During the Geneva Motor Show, Dr. Hackenberg, the board member of Audi's technical development team, became one of the most sought-after top executives of the Audi booth, just because the Audi showed too many advanced technologies to make the boss more show. The opportunity to know your own technology. There are only two topics that the global media are eager to learn: Audi's laser headlights and unmanned driving, and Dr. Hackenberg gives a very brilliant answer: About laser headlights: Laser headlights are a kind of face The new lighting technology of the future. At present, Audi has promoted LED lights, the most advanced of which is matrix LED headlights. This matrix LED headlights are composed of several LEDs that can illuminate different areas in front of the car. Just like the display screen, it consists of several pixels, and our LED is equal to one pixel, through which we can systematically illuminate different areas in front of the car. For example, when there is a car on the opposite lane, in order to avoid the dazzling of the driver of the opposite vehicle, the matrix LED headlights can only make the area in front of our own car bright. Of course, the laser headlights also have great advantages, especially the intensity of the light is larger than that of the LED lights. The distance it illuminates is also farther than that of the LED lights. At present, the distance of the LED headlights is about 350 to 400 meters. The laser headlights are 600 meters. The laser headlights that we participate in Le Mans's car are illuminated at a distance of 800 meters. This is very important for the driver and the driver during the race. In the future, our research and development work on laser headlights will continue, and there will be great breakthroughs. For example, we will develop matrix laser headlights in the future. This is the same as a matrix LED headlight that can illuminate different areas in front of the car, but this new technology is still far away from us. About driverless: In the future, autonomous driving or autonomous driving will become a very important and key new technology that can greatly improve the safety of driving. Under normal circumstances, the driver will be full of energy and have the ability to control the vehicle well; but once the driver is tired, it is easy to make mistakes. Automatic driving is to make up for the shortcomings of human fatigue and distraction. It will never fatigue, so I think that the introduction of autonomous driving can greatly improve the safety of driving in the future. Of course, this complicated technology takes years of research and development time. At the beginning, there may be some problems. It is not perfect when it is born, but the problem will be less and less. Of course, in the field of autonomous driving systems, we also attach great importance to cooperation with the IT industry. Because the IT industry can provide chips, storage, semiconductors, etc. with sufficient computing energy for the autopilot system. Now in this field, we have also participated in the early research and development of the IT industry.
Jin Yuankang vacuum sputtering, usually refers to the magnetron sputtering, belongs to the high speed low temperature sputtering method. The process of vacuum around 1 * 10-3Torr, 1.3 * 10-3Pa vacuum argon filled with inert gas (Ar), and the plastic substrate (anode) and metal material (cathode) between the plus due to high voltage DC glow discharge (glow, discharge) electron excitation produced by inert gas, plasma, plasma metal target atomic bomb, deposited on the plastic substrate. Compared with the commonly used sputtering deposition, sputtering and plating adhesion with substrate of strong adhesion than the high evaporation. More than 10 times, the advantages of uniform plating density. The vacuum evaporation need to make metal or metal oxide is vaporized, and the heating temperature is not too high, otherwise, the metal deposited on plastic substrate and exothermic gas Burn the plastic substrate. Several sputtered particles are not affected by gravity, the target and the substrate position can be freely arranged, film forming the initial nucleation density is high, the production of thin continuous film 10nm below the target, long service life, long time continuous production automation.
