A Comprehensive Approach for Functional Safety of Advanced Driver Assistance Features

Inhalt:
Advanced Driver Assistance features like autonomous-emergency-braking (AEB), traffic-jam-assist (TJA) or lane-keepassist (LKA) combine ‘traditional’ functional safety with input systems (e.g. camera) where algorithm-based situationinterpretation and reasoning is contained. ISO 26262 traditionally defines measures for a structured design and analysis approach, hardware metrics and validation activities on component, subsystem and vehicle level. It covers functional safety of E/E systems. However this approach does not comprehend the full aspect of Advanced Driver Assistance features where interpretation of the surrounding through algorithm based reasoning provides input to safety critical decisions. What is required is a comprehensive approach including the “Safety of the Intended Function”, which covers additionally real-word performance in different driving situations.
