Abstract: Systems, methods, and apparatus are provided for providing multi-trailer reverse assistance. In a multi-trailer reverse assistance system in an articulated transport system comprising a lead vehicle, an intermediate trailer, and a final trailer, the reverse assist system includes a controller. The controller is configured to: receive a view of an environment behind the final trailer; cause the view to be displayed in a display screen of a user interface device; receive, via a secondary steering device of the user interface device, a user intended direction of travel of the articulated transport system in reverse to direct the final trailer in a desired direction; continuously calculate controllable steering angles for directing the articulated transport system to direct the final trailer in the desired direction; and control the articulated transport system to direct the final trailer in the desired direction using the calculated controllable steering angles.

Abstract: In exemplary embodiments, methods and systems are provided for controlling braking of a trailer that is coupled to a vehicle. In an exemplary embodiment, a system is provided that includes: one or more sensors configured to obtain sensor data for a vehicle coupled to a trailer, the sensor data including: a measure of engagement of a brake pedal of the vehicle; and a deceleration of the vehicle; and a processor that is coupled to the one or more sensors and that is configured to at least facilitate dynamically controlling braking of the trailer, via instructions provided by the processor to a braking system of the trailer, based on both the measure of engagement of the brake pedal and the deceleration of the vehicle.

Abstract: Methods, vehicle systems, and vehicles are provided that are capable of managing communication between a vehicle and a portable energy source (PES) coupled to the vehicle. The vehicle systems include a vehicle battery configured to provide electrical power to a propulsion system of the vehicle and a vehicle controller that is configured to establish two-way data communication between the vehicle controller and a PES controller of the PES, determine an energy transfer mode for transferring electrical power between the vehicle battery and a PES battery of the PES, initiate electrical power transfer between the vehicle battery and the PES battery in accordance with the energy transfer mode while the vehicle is being propelled by the propulsion system, receive a status of the PES battery from the PES controller, and adjust the electrical power transfer between the vehicle battery and the PES battery based on the status.

Abstract: Methods and systems to assist maneuvering of a trailer being towed by a vehicle. The trailer includes a left wheel, a right wheel, an axle, a left brake device coupled to the left wheel, and a right brake device coupled to the right wheel. The methods and systems receive a driver command for a target path for the trailer, determine a left braking torque for the left wheel and a right braking torque for the right wheel based on the target path so as to provide for differential braking, and apply, via the left brake device and the right brake device, the left braking torque and the right braking torque to assist maneuvering of the trailer along the target path.
