Status report on research activities of the Informal Working Group on ACPE GTR. Canada is conducting ongoing tests with three vehicles examining accelerator application rates, distances to obstacles, and false-positive interventions. The United Kingdom plans to contribute information from Transport London research. South Korea is preparing presentations on documented cases with 10Hz EDR data and KNCAP 2026 tests. Germany is planning vehicle benchmarks and subjective tests. Japan is conducting vehicle evaluation tests using two passenger vehicles with three target types based on UN R175 01 series test procedures. The next coordination meeting is scheduled for 10 November 2026, with an in-person meeting in Tokyo proposed for February 24–26, 2027.

Proposal to insert definitions for Software Identification Number, insert requirements for manufacturers to provide necessary information allowing the Technical Service to uniquely identify hardware and software configurations, insert provisions allowing vehicle manufacturers to apply for new approvals to differentiate software versions for registered versus new vehicles, amend production discontinuation provisions to clarify that cessation is not deemed definitive if the manufacturer intends to obtain subsequent extensions for software updates of vehicles already registered in the market, renumber and insert new items in approval communication annexes regarding software identification and software updates including RxSWIN, and insert provisions allowing vehicle manufacturers to obtain new approvals for software version differentiation across multiple UN Regulations (13, 13-H, 79, 89, 130, 131, 139, 140, 152, 155, 156, 157, 171, 175, and 178).

Proposal to insert provisions on Software Identification Numbers and software updates across UN R13, R13-H, R79, R89, R130, R131, R152, R155, R156, R157, R171, R175, and R178 by adding definitions referencing Consolidated Resolution R.E.3 Annex 7 paragraph 2, requiring manufacturers to provide Technical Services with information on hardware and software influencing performance with test reports, permitting vehicle manufacturers to apply for new approvals differentiating software versions for registered vehicles from new vehicles where type approval regulations are updated or hardware changes occur in series production with test duplication avoided where possible, clarifying that production is not considered definitively discontinued if manufacturers obtain subsequent extensions for software updates of registered vehicles, renumbering and inserting new items in approval communication annexes for R13SWIN, R13-HSWIN, R79SWIN, R89SWIN, R130SWIN, R131SWIN, R152SWIN, R155SWIN, R157SWIN, R171SWIN, R175SWIN, and R178SWIN information including whether held on vehicle and relevant parameter identification lists, and amending R157 and R171 to align software update requirements with R156 technical specifications and transitional provisions.
