Proposal by the informal group on Alternative Method Electronic Vehicle Stability Control (AMEVSC) to clarify the requirements of Regulation No. 13 regarding the use of simulation, specifically in the Appendices 1, 2 and 3 of Annex 21.
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.
31. GRRF reviewed ECE/TRANS/WP.29/2012/2 clarifying in Regulation No. 117 the current wet grip testing method and adding specific performance requirements for C3 snow tyres. GRRF agreed to go forward with the proposed agenda of the March 2012 session of WP.29, but to include some minor editorial corrections transmitted by the expert from ETRTO to the secretariat.
32. The expert from ETRTO recalled the purpose of GRRF-71-11 justifying the insertion of provisions for snow tyres of class C2 (ECE/TRANS/WP.29/GRRF/2011/29). GRRF adopted ECE/TRANS/WP.29/GRRF/2011/29 and agreed to submit it to WP.29 and AC.1, for consideration at their November 2012 sessions, as part (para. 25 above) of draft Supplement 2 to the 02 series of amendments to Regulation No. 117, subject to a final review by GRB and GRRF at their next sessions in September 2012.
33. The expert from France introduced ECE/TRANS/WP.29/GRRF/2012/5 proposing to amend the definition of the measuring rim for C1, C2 and C3 tyres. Following the discussion, the expert from France presented a revised proposal (GRRF-72-24) taking into account the comments received. GRRF adopted ECE/TRANS/WP.29/GRRF/2012/5 as reproduced in Annex VII and agreed to submit it to WP.29 and AC.1, for consideration at their November 2012 sessions, as a separate document for draft Supplement 2 to the 02 series of Amendments to Regulation No. 117, also subject to a final review by GRB and GRRF at their next sessions in September 2012.
34. The expert from ETRTO proposed to clarify the title of Regulation No. 117 and its Annex 1 (ECE/TRANS/WP.29/GRRF/2012/10). GRRF adopted the proposal and it was agreed to have a final review by GRB and GRRF at their next sessions in September 2012. The secretariat was requested to submit it to WP.29 and AC.1, for consideration at their November 2012 sessions, as part (paras. 25 and 32 above) of draft Supplement 2 to the 02 series of amendments to Regulation No. 117.
Documents AMEVSC-06-012e (Annex 21 Appendix 1 – use), AMEVSC-06-13e (Annex 21 Appendix 2 – validation) and AMEVSC-06-14e (Annex 21 Appendix 3 – test report) were reviewed and further refined with the results given in the documents AMEVSC-07-07e, AMEVSC-07-08e and AMEVSE-07-09e respectively.
The secretary was asked to consolidate the 3 documents in to a single document, add the justification and send it to GRRF for consideration at its February 2012 session as Supplement 10 to the 11 Series.
Note: ECE/TRANS/WP.29/GRRF/2012/2 is the resulting document.
Using AMEVSC-08-05e as a basis and taking into account the comments in AMEVSC-08-10e, the proposal tabled at the 72nd GRRF (GRRF/2012/2 (AMEVSC-07-10e)) was review paragraph-by-paragraph and point-by-point.
The results of this review are given in document AMEVSC-08-11e with the major amendments being:
► Appendix 1 paragraph 1.3.
► Appendix 2 paragraph 1.1. – all listed parameters divided into 2 types and placed in 2 new sub-paragraphs 1.1.1. and 1.1.2.
► Appendix 2 paragraph 1.4.2.
► Appendix 3
The proposed new paragraph 2.5.1. to Appendix 2 – document AMEVSC-08-09e – was discussed, with the result being shown in document AMEVSC-08-12e and the clean text taken into AMEVSC-08-11e.
► Similar idea to Annex 11 Appendix 2 paragraph 1.2.1.
► Part of the appendix and not a transitional provision with specific dates, as it will be a supplement
11. The expert from OICA introduced a proposal for editorial corrections to Regulation No. 13 (GRRF-73-02). GRRF agreed to two of the three proposed changes and adopted the proposal as reproduced in Annex 3 to this report. The secretariat was requested to submit it to WP.29 and AC.1 for consideration at their March 2013 session as Corrigendum 2 to UN Regulation No. 13.
12. GRRF noted the state of discussions in WP.29 on dynamic or static references to other UN Regulations and private standards. GRRF welcomed the recommendation to proceed on a case by case approach. The expert from Japan introduced a proposal to insert in Regulations Nos. 13 and 13-H a reference to Regulation No. 10 and its 04 series of amendments. The experts from OICA and CLEPA proposed to make a reference to the 03 series, as the 04 series only defines new requirements for hybrid electric vehicles (HEV) and electric vehicles (EV) vehicles. OICA recalled the purpose of ECE/TRANS/WP29/GRRF/2011/34 and especially the justification part. GRRF agreed to resume the discussion at its next session. For this purpose, the Chair requested the secretariat to distribute GRRF-73-14 with an official symbol, to keep ECE/TRANS/GRRF/2012/21 and to reinsert ECE/TRANS/GRRF/2011/34 on the agenda.
13. The expert from Belgium recalled the work progress (GRRF-73-09) made by the informal group on AMEVSC proposing updated provisions of Annex 21 (and its appendix) to UN Regulation No. 13 dealing with the use of simulation tools duly validated to prove compliance of the vehicle stability function (ECE/TRANS/WP.29/GRRF/2012/2). The Secretary introduced GRRF-73-06. GRRF was supportive of the proposal but raised some detailed issues. The Chair invited GRRF to provide the Secretary of the informal group with written comments to allow a revision to be prepared as an official document for consideration by GRRF at its next session .
14. The Chair recalled the purpose of ECE/TRANS/WP.29/GRRF/2012/11 and GRRF-72-28 on the introduction of an electro-hydraulic transmission for electrical brake systems.
