Intro to Automotive functional safety( ISO26262)

Explore the meaning of safety and functional safety, distinguish safety from security, and see how ISO 26262 guides safe automotive systems through failures like Piper Alpha and Tesla Autopilot incidents.

Explore how IEC 61508 and ISO 26262 define functional safety for safety related systems in road vehicles, detailing the development process to identify hazards and reduce risks to acceptable levels.

Examine active safety and passive safety, two vehicle safety systems that avoid accidents with anti-lock braking and reduce injury with airbags.

Trace ISO 26262's evolution from 2011 to 2018, compare normative and informative elements, and outline the safety lifecycle from concept to maintenance within functional safety management using the V-model.

Define and document vehicle items in the concept phase of ISO26262, detailing item purpose, functionality, dependencies, and interactions to guide subsequent functional safety activities.

Decide if a vehicle item is new or a modification, perform impact analysis, and initiate the safety lifecycle with a well-defined safety plan and activities within a safety culture.

Learn hazard analysis and risk assessment (HARA) for automotive items, determine ASIL levels from severity, exposure, and controllability, and define safety goals under ISO 26262.

Define functional safety concept and asil decomposition to allocate requirements to architecture elements, aligning with asil levels per ISO 26262, and using a safety controller for the acc output signal.

Explore ISO part 4's system-level safety by linking functional safety concepts to technical safety requirements, including safety analysis methods like FTA. Learn about ASIL testing and CAN bus protection.

Develop hardware-level functional safety requirements in parallel with software, and apply FMEDA to assess hardware from specification, design, implementation, integration, and validation, including single point, probabilistic, and latent fault metrics.

Explore software level product development per ISO 26262, from architecture to verification, and apply FMEA to identify failures, effects, and safety mechanisms. Understand ASIL-based requirements, V-model, and MCDC coverage.

Validate the safety product after development through ISO 26262 part 4 functional safety assessment and documentation, then release for production and plan for operation and service.

Explore ISO 26262-2018, now including part 11 for semiconductors and part 12 for motorcycles, and learn to map functional safety steps across the lifecycle for all road vehicles.
