A number of components of a car are safety-critical like Electronic Steering System, Anti-lock Braking System, Air-bags, electronic stability control, and more. By safety-critical, we mean that the failure of these components can risk the driver or the passengers’ life. ISO26262 is a standard that defines a framework to implement safety practices during the design, development, and testing of all the critical electrical and electronic components of a road vehicle. This standard has been derived from IEC61508. ISO26262 standard comprises a set of steps that regulate the product lifecycle at the software and the hardware level. ISO26262 provides an extensive set of recommendations for automotive product development, right from the conceptualization to the decommissioning stage. With the introduction of electronic control units to automotive vehicles, system complexity has increased. With this change in complexity, new standards have been created to ensure safety at the system level for these vehicles. Furthermore, vehicles have become increasingly complex with the push for electrification of automotive vehicles, which has resulted in the creation of hybrid electric and battery electric vehicles. ASIL (Automotive Safety Integrity Level) is the notation for software or hardware component that signifies its safety-criticality. ASIL A, ASIL B, ASIL C, and ASIL D. ASIL A indicates the least critical level and D indicates the most critical level. There are three factors that determine the ASIL of software or hardware- the probability of exposure, controllability by the driver, and the severity of the outcome if a fault occurs. ASIL A is almost equivalent to QM level, therefore, ASIL B is usually the minimum requirement, in order to make your product compliant with ISO 26262 Standard for Functional Safety. ASIL is determined at the beginning of the automotive software development with the help of HARA. However, it can be done post the development also but is not recommended. Based on the ASIL rating, safety processes and testing regulations are followed- strictest for D and flexible for A.
