Upon successful completion of this training workshop, you will be able to:

  • Summarize the similarities and differences between FMEDA and FTA
  • Perform comprehensive software safety analysis
  • Analyze confidence levels for failure rate data
  • Understand advanced topics in fault detection, mitigation and control
  • Become familiar with the multi-point fault detection interval and how it’s used
  • Integrate the metrics for safety validation within your team’s framework
  • Document the vehicle-level integration of supplier safety analysis
Contents

This two-day advanced training for automotive safety analysis of failure modes and effects analysis (FMEA), failure modes and effects diagnostics analysis (FMEDA), and fault tree analysis (FTA) will address the requirements of ISO 26262:2018, the standard for road vehicles — functional safety, with detailed examples from Parts 4, 5 and 6.

The course begins with an introduction to FMEA basics, moving onto unique requirements for safety FMEA and how the FMEA for functional safety concept (FSC) and technical safety concept (TSC) are developed. The training focuses on ISO 26262, Parts 4, 5 and 6, with specific experience-based guidance on performing effective software safety analyses, including FMEA and dependent failure analysis (DFA).

Several core concepts include qualitative versus quantitative analysis of the FMEDA, failures in time (FIT) rate calculations and catalogs, and calculating the ISO 26262 hardware random failure metrics with FMEDA. The second day of the training touches on FTA basics with detailed guidance on the similarities and differences between the FMEA and FTA integration metrics for safety validation.

This training also includes a discussion of the best practices and requirements from ISO 26262:2018-8, Clause 9-Verification, and ISO 26262:2018-9, Clause 7-Analysis of Dependent Failures and Clause 8-Safety Analyses.
