This proposal for ADS Regulation version 2 addresses remote support for automated driving systems. ECE/TRANS/WP.29/2026/137 contains 19 instances of remote references across definitions, requirements, and annexes, with only remote termination defined. The proposal requests UNECE GRVA to introduce and define different types of remote support, clarify terminology distinctions between remote monitoring, remote assistance, and remote intervention, and articulate which aspects of remote support the regulation covers. The submitter offers to provide definitions developed with ISO 26361 for consideration at the July 2026 ADS IWG meeting.
Proposal to revise Annex 3, item 2 regarding “ADS failure to achieve a mitigated risk condition when necessary.” The revised text maintains the four bullet points describing when such occurrence is expected to be reported when an MRC is required. The rationale states the regulatory text does not require reporting when an MRC is achieved but in an unsafe stop location, which is not defined in the regulation, nor when an MRC is achieved but conflicts occur during the MRC.
Proposal to clarify MRC for ADSF-2 in para. 6.1.5.4.1. The revised text corrects the assertion that ADSF-2 features can meet a lower standard for MRC because of fallback user presence in ADSF-1. It clarifies that ADSF-2 features do not include an ADS fallback response requiring a fallback user, though such features may be present in vehicles with human users. Both ADSF-1 and ADSF-2 features must aim to bring the ADS vehicle to a stop in a safe location complying with traffic rules following ODD exit.
Proposal to update the explanation on reportable occurrences in Annex 1 (GTR) and 3 (UNR). The revision refines language in the requirement describing the manufacturer’s Safety Management System by removing “expected” to avoid implying obligation and clarifying the link between occurrence monitoring, reporting, analysis, system updates, improvements, and continuous improvement processes.
Proposal to clarify EDR provision in Annex on thresholds. For vehicle categories M2, M3, N2, and N3, the revised text clarifies that UN Regulation No. 169 does not include a representative delta V threshold. The manufacturer could determine their own delta-V trigger for a critical occurrence, including one based on a subset of EDR triggers, with no obligation to do so.
This paper is to inform relevant GRs of the ongoing activities within the CLIV informal group and the potential influence on the work under the responsibilities of the GRs. CLIV is in Phase 2 developing a new UN Regulation on Children Left in Vehicles for vehicle categories M1, M2, M3 and N1. The draft regulation includes requirements for visual and audible external warnings upon detecting a CLIV event. The IWG prioritises development for buses first, then light vehicles. The draft regulation aims to mitigate risk of serious or fatal injuries to children left in vehicles. Upon detecting a CLIV event, visual and audible external warnings will be generated using an SOS morse code pattern to distinguish from existing warnings.
The revised text adds ISO 21448, GB/T 34590 Road vehicles-Functional safety, and GB/T 43267 Road vehicles – Safety of the intended functionality to the original reference standards ISO 26262-2/8:2028 and ISO 9001 2015. GB/T 34590 is an important reference for functional safety in China and ISO 21448 and GB/T 43267 are important references for SOTIF.
The change request seeks clarification that “real-time” operational and tactical functions of the DDT, particularly “sensing and perception” and “planning and decision”, could be achieved through real-time sensor inputs alone or through integration of sensor inputs with other contextual information such as map-based data, to aid technical inspectors during testing and assessment of ADS systems.
Mr. Loccufier, Chairman of the Informal Working Group, opened the session welcoming all the participants.
