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 making an augmented version of a database that can be used as a component in a vehicle system, the method comprising:
- using, by a computer processor, data contained in a first version of a database to identify at least one geographic feature satisfying a first condition at a first location and determine, if the identified at least one geographic feature satisfies the first condition at the first location, whether at least one geographic feature in a vicinity of the first location satisfies a second condition; and
forming, by the computer processor, the augmented version of the database by adding precautionary action data to the first version of the database in association with each of the identified at least one geographic feature when at least one of geographic features in the vicinity thereof satisfies the second condition, the precautionary action data operative to enable a precautionary action to be taken by the vehicle system.

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.

8. A database stored on a non-transitory computer-readable medium, wherein the database includes data that represents a road network in a geographic region, wherein the database comprises:
-
data records that represent road segments that make up the road network; data records that represent one or more intersections of roads in the road network; data that represent geographic features along one or more roads leading to the one or more intersections; and data that indicates one or more precautionary action locations, wherein each of the one or more precautionary action locations is associated with a geographic feature satisfying a first condition at a first location with at least one geographic feature in the vicinity thereof satisfying a second condition, the precautionary action data operative to enable a precautionary action to be taken by a vehicle system. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A vehicle system comprising:
-
a database that contains data representing a geographic region in which a vehicle is being operated, wherein the data includes data that represents a road network located in the geographic region and precautionary action data associated with a geographic feature satisfying a first condition at a first location with at least one geographic feature in the vicinity thereof satisfying a second condition; a positioning system that determines a current location of the vehicle relative to the data representing a geographic region; and a precautionary action application responsive to the positioning system and the database that provides a precautionary action when the positioning system determines that the current location of the vehicle is approaching a location associated with precautionary action data. - View Dependent Claims (16, 17, 18, 19)

20. A computer implemented method for providing precautionary actions in a vehicle comprising:
-
determining by a computer processor, a current position of the vehicle; accessing by the computer processor, a database that represents a road network to obtain data representations of a part of the road network around of the current position of the vehicle; and upon determining by the computer processor, that the data representations of the part of the road network around the current position of the vehicle include precautionary action data indicative of a geographic feature satisfying a first condition at a location with at least one geographic feature in the vicinity thereof satisfying a second condition, taking a precautionary action as the vehicle is approaching the location. - View Dependent Claims (21, 22, 23)
