Functional Safety and AUTOSAR

Functional Safety is becoming more and more important for today’s automotive industry. Therefore, EB Automotive took the next step to enable widely available AUTOSAR electronic control units (ECUs), by helping customers develop and integrate applications into safety related systems in accordance with the ISO26262 standard up to the highest safety classification level, ASIL D. Additionally, our solutions conform with the IEC61508 and range up to the SIL 3 for non-automotive use.

EB Automotive’s concepts and mechanisms are approved for mass production and seamlessly integrate into the EB tresos product line.

Functional Safety Solutions by EB Automotive offer:

  • Best-in-class solutions for ISO26262 / IEC61508 requirements
  • Complete freedom from interference
  • Extensive multi-core expertise
  • Ready for mass production and already in use at several car manufacturers

Example configuration: EB tresos Safety products allow a very flexible partitioning depending on the customer project needs.

Certified Safety Operating System

EB Automotive earned a Functional Safety certification by the assessment agency exida for the EB tresos Safety OS.

Exida confirmed EB Automotive software capability for use in ASIL D applications such as electrical power steering. Additionally, the Operating System is certified for SIL 3 used in non-automotive projects. ASIL D and SIL 3 rank among the highest security levels for functional safety according to the ISO26262 / IEC 61508 specifications for electric and electronic components.

Statement by Rainer Faller, Principal Partner of exida:

“During the independent certification for functional safety to ISO 26262 ASIL D performed by exida, it became clear that the EB tresos Safety OS microkernel has been developed from the ground up for safety applications. The assessment was greatly supported by the high level of competence of the Elektrobit development team”.
