Systematic Derivation of Functional Safety Requirements for Automotive Systems
نویسندگان
چکیده
The released ISO 26262 standard for automotive systems requires breaking down safety goals from the hazard analysis and risk assessment into functional safety requirements in the functional safety concept. It has to be justified that the defined functional safety requirements are suitable to achieve the stated safety goals. In this paper, we present a systematic, structured and model-based method to define functional safety requirements using a given set of safety goals. The rationale for safety goal achievement, the relevant attributes of the functional safety requirements, and their relationships are represented by a UML notation extended with stereotypes. The UML model enables a rigorous validation of several constraints expressed in OCL. We illustrate our method using an example electronic steering column lock system.

متن کاملDeriving Safety Requirements Using Scenarios
Elicitation of requirements for safety critical aeroengine control systems is dependent on the capture of core design intent and the systematic derivation of requirements addressing hazardous deviations from that intent. Derivation of these requirements is inextricably linked to the safety assessment process. Conventional civil aerospace practice (as advocated by guidelines such as ARP4754 and ...

متن کاملAssessing and enhancing functional safety mechanisms for safety-critical software systems
More and more devices of our everyday life are computerized with smart embedded systems and software-intensive electronics. Whenever these pervasive embedded systems interact with the physical world and have the potential to endanger human lives or to cause significant damage, they are considered safety-critical. To avoid any unreasonable risk originating from the failure of such systems, strin...
متن کاملA Systematic Inclusion of Diagnosis Performance in Fault Tree Analysis
Safety is of major concern in many applications such as in automotive systems and aerospace. In these applications it is standard to use fault trees, and a natural question in many modern systems that include sub-systems like diagnosis, fault tolerant control and autonomous functions, is how to include the performance of these algorithms in a fault tree analysis for safety. Many possibilities e...
