Proposal to remove guidance on prevention of unsafe takeovers. The document proposes deletion of the statement “Such an occurrence is expected to be reported when situation is unsuitable or unsafe for the subsequent mode of vehicle operation” from para. 15 of GTR Annex 1/UNR Annex 3, with no replacement text provided. The rationale indicates this removal reflects OPI group discussions aimed at finalizing the GID by resolving remaining open items.
Proposal to delete reference to no response within required time in section 14 on fallback user unavailability, and add reference to para. 4.2.2.1.6 (c) as the requirement for reporting MRC required due to non-response.
Proposal to add a note that no guidance is provided on reporting when a feature required remote interaction to navigate a situation. The revised text adds that an active ADS feature required remote interaction to navigate a driving situation and marks guidance as N/A. This change was accepted as amended following OPI-group discussions aimed at finalizing the GID by reaching a compromise solution on remaining open items.
Proposal to clarify guidance on reporting unauthorized modifications to the ADS by deleting “Such an occurrence is expected to be reported in case of” and replacing it with “Examples of unauthorised modifications to the ADS could include”, deleting “Sensor tampering; obstruction;” and inserting language to specify that ADS-relevant software or hardware tampering, or third-party hardware interfering with ADS, could constitute unauthorized modifications affecting intended functionality.
Proposal to clarify guidance on reporting maintenance and repair issues by deleting “Such an occurrence is expected to be reported in case of” and inserting “Examples of maintenance or repair issues could include”, adding “safety-critical” before “software”, adding “potential” before “safety”, deleting “implications” and inserting “consequences, or”, deleting “Fitted hardware not compliant to safety performance specifications” and inserting “Not following the repair instructions given by the manufacturer.”
Proposal to add para. 4.4.1. through 4.4.8. to restructure target operation conditions provisions, add para. 4.4.7. to permit acceptance of runs outside the control range under specified provisions, modify para. 3.6.1. to change reference acceleration determination from maximum to selected acceleration for a selected reference v-t-e ratio, modify para. 4.5.4.1. to set negative calculated acceleration values to zero, add heading “Carry-over parameters from Annex 3” to para. 2.2.1.2., add para. 2.2.1.2.1. and 2.2.1.2.2., and modify constant speed test parameters to report vehicle speed vBB’_CRS_ANCHOR rather than reference speed vTEST of 50 km/h.
Task Force Data Analysis held an online meeting on 7 July 2026. The group discussed database analysis, including insufficient data for higher performance and acceleration, and agreed that more data are needed. When new data are generated, operation conditions should focus on higher performances covering the ASEP range, higher accelerations up to and exceeding 5 m/s, pass-by runs with gear shifting, and low speed measurements in the UN R117 AVAS control range. The group reviewed proposals to the TF-Editing based on draft UN R51.04 and agreed some changes, with review results to be uploaded as Rev.1. A question regarding the phrase “but no more than 2.0 m/s” in paragraph 3.1.2.1.4.3 regarding vehicles with only one gear ratio was noted as issue #23 pending further review.
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.
