Unlock refers to transition of a doorlatch system into a state in which operation of the latch-release control is no longer inhibited, allowing the latch to disengage from the striker. Unlatching refers to transition into a state in which the latch and striker are no longer capable of withstanding separation forces, thereby allowing the door to move away from the vehicle body structure. Opening refers to the action by which a door is moved from its closed position to an open position through mechanical force or energizing an actuated device. Child Safety Lock System is a locking device which, when engaged, prevents operation of the interior door handle or other release device.

UN R155: Guidance for transformed vehicles
Reference Number: TFCS-37-05

Proposal to provide guidance on application of UN R155 to transformed vehicles. Transformations require new approval unless clear evidence shows original approval remains valid. Cyber-relevant modifications include addition of electrical/electronic systems, inappropriate interface connections, and wiring protection modifications. The approval authority determines whether transformation is cyber-relevant by assessing impact on original vehicle architecture, connection risks, cybersecurity management systems, and whether non-automotive equipment complies with relevant regulations. Manufacturers must provide documentary evidence including functional descriptions, connection details, software modifications, and compliance with original manufacturer instructions.

UN R155: Proposal for amendments from the workshop discussions
Reference Number: TFCS-37-04

Proposal to amend UN R155 by clarifying its scope to exclude certain equipment. The proposal amends paragraph 5.3.2. to require approval authorities to notify others of assessment methods and criteria. New paragraphs 8.2. and 8.3. establish that vehicle manufacturer installation of equipment with negligible intrinsic cyber security risk, or standard domestic, business or industrial equipment connected only for power, shall not require further assessment under paragraph 7, provided specified criteria are justified. Annex I is amended to include any equipment excluded from assessment pursuant to paragraphs 8.2. and 8.3.

ADS: Correction to the DSSAD annex in the draft UNRsubmission
Reference Number: ADS-20-16

Proposal to amend WP.29-198-09. The proposal modifies paragraph 5.3.2 to specify that visual images are mandatory data elements to be recorded during a triggering event, with a recording interval of minus 7 to plus 7 seconds relative to the triggering event. The EDR/DSSAD-IWG has agreed to set the condition for requirement field to “Mandatory” in the visual image table.

UN R53: Presentation on transitional provisions
Reference Number: SLR-77-15

Based on SLR-76-03-Rev1 for R48 and tentatively applying WP.29/2024/76, IMMA presents transitional provisions for UN R53. The document outlines provisions applicable to all amendment series, including that Contracting Parties may grant type-approvals according to any preceding series and shall continue granting extensions of existing approvals. For the 05 series of amendments, specific dates establish when Contracting Parties shall accept or refuse type-approvals, with exceptions for equipment, parts, and unaffected vehicle systems.

Proposal for Amending Guidance on Event Data Recorder (EDR) Performance Elements
Excerpts from session reports
WP.29 | Session 183 | 9-11 Mar 2021

98. The representative from the United States of America, Co-Chair of the IWG on EDR/DSSAD recalled the deliverables produced by the group in 2020: the DSSAD part of UN Regulation No. 157 and the work on a new UN Regulation on EDR. She informed WP.29 that the discussions on the document on EDR Performance Elements Appropriate for Adoption under the 1958 and 1998 Agreements related to the additional data-elements to be captured by an EDR had not been concluded by the group. She said the IWG welcomed any
guidance from WP.29 members on the elements in the document that were still in square brackets, but noted that document was not ready for final consideration by WP.29.

99. She requested extension of the mandate for the group until end of 2022. She noted that in 2020, the IWG focused its efforts almost entirely on drafting the UN regulation for EDRs and with that work completed, the group intended to focus on DSSAD as well as phase II of EDR, focusing on the extension of scope to heavy duty vehicles and buses in 2022.

100. The representative of the European Commission supported the extension of the IWG’s mandate and referred to the European Union programme of work that includes EDR related elements such as extension of scope to heavy duty vehicles in addition to DSSAD for automated vehicles.

101. The Chair of GRVA noted the close interlinkage of the activities of the IWG on EDR/DSSAD with IWGs on VMAD and FRAV. He urged the EDR/DSSAD IWG to prioritize the work on data storage systems for the calendar year ahead now that the EDR regulation had been sent to WP.29 and recalled that the mandate extensions for VMAD and FRAV would be addressed during the special session of AC.2 designated to the topic of vehicle automation.

102. WP.29 adopted the extension of the mandate for the IWG on EDR/DSSAD until 2022.
