First Claim
Patent Images

1. A device mountable on a vehicle, comprising:

  • a camera adapted to capture, when mounted on the vehicle, and while the vehicle is in motion, multiple images of a roadway within a field of view of the camera;

    a processor configured to;

    obtain the multiple images from the camera;

    apply image processing to the multiple images to recognize a first roadway lane constraint appearing in at least one of the multiple images;

    determine, based on the multiple images, that one or more defined lane prediction conditions are satisfied;

    in accordance with a determination that one or more defined lane prediction conditions are satisfied, predict a location of a second roadway lane constraint;

    while predicting the location of the second roadway lane constraint, enable automatic control of the vehicle according to the predicted location of the second roadway lane constraint;

    issue a control signal to control a motion of the vehicle according to the predicted location of the second roadway lane constraint;

    determine whether one or more defined lane prediction cancellation conditions are satisfied;

    in accordance with a determination that one or more defined lane prediction cancellation conditions are satisfied, disable automatic control of the vehicle according to the predicted location of the second roadway lane constraint.
