Proposal to establish a Task Force on Swappable Batteries (TFSB) under GRPE. The task force will review WP.29 regulations and international standards to identify technical requirements for swappable-battery vehicles, focusing on commercial vehicles. It will define vehicle types, clarify vehicle type approval processes, and develop guidance documents. The task force will coordinate with other working groups including GRSP and GRVA, with deliverables expected by October 2027.

Proposal to add retrieval of DSSAD time-stamp data elements recorded for at least the last 30 seconds before the last setting of the event flag “Event Data Recorder (EDR) trigger input” alongside EDR data through the same interface, add provisions for retrieval when no such event occurs within the last 30 seconds, add provisions to replace date and time with relative time information when required by national or regional law, and add detected collision by Automated Driving System as an EDR trigger for UN R160 and UN R169.

Proposal to amend Annex 4 – Data elements and format, Table 1, modifying Advanced driver distraction warning (ADDW) data elements to record status and time since warning issued instead of number of warnings and time elapsed since last warning, modifying Driver control assistance system (DCAS) driver monitoring system data elements to record time since disengagement warning issued and warning type instead of number of hands-on requests, eyes-on requests, direct control alerts, and time elapsed since last warning, and adding Driver drowsiness and attention warning (DDAW) status and time since warning issued data elements while removing number of warnings and time elapsed since last warning, with ADDW and DDAW elements listed up to five times for most recent warnings and DCAS warning type listed up to fifteen times for most recent warnings on current trip.

The 19th Automated Driving Systems session in Shanghai (February 2026) involved approximately 90 participants from multiple countries and organizations. Key outcomes included adoption of amendments to UNR and GTR on ADS, addressing EDR/DSSAD definitions and recording intervals, and reviewing Guidance and Interpretation Document sections covering introduction, DDT performance, audit, user interaction, approval, FADS, safety case, testing, and ISMR. Outstanding items for resolution include remote assistance prioritization and future work program definition. Amendments will be submitted to WP.29 in June 2026. Future meetings scheduled for April-May in Bangkok and July in Brussels.

Proposal to amend the 03 Series of Amendments to UN Regulation No. 160 (Event Data Recorder). The document modifies definitions, recording conditions, and data elements for EDRs. Key changes include: renumbering paragraph 2.2 to 2.25; amending definitions for end of event time, engine throttle, non-volatile memory, and volatile memory; adding new definitions for rollover protection systems, advanced emergency braking systems, and driver assistance systems; clarifying trigger conditions for recording planar, rollover, and vulnerable road user events; specifying time zero establishment; adding transitional provisions; and expanding Annex 4 data elements table to include pre-event synchronization timer, trigger activated status, acceleration control for pedal error, driver distraction warning, driver drowsiness warning, blind spot monitoring, turn signal status, and emergency stop signal status.
