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.
The agenda includes discussion of preliminary outcomes and planning research activities. Future sessions are scheduled for September 8th, 2026, November 10th, 2026, and January 2027 in Japan before GRVA-27.
This presentation, intended for discussion within TF Data Analysis RD-ASEP and not for conclusions, analyzes model performance using L_exp data from Annex_9_test_runs where both left and right sound were measured. Model performance varies across speed bins, with higher mean absolute error at low and high speeds. Adjusting theta_tr values improves mean absolute error across all speed bins. Testing without an envelope function results in more measurements exceeding expected values, requiring extra margins.
GRVA may wish to be briefed on the input from WP.29 regarding the May 2027 session envisaged to be organized in China.
