Transport Canada presented ACPE research testing comparing three vehicles—2025 Tesla Model 3, 2025 Subaru Forester, and 2025 Toyota Crown Signia—against UN R175 minimum performance requirements and real-world pedal misapplication crashes. Analysis of 14 EDR data cases revealed none would require ACPE intervention under current R175 criteria. Testing included UN R175 procedures and recreation of six real-world crash scenarios. Proposed 2026 research includes investigating radar signatures of wall structures, obstacle distances exceeding 1.5 metres, accelerator pedal application rates and travel, and false positive test procedures.

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.

Proposal based on informal document GRVA-25-43 to amend Annex 4, para. 3.5.1. to require the manufacturer to demonstrate to the Type Approval Authority at least every three years that the safety management system continues to comply with requirements for software and hardware employed in the system. This amendment applies the same principle regarding Safety Management System compliance as specified in UN Regulation No. 171 on Driver Control Assistance Systems.

Proposal to insert para. 3.2.2. requiring manufacturers of Automated Lane Keeping Systems active in multiple Contracting Party territories to provide information on traffic rules identification, territory-specific testing, and contact details, insert paras. 4.8. to 4.8.6. establishing procedures for granting approval authorities to inform and consult receiving approval authorities at least 30 days before approval, allow receiving authorities 30 days to comment on regulation interpretation, require dispute resolution under Article 10 and Schedule 6 of the 1958 Agreement, and insert footnote [Y] stating these provisions shall be kept under periodic review by GRVA for amendment as necessary.
