| GRVA | Session 13 | 23-27 May 2022 |
74. GRVA received the final report (GRVA-13-40/Rev.1) from the expert from Germany, Co-Chair of the IWG on Advanced Emergency Braking Systems (AEBS) for heavy duty vehicles, on the progress made by the group to upgrade and align UN Regulations Nos. 131 and 152. He introduced GRVA-13-09 and GRVA-13-10 and also referred to GRVA‑10‑33 tabled by the expert from OICA. 75. The expert from the European Commission, Co-Chair of the IWG on AEBS for M1 and N1, introduced GRVA-13-08 and GRVA-13-30. 76. GRVA requested the secretariat to distribute GRVA-13-08, GRVA-13-09 and GRVA-13-10 with official symbols at the next GRVA session in September 2022. 77. GRVA agreed that the expert from EC would submit a revised proposal, or a working document based on GRVA-13-30, potentially merged with GRVA-13-08, for consideration at the next GRVA session in September 2022. 78. The expert from OICA introduced GRVA-13-33 concerning the interpretation of the wording “new engine start/run cycle”. GRVA supported the interpretation 1 referred to in that document and requested that proper attention is given to the French translation of the corresponding text in the Regulation. 79. GRVA thanked the IWG for their work and contributions to finalise the work to update the requirements on AEBS for heavy duty vehicles. |
