Methods and systems are provided for a vehicle towing a trailer within a lane of a roadway that include: reconstructing, via a processor onboard the vehicle, lane markings for the trailer using lane markers as sensed via camera data; transforming the reconstructed lane markings, using additional sensor data, to a perspective of the trailer; localizing the trailer within the transformed lane markers using historical camera lane marking information, articulated vehicle dynamics, hitch angle, and trailer dimensions, without needing to add additional trailer lane sensing cameras to the trailer; calculating a time to lane crossing (T-TTLC) value for the trailer and vehicle; generating candidate blended paths of the trailer and the vehicle with a centerline of the lane of the roadway; and controlling operation of the vehicle, the trailer, or both, via instructions provided by the processor to keep the vehicle, the trailer, or both within a lane of travel.
