ALTO, Calif., Sept. 9,
2024 /PRNewswire/ -- Hesai Technology, a global
leader in the lidar industry, has successfully passed a rigorous
audit by TÜV SÜD and obtained the ISO 21448 Safety of the Intended
Functionality (SOTIF) certification based on ISO 26262 functional
safety and a QMS framework. This makes Hesai the first in the
global lidar industry to receive this certification. It highlights
Hesai's advanced process system for safety and its integration of
best practices into research and development.
Since 2021, Hesai has focused on creating a "3-in-1" safety
system that combines functional safety, SOTIF, and cybersecurity
within its lidar product design. As the first company in the
industry to achieve certifications in ISO 26262, ISO/SAE 21434, and
ISO 21448, Hesai's "safety triangle" guarantees precise and
reliable data input for intelligent driving.
Safety is the foundation of intelligent driving, and as
autonomous driving technology advances, perception hardware like
lidar faces increasingly stringent safety requirements. Lidar's
role as a key sensor makes it vital to overall vehicle safety.
SOTIF for lidar includes analyzing functional limitations,
particularly under conditions like bad weather, vibrations, and
electromagnetic interference. Hesai continuously optimizes lidar
design to mitigate these factors, ensuring safety in complex
environments.
ISO 21448:2022, "Road vehicles - Safety of the Intended
Functionality," is the first SOTIF standard established by the
International Organization for Standardization (ISO). The standard
ensures that various operational scenarios are considered during
design and operation, mitigating potential safety risks from system
performance limitations or human error.
By studying relevant standards, regulations, and best practices,
Hesai has built a scenario library dimension table for testing
perception features driven by lidar data. This table
comprehensively covers seven core categories, including vehicle
operating scenarios, environmental conditions, and sensor states,
subdivided into hundreds of specific scenarios, evaluating lidar
performance from all angles and reducing the likelihood of
unknown hazardous states. This enables the system to remain safe in
a broader range of scenarios.
For instance, Hesai's proprietary active interference rejection
technology independently encodes each laser pulse, effectively
isolating interference from external lidar signals. Additionally,
Hesai's dirt diagnosis feature identifies and reports dirt on the
lidar's window, converting dirt into actionable data for
intelligent driving systems, which enhances lidar safety and
stability in practical applications.
Another breakthrough from Hesai is the world's first Intelligent
Point Cloud Engine (IPE), which marks and filters out more than
99.9% of environmental noise, such as rain, fog, vehicle exhaust,
and dust, in real-time. This technology significantly reduces
misidentifications and false triggers, making lidar more stable in
adverse conditions.
Hesai's SOTIF certification, based on ISO 26262 functional
safety and a QMS framework, enhances intelligent driving by
clarifying system limitations caused by interference. This approach
enhances the safety of the intelligent driving system,
significantly expands the operational design domain, reduces the
need for takeovers, and improves both user safety and driving
experience.
