Gentex Corporation, a producer of camera-based lighting-assist systems and automatic-dimming rearview mirrors, recently declared the availability of its new glare-free, vision-based, high-beam system for the 2012 BMW 3 Series, across Europe. Gentex is based in Zeeland, Michigan.
Gentex integrates decision logic and a custom imager into its auto-dimming rearview mirrors to provide drivers of the new BMW 3-Series with constant-on, glare-free high beams.
The new system is called SmartBeam DFL (Dynamic Forward Lighting). It includes a custom CMOS (complementary metal oxide semiconductor) image sensor integrated with algorithmic decision-making and generates invariable ‘on’ glare-free high beams. The system particularly detects the existence of other taillamps and headlamps. It produces dynamic ‘block-out’ zones around the vehicles. Special headlamps in-built with shutters prevent blinding and constantly optimize forward lighting.
In 2001, following the launch of original SmartBeam product, Gentex invented the lighting-assist product category. The increased demand for SmartBeam demonstrates its high product value and is believed to be one of the company’s most popular features. SmartBeam is combined with the CMOS camera, a Gentex automatic-dimming rearview mirror. The mirror mount, equipped with related electronics is attached to the windscreen. Following the installation, the camera ‘floats’ away from the glass, the angle of the windscreen is eliminated as a variable, and the mirror assembly operates throughout the vehicle platforms. In addition, various upscale styling potentials are also incorporated in this design.
Glare emanating from the headlamps of vehicles approaching from behind can be detected using Gentex auto-dimming rearview mirrors that generate dim light with respect to the amount of glare detected, ensuring the driver with virtual assistance to move forward.
The new SmartBeam has been installed in BMW 3 Series, in a special "Light and Sight" package equipped with Xenon headlamps.
