Car lights are also projectors, "tram" or transformed into "light car"? It turns out that cars can also create a "metaverse"


Since entering the second half of 2021, the term "metaverse" has become popular. Japanese social giant GREE announced that it would launch a metaverse business; ByteDance invested heavily in the acquisition of VR startup Pico; Microsoft announced an enterprise metaverse solution at the Inspire Global Partner Conference... Major digital technology giants have entered the game, and let The metaverse has become one of the hottest concepts of the moment.

According to public information, the Metaverse can be considered as a virtual world that is both mapped to and independent of the real world based on the traditional cyberspace and with the improvement of the maturity of various digital technologies. At the same time, the Metaverse is not a simple virtual space, but includes the network, hardware terminals and users into a sustainable and wide-coverage virtual reality system. The system includes both digital replicas of the real world and virtual worlds. 's creation.

It is worth noting that the current narrow-sense metaverse industry chain with VR and AR as the main body has many overlaps with functions such as AR-HUD (head-up display with augmented reality technology) and smart lights on cars, including chips, Optical components, imaging and display technologies, and more. The emergence of these functions also allows some drivers to "drive" in the metaverse.

At present, more and more models are equipped with AR-HUD. For example, the new-generation Mercedes-Benz S-Class, FAW-Volkswagen ID.4 CROZZ, WEY Mocha and other models launched this year are all equipped with AR-HUD. Among them, the official guide price of the 2021 FAW-Volkswagen ID.4 CROZZ Yaoye two-wheel-drive version equipped with this function is 242,888 yuan. This also means that consumers do not need to choose a luxury car to experience the feature.

It is worth noting that AR-HUD may have a greater use after fully autonomous driving. At this time, drivers who have gradually liberated their hands began to pursue more comfort and entertainment. People began to extend the car scene as a "third space", and AR-HUD can make the glass of the car become a source of information, entertainment and advertising. vector.

At the same time, this has also created a new port for various automotive electronics manufacturers, and even Internet manufacturers, who will consider how to make the information content easy to read, use and interact with on the car screen.

"The application of intelligent in-vehicle light technology will advance the in-vehicle display from the LCD screen era to the ultra-large-screen optical imaging era. Optical imaging can break through physical limitations and achieve a more immersive virtual large-screen experience." Huawei Smart Car Solutions BU Chief Operation Officer Wang Jun said at the 2021 World New Energy Vehicle Conference that with the increasing requirements for bandwidth and security in automotive architecture, it is not ruled out that the communication system in the car will shift from electricity to light in the future, and the "tram" will also transform For the "light car".

Let the lights have the ability to "speak"

In addition to enabling interactions inside the vehicle, optical imaging can also extend beyond the vehicle. For example, the models of Mercedes-Benz, Volkswagen, WEY, China Express and other brands use digital projection lighting technology to turn headlights into "high-definition projectors" and have the ability to "speak" to provide people inside and outside the car and other vehicles. interact.

Specifically, the most common function that digital projection lighting technology can achieve is that when a vehicle passes through a narrow road section, the left and right headlights with high resolution can simultaneously emit two high-brightness lines of the same width as the vehicle, and the two lines The curvature of the synchronous adaptive steering angle helps the driver evaluate the driving route and passing ability.

It is worth noting that the purpose of the projection near the driver's line of sight is to effectively warn the driver so that the driver is not distracted because the reminder is elsewhere. In the real test process of night traffic testers, it can be more clearly perceived than the same warning message displayed on the head-up display.

In addition, the digital projection lighting technology can also realize the "light zebra crossing" projection function. When the vehicle encounters a pedestrian crossing the road, the headlight will project a "zebra crossing" on the road ahead, prompting pedestrians to rest assured; when the vehicle detects the distance of the vehicle ahead When it is less than the safe value, the front vehicle collision warning function is activated, and the headlights will project a white high-brightness prompt line to the road ahead of the driver's field of vision, and gradually reduce to a high-frequency flashing warning.

It is understood that these functions are automatically activated after the vehicle sensors analyze the driving situation. When a camera or sensor system on the vehicle detects a change in road information, the core processor can evaluate the data and a digital navigation map within milliseconds, providing commands to the headlights to optimally adapt the light distribution in all situations.

Some people say that it is not difficult to realize these cool demonstrations. For car companies, it is more important whether this projection system with a micromirror matrix can adapt to the way of the automobile industry to achieve mass production. All system components must meet the mechanical, electronic, chemical, thermal and optical standards for automotive conditions and be designed to meet the needs of the vehicle. And close cooperation between all parties in the industry chain, from developers of microelectronic components to lighting system developers and car manufacturers, will be necessary for products to be ready for mass production.
