Improved vehicle lane detection

Disclosed is a system for improved lane detection using infrared camera to detect friction induced temperature differences in the road surface. Commercially available lane detection works by using an infrared image of the road surface, and relies on different heat absorption between the road surface and the road markings. An obvious problem with this approach is where road markings are missing.

    In situations where road markings cannot be used to identify lanes, detection can be improved by relying on other temperature differences. The friction between tires and the road surface will increase the temperature of the road surface slightly, and in colder climates and/or at night time this slight temperature difference can be detected using infrared camera and thus be used to improve the lane detection.

    This idea uses an infrared camera to capture images of the area in front of the vehicle. Software is used to analyze the images in order to identify the tracks used by previous vehicles travelling the same route.

    The temperature difference will be most noticeable where multiple cars have driven in the same tracks, and can be used to add certainty to the lane detection. This idea is not meant as a stand-alone lane detection mechanism, but rather as an improvement that will add certainty to lane detection.
