Systems and methods are provided for managing transitions between operational modes of a vehicle. The system includes a controller configured to, by a processor: automatically transition between vehicular operational modes without initiation by the driver including a hands-off autonomous driving mode in which the processor controls lateral steering of the vehicle, a hands-on driving assistance mode in which the processor controls the lateral steering of the vehicle while the driver is holding the steering wheel, and a no control mode in which the driver controls the lateral steering of the vehicle. The transition between the operational modes is based on sensed data. The hands-off autonomous driving mode is prioritized over the hands-on driving assistance mode which is prioritized over the no control mode. The controller is further configured to display on a human-machine-interface a notification indicating that at least one of the operational modes is active or not available.

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.

A system for closest in path vehicle following using surrounding vehicles motion flow is provided and includes a sensor device of a host vehicle generating data related to vehicles upon a drivable surface. The system further includes a navigation controller including a computerized processor operable to monitor the data from the sensor device, define a portion of the plurality of vehicles as a swarm of vehicles, identify one of the plurality of vehicles as a closest in path vehicle to be followed, evaluate the data to determine whether the closest in path vehicle to be followed is exhibiting good behavior in relation to the swarm of vehicles, and, when the closest in path vehicle to be followed is exhibiting the good behavior, generate a breadcrumbing navigation path based upon the data. The system further includes a vehicle controller controlling the host vehicle based upon the breadcrumbing navigation path.
