In the industry, 2024 will be a year of fierce competition for smart cars. The night driving scene is still a key problem that needs to be solved urgently for autonomous driving. How can this priority be effectively addressed? Automotive thermal imaging technology is indispensable.

Application background of vehicle infrared thermal imaging technology
According to the data, the traffic accident rate at night is three times that of the day, mainly due to poor light conditions at night, poor lighting, and factors such as shorter and narrower field of view of drivers; In addition, glare, the "black and white hole effect" in tunnels, and the high beams of oncoming vehicles can cause the driver's judgment to deteriorate and increase the driving risk. Bad weather such as rain and haze can also cause visibility to drop dramatically, increasing the probability of traffic accidents.
Infrared thermal imaging technology uses infrared thermal radiation emitted by objects to generate images, which does not rely on external light sources and can work stably in any light conditions, including day, night, glare and other complex environments. In addition, because the infrared wavelength is longer and has the ability to diffract particles in the air, infrared thermal imaging technology can still provide relatively stable images in the face of severe weather and environments such as snow, fog, haze, and dust.
The "Eagle Eye" of on-board infrared thermal imaging intelligent driving
As early as the early 2000s, overseas car manufacturers such as Cadillac and BMW took the lead in deploying infrared thermal imaging technology on the vehicle side, in order to avoid collisions between vehicles and animals in poorly lit or foggy areas. In recent years, infrared thermal imaging technology has penetrated from millions of models to mid-to-high-end models.

As one of the pioneers in the field of automotive thermal imaging in China, Ruichuang Micro-Nano has reached fixed-point cooperation with a number of OEMs and autonomous driving companies, including BYD, Yuanhang Automobile, Didi Autonomous Driving, TuSimple Future, Plus, Tag Zhixing, Zhongke Huituo, etc. In December last year, Ruichuang Micro-Nano won the Geely fixed-point project, which will provide Geely with infrared thermal imaging night vision system cameras and other products.
In the driving assistance stage, infrared thermal imaging sensors can support some cost-effective models to take the visual route; In the L3 and above autonomous driving stage, safety standards are becoming more and more stringent, and multi-sensor fusion is the mainstream trend. The addition of infrared thermal imaging technology will further improve the redundancy and reliability of the system, making driving safer.
In the future, with the continuous progress of technology research and development of leading enterprises and the explosion of market demand, the cost of infrared thermal imaging technology will be further reduced, so that it can be more widely used in the automotive industry, so that more consumers can benefit from the safety and convenience brought by infrared thermal imaging technology.
