Synchronisation of an Automotive Multi-concern Development Process

Abstract

Standardisation has a primary role in establishing common ground and providing technical guidance on best practices. However, as the methods for Autonomous Driving Systems design, validation and assurance are still in their initial stages, and several of the standards are under development or have been recently published, an established practice for how to work with several complementary standards simultaneously is still lacking. To bridge this gap, we present a unified chart describing the processes, artefacts, and activities for three road vehicle standards addressing different concerns: ISO 26262 -functional safety, ISO 21448 -safety of the intended functionality, and ISO 21434 -cybersecurity engineering. In particular, the need to ensure alignment between the concerns is addressed with a synchronisation structure regarding content and timing.

Software Design Trends Supporting Multiconcern Assurance

“…Advances toward the developing approaches that ensure that changes in a system do not trigger long and costly certification processes and that support incremental assurance have been developed. [8][9][10] Tools for Supporting Automated Analyses at the Design Phase…”
