Lane Keeping

[Fordstanger]

Curious if anyone knows the science with the physical properties the roads have to have in order for the lane keeping system to work.

Is it something imbedded in the road, paint, etc?

The images from the camera in the windshield are analyzed to determine lane markings (the white and yellow road stripes). The system is calibrated to keep the vehicle in between the yellow and white lines. If the lines are to faded (or missing) the system no longer works.

The display will show colored (green/yellow/red) lines on either side of the truck icon if it can figure out the pavement markings, grey if not. You'll notice it change to grey for example if you're on a rural road with no edge of road paint, if you're next to the end of the merge lane so the line is way off to the side, if the lines are badly faded, etc.

Does the lane keeping assist actually steer the vehicle if it starts going off track, or does it just warn the driver?

Depends, here's the section in V3 of the Owner's Manual.
