Abstract: Systems are provided for assisting in towing a trailer by a lead vehicle. A wheeled tow assist unit couples between the lead vehicle and the trailer. A drive unit onboard the tow assist unit drives the wheels in response to a force between the trailer and the tow assist unit. The tow assist unit bears at least a portion of the force required to tow the trailer.

Abstract: A system for trailer coupler localization for guidance during a hitching maneuver for a vehicle includes a trailer device including a trailer coupler and a graphic providing structure affixed to the trailer coupler. The structure includes at least one predefined graphic image. The system further includes a rear facing camera device attached to the vehicle and providing a captured image of the predefined graphic image. The system further includes a computerized controller, including programming to receive and analyze the captured image of the predefined graphic image to determine a relative position of the graphic providing structure to the camera device. The controller further includes programming to utilize the analysis to determine a relative position of the trailer coupler to a trailer hitch ball of the vehicle and to provide an output to control the hitching maneuver based upon the relative position.

Abstract: A method for dampening trailer sway, includes: receiving, by a controller of a vehicle system that is coupled to a trailer, a vehicle speed signal of the vehicle system, wherein the vehicle speed signal is indicative of a vehicle speed of the vehicle system; determining a friction force to be applied to the trailer by an actuator using the vehicle speed of the vehicle system and a graph that establishes a relationship between the friction force to be applied to the trailer and the vehicle speed; and adjusting, by the controller, the graph that establishes the relationship between the friction force and the vehicle speed using the decay rate of the plurality of oscillation amplitudes to create an updated graph.

Abstract: An imaging connection device is provided for use with a vehicle and a trailer. The vehicle includes a hitch assembly, a wired vehicle interface, and a vehicle communications unit, and the trailer includes a tow assembly and a wire harness. The imaging connection device includes a housing defining a first connector configured to mate with the wired vehicle interface and a second connector configured to mate with the wire harness; a connector interface at least partially arranged within the housing and extending between the first connector and the second connector; a camera unit at least partially arranged within the housing and configured to capture image data representing a side view of the hitch assembly; and a wireless communications unit at least partially arranged within the housing and configured to transmit the image data captured by the camera unit to the vehicle communications unit for display on a display device.

Abstract: A towing configuration of a vehicle coupled to a trailer may be evaluated by rolling a tire of the coupled vehicle and trailer over a compressible region of a pressure vessel filled with a hydraulic fluid. A peak pressure of the hydraulic fluid as the tire rolls over the compressible region of the pressure vessel may be determined. The tire load may be determined based upon the peak pressure. Based at least in part on the tire load, a determination may be made whether the towing configuration satisfies a predetermined set of criteria.

Abstract: A power generation platform for delivering power to an external load includes an electrical system mounted to an autonomously-controlled chassis. The chassis has a powertrain that is responsive to control signals from a controller. The electrical system includes a fuel cell or other clean power supply for propelling the chassis, a direct current (DC) charging unit, a turbojet, a battery pack, and one or more electric machines. The DC charging unit and the battery pack are selectively connectable to the external load to deliver power to the external load, e.g., a propulsion battery pack of a vehicle or other system. The turbojet has a compressor, combustion chamber, and turbine, and injects low-emissions fuel into and combusts the fuel in the combustion chamber. The electric machine(s) are rotatably coupled to the compressor and/or the turbine to generate and transmit electricity to the battery pack.
