Abstract

A navigation system for motor vehicles includes a receiving unit for receiving traffic messages to which a location information object is in each case assigned. A display unit for displaying a digital road map and a control unit. The control unit is coupled to the receiving unit and the display unit, and is operatively configured such that cutouts of a digital road map to which the traffic messages relate are successively displayed of the display.

Claims

1. A navigation system for a motor vehicle, comprising:

a receiving unit operatively configured to receive traffic messages to which a location information object is in each case assigned, wherein the location information objects each include a location of a corresponding traffic interruption;

a display unit, in the motor vehicle, for displaying a digital road map; and

a control unit operatively coupled to the receiving unit and the display unit;

wherein the control unit controls a successive displaying on to the display unit of cutouts of the digital road map to which the received traffic messages relate based on corresponding successive operating actions received by the control unit from an operator of the motor vehicle thereby causing a browsing through the cutouts of the digital road map to which the received traffic messages relate, wherein each of the cutouts displayed by said browsing corresponds to one of the locations having the traffic interruptions.

2. The navigation system according to claim 1, wherein the successively displayed cutouts of the digital road map are determined by the location information objects assigned to the received traffic messages.

3. The navigation system according to claim 1, wherein the control unit operates to also display detail information objects in each case assigned to the received traffic messages in addition to the successively displayed cutouts.

4. The navigation system according to claim 3, wherein the successively displayed cutouts are displayed in a preview area of the display unit.

5. The navigation system according to claim 3, wherein the detail information objects of several received traffic messages are displayed simultaneously in list form on the display unit.

6. The navigation system according to claim 4, wherein the detail information objects of several received traffic messages are displayed simultaneously in list form on the display unit.

7. The navigation system according to claim 3, wherein the control unit is operatively configured to mark a detail information object upon receipt of an operating action;

and

wherein a cutout of the digital road map corresponding to the marking is displayed on the display unit.

8. The navigation system according to claim 3, wherein the control unit is operatively configured to display only detail information objects and/or cutouts of the digital road map concerning received traffic messages relating to a current route of the vehicle.

9. The navigation system according to claim 8, wherein the cutout of the digital road map is automatically displayed to which a next traffic message relates that is situated on the current route of the vehicle.

10. The navigation system according to claim 1, wherein the successively displayed cutouts of the digital road map to which the received traffic messages relate are displayed in a preview area of the display unit on a first scale;

and

wherein a further cutout of the digital road map on a second scale is displayed on the display unit, the first scale being smaller than the second scale.

11. The navigation system according to claim 10, wherein symbols assigned to the received traffic messages are displayed by superimposing the symbols on the further cutout.

12. A navigation system for a motor vehicle, comprising:

a display unit, in the motor vehicle, having a first display area in which a list of at least one of location-based information objects, sights, points of interests, addresses and selected destinations are displayable;

a second display area of the display unit for displaying a cutout of a digital road map to which the location-based information objects relate, wherein the location-based information objects each include a location of a corresponding traffic interruption; and

a control unit, in the motor vehicle, operatively configured to receive successive operating actions by an operator of the motor vehicle and, in response, cause a corresponding browsing through successive cutouts of the digital road map to which the location-based information objects relate, wherein each of the cutouts displayed by said browsing corresponds to one of the locations having the traffic interruptions.

13. The navigation system according to claim 12, wherein a successive marking of the corresponding location-based information objects is connected with the browsing through the cutouts of the digital road map to which the location-based information objects relate.

14. A method of displaying road map information using a vehicle navigation system in a motor vehicle, the method comprising the acts of:

receiving, by the vehicle navigation system, one or more traffic messages to which, in each case, a location information object is assigned, wherein the location-based information objects each include a location of a corresponding traffic interruption; and

displaying, by the vehicle navigation system, in succession cutouts of a digital road map to which the received traffic messages relate in response to corresponding successive operating actions by an operator thereby cause a browsing through the cutouts of the digital road map to which the received traffic messages relate, wherein each of the cutouts displayed by said browsing corresponds to one of the locations having the traffic interruptions.

15. The method according to claim 14, wherein the displaying act further comprises the act of determining the cutouts of the digital road map to be displayed in succession based upon the location information objects assigned to the received traffic messages.

16. The method according to claim 14, further comprising the act of:

displaying detail information objects in each case assigned to the received traffic messages.

17. The method according to claim 16, wherein the detail information objects of several received traffic messages are simultaneously displayed in a list form.

18. The method according to claim 17, further comprising the acts of:

receiving an operating action causing a marking of a detail information object; and

displaying a cutout of the digital road map corresponding to the marked detail information object.

19. The method according to claim 14, wherein the cutouts of the digital road map displayed in succession and to which the received traffic messages relate are displayed in a preview area on a first scale, and further wherein a further cutout of the digital road map on a second scale is displayed, the first scale being smaller than the second scale.
