Model-Based Computer-Aided Monitoring for ISO26262 Compliant Systems

Abstract

To deal with the increasing complexity of todays technology, several domains have defined regulatory framework and guidelines conveying information that the industry sectors should deal with in order to develop sound systems. In the automotive industry, the ISO26262 standard provides recommendations for system development in various phases and activities, aiming to address and reduce the risks associated to poor or flawed designs. However, the recommendations are defined into several volumes integrating a variety of graphical, tabular and other notation elements. This complex structure makes the standard difficult to adopt in industrial practice while manufacturers, regulators, etc. need to have a clear understanding of its content. To address this issue, we are developing in an ongoing project a tool aiming at supporting the stakeholders involved in the product development cycle of an automotive product in accordance with the ISO26262 recommendations. The framework proposes three main artefacts: (1) a structured model of the ISO26262 standard; (2) a guidance tool which document the ISO26262 lifecycle and interactively guide the user during the product development; (3) an user model template that helps gather through the product development the different constituents needed for the definition of a safety case. The potential benefits of the tool is to facilitate the comprehension, navigation and requirements fulfillment of the ISO26262 standard by the stakeholders involved in an automotive product development. This paper provides details related to the approach and implementation of the framework.
