The document discusses functional safety in the automotive industry according to ISO 26262. It provides an overview of ISO 26262 and its requirements for automotive safety including an automotive safety integrity level (ASIL) to measure risk reduction. The presentation also discusses three case studies involving the certification of products, processes, and software tools according to ISO 26262.
