In Part II of our six-part automotive series, our experts discuss how to ensure functional safety compliance using Jama Connect for Automotive. If you’re new to our Automotive Development blog series, you may want to go back and read Part I and the Series Intro.
While safety has long been an important aspect of developing automotive systems, traditional safety considerations have largely involved mechanical systems. The modern automobiles, however, are increasingly relying on electronic systems and significant amounts of software. This increase in electronics in vehicles brings in new considerations when it comes to functional safety compliance.
Functional Safety Compliance: ISO 26262
The standard that is concerned with the functional safety of electronic systems is ISO 26262. ISO 26262 is actually a series of standards that provides a framework for developing both electronic hardware and software systems where functional safety must be achieved. The standard describes a process for identifying risks in a system and provides guidance for mitigating those risk. The guidance is provided in the form of requirements and processes that are understood by the industry as the current state of the art for achieving functional safety.
A major component of ISO 26262 is a robust series of processes for requirements management and traceability. The processes require that organizations develop safety goals, translate those into functional requirements, technical requirements, and eventually both hardware and software requirements as appropriate for the system. The system must then be fully verified against all requirements and specifications. Critically, the processes require that traceability between the requirements, specifications, and verification activities be maintained and all documentation carefully reviewed.
