Toyota Vehicles to Feature Next-Generation LED Array Lighting from 2015
Toyota City, Japan, November 26, 2014―Starting next year, some of Toyota Motor Corporation's new models will feature a newly-developed adaptive high beam technology that enables more precise control of light distribution through independent LED control.
The new LED Array Adaptive High Beam System (LED Array AHS) uses multiple independently controlled LEDs arranged in a single row, giving a wider range of illumination than earlier systems1 without dazzling the drivers of preceding and oncoming vehicles. For example, LED Array AHS can illuminate the gaps between preceding vehicles and oncoming vehicles, making it easier to detect pedestrians crossing the road. It also adapts the distribution of light to a wide range of driving circumstances: in an urban setting, for example, a wide area will be illuminated, whereas long-distance illumination is used during high-speed driving. The system also adjusts the distribution of light based on the operation of the steering wheel, improving visibility ahead of curves. LED Array AHS combines these functions to provide reliable illumination during nighttime driving.
Last year, 4,373 fatalities were caused by traffic accidents in Japan alone. Although the number of annual traffic fatalities has dropped for 13 consecutive years, pedestrians constituted the largest group of fatalities, and approximately 70 percent2 of pedestrian fatalities occurred at night. Toyota's development of next-generation illumination technologies is part of the company's efforts to help prevent accidents at night. In addition, the all-new Toyota Safety Sense active safety package, to be rolled out from 2015 onward, will feature Automatic High Beams3 (AHB) as standard.
How LED Array AHS Works
Illumination Optimization
Toyota believes that the ultimate goal of a society that values mobility is to eliminate traffic fatalities and injuries. Toyota's Integrated Safety Management Concept sets the direction for safety technology development and vehicle development, and covers all aspects of driving by integrating individual vehicle safety technologies and systems rather than viewing them as independently functioning units. This approach is reflected in R&D focusing on safety devices and systems.
Toyota is firmly committed to a wide range of initiatives addressing traffic safety, ranging from the development of ever-safer vehicles and technologies to helping create a safe traffic environment and engaging in educational activities.]
Nice! This is what Audi was going nuts over last year cause this technology is illegal in the U.S. right?
That was my thought also. It seems to be very similar to the tech that Audi was going gaga over last year (but that is part of Audi's overall "highly innovative" image they wish to present). And, yes, it is illegal in the US (and Canada, also, I suppose) because American regulations do not allow active headlights.
Its not that specifically the US regs don't allow active headlights. The law was written back before anybody had any idea what an active headlight was. The code says that a vehicle may only have two modes to its headlight aim, regular, and high beam. The statute they are quoting dates back to the 1970s.

considering Lexus is going to offer it in the US in new RX, it is not going to be illegal or they engineered it around the laws... lets us also keep in mind that Lexus was first on the market with selective lighting tech, with LS that was sold in Europe and Japan since 2012.

This may be similar to the new LED light systems MB had on the 15 CLS (not active but they do have a dazzling led array). They can use this in conjunction with traditional fixed halogen/hid headlight systems. Audi was arguing because they wanted it to be the only front lighting system on their vehicles.

it has that this has a focusing lens that swivels while MB system lights up different fixed leds based on camera/nav whatever else... at least after looking at both pdf's.
