Challenges

Security standards for critical systems

Ensuring that all safety-critical systems meet the required safety standards.

Addressing the complex landscape of functional safety in an ASIL D energy management system involved overcoming numerous challenges, including close collaboration with all technical areas and management, reviewing work products across various domains—from system to testing—and ensuring that functional and technical safety concepts align with ISO 26262.

Solution Implemented

Safety-Relevant Product Analysis and Evaluation

Safety-Relevant Product Analysis and Evaluation

Coordination, analysis, and evaluation of safety-related work products.

Our solution involved analyzing and evaluating specific safety concepts, safety analyses, and safety requirements for system, software, and hardware development.

To ensure that work products met the required standards and stakeholder requirements, close collaboration with engineers and managers was essential. Confirmation reviews and safety assessments of work products were conducted. Throughout the process—from developing and implementing functional and technical safety concepts to designing and defining requirements (system, software, hardware, testing)—expert advice and support were provided.

Understanding Concept Design:

  • Understanding the functions and their role within the overall platform.
  • Holistic evaluation of the ASIL D energy management system concerning functional safety according to ISO 26262.
  • Analysis of the existing technical and functional safety concepts.

Functional Safety Management:

  • Participation and support as part of the moderation team for FMEA (System, Hardware, Software).
  • Participation and support as part of the moderation team for FTA (Fault Tree Analysis).
  • Participation and support as part of the moderation team for DFA (Dependent Fault Analysis).
  • Reviews and inspections of work products such as requirements, architecture, TSC, FSC.
  • Processing of CR (Change Requests).
  • General safety management, including task planning and maintenance of the safety plan concerning assigned tasks.
  • Analysis and evaluation of specific safety concepts, safety analyses, and safety requirements for system, software, and hardware development and testing.
  • Collecting evidence to meet ISO 26262 requirements from the relevant areas.
  • Summarizing evaluation results in a clear, documented form.

Results

Improving the Quality of Safety Analyses and Concepts

Our collaboration significantly improved the quality and completeness of requirements, architecture, and safety analyses, as well as the technical and functional safety concepts. Traceability between different work products was ensured throughout. At the end of the project, a TÜV assessment was conducted with very good results.

Our collaboration led to the successful completion of the project, culminating in a TÜV assessment with excellent results.
