Control systems safety evaluation and reliability pdf

  • What is safety reliability?

    Safety is achieved through the use of reliable structures, components, systems and procedures.
    Reliability is the probability that a system or component will perform its intended function for a prescribed time and under stipulated environmental conditions..

  • As mentioned before, reliable control is a design. theory for realizing safety function in redundancy existing in a control system without urgent de- tection of failures.
    This is a contribution to fault- tolerance technology from control system design.
  • Reliability engineering is an engineering discipline for applying scientific know-how to a component, product, plant, or process in order to ensure that it performs its intended function, without failure, for the required time duration in a specified environment.

Should Software Reliability Metrics be used for software safety assessments?

DO-178C also states that software reliability metrics should not be used for software safety assessments

This section discussed the safety analysis methods listed in ISO 26262

What is electronics reliability research?

The electronics reliability research comprises methods and standards within and outside the automotive industry for assessing, identifying and mitigating potential and new hazards that may arise from the increasing use of electronics and electronic control systems in the design of modern automobiles

What is the most relevant automotive electronic control system safety standard?

ISO 26262 is the most relevant automotive electronic control system safety standard within the context of this study

This study also chose to review the five additional standards listed above because the ISO 26262 committee and industry practitioners frequently cited them in various discussions and research papers
