Functional safety

How safe is safe?

Functional safety

Safety in electronic systems is particularly fond of striking when it fails. The crash of the Boeing A737 Max recently reminded us of the immense importance of functional safety in electronic development.

What applies to the controversial maneuver correction system in the aviation industry also applies, albeit in a figurative sense, to the automotive industry and its increasingly automated assistance systems. However, electronic systems also have increasingly important decisions to make beyond the boundaries of the industry.

Functional safety is gaining in importance

Due to the increasing technical complexity and the automation of technical systems, functional safety is becoming more and more important. The primary objective is to ensure freedom from unacceptable risks - and thus to protect human life. For automotive applications, ISO26262 provides a framework to meet this requirement. This results in an effective supplementation of the development process with standard-compliant safety aspects, which offers many advantages:

  • Security
  • Transparency
  • Traceability
  • Speed
  • Economic efficiency

Functional safety as a future-oriented standard (FuSi)

FuSi, as people familiar with the subject like to abbreviate the area of functional safety, is wrongly regarded as a burdensome or cumbersome additional expense. When applied correctly, functional safety is an integrative enrichment. With a partner who has expertise in safety management, it is easy to make your own functional safety comprehensive and productive. Cognizant Mobility optimizes the safety lifecycle for individual needs and offers a rich repertoire for this purpose:

  • Best Practices
  • Templates
  • Analysis Tools
  • Method and Process Modules
  • State-of-the-Art security for your development

In A Nutshell

  • Product Safety
  • Functional Safety Management
  • Functional Safety Consulting
  • Safety Analysis
  • IEC 61508 und ISO 26262

The more complex systems become, and the more decisions are made by them, the higher the importance of functional safety - not least to fully satisfy legal requirements. In this context, the consideration of the overall system is also becoming increasingly important. In the future, not only electrical/electronic components will be included, but also interfaces such as mechanical or hydraulic scopes, which in one form or another are involved in decisions making and execution of functions. Safety of the intended Function" (SOTIF), which is based precisely on this approach, is still in its infancy, but is increasingly establishing itself as the standard. Cognizant Mobility is the competent partner for successfully implementing future projects.
