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:
- evaluating, by a computer processor prior to the vehicle'"'"'s approach to a location ahead thereof, multiple data items representing different road features associated with the location in a database coupled therewith to determine whether, when combined, the road network features represented by the multiple data items describe a condition of interest, the database comprising previously collected data representative of features of a road network in a geographic area; and
upon the determination that the road network features represented by the multiple data items which, when combined, describe the condition of interest, providing, by the computer processor, for maneuvering of the vehicle.

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.

11. A computer implemented method for providing precautionary actions in a vehicle comprising:
-
evaluating, by a computer processor, multiple data items associated with a location and already collected and present in a database that contains data items that represents features of a road network in a geographic area; determining, by the computer processor, whether, when combined, the features represented by the multiple data items describe a condition of interest; and upon determining that the features represented by the multiple data items, when combined, describe a condition of interest, providing, by the computer processor, for maneuvering the vehicle when approaching the location. - View Dependent Claims (12, 13, 14)

15. 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 maneuvering the vehicle to modify the operation thereof when the positioning system determines that the current location of the vehicle is approaching a location of features, represented by a subset of multiple data items, determined in combination to describe a condition of interest based on an evaluation of the subset of 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 (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
