LED accelerates the development of driverless cars

Intel scientist Richard droberts revealed that he is working to establish a set of IEEE regulations to guide automotive visible light communication (VLC)The future development of. VLC makes visible light emitted by LED using car headlights, thus making it possible to create a low-cost car mesh network. Intel has been devoted to VLC research since 2008, and Roberts is seeking to develop this technology into a communication platform between cars. Roberts is an advocate of the system, and his colleagues are trying to use a series of rapid pulses of visible light to realize the transmission of information between cars. The pulse of this LED flash is so short that human eyes cannot feel it, but it can provide other cars with information about traffic conditions along the road, possible collisions, etc. and can become part of the unmanned system. Although the data rate of data transmission from one car to another is low enough, common cameras can be used to obtain it, and LEDs already used in cars today can transmit these data. VLC is a cheaper choice than all new cars equipped with radars or lasers. Although radar and lasers are more efficient ways to make cars aware of the surrounding situation, they are also expensive ways in price-sensitive markets. To make a basically feasible mesh network scheme, at least 10 cars on the road need to be equipped with radar or laser systems. VLC depends on the line of sight (line-of-sight) This is a disadvantage compared to radar or wireless networks, because bad weather and ambient lighting conditions will interfere with LED flash, which makes VLC less feasible as a spontaneous drive technology solution. However, VLC can provide additional protection functions for future driverless cars and accelerate its development process.
