Process and device for selecting traffic information
First Claim
1. A process for selecting traffic information received by or to be sent from a vehicle, whereby the selection is carried out in the vehicle in dependence on a type of road on which the vehicle is travelling at a given moment, comprising the steps of:
- carrying out at the vehicle a segment-by-segment determination of a geometric route of the vehicle, whereby information on a particular segment of the geometric route includes at least relative positions of starting and ending points of the segment;
comparing the segment of the route to characteristic geometric parameters of road types; and
, from this comparison, determining the road type currently being travelled and using the road type as a selection criterion.

Abstract
A process for selecting traffic information received by or to be sent from a vehicle, whereby the selection is carried out in the vehicle in dependence on a type of road on which the vehicle is travelling at a given moment. The process including carrying out at the vehicle a segment-by-segment determination of a geometric route of the vehicle, whereby information on a particular segment of the geometric route includes at least relative positions of a starting and ending points of the segment, comparing the segment of the route to characteristic geometric parameters of road types, and, from this comparison, determining the road type currently being travelled and using the road type as a selection criterion.

9. A device in a vehicle for selecting traffic information, comprising:
- a computing processor;
a working memory configured to hold a computing program and collected data;
a memory for permanent preestablished values, the preestablished values including characteristic geometric parameters that are characteristic of particular road types;
a location-finding device;
communications means for receiving and transmitting information; and
a data bus arranged to connect together the computing processor, the working memory, the memory and the location-finding device, the computing program being based on a comparison of collected geometric data of a segment of a route supplied by the location-finding device to the characteristic geometric parameters from the memory, the computing processor being configured to act upon the communications means so that one of a transmission of traffic information and the storing and display of received traffic information is selectively carried out depending on a result of a completed road-type recognition.
