Preliminary Hazard Analysis Generation Integrated with Operational Architecture - Application to Automobile

Abstract. We are witnessing evolution of standards (as the functional safety one) and increas-ing of complexity. This implies to perform safety studies efficiently and earlier in the context of Model-Based System Engineering. So, in this article, we will propose an evolution of the Pre-liminary Hazard Analysis (PHA) method in order to comply with the overall safety require-ments in the automotive domain. To demonstrate its usefulness, we apply this method to an industrial case which concerns the hazard analysis of unintended acceleration of a vehicle

Preliminary hazard analysis generation integrated with operational architecture - application to automobile

International audienceWe are witnessing evolution of standards (as the functional safety one) and increasing of complexity. This implies to perform safety studies efficiently and earlier in the context of Model-Based System Engineering. So, in this article, we will propose an evolution of the Preliminary Hazard Analysis (PHA) method in order to comply with the overall safety requirements in the automotive domain. To demonstrate its usefulness, we apply this method to an industrial case which concerns the hazard analysis of unintended acceleration of a vehicle

Definition and verification of functional safety concepts for the definition of safe logical architectures

International audienceEvolving customer expectations, particularly growing concerns for safety, and the development of autonomous vehicles imply the development of many interconnected functions. To meet the expectations of system performances and to respect safety standards like ISO 26262, systems engineering and safety analysis have to be better integrated. In this paper we propose a conceptual framework and a method to define and verify the functional view of the logical architectures from a safety point of view

Towards a safe systems engineering

International audienceFaced with the increasing complexity of systems, model-based system engineering relies on SysML, one of the recognized languages for systems modeling. In the case of the automotive industry, the introduction of model-based systems engineering in the design process is considered as an efficient way to improve design performance and to master new regulations such as ISO 26262 (ISO 2009) concerning functional safety of automotive systems. Although research work exists on model-based safety assessments (see Cressent et al. 2012; Belmonte and Soubiran 2012), there remains a lack of an approach on integrating system engineering and safety analysis, two domains handling their own concepts, models, and methods. In this short article, we are presenting two types of approaches
