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.

Proposal to amend UN R169 by inserting definitions for non-volatile and volatile memory, and modifying the Last Stop trigger criteria. The amendment allows threshold criterion (a) data to be written to volatile memory only, transferring to non-volatile memory when other triggers occur or the master control switch deactivates. This reduces memory wear in vehicles with frequent stops exceeding 20 seconds.

Proposal to introduce provisions for rollover protection systems, advanced emergency braking systems, vulnerable road user secondary safety systems, and driver assistance systems. Amendments clarify triggering conditions for event recording and data locking, expand data elements to capture vulnerable road user collisions and advanced safety system interventions, increase sample rates for improved data granularity, and add transitional provisions for type-approval acceptance timelines.

Proposal to amend UN R158 to include category O vehicles (trailers) within the scope of regulations for devices enabling driver awareness of vulnerable road users during reversing. The amendment aims to reduce safety risks to vulnerable road users when category O vehicles reverse. Amendments modify title, paragraphs 1.1, 1.2, 1.4, 12.3, 12.4, and Annex 4, and introduce transitional provisions starting from September 2028. Justification includes casualty data showing seven fatalities and 15 serious injuries over 10 years from vehicles towing trailers reversing into vulnerable road users, plus a coroner’s recommendation for reversing cameras on all vehicles.

Five documents propose amendments to UN R46 series 02-07 to align requirements with UN R26 and UN R61, particularly regarding soft parts of camera monitoring systems and mirrors based on Shore A hardness. The 05 series introduced alignment requirements; harmonization is proposed for earlier series with existing approvals.
