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 curve along a downhill road segment. A database that represents the road network is used to determine locations where a curve is located along a downhill road segment. Then, precautionary action data is added to the database to indicate such a location. 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 such a location, at which a precautionary action is taken by a vehicle system.
