What is the purpose of a car night vision system?

Car night vision system: Utilizes infrared technology to transform darkness into daylight-like conditions, allowing drivers to see farther and more clearly at night. The night vision system consists of two parts: one is an infrared camera, and the other is a light display system on the windshield. Here is information about car night vision systems: 1. The function of a car night vision system is to optimize the driver's field of vision. When driving at night, using this system allows the driver to better understand the surroundings of the vehicle. 2. It also prevents high beams from shining on the vehicle, which can cause glare for the driver, and improves the driver's ability to discern objects in conditions like heavy fog or sandstorms. For example, some drivers with poor driving habits prefer to use high beams at night. When high beams shine on the driver, it can cause glare and lead to unnecessary traffic accidents.
The automotive night vision system primarily helps us see road conditions clearly at night or in poor lighting. It uses infrared cameras to detect heat signatures of objects ahead, converting temperature data into images displayed on the dashboard or windshield, capable of identifying pedestrians, animals, or obstacles over 100 meters away. I've personally experienced its benefits when driving at night, especially on unlit rural roads where standard headlights only illuminate a few dozen meters - this system feels like gaining night vision. It provides early warnings about potential hazards like jaywalking pedestrians or deer standing in the road, giving drivers ample time to brake or change lanes. Particularly during rainy or foggy conditions with low visibility, this system proves far more reliable than human vision, significantly reducing nighttime driving fatigue.
I really like the night vision feature in my car, and its practical performance is impressive. It primarily uses thermal imaging to detect living creatures in the dark. For example, people wearing dark clothes walking at night, who are invisible under ordinary headlights, are highlighted with yellow frames on the screen. Once, while driving on a mountain road, I encountered a group of wild boars. If I hadn't spotted the heat sources on the screen 100 meters ahead, I might have hit them. Nowadays, many new cars also come with pedestrian recognition and alert functions, automatically flashing warning lights when detecting potential dangers. The entire system doesn't rely on visible light, making it effective even in foggy or snowy conditions. It gives me much more confidence when driving long distances at night.
Simply put, a car night vision system helps us see things in the dark. It comes in two types: passive systems that receive infrared radiation emitted by objects themselves, and active systems that emit their own infrared light. A processing chip converts thermal signals into black-and-white or color-coded heat maps displayed in the cockpit, with cold objects appearing darker and hot objects brighter. This allows drivers to clearly distinguish the outlines of living beings, such as cyclists by the roadside or suddenly appearing cats and dogs. The system typically has a detection range three times longer than headlights, proving particularly useful on unlit national highways. While it can't replace cautious driving, it does provide valuable reaction time.
