Safety Assessment of Distributed Automotive Software System Model with Design for Traceability

Authors : S. Ravikumar, S. Chandrasekaran and S. Ramesh

Abstract: The objective of the research work is to propose a safety assessment model for an automotive software design as an interacting distributed software component towards traceability. The existing challenges in the automotive software are the composability of the distributed design components and the traceability of the fully assembled or partially assembled design software components. The safety of the composable design does not only depend on the individual software component behavior but also depends on the traceability of each of them in every possible level in both the directions. In such distributed design environment, the software design components can be classified into three types as influential, in-connection and in-absentia types. The proposed research explores a formal approach for the Safety Assessment Logic (SAL) with prevailing the Safety Integrity Levels (SIL). The set of distributed parameters which may cause the risk are studied using a Safety Assessment, Design document (SAD). The distributed SADs are reported to a central server as Document as a Service (DaaS) for carrying out the safe transactions and alert messages across the system. Safety components from each category are considered like air-bag release time, anti-lock braking system and parking distance parameters are tested under various environment conditions.
