This document provides recommendations for DSSAD, a vehicle capability that monitors Automated Driving System (ADS) performance. It defines key terms including ADS, Dynamic Driving Task (DDT), Operational Design Domain (ODD), and Mitigated Risk Condition (MRC). The document specifies requirements for data storage, security, format, and accessibility. DSSAD must record time-stamped events such as feature activation/deactivation, ODD exits, and fallback responses, plus time-series data during triggering events like collisions, including vehicle dynamics and sensor information.
