49. The representative of Germany presented a proposal to improve the AEBS Regulations (GRVA-23-06) based on research conducted by the German Federal Highway and Research Transport Institute. He suggested several workstreams for GRVA: AEBS for pedestrian in night conditions, AEBS for blind spot detection in the context of UN Regulation No. 151 and AEBS in the context of ACPE. Several delegations expressed positive reactions, the representatives of Canada and Denmark exchanged views on pedestrian detection for trucks and the maturity of such systems.

51. The representative of France presented an amendment proposal to UN Regulation No. 152 aimed at clarifying the application of the footnote in the scope of the regulation, treating UN Regulations Nos. 131 and 152 on equal footing for heavy vehicles and so that Contracting Parties to UN Regulation No. 131 should recognize approvals pursuant to UN Regulation No. 152. The representative of AAPC recalled similar discussion in the context of UN Regulation No. 160 (EDR). He invited GRVA to consider precedents in other regulations. The representative of OICA supported the proposal in general and offered to provide some modifications. On the same topic, the representative of the United Kingdom of Great Britain and Northern Ireland proposed an alternative approach, noting the different focus for the type of scenarios to be address under the two regulations. He commented that the choice to apply the proposal from his Country or from France would depend on government views on which type of scenarios were most relevant for the vehicle category at stake. He confirmed that his approach was aligned with the approach selected for UN Regulations Nos. 160 and 169. The representative of OICA explained that GRVA-23-36/Rev.1 would require re-approving existing vehicles.

52. GRVA requested the secretariat to distribute GRVA-23-36/Rev.1 with an official symbol at the January 2026 GRVA session and to keep GRVA-23-08 on the agenda that session.

50. The representative of France presented considerations (GRVA-23-09) on the possible improvements of AEBS Regulations, based on lessons noted from a fatal crash in Paris and on the media reports highlighting false positives in real driving conditions leading to concerns. He mentioned that hundreds of reports were submitted to the French market surveillance authority. The representative of OICA recalled that pressing the acceleration pedal was one of the way to suppress undesired AEBS intervention. He noted that speed of the vehicle involved in the crash mentioned (140 km/h in urban conditions) and wondered whether the main cause of that fatal accident was related to the AEBS regulations. Several delegations called for addressing the issues in phases. GRVA agreed with the organization of a workshop in January 2026 to explore the data available and advise GRVA on possibilities to consider for improving the AEBS regulations.

53. The representative of Japan presented GRVA-23-40 proposing to clarify the GRVA position on the right way to read the supplements of UN regulation No. 152 concerning the tolerance in para. 6.6.1. The document proposed to adopt amendments (that might be considered redundant) or Corrigenda to clarify the reading of this paragraph. GRVA confirmed that the original intention of the IWG on AEBS was that the tolerance of 0.4 km/h shall apply to all series of amendments and requested the secretariat to correct the necessary documents accordingly.

54. The representative of the United Kingdom of Great Britain and Northern Ireland presented document ECE/TRANS/WP.29/GRVA/2025/42 clarifying the wording “run cycle” in UN Regulation No. 130, as already done for several regulations at previous GRVA sessions. GRVA adopted the proposal as supplements to the original and the 01 series of amendments to UN Regulation No. 130 (LDWS) and requested the secretariat to submit them to WP.29 and AC.1 for consideration and vote at their March 2026 sessions.
