Abstract

A first user device comprises a first communication interface and a second communication interface. The first user device has digital first map information and is configured for outputting a request message for making navigation information available with regard to at least one desired route section, at the first communication interface. The second communication interface is configured for receiving navigation information that is made available in response to the request message, at the second communication interface, and comprises digital second map information for at least a part of the at least one desired route section. The digital second map information comprises data for display of the at least one part of the at least one desired route section. The first user device is configured for determining digitally updated map information as a function of the digital second map information of the navigation information and of the digital first map information, and for selecting an optical output device for display of the digital updated map information.

Claims

1. A user device comprises:

a memory having digital first map information;

a first communication interface configured for outputting a request message for making navigation information available with regard to at least one desired route section;

a second communication interface configured for receiving navigation information that is made available in response to the request message, wherein the navigation information comprises digital second map information for at least a part of the at least one desired route section, wherein the digital second map information comprises data for display of the at least one part of the at least one desired route section; and

wherein the user device is configured to determine digitally updated map information as a function of the digital second map information of the navigation information and of the digital first map information, and to select an optical output device for display of the digital updated map information.

2. The user device according to claim 1, wherein the user device is further configured to determine the digital updated map information such that the second digital map information of the navigation information is displayed on the optical output device superimposed on the first digital map information.

3. The user device according to claim 1, wherein the digital second map information comprises data for display of planned travel routes and/or of driving maneuvers along the at least one desired route section and/or of a current position of the user device relative to the at least one desired route section and/or of traffic comments.

4. The user device according to claim 1, wherein the navigation information comprises map detail information and one or more graphic elements, and wherein the user device is further configured to embed the one or more graphic elements into the digital updated map information for display of map detail predetermined by the map detail information, and to select the optical output device for display of the predetermined map detail in response to the map detail information.

17. The system according to claim 4, wherein the second user device is configured to determine the map detail information and the assigned graphic elements of the navigation information as a function of the central navigation information and/or of the operating information.

5. A system comprising:

a first user device having a first communication interface configured for outputting a request message for making navigation information available with regard to at least one desired route section;

a central computer device having a communication interface configured to receive the request message from the first communication interface of the first user device, wherein the central computer device is configured to make available central navigation information at the communication interface for transmission to the second user device in response to the received request message, wherein the central navigation information comprises the digital second map information for at least one part of the at least one desired route section; and

the second user device comprises a third communication interface and a fourth communication interface, wherein the third communication interface is configured to make available the received central navigation information, and wherein the second user device is configured to make available the navigation information comprising the digital second map information at the fourth communication interface for transmission to the first user device for the at least one part of the at least one desired route section.

7. The system according to claim 5, wherein the fourth communication interface of the second user device is configured to receive received operating information that is made available by the first user device at the second communication interface.

9. The system according to claim 7, wherein the second user device is configured to determine the digital second information as a function of the operating information.

11. The system according to claim 9, wherein the operating information comprises recorded geographic coordinates for a current position of the first user device.

6. A system comprising:

a first user device having a first communication interface configured for outputting a request message for making navigation information available with regard to at least one desired route section;

a central computer device having a communication interface configured to receive the request message from the first communication interface of the first user device, wherein the central computer device is configured to make available central navigation information at the communication interface for transmission to the second user device in response to the received request message, wherein the central navigation information comprises basic map information for at least one part of the at least one desired route section; and

the second user device comprises a third communication interface and a fourth communication interface, wherein the third communication interface is configured to make available the received central navigation information, and wherein the second user device is configured to determine the digital second map information of the navigation information as a function of the basic map information, and for making the navigation information available at the fourth communication interface for transmission to the first user device.

8. The system according to claim 6, wherein the fourth communication interface of the second user device is configured to receive received operating information that is made available by the first user device at the second communication interface.

10. The system according to claim 8, wherein the second user device is configured to determine the digital second information as a function of the operating information.

12. The system according to claim 10, wherein the operating information comprises recorded geographic coordinates for a current position of the first user device.

13. The system according to claim 6, wherein the second user device is configured to determine a most probable position of the first user device with reference to at least one of the digital basic map information and the digital second map information as a function of the geographic coordinates recorded for a current position of the first user device.

14. The system according claim 12, wherein the second user device is configured to determine a most probable position of the first user device with reference to at least one of the digital basic map information and the digital second map information as a function of the geographic coordinates recorded for a current position of the first user device.

15. The system according to claim 13, wherein the second user device is configured to determine the second digital map information as a function of the determined most probable position of the first user device.

16. The system according to claim 14, wherein the second user device is configured to determine the second digital map information as a function of the determined most probable position of the first user device.
