4. The navigation system of claim 3, wherein, when the service mode is the navigation route navigation mode, the vehicle terminal uploads the obtained driving related information and its own navigation route information to the server, and when a recommended route having a shorter distance or time than its own navigation route is searched for, uploads the retrieved recommended route to the server.

5. The navigation system of claim 4, wherein, when the recommended route is downloaded from the server, the vehicle terminal provides the navigation service according to the recommended route downloaded from the server.

6. The navigation system of claim 1, wherein the vehicle terminal comprises:

a wireless communication module configured to upload the driving related information and the navigation route information to the server, transmit the driving related information and the navigation route information to the at least one member vehicle, and transmit the driving related information and the navigation route information downloaded from the server or received from the leader vehicle; and

a processing module configured to transmit the obtained driving related information and its own navigation route information to the wireless communication module, or provide the navigation service according to the driving related information and the navigation route information transmitted from the wireless communication module.

7. The navigation system of claim 6, wherein, when the processing module is installed in the vehicle terminal of the leader vehicle, the processing module transmits the driving related information and its navigation route information to the wireless communication module so that the driving related information and its own navigation route information is uploaded to the server, and when a recommended route having a shorter distance or time than its own navigation route is searched for, transmits the recommended route to the wireless communication module so that the recommended route is uploaded to the server.

8. The navigation system of claim 6, wherein, when the wireless communication module is installed in the vehicle terminal of the at least one member vehicle, the wireless communication module transmits the driving related information and the navigation route information downloaded from the server to the processing module when the service mode which is set is a navigation route navigation mode, and transmits the driving related information and the navigation route information received from the leader vehicle to the processing module when the service mode in a real-time cooperative driving mode.

9. A navigation control method, comprising:

setting a cluster driving mode on its own vehicle as one of a leader driving mode and a member driving mode;

uploading driving related information and navigation route information on its own vehicle to a server when the cluster driving mode is the leader driving mode, and transmitting the driving related information and the navigation route information to a vehicle in which the cluster driving mode is the member driving mode; and

providing a navigation service to its own vehicle according to the driving related information and the navigation route information downloaded from the server by requesting the uploaded information to the server or received from a vehicle in which the cluster driving mode is the leader driving mode when the cluster driving mode is the member driving mode,
