First Claim
1. A method for making a component for a vehicle system that provides a precautionary action in a vehicle when the vehicle approaches a potentially hazardous location along a road of a road network, wherein the component comprises an augmented version of a database that represents the road network in a geographic region, the method comprising:
- determining a type of hazardous condition to identify and, based thereon, identify a first condition and a second condition, the satisfaction thereof at a same location is indicative of the hazardous condition;
evaluating, prior to operation of the vehicle system to provide a precautionary action when the vehicle approaches a potentially hazardous location along a road of a road network, data contained in a first version of the database to identify locations along roads of the road network where the determined hazardous condition might exist, wherein the hazardous condition comprises a combination of the first condition and the second condition which are satisfied together at a same location along a road of the road network, wherein the step of evaluating further comprises;
evaluating a first type of data that represents geographic features of an identified location along the road of the road network to determine if the first condition is satisfied thereby, andupon determining that the first type of data that represent geographic features satisfies the first condition, evaluating a second type of data that represents geographic features which are geographically located around the identified location along the road of the road network at which the first condition is satisfied to determine if the second condition is satisfied at or around the identified location at which the first condition was satisfied; and
upon determining satisfaction of the second condition at or around the identified location at which the first condition was satisfied, adding precautionary action data to the first version of the database in association with the identified location to form the augmented version of database to indicate that a precautionary action is to be taken by the vehicle system when the vehicle system determines that the vehicle is approaching the identified location along the road of the road network.

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. A database that represents the road network is used to determine locations where a potentially hazardous condition exists. Then, precautionary action data is added to the database to indicate a location at which a precautionary action is to be taken relating to the hazardous condition. 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 the location where the potentially hazardous condition exists.
