1. A method for lane relative position estimation, wherein this method comprises:
- sensing the environment of a vehicle with at least one sensor means;
extracting spatial features from information obtained from the sensor means;
classifying the extracted spatial features, wherein the spatial features capture lateral position information within a lane by including information having a correlation with a particular location on the lane,wherein a lateral location change results in a different spatial feature value, andwherein the classifying generates directly as a result a lane relative position estimation; and
outputting in an output signal the result of the classification which represents the relative lateral positioning of a road location with respect to an overall lane shape.

Abstract
The invention relates to a system and method for lane relative position estimation. The environment of a vehicle is first sensed, and spatial features are then extracted and classified from information obtained from the sensing. The spatial features capture lateral position information within a lane, and an output signal including the result of the classification, which represents the relative lateral positioning of a road location with respect to the overall lane shape, is generated.
