Proposal to clarify components and functions of the ADS and other vehicle systems relevant to meeting the requirements of the regulation (paras. 5.3.1.4.2 (GTR)/7.3.1.4.2 (UNR)). The revised text specifies that other vehicle systems could include shared components or functions such as sensors, map data, and GNSS used for assistance systems or positioning. Information from outside the vehicle may be included if used to meet regulation requirements. The manufacturer could use different diagram types provided information is present, and additional information regarding wireless links could be included.

Transport Canada ACPE Research Plan 2026 sets out testing expected August and September 2026, with preliminary results expected in November. Testing addresses sonar sensor response to different materials, ACPE system characterization including coarse and refined screening with varying accelerator application rates, distances, target types, speeds, and directions, baseline response with no obstacle, and false positives using test vehicles 2026 Passport, 2026 Solterra, and 2026 Prius.

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.
