Patent ID: 7751973

Claim:
An in-vehicle system for warning a driver of a vehicle moving at an excess speed, the in-vehicle system comprising: a vehicle positioning module which determines the vehicle's position in a global coordinate system; a map matching module which determines the vehicle's position on a map based on the position in the global coordinate system and a map database; a look ahead module which determines a candidate list of probable driving paths through the curve by the vehicle based on the map database, from this candidate list determines a most likely path of the vehicle around the curve, and which applies a curvature calculation to the most likely path of the vehicle; and a warning module which assesses the threat posed to the vehicle based on the most likely path of the vehicle, the curvature calculation, and the excess speed, the warning module calculating curvature points along the most likely path, threat levels for each of the curvature points, and determining a curvature point of interest being that curvature point with the highest threat level, and wherein the warning module initiates a warning level based on the threat level of the curvature point of interest.
