0017] The method for quickly realizing vehicle self-navigation in the present invention includes:

[0018] 1. The vehicle navigation terminal requests navigation services from the navigation center through the wireless communication module;

[0019] 2. The driver uses the voice communication of the navigation terminal to notify the navigation center of the destination name;

[0020] 3. The navigation center records the current location and destination of the vehicle, and obtains information such as the latitude, longitude and name of the destination based on the map data in the map database of the navigation center;

[0021] 4. The navigation center sends the information data of the destination to the navigation terminal;

[0022] 5. The navigation terminal of the vehicle receives and stores the information data of the destination, ends the navigation service request at the same time, and then starts self-navigation.

[0023] In said step 1, the driver completes the work of...

Abstract

The invention discloses a method for quick self-navigating for vehicles, comprising the following procedures that: a navigating terminal applies to a navigating center for a navigating service through a wireless communication module; then a driver informs the navigating center the destination through voice; the navigating center obtains information data such as the longitude and latitude of the destination, and the name of the destination according to the map data in a map database, and the information is sent to a navigating terminal to begin a self-navigating; by the method of the invention, the data transmitted is greatly reduced and the time and cost for communication is reduced.

Description

technical field [0001] The invention relates to a method for quickly realizing self-navigation by using a vehicle-mounted map navigation device to connect a navigation center and a vehicle navigation terminal through a wireless communication network. technical background [0002] At present, the general method of autonomous navigation to find the destination is to search POI data. Most of them use pinyin to search for the first letter of the feature name to improve the search speed. However, for some specific users, pinyin search cannot Meet their requirements, especially for users who are not very good at pinyin, it is easy to be distracted and very unsafe to search for destinations while driving; at the same time, the electronic map of autonomous navigation cannot be updated in real time, and sometimes the search fails. To the case of new feature names. [0003] There are also prior patent applications, such as 01816922.8, 02128801.1 and 20510085778.8, etc. The specific i...
