Curve warning system
First Claim
1. A system for warning a driver of a vehicle approaching a curve at an excess speed, the system comprising:
- a vehicle positioning module which determines the vehicle'"'"'s position in a global positioning system;
a map matching module which determines the vehicle'"'"'s position on a map based on the position in the global positioning system;
a look ahead module which looks ahead on the map for a curve, determines a candidate list of probable driving paths through the curve, and from this candidate list determines the most likely path of the vehicle around the curve; and
a warning module which assesses the threat the upcoming curve poses to the vehicle.

Abstract
The present invention provides a system and method for warning a driver of upcoming curves in a road including. In general, a vehicle positioning module determines the vehicle'"'"'s position in a global positioning system and a map matching module determines the vehicle'"'"'s position on a map based on the position in the global positioning system. A look ahead module looks ahead on the map for a curve, determines a candidate list of probable driving paths through the curve, and from this candidate list determines the most likely path of the vehicle around the curve. A warning module then assesses the threat the upcoming curve poses to the vehicle.
