Gentex Announces Smartbeam DFL Technology For BMW Series
Gentex Corporation has announced that it is supplying its new vision-based, glare-free, high-beam system for the 2012 BMW 3 Series, available throughout Europe.
Known as SmartBeam DFL (Dynamic Forward Lighting), the system consists of a custom CMOS (complementary metal oxide semiconductor) image sensor combined with algorithmic decision-making to offer constant on glare-free high beams. Specifically, the system detects the presence of other headlamps and taillamps and generates dynamic block-out zones around vehicles that it is either following or moving toward. Special headlamps equipped with shutters block portions of the high beams to prevent blinding surrounding traffic while continuously optimising the forward lighting.

SmartBeam DFL allows maximum use of the high beams in order to improve forward visibility and enhance the driver's ability to detect potential road hazards, said Mark Newton senior vice president of Gentex. The vehicle's high beams are in a 'constant on' position, resulting in significantly better forward vision during night-time driving.

Gentex invented the lighting-assist product category in 2001 when it announced its original SmartBeam product, which marked the first time a camera system was used to maximise forward lighting by automatically switching between high and low beams according to surrounding traffic and lighting conditions.

SmartBeam DFL is built off our original and highly successful SmartBeam system, continued Newton. Using a low-cost, custom image sensor design precisely for light detection, we can provide premium high-beam functionality at a reasonable price point, making it perfect for widespread adoption on high-volume vehicles like the BMW 3 Series.

Consumer demand has made SmartBeam one of Gentex's most popular features. The company has shipped nearly 3 million units since 2004. Last year alone the company saw shipments reach the 1 million mark, and Gentex currently expects SmartBeam unit shipments to increase by approximately 40-45 per cent in calendar year 2012.

Approximately 90 per cent of the information required to drive a vehicle is obtained visually, said Newton. Drivers inherently appreciate simple, relatively inexpensive features that enhance visibility and allow them to focus on the driving task. Automakers appreciate SmartBeam because it has a proven track record and because it's relatively easy to integrate into the vehicle.

SmartBeam is integrated into a Gentex automatic-dimming rearview mirror, and the CMOS camera and related electronics are incorporated into the mirror mount. While the mirror mount is attached to the windscreen, the camera floats off the glass, eliminating the angle of the windscreen as a variable, and the mirror assembly functions across vehicle platforms. This design also provides a multitude of upscale styling opportunities that are not available with other systems that require a separate box mounted directly to the windscreen.

Having the SmartBeam system integrated into the rearview mirror is a more elegant styling solution, said Newton. And, because the camera is 'off glass', it minimises potential warranty issues stemming from windscreen replacement and improperly re-installed or misaimed cameras.

Gentex auto-dimming rearview mirrors automatically sense glare from the headlamps of rearward approaching vehicles, and dim in proportion to the amount of glare detected, preserving the driver's forward vision.

SmartBeam is available on the BMW 3 Series in a special Light and Sight package that also comes with Xenon headlamps.
