Influence of Background Spectral Distribution on Perceptions of Discomfort Glare2020-01-06374/14/2020
The advent of light-emitting diode (LED) technology for automotive lighting allows flexibility of the spectral distribution of forward headlighting systems, while meeting current requirements for “white” illumination. As vehicle headlights have become whiter (with more short-wavelength light output) over the past several decades, their potential impacts on visual discomfort for oncoming and preceding drivers have been hotly debated. It is known that a greater proportion of short-wavelength energy increases discomfort glare, and that increasing the background light level (e.g., through roadway lighting) will decrease perceptions of discomfort. More recently it has been demonstrated that the visual system exhibits enhanced short-wavelength sensitivity for perceptions of scene brightness. As a result, roads illuminated by light sources with higher correlated color temperatures (CCTs) will be judged as appearing to be brighter than those illuminated to the same light level by sources with lower CCTs. The present laboratory study was conducted to identify whether the increased scene brightness of a road illuminated with greater short-wavelength light helps to mitigate discomfort glare more than the same scene illuminated to the same light level, but with less short-wavelength light. The results indicate that the spectral distribution of the background plays little role in the degree to which it lessens discomfort glare. The implications of these results for vehicle and road lighting practices are discussed.

Far and Away: Remote Drivers Monitor Autonomous Vehicles19AVEP11_0411/1/2019
Remote operators are helping autonomous shuttles and other AVs navigate through complex situations. Eliminating the safety “watchdogs” who typically ride in autonomous vehicles (AVs) is a big step for technologists and legislators alike. A shuttle at Texas A&M University is among the first on public streets to replace these drivers with a remote operator who monitors vehicle behavior from an operations center. Teleoperation increasingly is considered as a way to augment automated-vehicle systems when they encounter situations that are difficult to analyze. Startups such as Phantom Auto, Starsky Robotics, Veniam and Designated Driver are establishing operations centers where remote drivers constantly watch for challenges that aren't easily handled by AV algorithms. Larger players such as Valeo, Uber and General Motors also are developing teleoperation strategies.

Design of an Energy-Efficient Critical Angle Lens ReflectorTBMG-347687/1/2019
The critical angle lens reflector has commercial applications that supersede ordinary mirrored reflectors. The physics of the critical angle lens reflector are based on the optics principle of total internal reflection. Total internal reflection is characterized as follows: (1) as shown in Figure 2, the light rays are reflected off of the reflecting surface whereby the angle of reflection – with respect to the perpendicular to the reflecting surface – is equal to the angle of incidence of the ray, and (2) the reflection of the light ray takes place with no loss of energy upon reflection.

Bendable Electronic Paper Displays a Range of ColorsTBMG-343825/1/2019
The combination of conductive polymers on nanostructures was demonstrated as suited to creating electronic displays as thin as paper. The “paper” is similar to the Kindle tablet. It does not light up like a standard display, but rather reflects the external light that illuminates it; therefore, it works very well where there is bright light such as sunlight, in contrast to standard LED displays that work best in darkness. At the same time, it needs only a tenth of the energy that a Kindle tablet uses, which itself uses much less energy than a tablet LED display.
Glare Investigations and Safety Research on Digital Light Technologies2019-01-08494/2/2019
New human-machine interfaces are the direct result of digitalization. So also in lighting, new constellations have to be taken into account when looking to the possibilities of giving additional informations to the driver. Lighting and furthermore information given by light is a clear preference during nighttime driving. The global interest in standardization of light driven messages from autonomous vehicles to other traffic participants has opened new research needs in order to prepare full view on such new human-machine interface. In Europe, GTB (Group de Travail de Bruxelles) has established a working group dedicated to this topic. In order to provide a complete picture of the effects of digital light, the question of additional glare contribution by digital informations, i.e. extra projected light in form of patterns, symbols or areas was addressed in this research study. This article will show the investigations on wet and dry road glare while driving with digital informations. Objective data about the glare investigation and respective driving situation will be presented.

Porsche reveals eighth-generation of fabled 91119AUTP01_151/1/2019
Regularly updating and evolving the Porsche 911's aesthetic signature might seem an impossible task. But more than half a century after its birth, the unveiling of the eighth-generation at the 2018 L.A. Auto Show demonstrated that it is in fact still a totally possible art-with design boss Michael Mauer the chief artist. Designated in-house as the 992 series and slightly larger than the outgoing 991, it is launched in rear-wheel-drive and all-wheel-drive forms-Carrera S and Carrera 4S-and now only in the wide-body width previously used for the Carrera 4 GT3 and GTS, instead of two body widths. Across the nose, the new 911 is 45 mm (1.8 in) wider than the outgoing version, a figure some 911 purists may look at askance, as growth in recent years has already been considerable.

Engineering AVs to ‘play nice’ with humans18AUTP11_0411/1/2018
More than a decade after the DARPA Grand Challenge program demonstrated the technical viability of self-driving vehicles, the industry is now preparing its first commercial deployments of the technology at scale. While Waymo, GM Cruise, Aptiv and others begin to ramp-up automated ride-hailing services for paying passengers, unanswered questions remain. Many of them revolve around the “social” aspects of the technology. Engineering is about taking the principles learned from science and applying them to solving real-world problems. But if the resulting technology requires people to change their behavior for it to work reliably, the engineers are doing it wrong.

A Novel Barricade Warning Light System Using Wireless Communications2018-01-50369/12/2018
Workers in construction and transportation sectors are at increased risk for work-related injuries and fatalities by nearby traffic. Barricade-mounted warning lights meeting current specifications do not always provide consistent and adequate visual guidance to drivers and can contribute to glare and reduced safety. Through an implementation of sensors and wireless communications, a novel, intelligent set of warning lights and a tablet-based interface were developed. The lights modulate between 100% and 10% of maximum intensity rather than between 100% and off in order to improve visual guidance and adjust their overall intensity based on ambient conditions. The lights can be synchronized or operated in sequential flash patterns at any frequency between 1 and 4 Hz, and sequential patterns automatically update based on global positioning satellite (GPS) locations displayed in the control interface. A successful field demonstration of the system verified that its functions were viewed favorably by transportation safety personnel.

2021-12-29.TEST Sine Wave Pulse Width Modulation Study for Improving Vehicle Lighting Control *CSP Meta Testing*2018-01-00014/3/2018
Vehicle lighting has become more demanding with different load requirements, strict Electromagnetic Compatibility (EMC) requirements, accuracy requirements, and power consumption requirements. These requirements are all under the constraint of ever shrinking PCB’s driving up the cost of PCB real estate. Pulse width modulation (PWM) is used to control the interior and exterior lighting in vehicles and meet all these requirements. One or more electronic control units in the body domain of a vehicle contain a number of integrated circuits that drive loads using PWM signals. In addition to driving loads, PWM signals are used for things such as dimming and diagnostic functions. In current technology the PWM signal is usually composed of a trapezoidal wave or rounded wave which control bulbs and light emitting diodes (LED) loads in a vehicle. The trapezoidal or rounded wave may not be the most efficient way to meet requirements in the automotive industry due to their sharp rising edges so different methods have been developed to improve functionality and reduce cost. Using PWM with sine wave control could be an improvement over the current technology. This study looks at two integrated circuits that use each control method, the rounded wave and the sine wave. Both control methods are studied with the same PCB layout and environmental conditions then compared through testing such as radiated emissions testing and thermal testing. The comparison is used to determine which method is more beneficial for use in controlling automotive lighting. Other methods in recent literature are also reviewed along with future outlooks on controlling lighting loads in the automotive industry.

Influence of Oncoming Light Exposure on Safety Outcomes in a Naturalistic Driving Study2018-01-10394/3/2018
Recent naturalistic driving studies provide a useful means for gathering information about the potential role of lighting in driving safety. The Naturalistic Driving Study carried out through the Strategic Highway Research Program 2 (SHRP2) includes real-time driving data for crashes, near-crashes and baseline driving events for more than 3000 drivers across the United States. Among the data collected are oncoming illuminance recordings that can be used to estimate glare exposure for the drivers in the study. Data for crash events occurring at night were compared to those for baseline driving under similar conditions and by drivers of similar ages. The resulting light exposure data indicate that oncoming glare is likely to be only a very small factor associated with nighttime crashes, but that the influence of glare may increase for older drivers.

A Study on the Method to Manage the Weight and Cost of a Vehicle by Adjusting the Parameters of Styling Profile2018-01-10254/3/2018
Since the fuel efficiency of vehicle has become one of the big issues due to environmental pollution problems, many studies have been conducted on various methods such as improving powertrain performance and aerodynamic performance, reducing the weight of the vehicle and so on. There have been many new attempts to reduce weight but mostly about improving material property. In the case of vehicles sharing the same platform, the weight and cost of vehicle are mainly changed by the exterior styling. But, there is no solution to control the exterior styling in terms of the weight and cost of vehicle, yet. The purpose of this study is to find the way to save the weight and cost of vehicle while achieving the various performance and requirements of vehicle (safety, aerodynamics, driver’s visibility and so on) from exterior styling point of view. We focused on the weight difference of the vehicles that shared the platform and were same overall dimensions. We analyzed vehicle’s components that make up the exterior design and classified them by materials. Because each part is different in material and has a different specific gravity, depending on how large area each part occupies in the exterior design, the exterior styling can affect the total weight of vehicle. Then we found correlations between weight, cost and styling and parameters to control these. Also in order to consider the performance and requirements of vehicle, the relationship between styling parameters and those was analyzed. From the results, the method is proposed to control the weight and cost of vehicle by managing the total area of exterior surface and the area ratio of parts in the styling. In the future, this approach will be available for the exterior design optimization.
