Data mining in a digital map database to identify blind intersections along roads and enabling precautionary actions in a vehicle
First Claim
1. A computer implemented method for providing precautionary actions in a vehicle, the method comprising:
- determining, by a computer processor, existence of a hazardous condition from data already collected and present in a database that contains data that represents features of a road network in a geographic area, wherein the step of determining comprises;
evaluating, by the computer processor, multiple data items in the database; and
determining, by the computer processor, whether, when combined, the features represented by the multiple data items constitute a hazardous condition; and
upon determining that the features represented by the multiple data items when combined constitute a hazardous condition, providing, by the computer processor, for taking a precautionary action when approaching a location of the features.

Abstract
Disclosed is a feature for a vehicle that enables taking precautionary actions in response to conditions on the road network around or ahead of the vehicle, in particular, a blind intersection along a section of road. A database that represents the road network is used to determine locations where a blind intersection is located along a section of road. Then, precautionary action data is added to the database to indicate a location at which a precautionary action is to be taken about the blind intersection located along the section of road. A precautionary action system installed in a vehicle uses this database, or a database derived therefrom, in combination with a positioning system to determine when the vehicle is at a location that corresponds to the location of a precautionary action. When the vehicle is at such a location, a precautionary action is taken by a vehicle system as the vehicle is approaching a blind intersection.

9. A vehicle system comprising:
-
a positioning system that determines a current location of the vehicle; and a precautionary action application responsive to the positioning system and operative to provide for taking a precautionary action when positioning system determines that the current location of the vehicle is approaching a location of features, represented by multiple data items, determined in combination to constitute a hazardous condition based on an evaluation of the multiple data items stored in a database of previously collected data that represents features of a road network in a geographic area. - View Dependent Claims (10, 11, 12, 13, 14)
