Evaluation of the curvature of an approaching road section from digital map data in which the base map data are used as the basis for an interpolation routine so that curve curvature can be accurately determined

摘要

Method for evaluation of the curvature of a route section being approached by a vehicle in which the route is recorded as a set of base points within a digital map. The curvature of the route section is defined by interpolation between the map points. The curvature can be approximated as a circular section or using splines.
