Problems solved by technology

However, due to the rapid development of road construction, especially the increasing renewal of urban roads, it has become impractical to frequently take vehicle-mounted terminals to manufacturers or agency points for map upgrades and cannot meet people's needs.
Therefore it is necessary to provide a new method for upgrading car navigator maps, which aims to overcome the disadvantage that existing car navigator maps can only be updated offline

Abstract

The invention specifically relates to a method for a vehicle-mounted navigator to update a map on line, and the method comprises the following steps that (1) the vehicle-mounted navigator is connected to a service platform via a mobile communication network by using mobile communication equipment as a router; (2) the service platform acquires the latest map version information according to the hardware information and software specifications of the vehicle-mounted navigator, and the vehicle-mounted navigator receives the map version information and compares the same with the current map version information; (3) when the map version information received by the vehicle-mounted navigator is higher than the current map version information, a map with the latest version is downloaded from the service platform for updating; the mobile communication equipment comprises a Wi-Fi (Wireless Fidelity) function and can be set into a routing mode; the vehicle-mounted navigator is integrated with a wireless network module and is responsible for communicating with the mobile communication equipment. According to the method for the vehicle-mounted navigator to update the map on line, the problem that the vehicle-mounted navigator cannot update the map on line is solved via the mature mobile network, and has the advantages of convenience, practicality and economy.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for realizing online map updating of a car navigator. Background technique [0002] Car navigator is a driving auxiliary device that can help users accurately locate the current location, calculate the itinerary according to the predetermined destination, and guide the user to the destination through map display and voice prompts. [0003] With the development of social economy, the scale of the automobile market is getting bigger and bigger, and the number of users who own cars is also increasing. With the maturity of satellite navigation technology, satellite navigation systems such as car navigator GPS and Beidou can quickly locate the current location coordinates of the car, thereby promoting the gradual popularization of car navigators. The principle of GPS technology is that the car navigator sends a request for location information to the satellite through...
