existcarIn the electronics industry, ISO 26262 and AEC-Q are two highly-watched international certification standards. They each have different certification objects and focus, and complement each other, giving full play to the value of overall significance in improving the safety and reliability of automotive electronic systems.

ISO 26262 Certification: Guardian of Functional Safety

ISO 26262, full name "Road vehicles-Functional safety",yescarThe industry's functional safety standard, which is designed to ensure the safety of automotive electronic and electrical systems, identify, evaluate and control potential risks through a systematic approach to achieve acceptable levels of residual risk.ISO 26262 certification focuses not only on singleComponentsThe security of the entire system pays more attention to the functional safety design.

ISO 26262 certification is widely used, includingcarDevelopment process of electronic systems, products (entity or non-entity), software, etc.The certification process includes multiple stages such as security analysis, security requirements formulation, system design and development, verification and verification activities, internal audit and external review.Ultimately, the certification body will issue an ISO 26262 certification certificate to prove that the company's development process or the functional safety design of the product itself meets the standards.

fromcarFrom an industry perspective, ISO 26262 certification is not only of great significance to improving the safety of automotive electronic systems, but also promotes the improvement of the overall technical level and innovative development of the automotive industry.Through the system's hazard analysis, risk assessment and functional safety design, ISO 26262 certification effectively reduces the failure risk of automotive electronic and electrical systems, reduces traffic accidents caused by system failure, and ensures the safety of life and property of passengers and road users in the car.

AEC-Q certification:ComponentsGuarantee of reliability

AEC-Q certification, full namecarAutomotive Electronics Council Certification, specifically targetedcarelectronicComponentsReliability testing certification.AEC-Q certification was launched by the U.S. Automotive Electronics Commission in 2000 and has now become one of the certification standards widely recognized by the global automotive industry.

The main objects of AEC-Q authentication arecarelectronicComponents, such as integrationchip, separatesemiconductor, passive devices, etc.TheseComponentsIt needs to be rigorously tested to ensure reliability and stability in on-board applications.The test content covers electrical performance, environmental adaptability, mechanical strength, reliability and consistency.After the test is passed, you can indicate that the AEC-Q compliance can be made in the product manual.

AEC-Q certification is improvingcarelectronicComponentsIt has a positive effect on quality and reliability.By establishing and implementing strict certification standards, AEC-Q certification can ensure the quality and reliability of automotive electronic components.At the same time, through supply chain management and product verification, AEC-Q certification can prevent unqualified raw materials and parts from entering the production process, thereby reducing product quality risks.

ISO 26262 Contact with AEC-Q Certification

The goals are shared:Both ISO 26262 and AEC-Q certification are committed to improvingcarThe safety and reliability of electronic systems ensure the safety and reliability of the vehicle.

Stepping improvement:AEC-Q certification ensurescarelectronicComponentsThe reliability and stability of the ISO 26262 certified functional safety design provides a solid material basis.Therefore, the overall system uses components that have passed AEC-Q certification, which can basically be regarded as a basis for passing ISO 26262 certification.To achieve ISO 26262 certification is the "ticket" for the automobile supply chain.

Differences between ISO 26262 and AEC-Q certification

Authentication object:AEC-Q certification is mainly aimed atcarelectronicComponents, while ISO 26262 certification focuses more on the functional safety design of automotive electronic systems, including development processes, products (physical or non-entity), software, etc.

Certification standards:The AEC-Q certification standard is mainly based onComponentsReliability testing includes electrical performance, environmental adaptability, mechanical strength and other requirements.The ISO 26262 certification standards pay more attention to functional safety design, including requirements in hazard analysis, risk assessment, safety goal setting, safety requirements formulation, system design and development.

Certification process:AEC-Q certification is only forComponents Products, including integrated circuits, discrete devices, etc., are designed to consider the rigorous working conditions that a specific device may be in.The process of ISO 26262 certification is more complex, including multiple stages and links, and the certification certificate is finally issued to prove that the company's development process or the functional safety design of the product itself meets the standards.

Crossing the certification threshold, the proportion of domestic car cores will increase rapidly

Our countryNew energyThe car industry needs strongchipSupply chain "price protection".Multiple data are counted in different caliberscarAlthough the current chip self-sufficiency rate of the industry varies, it is generally concentrated around 10%, which shows that the self-sufficiency level of the car core still has a lot of room for improvement.

In terms of technical strength, our countrychipThe company has made huge breakthroughs in the automotive core field.In addition to the smart cockpit main chip that uses advanced processes, there are huge MCUs,sensor, signal chain and power supply simulation devices are all made using mature processes, and now have strong production capacity in the local area.

The reason why the current self-sufficiency rate is still low is mainly because many companies and products are in a long certification process.Judging from the rigor of ISO 26262 and AEC-Q certification, the number of testing links and the length of the process must be calculated in years.

In recent years, domestic key solutions have been madechipSupply chain security issues, these chip products that have long been "started" are not far from completing all certification steps, and will be invested in the supply chain to supply locally.carIndustrial use.The chip self-sufficiency rate of the local automobile industry will soon be greatly improved.


To sum up, ISO 26262 and AEC-Q certification arecarElectronic systems are of great significance, and they are committed to improving the safety and reliability of automotive electronic systems.As for the local industrial chain, more and morechipComplete the certification process with system-level products, which will directly promote the domesticNew energyCars have achieved better development and will exert their influence to a further market space.
