100. The Secretary reported on the GRVA workshop dedicated to Electro-Mechanical Braking (EMB) that took place on 29-30 March 2023 (GRVA-16-11). He informed GRVA that participants discussed the review of the current EMB technology, Periodical Technical Inspection considerations for such systems, Brake By Wire (BBW), issues related to the traction battery and battery ageing. He recalled the conclusion of the workshop, which were the wish of working in a first step on the principles rather than on definitions, and the proposal to establish a new working structure at this session, e.g. a special interest group to accelerate progress.

101. The expert from UK presented a proposal on drafting guidance principles for UN Regulations Nos. 13 and 13-H (GRVA-16-07). He stated that the document set out seven performance-based principles and described how they could be beneficial when drafting provisions for new technologies related to braking systems employing stored energy, while still respecting the intent of the regulations.

102. The experts from CLEPA, Germany, Japan and OICA generally supported these principles and expressed the need to continue the activities related to EMB.

103. GRVA endorsed GRVA-16-07 as a guidance document for further activities on EMB.

104. The expert from CLEPA introduced draft ToR and Rules of Procedure (RoP) for a potential Special Interest Group (SIG) on EMB and BBW (GRVA-16-17), proposing one subgroup to address UN Regulation No. 13 and another subgroup to focus on UN Regulation No. 13-H. He offered to take on the role of the Secretary for that SIG.

105. The expert from UK presented alternative draft ToR, RoP and deliverables of a potential SIG on EMB (GRVA-16-27), aiming at a harmonized approach and understanding for UN Regulations Nos. 13 and 13-H. He proposed to establish one subgroup solely dedicated to principles around energy supply and another subgroup tackling the challenges the technology presents. The expert from UK volunteered to provide the Chair of SIG.

106. The experts from CLEPA and Japan supported the UK proposal. The expert from Japan suggested to remove the square brackets in paragraph 8.

107. The expert from China informed GRVA about his interest to participate in SIG on EMB, as it was an important topic for future technologies.

108. GRVA endorsed the draft ToR and RoP of SIG on EMB reproduced in Annex IV (based on GRVA-16-27 as amended during the session).

109. The expert from UK requested to keep ECE/TRANS/WP.29/GRVA/2023/10 and GRVA-16-41 on the agenda until the next session, as they would be further discussed and finalised by SIG on EMB. GRVA agreed to this proposal.
