ROAD PROFILE PREDICTION

摘要

An apparatus for road profile prediction comprises digitisation and storage means operable to digitise and store video image data relating to the road ahead of the vehicle and processor means operable to process the video image data to identify lane markings in the road, characterised in that the processor means includes estimator means operable to simultaneously analyse pairs of lines considered to constitute lane markings by a single recursive estimation procedure by finding the best fit to an expression involving left and right offsets, heading angle, lane curvature and horizon offset. A system embodying the invention has the purpose of overriding normal vehicle cruise control when another vehicle is detected in front of the vehicle.
