Regardless of regulatory barriers, automakers and federal policymakers are working together to introduce new lighting technologies in the United States. Imagine the picture of the future: you drive at night, the high beam lights are on, and you don't have to remember to turn them on, they will automatically light up. When the car approaches an oncoming vehicle, high-tech headlights (which can emit thousands of independent illumination points and use the data from on-board cameras and sensors to focus the beam) create black holes to protect the night vision of other drivers. Going down the road, a deer emerges from the woods and the lights are marked with a glimmer of light. Due to adaptive high beam illumination, potential disasters are avoided. In Europe, such systems can be used, and their present is the future of the world. If you're like most people, you probably won't think too much about car headlights, except for opening and closing, occasionally flashing. Michael Flannagan, a headlamp specialist at the University of Michigan's Transportation Research Institute (UMTRI), has extensively studied automotive lighting and he has discovered this. He said: Even professional drivers do not seem to understand the risks associated with darkness. We estimate that more than 2,000 people are killed each year due to the darkness, mainly pedestrians. They suddenly appeared from the darkness, so fast that the driver could not respond. Flannagan believes that part of the problem is drivers, even skilled drivers, who often do not make full use of the high beam. Data can be traced back to the 1960s to confirm this. He said that the low beam is designed to work at speeds of 35 to 40 miles per hour, so if you encounter a drunk, texting or other pedestrian, and you drive 55 miles, you won't have a hunch because there is not enough Lighting. In the United States, the annual car travels more than 3 trillion miles. Low light accidents may be more deadly to pedestrians than other types of traffic accidents, but not many. Despite this, accidents related to headlights have drawn attention, and the Highway Safety Insurance Institute (IIHS) introduced a headlight rating system last year. Not long ago, the organization released a report that rated more than half of the headlights of medium-sized SUVs in the US market as marginal or poor, with only two being good. Cameras and sensors are now used in conjunction with semi-automatic functions to auto-brake, keep the car fixed, and alert the driver when there is a car in the blind spot area. Unfortunately, the US's headlamp technology in the United States is not as advanced. Automakers such as Audi and Mercedes have developed headlights that improve the driver's night visibility and reduce glare for other drivers. However, current federal regulations (especially the Federal Motor Vehicle Safety Standard 108) present challenges to the adoption of this new technology. For example, Audi's Matrix Beam uses LEDs to separate light from a single laser, creating an infinite number of small beams that reduce glare at certain points and enhance the brightness of other points. Flannagan said: The US and European regulations are different in philosophy, and Europe covers most of the rest of the world. US regulations are based on manufacturer's own certification, not European type approval. This means that in the United States, companies have to prove that their products meet federal standards. The standard itself contains multiple pages of incomprehensible information: from which light emits colors, how to test lighting, light sources, and more. Flannagan said: The company is responsible for meeting this standard. If someone points out that the vehicle is not in compliance, the company has a responsibility to prove this. Compare the European approach. In Europe, the government certifies an independent agency to evaluate the manufacturer's technology. Engineers do not need to meet American-style experimental test standards, and engineers objectively evaluate the efficacy of the lighting system. In Europe, manufacturers send their vehicles to the test room, where the test room dispatches engineers to evaluate the lighting under real road conditions, one engineer observes the brightness on the car and the other engineer looks for inappropriate glare on the opposite car. . The type of road and other specific conditions depend on the test room. The US regulations are more specific. Flannagan said: The federal government will not delay. Everyone is using the resources of headlamp technology as much as possible. People are often reluctant to pay more for better headlights and have less interest in technology. Regardless of regulatory barriers, automakers and federal policymakers are working together to introduce new lighting technologies in the United States. For example, a few years ago, Toyota filed an application for adaptive beam technology with the National Highway Traffic Safety Administration. Last summer, after two years of deliberation, the Society of Automotive Engineers (SAE) recommended a shift from adaptive laser headlamp testing to field testing. Other manufacturers are also actively promoting regulatory change. Flannagan pointed out that the industry requires specification, but they just want the rules to be clear, which is very strange. In a self-certification system, in a self-certification system, clear rules mean that the possibility of being considered non-compliant at a later stage can be reduced. Implementing this feature on any car with a front-end camera is fairly straightforward. What you need is some kind of software.
