To all those Functional Safety Engineers, who are immersed too deep inside the ISO26262, buckle your seat belts! Let us take a tour outside the 26262!!
The ISO26262 primarily focuses on “System” Safety. However, the overall Safety in the context of car is far beyond just system safety. It is about measures and features that are designed to minimize the risk of accidents, protect vehicle occupants, and reduce the severity of injuries in the event of a hazardous situation. It covers various aspects of vehicle design, technology, driver assistance systems and even environmental aspects that are aimed at both preventing accidents as well as to minimize injuries and harm in the event of an accident.
Automakers and regulatory bodies have taken continuous efforts to improve Safety standards, implement newer technologies and develop safer designs, and hence several standards have also been introduced. We can broadly group these standards into the following buckets:
- System Safety (which includes component safety)
- Technology Safety
- Vehicle Safety (which covers regulations and safety ratings)
- Manufacturing Safety

- Improved Automotive Component Reliability: The AEC-Q standards ensure that electronic components used in vehicles meet stringent reliability requirements. Reliable components help maintain the proper functioning of critical safety systems, such as braking, steering, and airbag systems.
- Quality Management System: The AEC-Q standards emphasize on robust quality management systems by automotive component manufacturers. These systems promote consistent and controlled manufacturing processes, leading to more reliable and higher-quality components.
- Endurance and Environmental Testing: AEC-Q standards require components to undergo rigorous testing, including environmental stress testing and extended operational life testing. These tests ensure that components can withstand the harsh conditions and long lifespans typical in automotive applications. Components that pass such tests are less likely to malfunction.

- The “process” requirements from the corresponding standard must be integrated in the Organization’s Internal design and development process. For example, standards like AECQ, IATF16949, ISO26262 or SOTIF have requirements on what process or methods should be followed. These should be integrated as part of the regular process followed by that Organization.
- “Technical” requirements stated in these standards must be brought in upfront as a requirement for the corresponding skill area. For e.g., if there is a regulatory requirement relating to the position of Camera, that needs to be brought in as a requirement to the Mechanical team at the start of the program.
