Practical Implementation of Mixed-ASIL Systems - a Certified Operating System Simplifies the Development of Safety-Related Software
The ISO 26262 standard describes a recognized and standardized process for developing safety-related ECUs in the automotive field. However, only parts of the software in these ECUs are safety-related. The goal is to restrict the additional, intensive development efforts for these safety-related components. It is possible to set up an ISO-conformant mixed-ASIL system, which may contain both ASIL functions and functions without qualification, using an advanced AUTOSAR operating system and two other basic software modules.
