The introduction of drive-by-wire capabilities as well as autonomous driving impose in automotive industry the need for vehicle systems to remain operational even in case of critical failures. This so-called fail-operational behavior or in terms of ISO26262 the safety-related availability are important to reach a safe state. We will investigate the challenges associated with the transition from traditional fail-safe approaches and explore effective solutions for key sensor elements in drive-by-wire systems and radar sensors used in autonomous driving. The session will include an analysis of the requirements from Functional Safety standards, particularly ISO 26262, and strategies for achieving compliance. Emphasis will be placed on the importance of redundancy and the justification for ensuring sufficient independence among system components or even within a system component. This talk aims to provide a comprehensive understanding of the necessary concepts and practices for ensuring safety-related availability in modern automotive technology. In this session, you will:

• Get a better understanding of requirements from the perspective of functional safety for fail-operational systems in AVs
• Learn about the challenges in developing fail-operational systems and system elements
• Explore strategies for maintaining critical vehicle control functions during system failures for safe operation
