Proposal for a new UN Regulation for the type approval of automatic emergency braking systems designed to protect vulnerable road users from collisions with heavy vehicles travelling at low speeds. The purpose is to enable a cross-reference in the new UN Regulation on commercial vehicle direct vision to allow for alternative solutions and performance criteria for vehicles equipped with this “urban emergency braking system” capability.

88. The expert from Germany presented GRVA-14-37, introducing ECE/TRANS/WP.29/GRVA/2022/24, a proposal to harmonize requirements on Urban Emergency Braking System (UEBS) via a new UN Regulation that would address specifically heavy vehicles travelling at low speeds and would aim at the protection of vulnerable road users. He stated that, with this UN Regulation, the direct vision regulation under the purview of GRSG could be amended so as to have different performance criteria for vehicles equipped with this UEBS.

89. The expert from Denmark introduced GRVA-14-10. He delivered a statement on the situation in Ukraine (see Annex III). The expert from the Russian Federation answered via comments in the chat tool of the meeting, other statements were submitted to the secretariat, for reproduction in the report, see Annex III. The expert from Denmark explained that a new UN Regulation on UEBS could be discussed separately from the considerations related to the GRSG activities on direct vision. He proposed to amend UN Regulation No. 131 instead of adopting a new UN Regulation. He provided technical comments on the draft provided by Germany in order to better address real life conditions. The expert from the Netherlands supported the views expressed by Denmark and stated that UEBS should not water down the direct vision requirements developed by GRSG. He acknowledged the big step recently achieved with the upgrade of UN Regulation No. 131 (including requirements regarding pedestrian and cyclist detection) but he also noted potential actions in order to better address real conditions. He agreed with Denmark on the shortcomings of ISO 19206-4:2020 referred to in UN Regulation No. 131, not being sufficiently representative of cyclists.

90. The expert from OICA expressed concerns regarding the statements related to real condition performance. He stated that UN Regulations Nos. 131 and 152 both prohibited that AEBS change the control strategy in conditions other than those tested. He noted the ambitious proposal of Germany, that UEBS was not aimed to be an ADS but that it could be intrusive in the driving task. He expressed concerns that UEBS could be made mandatory, when UN Regulation No. 131 just completed its review.

91. The expert from Germany proposed to keep this item on the agenda, to present UEBS to GRSG and to consult WP.29 if an IWG could review the proposal. GRVA agreed that it was up to Germany to decide whether or not to present UEBS to GRSG and that contacts with GRSG would be welcomed to work towards a common understanding. GRVA requested the Chair to inform WP.29 at its November 2022 session about the ongoing discussions on the proposal (ECE/TRANS/WP.29/GRVA/2022/24).

104. The expert from France presented GRVA-15-20 introducing GRVA-15-19, with an amendment proposal to UN Regulation No. 152, aimed at introducing provisions for computer simulation of dynamic tests. He explained the history of the proposal. The expert from Japan commented that real driving conditions had to be considered in this context and that the validation requirements for AEBS would potentially require more physical tests than currently required.

105. GRVA reviewed the draft consolidations of UN Regulation No. 152 prepared by the secretariat (GRVA-15-50 and GRVA-15-51) and provided comments.

106. GRVA agreed to keep ECE/TRANS/WP.29/GRVA/2022/24 (proposal for a new UN Regulation for Urban Emergency Braking System) as well as GRVA-15-19 and GRVA‑15‑20 (AEBS virtual testing) on the agenda for its next session.

89. GRVA agreed to keep ECE/TRANS/WP.29/GRVA/2022/24 (Urban Emergency Braking System (UEBS)) on the agenda for its next session.
