Navigate ASIL Levels for Successful ISO 26262 Certification
The car industry is seeing a surge in new technologies. Electric vehicles packed with thousands of lines of code and advanced systems are becoming more common. These systems include things like Adaptive Cruise Control, LiDAR-based driver assistance, and X-by-Wire braking. To make sure these cars are safe to use, car makers have to follow international rules. One of these rules is the ISO 26262 standard.
What is ISO 26262 certification?
This strong standard first came out in 2011 and was updated in 2018. It’s all about making sure the electrical and electronic systems in cars on the road are safe. Part 6: Software Development mandates methods such as MC/DC coverage for high-ASIL software. Part 9: ASIL assessment steps define the Automotive Safety Integrity Level methodology via Hazard Analysis & Risk Assessment (HARA).
Why ISO 26262 Certification Matters
The certification process helps in a bunch of ways, such as giving your suppliers a nice boost in credibility, and it makes working with OEMs (Original Equipment Manufacturers) a lot smoother. Plus, the whole process is pretty thorough, too. It involves spotting potential hazards, figuring out Automotive Safety Integrity Levels (or ASIL levels), and then creating and testing both software and hardware to make sure everything’s safe and sound.
The ASIL Levels: the backbone of functional safety in automotive
The ASIL levels range from A to D. Eachlevel corresponds to risk severity, exposure, and controllability.
| ASIL Levels | Description |
| A | Low Risk (e.g., cabin light) |
| B | Moderate Risk |
| C | High Risk (e.g., early warnings) |
| D | Highest Risk (e.g., Braking) |
The framework for the ISO 26262 certification process
- Planning and assessment:
Initiating the functional safety lifecycle, by establishing a safety management system, defining scope, extracting assumptions and constraints, and identifying the “item” (system/hardware/software) that should be assessed.
- Hazard analysis: Application of HARA to identify and assess hazards (severity, exposure, controllability), and map each to an ASIL level from A to D.
- Implementation process: At the software development stage, the teams can implement codes adhering to coding standards such as MISRA C, unit-test for coverage, and MCDC, and integrate modules.
Benefits of ISO 26262 Certification
- Well-planned safety measures cut down accidents and dangers in the car industry.
- The process becomes more refined, with better systems like tool testing and Failure Modes, Effects, and Diagnostic Analysis (FMEDA).
- It cuts costly fixes late in the game and problems after sale, saving millions in making and guaranteeing products
