    Abstract: A method of integrally forming a composite rib structure includes positioning a first fiber sheet on a pre-preg mold, the pre-preg mold including a first channel and a second channel separated by a wedge-shaped protrusion, and the fiber sheet including a plurality of fibers oriented along a first common direction. The method further including extending the wedge-shaped protrusion through the first fiber sheet such that a subset of the plurality of fibers are displaced about the protrusion and into each of the respective first channel and second channel; applying a resin within each of respective first channel and second channel to the plurality of fibers; pre-curing the resin to form a pre-preg rib structure within the channels; and removing the pre-preg rib structure from the pre-preg mold.

    Abstract: A method of forming a casting includes providing a preform to a mold cavity. The preform is formed from one of a first metal and a second metal and defines an interface surface. A molten portion of the other of the first metal and the second metal is cast into the mold such that the molten portion proximately contacts the interface surface of the preform. An interface layer at the interface surface, a first portion defined by the mold cavity and the interface layer, and a second portion defined by the interface layer, are formed during casting. The interface layer may define a metallurgical bond between the first portion and the second portion. In the non-limiting example provided herein, the first portion is substantially comprised of aluminum and the second portion is substantially comprised of magnesium. In a non-limiting example, the casting may be configured as a vehicle wheel.

    Abstract: A trailer backing assistance (TBA) application in a vehicle includes a vehicle attached to a trailer by a movable hitch. The TBA utilizes an HMI, sensors on the vehicle, a GPS system, and a remote computing system (RCS). A controller having a processor, memory, and input/output (I/O) communicates with the sensors, HMI, RCS and GPS via a V2I communications network. The memory stores the TBA which is executed by the processor. The TBA determines conditions have been satisfied, obtains and processes optical data from sensors and RCS, presents a vehicle environment view, prompts a vehicle operator for first and second inputs, calculates a current location of the vehicle, generates a planned path to a target location, presents an animation of the vehicle traversing the path, and continuously displays a live view of the trailer and hitch while actively adjusting on-screen instructions to guide the vehicle and trailer along the path.

    Abstract: A system is provided for mitigating a road network congestion. The system includes a plurality of motor vehicles positioned in associated locations in a road network. Each vehicle has one or more sensors generating an input and a Telematics Control Unit (TCU) for generating at least one location signal for a location of the associated motor vehicle and at least one event signal for an event related to the associated motor vehicle, with the location signal and the event signal corresponding to a High Speed Vehicle Telemetry Data (HSVT data) based on the input from the sensors. The system further includes a computer, which communicates with a display device and the TCUs. The computer includes a processor and a computer readable medium including instructions, such that the processor is programmed to identify the congestion and determine that the congestion is a recurring or a non-recurring congestion.

    Abstract: A display assembly for a vehicle includes an electronic display and an adjustment mechanism. The electronic display is configured to be mounted to an instrument panel of the vehicle. The electronic display includes multiple screens and at least one hinge disposed between the screens. The electronic display is configured to be folded at the at least one hinge by pivoting at least one of the screens about the at least one hinge to adjust a viewing angle of an occupant in the vehicle relative to the at least one screen. The adjustment mechanism is configured to maintain the at least one screen in any one of a plurality of positions when the electronic display is folded at the at least one hinge by pivoting the at least one screen about the at least one hinge to adjust the at least one screen to the one position.
