Requirements

This course is about ISO 26262-4: Product development at the system level. All relevant clauses of this part of ISO 26262 are explained in the course. The following clauses are considered:

  • Clause 6: Technical safety concept
  • Clause 7: System architectural design
  • Clause 8: System and item integration and verification
  • Clause 9: Safety validation

 

The following aspects are considered in Clause 6: Technical safety concept:

  • The ISO 26262 V-model for the development phase
  • Definition of the term “system”
  • Characteristics and attributes of technical safety requirements

The following aspects are considered in Clause 7: System architectural design:

  • Relevant aspects for derivation of the system architectural design from the preliminary architectural design
  • Safety analyses according to ISO 26262
  • Explanation of the method fault tree analysis (FTA) with an example
  • Explanation of the method failure mode and effects analysis (FMEA) according to the VDA/AIAG handbook (7 Steps)

The following aspects are considered in Clause 8: System and item integration and testing:

  • Relevant integration levels
  • Test objectives according to ISO 26262
  • Test methods

The following aspects are considered in Clause 9: Safety validation:

  • What is the difference between verification and validation?

 

The course includes an exercise for clause 6 and clause 7.

In the exercises you will learn step by step how to develop the technical safety concept for an electric vehicle and the safety goal “Avoid an unintented acceleration”.

A possible solution for the exercise is presented in a video.
