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.

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.

Proposal for revised terms to include the development of a GTR on ACPE.
