Abstract
The invention relates to a system and method for lane relative position estimation, wherein first the environment of a vehicle is sensed with at least one sensor means; then spatial features from information obtained from the sensor means are extracted which are then classified. 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.
