While there is a tendency for new vehicles to have a focus on ride, handling, performance and other dynamic elements, the model year 2024 Lincoln Nautilus team added another element to how the driver will experience the midsize SUV. Not that the ride, handling, etc. were ignored, but the global design and engineering team wanted to do something different with this two-row SUV. Recognize that this is a vehicle with a sumptuous interior that includes not only first-class seating (24-way adjustable front seats) and materials (Alpine Venetian leather available on the seats; cashmere for the headliner) but also an available high-end Revel Ultima 3D audio system with 28 speakers. What's more, there's “Lincoln Digital Scent,” small electronically activated pods containing various aromas (e.g., Mystic Forest, Ozonic Azure, Violet Cashmere). Across the top of the instrument panel there is a 48-inch backlit LCD screen and a 11.1-inch touchscreen in the center stack
In this study, an optimized structure for opening the headlining considering the deployment of the face-to-face roof airbag was studied. It was confirmed that the deployment performance differs depending on the skin of the headlining, and a standardized structure with mass production was proposed. Non-woven fabric and Tricot skin, which are economical and high-end specifications, satisfy the performance of PVC fusion application specifications after cutting 80% of the skin. The structure that satisfies the entire body including the knit specifications is a type that separates the roof airbag area piece, the corresponding soft piece is separated, and the deployment performance is satisfied with safety. Therefore, the structure is proposed as a standardized structure. This structure is expected to be applicable to roof DAB (Driver Airbag), PAB (Passenger Airbag), and Sunroof Airbag, which will be necessary technologies to secure indoor space. Regardless of which area the airbag will be
Regular readers of Supplier Eye will note that this author tries to outline the positives and the negatives of supplier strategies. It's a moving target. A recent deluge of negative headlines with respect to EVs has OEMs, suppliers and other participants re-evaluating their strategies. Slower consumer acceptance and stalled sales of some EVs - in combination with the recent eye-popping labor agreements with the UAW and Unifor unions - underscore that return on capital and labor-cost challenges will be core considerations going forward. At no point was this transition going to be smooth - “lumpy” is a better description. While there are several positives with the ICE-to-EV transition (emissions, efficiency, reduction of carbon-fuel dependence and running costs), there are hurdles that cannot be dismissed. Of late, several of these concerns have become more prominent. One surrounds the ability for government and industry to effectively bridge the higher costs (due to scale economies) of
Passenger cars in the top segment have seen fast growth over the last few decades with an increasing focus on luxury, convenience, safety and the quality of driver experience. The headliner is a decorative and functional trim system covering the underside of the roof panel. It enhances the aesthetics and elegance of the car interiors. In premium vehicles, the headliner system has to suffice interior quietness and integrity apart from the performance and regulatory requirements. The Design Validation Plan requirements cover its contribution to the vehicle interior noise control, occupant safety, and perception of build quality. Contributions can be very significant and primarily be determined by design and material parameters. Also, headliner interactions with an adjacent body in white structure are crucial from performance point of view. Various foam options are available with different functions such as structural, acoustic, and energy-absorption. Part thicknesses vary depending on
There have been several news headlines lately about offenders pointing commercial lasers at helicopters or police personnel, temporarily blinding and distracting them. An increasing number of “laser assault” incidents have led to tougher penalties with fines and jail time in various countries. The lasers typically used in these attacks operate in the visible light spectrum; therefore, these lasers can be blocked by special absorbing optical dyes contained in special laser defense eyewear
Sound absorption materials can be key elements for mass-efficient vehicle noise control. They are utilized at multiple locations in the interior and one of the most important areas is the roof. At this location, the acoustic treatment typically comprises a headliner and an air gap up to the body sheet metal. The acoustic performance requirement for such a vehicle subsystem is normally a sound absorption curve. Based on headliner geometry and construction, the sound absorption curve shape can be adjusted to increase absorption in certain frequency ranges. In this paper an overall acoustic metric is developed to relate design parameters to an absorption curve shape which results in improved in-vehicle performance. This metric is based on sound absorption coefficient and articulation index. Johnson-Champoux-Allard equivalent fluid model and diffuse field equations are used. The results are validated using impedance tube measurements. It is shown the specific airflow resistance of the
Biodegradable headlinings were developed using jute fiber, PLA (polylactic acid) fiber. More specifically, the main felt which consists of jute fibers and PLA fibers was produced by carding process, and then laminating PLA Films or light PLA felts as reinforcement. After lamination, cotton nonwovens were used as skin layers. Evaluation on the biodegradation of headlinings was tested under conditions (KS M 3100-1 and ISO-14855-1) of aerobic biodegradation. The test results of biodegradable headlinings showed a reduction of weight by 48 % and a decrease of mechanical strength by 90% for the biodegradation period. This feature would be attributed to the decomposition of the bio-materials during its biodegradation
With increased awareness about environmental issues, the trend of automobile industry is to use ‘Recycled’ or ‘Biodegradable’ or ‘Energy Recoverable’ material. As a part of this programme, to make the vehicle ‘Green’ in nature, many automobile OEMs have taken the initiative to make use of natural fibre composite in their vehicles. Natural fibre based composite has been successfully proven for less critical as well as for semi-structural applications in an automobile. These typical applications are insulations, headlining, carpets, door pad etc. There is a demanding task for automotive OEMs to meet 85% Recyclability and 95% Recoverability targets by year 2015. To meet the RRR (Reuse, Recycle & Recover) and the ELV (End of Life) regulatory requirements, increased use of natural fibre based composite/ biopolymers is unavoidable. Natural fibre can offer potential advantages such as weight saving and improve overall green rating of the vehicle. Use of renewable resources can also encourage
With high-profile data breaches making headlines regularly, organizations are carefully evaluating their options for protecting mobile data. For years, software full disk encryption, (FDE), has been the preferred means of addressing this threat. But widespread adoption has been hampered by the complexity and cost surrounding these software-based FDE deployments
