With the development of science and technology, driverless cars are getting closer to us and will be realized in the near future. In the future, everyone will be safe, and people need not look at the surrounding environment, but this is only a utopian idea.
But today, nearly half of all traffic fatalities occur at night, making it particularly important to increase road visibility at night.
Automotive OEMs, first-tier suppliers and light source technology providers in Europe and Japan have begun to enter the emerging market for adaptive remote-light systems (ADB).
According to Lumileds, when a car camera senses oncoming vehicles or pedestrians, the ADB can automatically adjust the lights so that a single led in the headlights darkens or moves the beam downward and horizontally.
"You can always put light on a high beam to provide maximum illumination," said Dirk Vanderhaeghen, senior director of global Strategic Marketing for automotive led Lumileds. When a driver comes in head-on, the ADB will automatically adjust the high beam. ”
In Europe, Vanderhaeghen said, the ADB has not only developed high-end car brands, such as Audi and Mercedes. Compact sedans such as Opel, Peugeot and Citroen are also expected to launch. Japan's Toyota has also invested a lot in the ADB. He added, "Even in China, we now see an enquiry from the ADB." ”
♦ Matrix Headlamps "cover up" oncoming vehicles while maintaining high beam lighting between the two cars and the left and right sides.
"Driving visual news," CEO and automotive Lighting Technology and market research expert Hector Fratty said the ADB is "automotive lighting the biggest innovation." The Fratty is expected to rise to 15% by 2025, although the current share of the car is now a 1% per cent of the global car market.
For most drivers in the United States, what the ADB is, they don't know. Because the ADB is banned in the United States, the Federal Motor Vehicle Safety Standards Agency (FMVSS) requires discrete high beam and low beam settings.
Technology vendors like Lumileds hope this will change soon. At present, the National Highway Traffic Safety Administration (NHTSA) is reviewing the ADB, and some suppliers are expected to approve the U.S. Congress in 2018, the most late 2020 years.
Last year, the Automotive Engineers Association (SAE) released a report for the ADB "testing procedures, performance requirements and design guidelines," SAE concluded:
"The development of automotive technology has realized the active control of road illumination, which can dim or remove part of the beam according to oncoming vehicles and/or its surroundings." With the development of vehicle deviation warning, automatic remote light activation and other functional technologies, cars can identify and locate other vehicle road users at night and can actively limit glare. ”
Asked about the technology the ADB needed, Magney said: "The ADB system uses rather sophisticated algorithms to make lighting decisions." A powerful ECU is also needed to run the algorithm and perform calculations. In addition, different wiring is required, depending on the purpose of the camera.
