Proposal to establish an informal working group on Exchange of scenario-relevant information (ESRI) as a subsidiary body of GRVA to develop procedures facilitating the sharing of DDT-relevant building blocks and knowledge from performance analyses and incident investigations, to structure such information to support scenario development and use, to propose means for managing and publicly sharing information in accordance with WP.29 procedures, and to provide recommendations for application and management, with outcomes to be presented within two years from approval to form the IWG by GRVA.
Proposal to amend para. 5.6.1.2.7. to increase the maximum RCP operating range from 6 m to 15 m. UN R79 currently limits the maximum RCP operating range to 6 m, resulting in effective usable range of 2 or 3 m due to radio wave-based ranging inaccuracy. A 15-meter range would enhance RCP function usefulness and safety, reducing driver movement and blind areas. RCP systems with extended ranges have been used in large markets without identified safety threats. The amendment is proposed as a supplement to the 03 and 04 series of amendments to UN R79.
Proposal to amend ECE/TRANS/WP.29/2026/139 to modify para. 4.2.2.3.8.1. subparagraph (b) to state gaze directed to the driving task relevant area, amend para. 6.3.2.2.3. to replace approval authority with assessment, amend Annex 5 table 5 rows 1 and 2 column 7 to specify fallback to a mitigated risk condition and set deceleration at 4 m/s², amend Annex 6 para. 5.3.1. to remove brackets, amend Annex 6 para. 5.3.2. table to insert Mandatory in row 1 column 2 and specify recording interval of -7 to +7 seconds for visual images, and remove the bracket after table 5.3.2.
AC.1 adopted all amendments proposals to UN Regulations submitted by GRVA. AC.2 supported a swap between the GRVA session in October 2026 and the WP.1 session in September 2026 and discussed possibilities to change working methods. AC.3 welcomed progress on development of a new UN GTR and a new UN Regulation on ADS and noted the status report on ACPE activities. WP.29/1188 contains further details.
The agenda includes items on artificial intelligence in automotive, automated and connected vehicles including ADS, workshops, UN Regulation No. 157, UN Regulations Nos. 155 and 156, advanced driver assistance systems, steering equipment, emergency lane keeping systems, advanced emergency braking and blind spot information systems, electronic stability control, motorcycle braking, and UN Regulation No. 90. Additional agenda items address Revision 3 to the 1958 Agreement, climate change mitigation strategy, meeting arrangements, and programme of work.
The session is scheduled for May 19, 2026, from 05:30 to 08:00 EDT. The agenda includes discussion of UN GTR 22 and UN GTR 25 regulatory topics covering conditioning cycles, SOCE readiness monitor, MPRs, SOCR, mutual recognition, FCEVs, highly integrated systems, efficient test methods, OICA comments, MPRs and energy throughput, normal usage indices, Part C virtual distance verification, Annex 2 alternative test method, and battery replacement provisions. UN GTR 25 Amendment 2 must be submitted to March 2027 GRPE by December 2026 deadline.
The Informal Working Group on EV/HFCV Retrofit Systems held its eighth meeting on 21 April 2026. The group discussed cybersecurity principles, requiring retrofitted vehicles not to reduce safety or cybersecurity performance compared with UN R155 requirements, with differentiated approaches for base vehicles approved or not approved to UN R155. Braking compliance, EMC testing references, and UN draft regulation changes including renaming to “vehicles intended to be transformed into pure electric vehicles” and introducing Electric Powertrain Retrofit Systems definitions were addressed. PTI-related aspects and the need for written contributions were highlighted before providing the draft regulation to GRPE in October.
