What is Functional Safety in Automotive?
Automotive functional safety implements protective measures to eliminate hazards caused by failure or unintended behavior of a vehicle-level system. The ISO 26262 standard offers automotive manufacturers and their suppliers a comprehensive set of guidelines to guarantee the attainment of functional safety throughout every stage of product design. It sets out criteria for the safety-critical functions of a system, as well as the processes, techniques, and tools utilized during the development phase. This standard is instrumental in guaranteeing that the vehicle lifecycle maintains and upholds adequate safety levels.
Our Automotive experts are well-versed with ISO 26262 and follow a systematic approach to achieve functional safety in automotive systems. From hazard analysis and risk assessment to defining safety goals and requirements, our process is meticulous and thorough. Our team of expert engineers ensures that safety mechanisms, redundancies, and fail-safe features are integrated into the system architecture. Throughout the development process, we conduct rigorous verification and validation activities to guarantee that safety requirements are met and that the system operates as intended.
What is ASIL?
ASIL refers to Automotive Safety Integrity Level. It is a risk classification system defined by the ISO 26262 standard for the functional safety of road vehicles.
The ASIL Level is related to the prevention or mitigation of the associated hazards in order to avoid unreasonable risk in using any automotive systems. There are four ASILs identified by ISO 26262―A, B, C, and D. ASIL A represents the lowest degree and ASIL D represents the highest degree of automotive hazard.
While compliance with ISO 26262 is not mandatory, it is the state-of-the-art practice within the industry, and ASIL is a key piece of the standard. ASIL determines how rigorous the process for developing a product should be based on the risk of that product harming a person if it fails. By doing a full safety assessment of each component, module, or system based on a variety of factors, teams can come to a reasonable expectation of risks and outcomes in the event of failure and implement mitigation efforts to reduce risks.
How ASIL Levels determined?
ASILs are established by performing hazard analysis and risk assessment. For each electronic component in a vehicle, engineers measure three specific variables:
- Severity (the type of injuries to the driver and passengers)
- Exposure (how often the vehicle is exposed to the hazard)
- Controllability (how much the driver can do to prevent the injury)
