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.

Proposal for ACSF systems to be programmed to function only within the maximum speed limits defined by national or regional traffic authorities.

The draft amendment to enable automated steering systems for use at speeds above 10 km/h includes provisions for a minimal risk maneuver (MRM) in the event that the driver fails to respond to a demand to assume control of the vehicle. This document proposes provisions for the automatic activation of hazard warning lights under an MRM scenario.

Presentation on the detection of the range of a vehicle approaching from behind a vehicle operating under automatically commanded steering (e.g., detection of a fast approaching vehicle in order to avoid a dangerous lane change).

Korea input regarding criteria for ensuring automated vehicles maintain a safe following distance from preceding vehicles as a function of time in seconds.

Discussion of automated vehicle emergency response to an imminent collision (vehicle cut-in, lead vehicle deceleration, unforeseen obstacle, etc.).

V2H Communication System Research Results documents a National Project supported by Korea’s Ministry of Land, Infrastructure and Transport conducted across three phases from 2021 to 2026. The research develops vehicle-to-human communication technology for autonomous driving systems through study of communication cases, validation of V2H elements, technology development, and road demonstrations. Survey findings indicate hybrid projection and display approaches achieve 77.7% positive response rates. Trust in autonomous vehicles increased from 24.0% to 41.5%, and safety perception improved from 21.6% to 37.3%. Projection messages reduce pedestrian crossing decision time by 3.64 seconds and ensure 100% crossing decisions with yielding messages across all demographics. Cyan-colored text-based messaging demonstrates superior visibility and user preference ratings of 3.9 to 4.2 on a 5-point scale compared to symbol-based formats.

KATRI reported on the 131st GRSG session. OICA raised concern that the scope of the draft regulation is not clear, noting that vehicles of categories M₂ or M₃ class B and III designed or equipped primarily for the carriage of children equals all of M₂ or M₃ vehicles since there is always a possibility of carrying children, and stated it is now checking TF STBC documents. CIVD stated that vehicles used for camping need to be exempted from scope, noting this is reasonable but questioning how. Denso asked whether warning method of visual and audible is different between buses and light vehicles, noting this is done, and stated it seems possible to add new regulation number in UN R48.

Presentation of open issues concerning the testing and approval of deployable pedestrian protection systems.

Comments address proposals EDO-05-03e and EDO-05-04e. On intuitiveness, the definition was agreed upon but concerns remain regarding ambiguity under self-certification system. Specific examples may be included such as door handle with gripping space, and mark/label/symbol on latch control. On power loss test, overall test procedures were agreed upon. Clarifications needed include normal riding position in 2.2.3., and whether interior test testers proceed with opening procedure after 60 minutes for all doors with 4 times repetition per door within 60 minutes proposed.
