88. GRVA resumed its discussion on park brake warning requirements in the case of electric parking brakes, based on a revised proposal in GRVA-13-22 and the supporting material in the presentation GRVA-13-25. Following discussion, GRVA developed a revised proposal.

89. GRVA adopted GRVA-13-22/Rev.1 (based on ECE/TRANS/WP.29/GRVA/2022/11 and reproduced in Annex III) and requested the secretariat to submit it, as supplements to the 11 and 12 series of amendments to UN Regulation No. 13, to WP.29 and AC.1 for consideration and vote at their November 2022 sessions.

8. (c) | Clarifications

84. The expert from OICA presented GRVA-12-48, proposing to allow that the required warning actuation may be delayed until the parking brake was in a stable state. The proposal received comments from France, Germany, United Kingdom of Great Britain and Northern Ireland and Russian Federation. GRVA agreed that the expert from OICA, in consultation with interested Contracting Parties, would submit a revised proposal on the basis of ECE/TRANS/WP.29/GRVA/2022/11, at its May 2022 session.

8. (c) | Clarifications

93. The expert from OICA introduced GRVA-11-42, an amendment proposal to clarify the warning actuation requirements in case the parking braking system would be automatically requested to apply the parking brake. GRVA requested the secretariat to distribute GRVA-11-42 with an official symbol at the next session.
