Elektrobit (EB) is among the first suppliers to deliver an ASIL D certified AUTOSAR operating system and the only one certified for two safety standards.
Elektrobit achieved its Functional Safety certification by the assessment agency exida Certification SA for the EB tresos Safety OS. Exida confirmed that the software is capable for use in Automotive Safety Integrity Level D (ASIL D) applications such as electrical power steering. Additionally, the OS is certified for Safety Integrity Level 3 (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.
Functional safety is getting more and more important for today’s automotive ECUs. EB therefore invested a great deal of time and effort in the development of an innovative operating system for AUTOSAR ECUs that meets the highest security standards. The EB tresos Safety OS protects itself against possible errors caused by other software running on the ECU. This allows a safe execution environment for safety critical functions independent from non-safety software. The EB tresos Safety OS is seamless integrated into the EB AUTOSAR solutions using EB tresos Studio configuration tool.
To provide a safe execution environment EB took proven concepts such as the microkernel and system call approach used in the aerospace and industrial market and transferred these to the AUTOSAR world. Beside a safe context switch, the EB tresos Safety OS also protects safety relevant functions for AUTOSAR systems like task scheduling, event handling and locking mechanisms. This robust and protected operating system enables the development of ECUs up to the highest safety level. The safe partitioning of ECU software reduces the effort for safety analysis and speed up the development of safety related ECUs.
The assessment by exida checked the EB tresos Safety OS with respect to software architecture and design, processes and documentation. After an extensive assessment exida confirmed that the audited development process as well as the software developed for the EB tresos Safety OS microkernel comply with the relevant safety management and design requirements of ISO26262 ASIL D and IEC 61508 SIL 3.
“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,” said Rainer Faller, principal partner of exida. “The assessment was greatly supported by the high level of competence of the Elektrobit development team.”
Jochen Schoof, vice president for ECU Software and Tools at EB added, “We are proud to be the first company using such an innovative and certified technology in AUTOSAR projects. This certificate is the result of many years of research activities at EB and demonstrates our leading position in the AUTOSAR space.”
EB tresos Safety OS already is in use in several AUTOSAR mass production projects of major German car manufacturers and automotive suppliers. It also is already available for safety microcontrollers from Freescale, STM, Infineon, Texas Instruments and Renesas.
