Abstract

A method is provided for outputting an item of directional information, which corresponds to an item of location information displayed on a traffic sign, which location information is assigned to a section of the route that follows when viewed from a current section of a route, and in the case of a plurality of items of location information assigned to the following route section, preferably the particular item(s) of location information is/are used as basis for the output of the directional information that exhibit(s) the greatest frequency for the route sections following the following route section, as well as a system for implementing the method.

Claims

1-6. -6. (canceled)

7. A method for outputting to a driver of a vehicle an item of directional information, comprising:

providing, for a selected item of location information among multiple items of location information displayed on a traffic sign along a travel route having multiple route segments, at least one selected item of directional information associated with the selected item of location information as an output, wherein the selected item of location information is assigned to an immediately subsequent route segment of the travel route when viewed from a current route segment of the travel route;

wherein, if multiple items of location information are assigned to the immediately subsequent route segment of the travel route, an item of location information exhibiting the greatest frequency of association with the immediately subsequent route segment and further subsequent route segments of the travel route is determined and used as a basis for selecting the at least one item of directional information as the output.

8. The method as recited in claim 7, wherein the multiple items of location information include the names of places able to be reached via the immediately subsequent route segment.

9. The method as recited in claim 8, wherein the determination of the item of location information used as the basis for selecting the at least one item of directional information as the output is performed each time the vehicle has traveled past a route segment of the travel route.

10. The method as recited in claim 8, wherein the determination of the item of location information used as the basis for selecting the at least one item of directional information as the output is performed each time the vehicle has traveled past a traffic sign bearing an item of location information.

11. The method as recited in claim 10, wherein the determination of the item of location information used as the basis for selecting the at least one item of directional information as the output is performed each time the vehicle has traveled past traffic signs of the same type.

12. A system for outputting an item of directional information to a driver of a vehicle, comprising:

a memory unit storing, for an item of location information displayed on a traffic sign along a travel route having multiple route segments, information representing traffic route segments associated with the item of location information, wherein, for a selected item of location information among multiple items of location information displayed on a traffic sign along the travel route having multiple route segments, at least one selected item of directional information associated with the selected item of location information is provided as an output, wherein the selected item of location information is assigned to an immediately subsequent route segment of the travel route when viewed from a current route segment of the travel route; and

a control unit configured to determine and use, in the case multiple items of location information are assigned to the immediately subsequent route segment of the travel route, an item of location information exhibiting the greatest frequency of association with the immediately subsequent route segment and with further subsequent route segments of the travel route as a basis for selecting the at least one item of directional information as the output.
