Efficient Identification of Safety Goals in the Automotive E/E Domain

This paper addresses the problem of how to identify all safety goals for an item in the automotive E/E domain. The paper gives a background on the problem of hazard analysis and risk assessment in general, and for the automotive domain in particular. A key factor for success is to identify all the relevant hazardous events, which task constitutes a paradox. Either the specification of the possible driving situations and the system hazards are done too general and abstract implying a too conservative analysis, or done too detailed and specific ending up with an almost infinite list of hazardous events to consider. This paper addresses this paradox by the formulation of a number of rules enabling to reduce the potentially infinite set of candidates of hazardous events to a limited number, still sufficient to cover all safety goals. Besides that it enables solving the paradox of becoming both detailed and limited, it also can be used as a tool for reviewing the completeness of a set of safety goals.
