Data Mining in a Digital Map Database to Identify Blind Intersections Along Roads and Enabling Precautionary Actions in a Vehicle

摘要

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.

主权项

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.
