Hesai Technology, a leader in the global lidar industry, has become the first company in the industry to obtain the prestigious ISO 21448 Safety of the Intended Functionality (SOTIF) certification. This certification, issued by TÜV SÜD, emphasizes Hesai’s commitment to functional safety and the development of advanced, safe lidar technologies for intelligent driving systems. Their certification is based on the ISO 26262 functional safety standards and a QMS framework, reflecting Hesai’s innovative safety practices in lidar technology.
Key Highlights:
- First in the global lidar industry to receive ISO 21448 certification.
- Certification underscores advanced safety systems based on ISO 26262 functional safety.
- Hesai’s “3-in-1” safety system integrates functional safety, SOTIF, and cybersecurity.
- Developed an extensive scenario library to test lidar performance under various conditions.
- Pioneered active interference rejection technology to filter out external lidar signals.
- Intelligent Point Cloud Engine (IPE) reduces environmental noise by over 99.9%.
Hesai’s commitment to safety is foundational to its innovations in autonomous driving technologies. Since 2021, the company has developed a comprehensive safety system that integrates functional safety, SOTIF, and cybersecurity. This “safety triangle” ensures that their lidar systems provide precise and reliable data necessary for autonomous driving. The company’s advancements in safety have positioned it at the forefront of lidar technology, especially in the face of stringent safety demands from evolving autonomous driving systems.
The ISO 21448:2022 standard plays a crucial role in enhancing safety by ensuring that operational scenarios are thoroughly evaluated during design and operation. For Hesai, this includes analyzing potential functional limitations under conditions like poor weather, vibrations, and electromagnetic interference. As a result, Hesai’s lidar products are optimized to perform safely in these challenging environments, furthering the company’s leadership in lidar technology.
To ensure safety in all scenarios, Hesai has developed a scenario library dimension table that evaluates lidar performance across hundreds of specific conditions, including environmental challenges and vehicle operating states. This extensive testing allows the system to operate safely across a wider range of scenarios, reducing the risk of unknown hazardous states.
Some of Hesai’s most notable technological innovations include active interference rejection technology and the Intelligent Point Cloud Engine (IPE). Active interference rejection isolates lidar signals from external interference, while the IPE filters out over 99.9% of environmental noise in real-time, such as rain, fog, and dust. These breakthroughs significantly improve the stability and reliability of lidar systems in real-world applications.
The ISO 21448 certification further enhances Hesai’s lidar technology by addressing the limitations caused by interference and system performance. As a result, their systems expand the operational design domain, reducing the need for human intervention and improving overall safety for autonomous vehicles.
Hesai’s innovations and safety-first approach have not only set new industry standards but have also strengthened the safety and performance of intelligent driving systems.
