The Determination of Functional Safety Concept coupled with the definition of Logical Architecture: a framework of analysis from the automotive industry

In the nineties the growing integration of electronic components in mass products led to the introduction of systems engineering methods in the design offices. In the automotive industry this deployment has been accelerated due to the need for the reduction of polluting emissions and for safety concerns. Recently the introduction of safety standards such as ISO 26262 and the design of connected and autonomous vehicles required the development of new system modeling approaches, and particularly, model-based safety analysis methods (MBSA). In this article, we explain how Functional Safety Concept can be determined jointly with the definition of the logical architecture. This will be based on failure propagation mechanisms. This method is applied on an automotive case study. (C) 2017, IFAC (International Federation of Automatic Control) Hosting by Elsevier Ltd. All rights reserved.
