· ASIL D is the highest level of ISO 26262 certification and recognizes compliance with most stringent measures to prevent and mitigate safety-related failures.
LG Electronics has secured its first Automotive Safety Integrity Level D (ASIL D) product certification for an automotive central gateway system, strengthening its position in the development of safety-critical vehicle technologies.
The certification was awarded by global testing and certification organisation TÜV Rheinland for LG’s central communication unit (CCU) 2.0, developed for the Genesis GV90.
It also marks the first ASIL D product certification issued by TÜV Rheinland in the automotive central gateway system category.
ASIL D is the highest safety classification under the ISO 26262 functional safety standard, which governs the development of electrical and electronic systems used in road vehicles.
The classification requires manufacturers to implement stringent measures to identify, prevent and mitigate potential safety-related failures.
During the certification process, TÜV Rheinland assessed LG’s development procedures, design documentation and verification results to establish whether the system met the applicable ASIL D requirements.
From certified processes to product-level safety
The achievement builds on LG’s efforts to strengthen its functional safety capabilities in the automotive industry.
The company obtained ISO 26262 process certification for its automotive development framework in 2017 before securing ASIL B product certification for its advanced driver assistance system (ADAS) front camera module in 2021.
The latest recognition demonstrates LG’s ability to apply the highest functional safety requirements throughout the design, development and verification of an automotive product.
For global automakers, independent product-level certification provides additional assurance of a supplier’s ability to develop safety-critical vehicle systems. LG expects the achievement to strengthen its competitiveness in future automotive platform programmes.
How LG’s central gateway system works
LG’s central gateway system functions as a communication hub within a vehicle, connecting electronic control units (ECUs) and managing data exchange across internal and external networks.
The system uses controller area network (CAN) and Ethernet interfaces to route information between vehicle components.
It is designed to transmit safety-related messages accurately, identify communication and routing malfunctions, and relay relevant fault information to other electronic control units.
The technology also incorporates functional safety measures for over-the-air (OTA) software updates, helping prevent unintended updates and maintain safe vehicle start-up during software updates and rollbacks.
Beyond communication management, the system supports connected car services, features on demand and vehicle diagnostics.
It also incorporates cybersecurity capabilities, including intrusion monitoring and certificate-based authentication, to help protect vehicle systems and communications.
Positioning for next-generation vehicles
As the automotive industry shifts towards AI-defined vehicles (AIDVs), central gateway systems are becoming increasingly important in managing communications across complex vehicle networks.
These systems support software updates, connected services and the exchange of information between vehicle components, making functional safety a critical consideration in their development.
LG says the expertise gained through the project can be applied to other safety-critical automotive technologies, including next-generation communication control systems, gateways and domain controllers.
The company also plans to build on its functional safety development processes, design capabilities and verification methodologies to expand its automotive solutions portfolio.
“Earning our first ASIL D product certification is a significant milestone for LG,” said Lee Sang-yong, head of the VS R&D Laboratory at the LG Vehicle Solution Company.
“It reflects our progress from establishing certified functional safety processes to implementing and verifying the highest-level safety requirements in an automotive product. We will build on this accomplishment to strengthen automakers’ confidence in LG and advance next-generation solutions for the AIDV era,” he added.
