Many car owners will encounter these problems when driving at night: they always feel that the brightness of the lights is not enough, the distance of the lights is too close, the road conditions are too clear, the roads are glaring, how can we solve these problems?
The collection time is from July 17th to August 20th.
Recently, the National Standards Committee, together with a number of automotive research institutes and automobile companies, drafted a draft of the National Standard Opinion Collection for Automotive Adaptive Front Lighting System (hereinafter referred to as the “Standardâ€). The collection time is from July 17th to August 20th, 2009. The online downloading opinions collection form is widely used to solicit opinions from all walks of life. After the collection of comments, it will be revised according to the feedback information and then released.
â– Developed with reference to European standards
The reporter interviewed Qian Qunlu, the head of the distribution department of the Technology Center of Shanghai Xiaohao Auto Lamp Co., Ltd., one of the drafting units of the Standard. Mr. Qian said: "In the developed countries and regions such as Europe and the United States [Review Photo Forum], the automotive adaptive front lighting system (AFS) has been developed since the mid-1990s [Review Picture Forum] in the mid-1990s. The common high beam and low beam lights are not only a combination of these different functions, but also extend these functions to better suit the lighting and safety requirements of different road surfaces."
It is understood that the "Standard" formulated by China is corresponding to the United Nations Economic Commission for Europe ECER123-00 "On the approval of the unified regulations for the installation of automotive adaptive front lighting system", applicable to passenger and cargo vehicles. Mr. Qian explained to the purpose of formulating the "Standards" in China: "Considering that the international regulations of the AFS system have been completed, and the domestic standards are in line with the international standards, it can effectively promote the domestic research and development of the AFS system and promote the development of similar industries in China. â€
â– Auto headlights can intelligently respond to road conditions
What is the adaptive front lighting system for automobiles? What is the role? Mr. Qian answered the reporter one by one: "The adaptive lighting system for automobiles is an adaptive lighting scheme for vehicles that can achieve four major functions: severe weather lighting, corner tracking, body trimming, and fault diagnosis. The AFS system utilizes variable optical system, electronic control, and follow-up system technology to automatically change the light shape of the front lights according to road and weather conditions, and direct limited light to places that need more illumination, greatly improving nighttime. Safety of driving.†The Standard divides the adaptive system into four modes: reference mode, highway mode, rainy mode, and town mode, each of which corresponds to a curve mode. For example, in highway mode, because the distance of the light is required, the adaptive system adjusts the angle of the light according to the demand, improves the line of sight distance, and enhances the driver's predictive power against the road ahead. In the rain mode, the light angle is automatically adjusted. To avoid the reflection of light and snow on the light, and the traffic environment is complicated. The driver needs a wider field of view at night to judge the road condition. Therefore, the lights will tilt to both sides to increase the area of ​​light illumination. The driver provides more accurate road information. When all modes are off, the reference mode is activated, but in each mode a "curve mode" is set independently to improve the cornering lighting requirements in each mode.
It is reported that the current domestic automotive products equipped with such systems are Audi A8, Lexus LS460L, New Regal 2.0T, Mercedes-Benz S-class 400, etc., but they are limited to their respective technical categories, and the functions of adaptive lighting systems are also different. The introduction of the "Standard" will end the situation of automakers in the independent lighting system.
Privately changed car lights
When driving at night, if the high beam is turned on, the driver will be dazzled and seriously threaten driving safety. Xi'an Traffic Police Detachment Section Jinhui police officer said: "Although the state does not specify the circumstances under which the car allows or does not allow the use of high beam, but the traffic accident caused by high beam glare is not uncommon. If in the city [review picture forum] Under the premise of sound public lighting system on the road, the traffic police department can educate or punish the vehicles that have turned on the high beam."
In addition, regarding the laws and regulations on automotive lighting systems, Jin Hui stressed: "Many car owners are currently adding enhanced lighting systems to their cars, such as xenon headlights, which are in violation of the law. Many of these products have technical specifications that exceed the state. Standards have brought hidden dangers to road traffic safety. Those cars that have modified the lighting system will not pass the annual inspection of the car. However, Jin Hui also pointed out: "The original enhanced lighting system is passed by the national inspection agency. Certified, so it is not illegal."
Finally, Jin Hui reminded the driver that when driving, in addition to complying with road safety regulations, it is also necessary to talk about “carsâ€. It is recommended that the owner should close the high beam when he is in the car, avoiding potential safety hazards to the other party or himself, and building a safe traffic. surroundings.
