Embodiment approach A
[0086] Embodiment A: The map data provider 11 can obtain new map data of the geographical area when the object to be navigated enters the new geographical area. Optionally, the map data user 12 can locate the navigated object in real time based on the map data, obtain the real-time location information of the navigated object, and provide the real-time location information of the navigated object to the map data provider 11 . The map data provider 11 can determine whether the navigated object enters a new geographic area according to the real-time positioning information of the navigated object; and when the navigated object enters a new geographic area, request the map application server for a new geographic area correspondence map data. The map application server queries whether the map data of the new geographic area is updated, and if the new map data is updated, sends the new map data corresponding to the new geographic area to the map data provider 11 . The map data pro...
Embodiment approach B
[0087] Embodiment B: The map data provider 11 can request new map data from the map application server each time the in-vehicle device is started. The map application server queries whether the map data is updated, and if the map data is updated, sends the new map data to the map data provider 11 . The map data provider 11 receives the new map data corresponding to the new geographical area provided by the map application server as the above new map data.
[0088] Wherein, in some embodiments, the in-vehicle equipment can be automatically activated during the process of being activated by the navigation object. For example, for autonomous mobile devices such as robots and unmanned vehicles, the on-board equipment can be automatically activated during the startup process of the autonomous mobile device. For another example, for some motor vehicles, the on-board equipment can also be automatically started when the motor vehicle lane starts. In other embodiments, the vehicle-ma...
Embodiment approach C
[0089] Embodiment C: The map application server can push the new map data to the in-vehicle device every time the map data is updated. For the map data provider 11, new map data pushed by the map application server can be obtained. In this embodiment C, when the map application server pushes new map data, the object to be navigated may be in the process of traveling, or may be in a state of stopping.
[0090] The map data provider 11 acquires new map data when the object being navigated is in a state of stopping. The map data user 12 can directly authorize the map data provider 11 to update the map data according to the target data hot update method. The update method of the map data in which the object being navigated is in a stopped state is a cold update method, which has higher security.
[0091] In the actual application process, the map data provider 11 can obtain new map data when the navigated object travels based on the map data. When the map data provider 11 acqui...
