This is "transparency" a? Column-Nezha, the second production car of Nezha Automobile? u？ Innovative design.
Transparent "a"? The column design broke the car? Answer? Time-honored column design method.
Prior to this, although Toyota and Volvo tried to remove it by refractive materials or hollowing out? Answer? The vision of the column is blind, but these technologies have not been mass-produced on buses so far.
Where is Continental Group? 20 18? Launched with Nezha in 2008? u？ A similar "virtual" A? Column technology, so far there is no news of formal mass production.
Since the world's top auto parts suppliers can't mass-produce, Nezha? u？ Why can you do it?
1. Try to "punch through" one? pillar; mainstay
Usually a car will have it. Answer? Column, b? Column sum? c？ Column design, yes? MPV？ Will there be more models? d？ Pillars, these structures are the main part used to support the strength of the vehicle.
Among them, a? Column refers to the connecting column connecting the roof and the front cabin of the vehicle at the left and right front. Because it is close to the driver and the co-driver, this part of the structure is very important for the safety of the vehicle.
Answer? The main function of the column is to prevent collision, but it also blocks the driver's sight to a certain extent, which is a natural contradiction. Especially at low speed, when the vehicle turns left, it will have a great impact and sometimes even cause an accident.
In order to reduce this risk, car companies and suppliers began to try? Answer? This column has been optimized.
The optimization ideas of the industry mainly include:
Toyota A-pillar Refractive Material Patent
First, use the principle of physical refraction of light, will it? Answer? The column is "transparent"
Toyota said in a patent application document, "This technology requires cameras and some expensive materials and equipment, so it has not been put into practical use. But now the patented equipment acquired by Toyota has reduced the cost. 」
The second is change? Answer? Column modeling design, to achieve penetration? Answer? The effect of the column. Volvo put forward the hollow design and passed it. Answer? Hollow out the interior of the column to realize grid-like entity and alignment. Answer? Observe the road conditions outside the column.
Virtual of Continental Group? Answer? Column technology
Third, through cameras, display screens and other technologies? Answer? "Virtualization" column.
Continental Airlines released a "virtual" A? Column? (Virtul？ A-Pillr) technology, mainly through the panoramic camera of the vehicle and in? Answer? Embedded in the column? Organic light emitting diode? The display screen * * * cooperates with each other to let the driver pass? Organic light emitting diode? The screen observes the external environment of the vehicle in real time. At the same time, the mainland scheme also provides a dynamic perspective by monitoring the driver's head movement.
All the above technical ideas are novel, but they have not been mass-produced in the end.
So, what is the optional price? 1.2? Ten thousand yuan, Nezha? u？ "transparent" a? How did the column of mass production get on the bus?
Actually, Nezha? u？ "transparent" a? The column scheme is similar to that of Continental Group, and the hardware includes such things as? Organic light emitting diode? Screen, camera and other components, the software level is equipped with a set called? AR-view？ Behind the system is a set of intelligent software algorithms.
As you can see, four dollars? Organic light emitting diode? Where is the screen installed? Answer? In the column, two on the left and two on the right. Outside the vehicle, high-definition cameras are installed on the left and right to collect data. Answer? External information blocked by the column.
There is a camera above the center of the steering wheel in the car to detect the movement of the driver's head.
Finally, through the software algorithm, let? Organic light emitting diode? Can the screen reflect in real time? Answer? Road information outside the column, realization? Answer? The "transparent" effect of the column, thus avoiding visual blind spots.
Specific to the use of links, "transparent" a? This column will automatically switch according to the vehicle speed, and the system will automatically start when driving at a low speed, at which time the driver can pass the car. Organic light emitting diode? Real-time screen observation? Answer? Column blind area information, the system will automatically shut down when driving at high speed.
Behind the hardware equipment, but also involves the software level? AR-View？ Systems and algorithms.
Judging from the available information, Nezha? u？ "transparent" a? Is it used in column functions? AR？ Technology and eyebrow algorithm.
Where is it? u？ "transparent" a? In the column function, AR-View? The system collects real-time information outside the car through a high-definition camera and displays the information inside the car? Organic light emitting diode? On the screen.
It is worth noting that in order to ensure the smoothness of the picture, the system adopts the strategy of reducing the clarity of the picture.
"transparent" a? The column adopts the eyebrow center algorithm, that is, the camera installed on the steering wheel detects the moving position of the driver's eyebrow center, so as to adjust it automatically. Organic light emitting diode? Screen viewing angle.
Simply understand, this "transparency? Answer? "Is actually a kind of column? AR？ Technology, the principle is to put? Organic light emitting diode? Where is the flexible screen installed? Answer? Inside the column, it works through external cameras and software algorithms.
The mystery lies in a set of "eyebrows algorithm", which will track the driver's eyes through the camera and calculate the position of the eyebrows, so as to make corrections? Answer? Confirm and display the display angle of the columnar display screen in real time.
But unfortunately, although Nezha? u？ Listed, but "transparent?" A-pillar "is not yet open for external selection. This means that consumers can't use this technology immediately.
2、AR？ Technology and organic light emitting diodes? Technology is maturing.
Generally speaking, Nezha? u？ "transparent" a? What is reflected behind the "Get on the Bus" column? AR？ And then what? Organic light emitting diode? The gradual maturity of technology.
AR？ Also known as augmented reality, through multimedia, three-dimensional modeling and other technologies, the real world information is seamlessly connected with the virtual world.
Where did this technology rise? 20? Century? 90? In 1980s, it was widely used in the fields of medical treatment, education and entertainment. In recent years, it also began to appear in the automobile field, such as the one released by Zebra Zhixing. AR- driving? Technology.
Realize? Answer? The transparency of columns is inseparable from the maturity of eyebrow algorithm.
What does the eyebrow algorithm belong to? DMS？ A branch of driver monitoring technology. Are you online? Adas? Market, by monitoring eye movements? DMS？ The technology has matured and started to be widely used in automobiles.
The principle of the eyebrow center algorithm is to locate the actual coordinates of the driver's eyebrow center, calculate the visual blind area, and adjust the external camera image corresponding to the visual blind area to achieve better transparency. Answer? Column or? HUD？ Fusion control effect.
Besides, carry it? Organic light emitting diode? Screen boarding has become the standard configuration of many car companies, and some new car-making forces, such as Baiteng Automobile, will even carry it? 48? Big screen, Audi? E-tron and Cadillac are also equipped? Organic light emitting diode? Screen plan.
Famous market research institutions? UBI？ Research? Guess, want it? 2020? Year? Organic light emitting diode? Will the screen occupy the car monitor market? 10%? Share it.
Nezha? u？ "transparent" a? Four pillars? Organic light emitting diode? The screen area is about * *? 24? Inches, although only observing the external situation of the vehicle, the requirement for clarity will not be as good as that of the central control panel, but the cost is also high.
However, for "transparency" A? For products like columns, some people in the industry expressed their concern about the car core, thinking that although the design is cool, there are also shortcomings:
Security issues. Although transparent? Answer? The column hasn't changed? Answer? The physical structure of the column, but the glass is easy to break after collision, causing harm to human body;
All kinds of extreme weather. Because of the strong light and night fog in the driving environment of the vehicle, if it is transparent? Answer? If some parts of the column are not done well, it will interfere with the driver's sight.
Nezha? u？ "transparent" a? Inside the pillar? Organic light emitting diode? The brightness of the screen will be adjusted with the intensity of external light, which avoids the problem of disturbing the driver's sight to some extent. But for the risk of glass breaking after collision, we haven't seen how to realize the protection behind it.
Nezha? U "transparent" a? The appearance of the column is essentially that the automobile industry is using software algorithms to change the automobile hardware.
It is not only an attempt in the field of active safety, but also involves the transformation of safety and driving comfort by intelligent cockpit. So, along this line of thinking, "transparent" A? Will the column be popular?
