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.

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.

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.

Proposal to insert new paragraphs in Section I defining the background, scope, and technical rationale for emergency door opening provisions addressing power loss scenarios, insert new paragraphs 3.25. to 3.31. in Section II defining terms including “latch release control”, “door handle”, “retractable door handle”, “unlock”, “unlatch”, and “power loss”, insert new para. 4.3. establishing requirements for exterior and interior door operation with intuitively accessible latch release controls and door handles on doors providing direct occupant access, insert new para. 5.4. specifying that latch release controls and door handles shall be intuitive, that power-assisted latch release controls shall remain capable of unlatching doors after power loss for at least 60 minutes through secondary mechanical means, active secondary power supply, or fail-safe systems, that power-assisted latch release and unlocking controls shall similarly remain functional after 60 minutes of power loss, that power-assisted door opening systems shall remain manually openable after power loss, that door handles including retractable door handles shall provide accessible gripping features to unlatched doors after power loss, and that unlocking means and latch release controls shall be unobstructed, directly visible, and not located in storage devices or obstructed by interior components, and insert new Annex 6 specifying test procedures for interior and exterior door operation after power loss, including vehicle preparation steps, 60-minute waiting periods, and opening procedures to be completed within 10 minutes with up to five cycles per door.

The document addresses open issues and comments regarding UN R11 and GTR No. 1 concerning emergency door opening. It proposes defining vehicle master control switch as the device bringing onboard electronics from off to normal operation mode, and suggests activating this switch rather than switching ignition on in test procedures. The document defines main power supply as power source(s) and supply path(s) normally used for door system operation, excluding secondary or back-up supply. It raises concerns about secondary or back-up power supply failure occurring in the field before emergencies despite compliant test results. The document discusses objective intuitiveness criteria including visibility, accessibility, discoverability, identification, and operability. It recommends standardized marking for exterior door handles and proposes that door opening and closing procedures be described in vehicle owners’ manuals.

Methods for evaluating electromagnetic immunity of blind-spot detection systems are proposed using a simple reciprocating motion device equipped with a reflector. The electromagnetic immunity test is conducted after the BSD system has been activated. Vehicle’s electromagnetic immunity test methods and conditions are consistent with the previous ones. Reproducibility has been verified across various vehicle models with only minor adjustments required. The proposal seeks opinions from member countries regarding the necessity of electromagnetic immunity evaluation methods for BSD systems.

Proposal regarding methods for evaluating electromagnetic immunity of blind-spot detection systems. The proposal identifies this as a subject for discussion as part of ADAS evaluation methods. The form requests consideration of revisions to evaluation methods, with reference to presentation materials. The proposal’s disposition status remains to be determined by the IWG.

Proposal to clarify para. 5.6.4.6.8.1.(e) of UN R79 to address how different direction indicator lever mechanisms comply with manual deactivation requirements for automated lane change systems. The regulation currently does not distinguish between full-turn methods, where the lever returns to neutral position, and half-turn methods, where activation of the opposite direction indicator or stalk activation in the opposite direction constitutes deactivation. Two options are presented: either add separate provisions for each method, or note that activation of opposite direction indicator lamps may constitute deactivation of the initiating signal.

Document presents Korean research on event data recorder (EDR) data survivability in electric vehicles following post-crash fires. Analysis of nine Korean EV fire cases shows EDR data retrieval failed in three cases due to ACU damage in fully burned vehicles, while six cases achieved data retrieval despite water immersion from firefighting. The document proposes water immersion testing to assess EDR data survivability for inclusion in EDR Step 3, referencing international automotive standards for test method development.

This document addresses rear direction-indicator lamps mounted at low positions on vehicles. Republic of Korea reports increased public petitions and media articles regarding visibility and recognition concerns, particularly in congested traffic and for vehicles with higher driver seating positions like SUVs. UN Regulation No. 48 specifies direction-indicator lamp height requirements: not less than 350 mm and not more than 1,500 mm, or up to 2,100 mm under certain structural conditions. The presentation seeks feedback on similar issues from other countries and manufacturers.
