Abstract: A system for monitoring a trailer includes a detection device configured to monitor a connection between a coupler attached to the trailer and a trailer hitch attached to a vehicle and generate data related to the connection, and a processing device configured to receive the data from the detection device, and analyze the data to detect whether a partial detachment condition is present. Based on detecting the partial detachment condition, the processing device is configured to generate a notification to a driver to alert the driver of the partial detachment condition and/or control operation of the vehicle.

Abstract: 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.
