DVN organised a workshop with almost all European car makers and tier-1 lighting suppliers.
Some DVN Gold members have regretted their absence from the intensive event, so I am glad to present today a detailed report of this workshop.

You will discover in this report the lectures presented by Dr Huhn (Audi), Benoist Fleury (Valeo), Dr Schäfer (Philips), Dr Dorissen Hella,Lex  Krzyzanoswki (LSS) and Dr Hamm (AL). You'll also find coverage of the three round table discussions on Xenon, LED and how to sell the advanced headlamps.

At the workshop, divergent opinion was apparent but there was also some consensus amongst the participants. Many questions on timing introduction of LED mass production remain without firm answers.

The four most important challenges are:

LED is the technology of the future…but when?
its introduction timing is not clear:
around five years for one group, more than 10 years for the second group?

Communication is the key point to increase take rate of Xenon then LED.

but how to do a common communication?
What kind of communication: Dealers, Video, Internet?

We have to consider the cost of the LED system with styling constraints.

but price/Timing of LED system is not clear

We have to succeed standardization but how?

on LED chip and module evolution, binning, connection, standardisation, and specifications.

For each subject and each question, you'll find not just coverage, but also comentary.
In spite of the many questions without pat answers, we present a lot of information which will help you to better know the present state of the challenges and benefits of new lighting technologies.

About the sessions
The main lectures which we selected in this report can be classified in 2 categories


- LED headlamps: Lawrence Rice from Osram Sylvania  and Rainer Neumann from Visteon  presented prototypes and concepts. Lawrence demonstrated a hold-in-the-hand sized with one LED module producing  the same performance as a larger halogen headlamp and Rainer showed an LED headlamp with low beam frontal area of 135 mm x 50mm, giving performances not too far off the  Xenon  benchmark.
- Xenon 25W: Jean-Sebastien Straetmans from Philips presented the possibilities of a compact, unitised bulb-ignitor-ballast module with benefit on size, weight, packaging and power saving.
- Front end structure: Ankit Garg from GE India presented a novel energy absorber concept to improve the pedestrian safety, low speed vehicle damageability and repair cost.

 Studies and Surveys

- DUT Darmstadt was very present at Detroit with 2 lectures:
One on the evaluation of headlamp cleaning system performance from lab and field measurements. Stefan Soellner showed the first part of this evaluation with very interesting information on soiling and cleaning; the second part will be presented at VISION congress, this October in France). The second lecture was from Nils Haferkemper which emphasizes the positive influence of LED DRL feature on the conspicuity of motorcycles.

- John Bullough from Rensselaer Polytechnic Institute presented 2 lectures, one about the development of a system that can be mounted along an intersection, curve or parking facility to efficiently gather relevant data about headlamp patterns and aim that might relate to glare or visibility. The result suggests that if vehicle headlamps were better aimed, that the amount of light reaching oncoming driver’s eyes would be more consistent.
John’s second lecture showed the large influence of ambient illuminance from urban areas on the visibility of relevant targets, and show advantages of different headlamp for different target locations where pedestrians might be encountered.

In driver assistance, despite so many technologies arriving in high beam assistant or adaptive lighting, we had only one lecture from Honda R&D, Haruhiko Nishiguchi about Blind Spot Detection and a novel image processing method for more accurate  perception of speed of adjacent vehicles seen in the side-view camera image.
All these lectures are detailed with a lot of explanations, snapshots and figures.

For the first time in this report, at the end of each lecture, we feature an exclusive Q&A with the presenter about some points of his lecture or about analysis of his vision of the future.

Exhibition and awards

Few systems detected on presented close the report with awards of companies and award for experts.

Geneva Motor Show 2010 PDF Print E-mail

2010’s Geneva auto show was centred around one strong priority: the reduction of energy consumption. Alternative powertrain technologies dominated the fair.
Automakers focused their communication on electric vehicles and energy consumption reduction rather than on the safety benefit to be derived from lighting and DA technologies. In this report, Driving Vision News presents all the new cars exhibited in Geneva and their lighting equipment in relation with styling, safety and energy consumption reduction.

North Americans, producers and consumers alike, tend not to have much interest in lighting or driver assistance. In contrast to motor shows in Europe and Asia, there was almost no substantial promotion of driver assistance or lighting technology, nor of energy-saving technology.

Largely the show was populated with Japanese automakers. Nevertheless, there were two points of focal interest for us:
1) Large number of new Japanese cars, production and concepts
2) Presence of the primary Japanese lighting suppliers and most of worldwide driver assistance providers.

With so many new Japanese models, we glean a better sense of the forthcoming trends in the Japanese domestic market as well as the direction of Japanese cars and suppliers in markets worldwide. We see strong priority on the reduction of energy consumption, which means for lighting suppliers wattage reduction, weight reduction and packaging reduction. The link between automakers’ environmental goals and lighting technology and styling is particularly emphasized.

IAA frankfurtSome 85 new vehicles made their world debuts here — though in truth, some were introduced off-site or had been displayed previously at other events — and the German automakers used their home field to maximum advantage.

About the sessions

• The main lighting focus was on LED energy consumption benefits, on Halogen/Xenon/LED studies and survey results.
One interesting paper was presented on a new BiHalogen projector module with details on its development, light source, adaptability, and performance characteristics.
Several good papers analysing the safety aspects of Halogen vs Xenon vs LED were presented with some surprising results on glare.

Automakers and design houses used the show to display more than 15 concept cars and 20 new production cars for markets round the world. These sorts of numbers are normally seen during boom times.
Of course, many of these product plans were started when times were good. The glitz of past years likely will be muted in the near future due to budget cuts. Still, the roster of vehicles is impressive, with emphasis on both performance and economy.

At a time when automakers are pulling out of auto shows, putting the very survival of the events at risk, the Geneva salon is perhaps one last display of optimism from an industry looking for any hint of good news.
