/ Aswen/August 25, 2022 GUANGZHOU - With the in-depth development of intelligent vehicles, intelligent driving technology has gradually become the focus of the industry. In late 2021, during a live link to the CEO Summit, Tesla CEO Elon Musk said, "The age of autonomous driving is coming and will be one of the biggest changes in the history of human civilization."
However, traffic accidents related to "autopilot" have been trending recently. The frequent occurrence of intelligent driving accidents indicates that the current intelligent driving system still has certain shortcomings in the level of safety. Adding new technical solutions may be a way of thinking. It is reported, including GaC Aean, the Great Wall, Changan and many other car companies are promoting infrared sensors on the car, the use of life body thermal radiation imaging infrared technology will be the last piece of intelligent driving safety puzzle?
Infrared technology may complement the key link of the Great Wall of intelligent driving safety
At present, mainstream new energy vehicles are equipped with Lidar, 4D millimeter wave radar, camera and other sensors. The Nextev ES7, for example, is equipped with 33 high-performance sensors, including one 1550nm Lidar, seven 8-megapixel cameras, five millimeter-wave radars and 12 ultrasonic radars.
These mainstream sensors work together to handle most road conditions. For example, lidar can detect objects and pedestrians by firing lasers and obtaining target location information based on flight time. Cameras, similar to human eyes, can directly recognize information such as traffic lights and cars in front of them, so that the autonomous driving system can make corresponding adjustments.
However, most of the intelligent driving functions of new energy vehicles may face the challenge of "incapacitated" in complex scenes such as insufficient light at night and fog and rainstorm.
In March 2018, one of Uber's self-driving SUVs, while driving at night, struck a woman who was crossing the street. The main reason Uber's self-driving SUV hit the woman was that she was crossing the road in a shadow area not covered by headlights, and the car's cameras couldn't pick anything up.
Therefore, following Lidar and 4D millimeter wave radar, infrared thermal imaging sensors are increasingly becoming a key link to build a Great Wall of safety in intelligent driving industry. Infrared sensors use thermal radiation imaging of living organisms to provide clear insight into pedestrians and animals even at night when there is no light source. Tim Loeb, vice president of Seek Thermal, said: "Infrared imaging is a good solution to the problem that lidar, which is commonly used in autonomous vehicles, cannot detect the heat of an object to determine whether it is alive."
In addition, because the wavelength of infrared is longer than that of visible light, the penetration is stronger, therefore, in the fog, rain and other bad weather, infrared sensor can still be unaffected to identify objects.
< b> deep cultivation of infrared technology, Xuenyuan intelligent driving brought mature solutions for industryinfrared thermal imaging sensor can greatly improve the safety of intelligent driving of vehicles. In the past, infrared core technology has been in the state of foreign monopoly for a long time, after decades of development, our country has gradually overcome the key technology of infrared, and has been formed With a complete industry chain, technological breakthroughs have provided the prerequisite for large-scale loading of infrared sensors.
From the action of Autonavi infrared, previously used for military infrared technology, is now through its subsidiary Xuanyuan intelligent driving to complete the industrial chain layout of vehicle-mounted infrared solutions. It is understood that the infrared thermal imaging obstacle avoidance system of Xuanyuan intelligent driving can detect pedestrians and vehicles on the road, to achieve alarm, avoidance and other advanced auxiliary driving functions.
At present, Xuanyuan Zhidriving has a completely controllable batch production line of infrared detectors with independent intellectual property rights, with an annual output of tens of millions of uncooled infrared detectors, and has the ability of large-scale loading of infrared sensors.
The automatic driving infrared camera component launched by Xuanyuan Intelligent driving is suitable for secondary development, which has the advantages of hardware-level size, clear image and fast integration. Taking the wooden barrel effect as an example, the current intelligent driving safety system has shortcomings, and safety is the fundamental of intelligent driving. The addition of infrared technology can undoubtedly make up for this shortcoming.
< /p>Intelligent driving is the core of intelligent vehicles. Infrared thermal imaging sensors that can significantly improve the safety of autonomous driving of intelligent vehicles in complex environments such as insufficient light and bad weather may become another big "match point" in the automobile industry after Lidar.
