Session 76 | Geneva | 17-21 Feb 2014
Agenda Item 3. (c) Clarifications
Working Party on Brakes and Running Gear | Session 72 | 20-24 Feb 2012

11. GRRF noted the outcome of the discussion in WP.29 on dynamic/static references to other UN Regulations and private standards (see report ECE/TRANS/WP.29/1093, paras. 48 and 49). GRRF endorsed the recommendation to proceed on a case by case approach awaiting a final decision by WP.29 at one of its next sessions.

12. The expert from CLEPA introduced ECE/TRANS/WP.29/GRRF/2011/35/Rev.1 clarifying the levels of braking performance of vehicles in relation with different positions of the ignition key. GRRF noted a number of comments. Following the discussion, CLEPA presented GRRF-72-27 amending ECE/TRANS/WP.29/GRRF/2011/35/Rev.1. GRRF adopted the proposal, as reproduced in Annex II, and requested the secretariat to submit it to WP.29 and AC.1, for consideration at their June 2012 sessions, as Supplement 14 to Regulation No. 13-H.

13. Recalling the purpose of WP.29-155-19, the expert from EC withdrew ECE/TRANS/WP.29/GRRF/2012/9. As a consequence, the expert from CLEPA withdrew ECE/TRANS/WP.29/GRRF/2012/7. Nevertheless, the experts from Germany, Japan and OICA expressed their support for ECE/TRANS/WP.29/GRRF/2012/9 and their preference to keep it on the agenda. The Chair concluded that the item should be revisited, together with the related document from CLEPA (GRRF-72-17), at the next GRRF session on the basis of a new proposal, if available.

14. The expert from Belgium reported on the progress (GRRF-72-08) made by the informal group on Alternative Method Electronic Vehicle Stability Control (AMEVSC). On behalf of informal group, the expert from CLEPA proposed to use simulation tools to prove compliance of the vehicle stability function (ECE/TRANS/WP.29/GRRF/2012/2). The expert from OICA introduced GRRF-72-22 on some weaknesses in the current simulation tool. GRRF noted a number of comments and agreed to refer the proposal back to the informal group. GRRF agreed to resume consideration on this subject at its next session on the basis of a revised proposal to be submitted by the informal group, taking into account GRRF-72-17, GRRF-72-22 and the comments received. GRRF noted that the informal meeting was scheduled to be held in Brussels (at CLEPA offices) on 10-11 May 2012.

15. The expert from Germany introduced ECE/TRANS/WP.29/GRRF/2012/11 and GRRF-72-28 on the introduction of an electro-hydraulic transmission for electrical brake systems. GRRF noted some concerns and agreed to resume the discussion on this subject to the next session of GRRF on the basis a revised proposal, if available.

8. The Chair recalled the purpose of ECE/TRANS/WP.29/GRRF/2012/11 on introducing an electro-hydraulic transmission for electrical brake systems. The expert from Germany reported on the progress made. He added that a revised proposal might be submitted for consideration at the September 2013 session of GRRF. GRRF agreed to resume the discussion at its next session, keeping the document as a reference.

9. The expert from Japan introduced ECE/TRANS/WP.29/GRRF/2013/3, superseding ECE/TRANS/WP.29/GRRF/2011/34 and proposing clarification on the reference to Regulation No. 10 in Regulations Nos. 13 and 13-H. The expert from OICA introduced GRRF-74-13, proposing a similar amendment to Regulations Nos. 13 and 13-H but also amending Regulations Nos. 79 and 89 as well as the new Regulations on Advance Emergency Braking System (AEBS) and Lane Departure Warning System (LDWS). Following the discussion, the expert from the Russian Federation withdrew GRRF-74-33. GRRF agreed to reconsider GRRF-74-13 at its next session on the basis of an official document.

10. The expert from Germany introduced ECE/TRANS/WP.29/GRRF/2012/21, proposing to remove the signature of the Type Approval Authority from the test report defined in Annex 12 of Regulation No. 13. GRRF adopted this document and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their June 2013 sessions as part of draft Supplement 10 to the 11 series of amendments to Regulation No. 13 (see para. 5).

Working Party on Brakes and Running Gear | Session 75 | 17-19 Sep 2013

11. The expert from Germany presented ECE/TRANS/WP.29/GRRF/2013/29 introducing provisions for electrical or hydraulic transmissions for brake systems. The expert from OICA, with reference to GRRF-75-13, answered to this proposal. GRRF noted a number of comments and agreed to resume consideration of this item at its next session on the basis of a revised document that the expert from Germany volunteered to prepare.
