Method for updating the data of a navigation system
In a method for updating the data of a data storage device of a navigation system, updated data are transmitted by local data transmission stations and stored in the data storage device. To improve the usage opportunities of the navigation system, the updated data are transferred to a service provider.
1. A method for updating data of a data storage device of a navigation system, comprising:
receiving data from, and updated by, local data transmission stations, wherein the data comprises navigation system data detailing conditions of a road network;
storing the data, updated by the local data transmission stations, in the data storage device, wherein the data storage device is located in the navigation system, and wherein the navigation system is located onboard a vehicle;
transferring the data stored in the data storage device to a service provider; and
transmitting the data received by the service provider to a second navigation system.
2. The method according to claim 1 , wherein the transferring the data comprises wirelessly transmitting the data to the service provider.
3. The method according to claim 1 , wherein the receiving the data takes place actively or passively.
4. The method according to claim 1 , further comprising generating a message upon receipt of the data by the navigation system.
5. The method according to claim 1 , wherein the data storage device is portable and rewritable.
6. The method according to claim 1 , wherein the transmitting of the data comprises transmitting the data to the service provider over the internet.
7. A navigation system, comprising:
a receiving device configured to receive data from, and updated by a local data transmission station, wherein the data comprises navigation system data detailing conditions of a road network;
a data storage device configured to store the data received by the receiving device, wherein the data storage device is located in the navigation system, and wherein the navigation system is located onboard a vehicle; and
a transmitting device configured to:
transmit a request to receive the data updated by the local data transmission station; and
transmit the data stored by the data storage device a service provider.
8. The navigation system according to claim 7 , wherein the receiving the data takes place passively.
9. The navigation system according to claim 7 , further comprising a message generator configured to generate a message upon receipt of the data by the navigation system.
10. The navigation system according to claim 9 , wherein the message is a visual message.
11. The navigation system according to claim 7 , wherein the transmitting device is a wireless transmitting device.
12. The navigation system according to claim 7 , wherein the data storage device is portable.
13. The navigation system according to claim 7 , wherein the data storage device is rewritable.
14. The navigation system according to claim 7 , wherein the data storage device is portable.
15. The navigation system according to claim 7 , wherein the transmitting device is configured to transmit the data to the service provider over the internet.
