Abstract

A method for operating a navigation device comprising a central processing unit (100) and a memory medium (130) with a digitized map is disclosed. The method comprises the following steps: inputting a route with start and target coordinates that can be selected on the map; receiving traffic jam data via an external source (140); displaying a calculated route and the respective traffic jam data; and editing said traffic jam data. In the case of acceptance of a traffic jam a possible bypass of the corresponding route section is calculated and displayed, and in the case of non-acceptance the calculated route section is maintained.

Claims

1. A method for operating a navigation appliance having a central processor unit and a storage medium which contains a digitized map, comprising the following steps:

entering a route using destination coordinates which can be selected on the map,

receiving traffic jam data via an external source,

displaying a calculated route and the respective traffic jam data,

displaying a route section with a traffic jam graphically,

output of received traffic jam data on an output unit in editable form,

reception of editing commands for the output traffic jam data from an input device,

calculation of a new route or route section taking into account the edited traffic jam data following reception of a calculation command via the input device.

2. The method as claimed in claim 1, wherein an area can be defined which is not used for calculating a new route section.

3. The method as claimed in claim 2, wherein the area is defined graphically by a geometric shape.

4. The method as claimed in claim 1, wherein a route section can be entered manually as a traffic jam area.

5. The method as claimed in claim 1, wherein , when the traffic jam data are being edited, the respective data for a traffic jam can be selected sequentially starting with the traffic jam nearest the starting point.

6. The method as claimed in claim 4, wherein a traffic jam starting point and a traffic jam ending point can be entered for the manual entry.

7. A navigation appliance comprising:

a central processor unit,

a storage medium which contains a digitized map,

means for receiving traffic jam data via an external source,

a display unit for displaying a calculated route and the respective traffic jam data,

means for outputting received traffic jam data on the display unit in editable form,

means for editing the traffic jam data, with the means including an input apparatus, and

means for calculating a new route or route section taking into account the edited traffic jam data.

8. The navigation appliance as claimed in claim 7, wherein the input apparatus is a rotation sensor.

9. The navigation appliance as claimed in claim 7, wherein the input apparatus is a pressure sensor.

10. The navigation appliance as claimed in claim 7, wherein the input apparatus is a joystick.

11. The navigation appliance as claimed in claim 7, wherein the input apparatus is a input-sensitive display.

12. The navigation appliance as claimed in claim 7, wherein the input apparatus comprises a gesture interpretation apparatus.

13. The navigation appliance as claimed in claim 7, wherein the input apparatus comprises a voice recognition unit.

14. The navigation appliance as claimed in claim 7, wherein the means for receiving traffic jam data is a mobile telephone.

15. The navigation appliance as claimed in claim 7, wherein the means for receiving traffic jam data is radio capable of receiving traffic jam messages.
