Abstract

The invention provides a map updating method and device and a vehicle, and the method comprises the following steps: determining the position of the vehicle after a navigation device in the vehicle isstarted, and determining a first updating region with the position of the vehicle as the center; sending a first updating request to a server, with the first updating request comprising map grid information covered by the first updating area and information of a navigation device; and if the map increment updating data of the first updating area fed back by the server is received, updating the local map data of the first updating area according to the map increment updating data of the first updating area. According to the map updating method, the map data can be locally updated in an incremental mode, the data size is small, the consumed data flow is small, national updating or provincial and municipal updating is avoided, the data updating time is short, updating is conducted only whenthe map data is used, a guarantee is provided for a vehicle-mounted navigation system to use the latest map data, and the user experience is greatly improved.

Description

technical field [0001] The invention relates to the technical field of data updating, in particular to a map updating method, a map updating device and a vehicle with the device. Background technique [0002] With the rapid development of social economy, people's living standards have been greatly improved, and automobiles have become a tool for daily travel. Today's road network in my country is developing rapidly, and road changes are very frequent, resulting in frequent changes in map data, the basis of vehicle navigation. When using a car navigation system that does not have a map data update function, you often encounter situations such as going the wrong way, detours, and road closures due to road construction. [0003] In addition, the data volume of navigation electronic maps is very large now. The map capacity in the whole country reaches 15G, and the average province also needs to reach hundreds of megabytes. The current map data update uses the full version of t...
