96. The representative of the United Kingdom of Great Britain and Northern Ireland, Chair of the Special Interest Group on Electromechanical Braking, presented the status report of the group (GRVA-17-19). He alerted GRVA on the ambitious schedule proposed by the group as well as on the concept being developed, which might require careful review by the delegations. The representative of CLEPA provided details on how the industry is envisaging such systems. The group invited GRVA to reflect on the fact that these new braking systems may not measure but deduce the level of energy available for braking, may not have an energy reserve strictly dedicated to braking, may use an energy reserve that is available to several vehicle systems as an energy storage device for the braking system.

97. Several delegations offered comments, stating that an indirect deduction might be acceptable if a robust validation is available and asking the group to envisage limitations in case the energy reserved could be used by non-safety critical systems. They also inquired what the group would do to address the case were several safety critical systems e.g. steering an braking would share the same energy reserve. GRVA supported the path taken by the group so far.

98. The representative of the United Kingdom of Great Britain and Northern Ireland clarified, upon request, that the consideration their amendment proposal to Annex 18 of UN Regulation No. 13 with the requirements for electronic vehicle control systems (ECE/TRANS/WP.29/GRVA/2023/10) could be postponed until the January 2024 session, while the EMB documents are being developed.

99. The representative of CLEPA clarified that the consideration of the amendment proposal to UN Regulation No. 13 to consider the approval of the so-called e-axles (ECE/TRANS/WP.29/GRVA/2023/3) can be postponed until the January 2024 session of GRVA.
