The agenda includes discussion of research outcomes and possible conclusions, other business, and list of action items and next meetings. The next meeting is scheduled for 12-14 January 2027 in Japan with 15 January 2027 for leadership to prepare report for GRVA.

The session includes discussion of preliminary outcomes and ongoing research activities, other business, and list of action items and next meetings.

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.

The 3rd session of the Acceleration Control for Pedal Error Global Technical Regulation met online in May 2026. No vehicles have been certified under UN R175. Korea presented interim research on pedal operation speed and misapplication accident patterns, with results expected in 2026. Multiple contracting parties are conducting ongoing research on activation distance ranges, pedal application rates, and wall obstacle activation. The group endorsed research priorities and agreed to reconvene online on July 8th, 2026, with an in-person meeting planned for January 2027 in Japan.

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.

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.

Research plan for ACPE vehicle performance. Tests using actual vehicles will evaluate ACPE performance of vehicles on the Japanese market. Tests specified in UN R175 01 series will be conducted, along with tests under extended conditions with partially expanded test parameters. Test procedure for creeping vehicle specified in UN R175 01 series, paragraph 6.6.2, will be conducted. Activation limits of ACPE will be confirmed using distance to target and pedal application speed as test parameters. Tests will use one 2026 model year Suzuki Swift and one 2026 model year Daihatsu Move. Vehicle procurement by end of September, testing late October to November, data analysis by end of December, summary of research results early January.

The Korea Automobile Testing & Research Institute presents two planned ACPE GTR studies. Study #1 on normal pedal operation speed range is in pre-R&D phase with data collection ongoing from elderly drivers; results will not be presented in 2026 due to required data processing and insufficient time for statistically meaningful analysis. Study #2 analyzes pedal misoperation speed using 10 Hz EDR data from nine real-world crash cases where manufacturers concluded no vehicle defects. Analysis is in progress with results to be shared at subsequent meetings as additional cases are confirmed.

No vehicles have received certification under UN R175-00/01. The document lists representative ACPE-equipped vehicle models from various manufacturers and markets, detailing their sensor configurations, target objects, and operation speed ranges. Sensor types include ultrasonic sonar, monocular camera, stereo camera, and milli-wave radar. Target objects are stationary objects and pedestrians. Vehicles exhibit variation in forward and rearward equipment and low-speed braking function inclusion. Performance definitions differ by OEM and are not directly comparable across manufacturers or to UN R175 requirements.

The informal working group on Global Technical Regulation for Acceleration Control for Pedal Error will meet on May 8th, 2026 via MS Teams from 12:00 to 14:00 CEST. The agenda includes approval of the agenda, adoption of the draft report for the previous meeting, review of a list of ACPE-equipped vehicles, preliminary outcome and planning research activities, coordination of research activities, other business, and a list of action items and next meetings.

The draft document identifies potential research questions for ACPE (Acceleration Control for Pedal Error) systems across three categories: basic data collection on system specifications and cost-benefit analysis; performance requirements and test procedures; and human factors analysis. Research priorities include surveying existing ACPE technologies, analyzing accident data and system costs, establishing control philosophy, defining triggering conditions, and investigating pedal misapplication.
