Imagine an emergency braking system that malfunctions at the wrong moment. Functional safety standards like ISO 26262 prevent such catastrophic outcomes. ISO 26262 saves lives by ensuring systems like ADAS, airbags, and emergency braking operate reliably, even under fault conditions.

Key Components of ISO 26262:
✅ 𝐀𝐒𝐈𝐋 (𝐀𝐮𝐭𝐨𝐦𝐨𝐭𝐢𝐯𝐞 𝐒𝐚𝐟𝐞𝐭𝐲 𝐈𝐧𝐭𝐞𝐠𝐫𝐢𝐭𝐲 𝐋𝐞𝐯𝐞𝐥): Prioritizing safety from ASIL A (low) to ASIL D (critical).
✅ 𝐇𝐚𝐳𝐚𝐫𝐝 𝐀𝐧𝐚𝐥𝐲𝐬𝐢𝐬 & 𝐑𝐢𝐬𝐤 𝐀𝐬𝐬𝐞𝐬𝐬𝐦𝐞𝐧𝐭 (𝐇𝐀𝐑𝐀): Identifying hazards and reducing their risks.
✅ 𝐕-𝐌𝐨𝐝𝐞𝐥 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐦𝐞𝐧𝐭 𝐀𝐩𝐩𝐫𝐨𝐚𝐜𝐡: Ensuring rigorous validation and verification.

In today’s vehicles, safety-critical systems like airbags, lane-keeping assist, and emergency braking depend on ISO 26262 to function flawlessly, even when faults occur. Thus ISO 26262 standard plays important role in Functional safety.
