Abstract
The standard ISO 26262 plays a key role in defining functional safety of all electrical and electronic systems which are supposed to be used for automotive applications. Distribution of safety related activities according to ISO 26262 among various participants in the automotive supply chain is a challenging task. These activities include item definition, hazard analysis and risk assessment (HARA), functional and technical safety concept etc. Being the most essential step in the development flow, usage of an efficient, accurate and practical approach is necessary for performing HARA especially during development of any electronic control unit (ECU), hardware or software intellectual properties as they are developed as safety element out of context (SEooC). In this paper, a novel safety life cycle is proposed for SEooC development to overcome the problematic aspects of existing safety processes. A novel approach for generic hazard analysis and risk assessment (GHARA) and its optimization is also proposed which satisfies the requirement of the proposed safety life cycle.
