2. Advanced Emergency Braking Systems

6. The expert from OICA, recalling its presentation at the seventy-eighth session of GRRF and the proposed alternatives proposed e.g. in GRRF-78-30 to explore possibilities of exemption for specific vehicle applications (e.g. off-road vehicles), sought for guidance on how to proceed. He explained that with the given texts of Regulations No. 130 and 131, vehicles not benefiting from Advanced Emergency Braking Systems (AEBS) or Lane Departure Warning Systems (LDWS) get individual single approvals, which is costly and time consuming. The expert from FEM explained that in their views mobile cranes vehicles should not be equipped with AEBS or LDWS.

GRRF-78-30 | Introduction of OICA proposal on AEBS-LDWS regulations Explanation of OICA's requests to exempt certain vehicles from mandatory AEBS and/or LDWS requirements due to their uses and the technical limitations of these systems. For example, the sensors used by the systems cannot operate reliably on certain special purpose equipment (such as snow plows) where the equipment and the nature of the operating environment are prohibitive.

7. GRRF preferred the proposed option to amend the introduction of Regulations Nos. 130 and 131, providing useful information to Contracting Parties applying these Regulations.

The Chair informed that he would present the draft ToR to WP 29 in June 2015 but requested that at their first meeting the informal group should refine the ToR in line with comments received. The Chair also suggested that the timing suggested was very ambitious and recommended to the group that the plan of work should be extended to a more realistic date.

GRRF-79-23 | Proposal to establish an informal working group on Automatically Commanded Steering Function Proposal to develop regulatory provisions that would enable the approval of automated steering systems (i.e., systems that control vehicle lateral movement) that operate at speeds higher than 10 km/h. The proposal originates from discussions on lane-keeping assistance systems and on automated driving.
10. International Whole Vehicle Type Approval (IWVTA)
10. (a) Report on the IWTVA informal group and sub-group activities

43. The GRSG Ambassador, on behalf of the GRRF Ambassador, presented GRRF-79-37 and reported on the activities of the IWG on IWVTA and its subgroups. GRRF noted that IWVTA was one of the main objectives associated with Revision 3 of the 1958 Agreement which was expected to enter into force in March 2016 if no adoption delay would occur. He recalled that the GRRF actions related to IWVTA should ideally be completed by February 2015.

GRRF-79-37 | Update for GRRF on the status of the International Whole Vehicle Type Approval project
10. (b) Regulation on tyre installation

44. The expert from OICA presented GRRF-79-08, superseding ECE/TRANS/WP.29/GRRF/2014/13 on the tyre installation for M1 vehicles. The proposal received some editorial comments. GRRF agreed to revisit this item at its September 2015 session on the basis of a revised proposal by OICA.

GRRF-79-08 | Proposal to amend the draft new regulation on tyre installation A new regulation on tire installation has been prepared for use within the International Whole Vehicle Type Approval system. Pursuant to discussions among stakeholders, this proposal amends the scope of the draft regulation (especially in order to avoid redundant approval requirements across regulations) and clarifies the run-flat tyre requirements.
10. (c) Regulation No. 13-H

45. The expert from OICA introduced GRRF-79-05, GRRF-79-06 and GRRF 79 07 superseding official proposals for separate Regulations on Brake Assist Systems (BAS) (ECE/TRANS/WP.29/GRRF/2014/11) and on Electronic Stability Control (ESC) (ECE/TRANS/WP.29/GRRF/2014/12) extracted from Regulation No. 13 H (ECE/TRANS/WP.29/GRRF/2014/10). GRRF agreed that further work e.g. on the transitional provisions, was necessary to make sure that Countries mandating the fitment of ESC or BAS on the basis of the existing text of Regulation No. 13-H would be able to continue to mandate this fitment, unaffected by this extraction. The expert from UK agreed to lead an ad-hoc group of interested members on addressing the transitional provisions, to establish a methodology for all of the regulations that would need to be separated for IWVTA. GRRF agreed to reconsider this proposal at its September 2015 session.

GRRF-79-05 | Revised proposal to delete ESC and BAS provisions from UN R13-H New proposal to delete provisions for electronic stability and brake-assist systems from UN R13-H as part of their transposition into new stand-alone regulations. This proposal supersedes document GRRF/2014/10.
GRRF-79-05/Rev.1 | Proposal to remove ESC and BAS provisions from UN Regulation 13-H New proposal to delete provisions for electronic stability and brake-assist systems from UN R13-H as part of their transposition into new stand-alone regulations. This proposal supersedes document GRRF/2014/10.
GRRF-79-05/Rev.2 | Proposal to remove ESC and BAS provisions from UN Regulation 13-H Updated proposal to delete provisions for electronic stability and brake-assist systems from UN R13-H as part of their transposition into new stand-alone regulations. This proposal supersedes document GRRF/2014/10.
GRRF-79-06 | Proposal to amend the draft new regulation on brake-assist systems Amendments to clarify and improve the text of the new regulation that would remove BAS provisions from UN R13-H.
GRRF-79-07 | Proposal to amend the draft new regulation on electronic stability controls Clarifications and improvements to the draft new regulation that removes ESC provisions from UN R13-H, including deletion of the "complex electronic systems" (CEL) annex and replacement with reference to compliance with the relevant safety provisions of UN R13-H.
10. (d) Regulation No. 64 and Tyre Pressure Monitoring System (TPMS)

46. The expert from OICA introduced ECE/TRANS/WP.29/GRRF/2015/12 as amended by GRRF-79-09 and ECE/TRANS/WP.29/GRRF/2015/13 as amended by GRRF-79-10 proposing a separate Regulation dedicated to Tyre Pressure Monitoring System (TPMS) and removing the provisions related to TPMS of Regulation No. 64. The expert from the Russian Federation presented GRRF-79-20-Rev.1 containing an alternative proposal for the drafted transitional provisions in GRRF-79-09. GRRF agreed to revisit this item at its September 2015 session on the basis of a revised proposal.

GRRF-79-09 | Proposal for amendments to UN Regulation No. 64 Proposal to remove tire-pressure monitoring provisions from UN R64 to enable the use of UN R64 within the International Whole Vehicle Type Approval system.
GRRF-79-10 | Proposal for a Regulation on Tyre Pressure Monitoring Systems Revised text proposing a stand-alone TPMS regulation based upon the provisions currently in UN R64.
GRRF-79-20/Rev.1 | Comments on the transitional provisions to Regulation No. 64 This document represents the result of analysis of the existing (document GRRF/2015/12) and newly introduced (GRRF-79-09) transitional provisions concerning the separation of tire-pressure monitoring systems from UN R64.
GRRF/2015/12 | Proposal for an amendment to Regulation No. 64 Proposal to separate provisions for tire-pressure monitoring systems from UN R64.
GRRF/2015/13 | Proposal for a separate regulation on tire-pressure monitoring systems based on Regulation No. 64 Proposed text for a new UN Regulation that would comprise all the tyre-pressure monitoring system (TPMS) provisions presently contained in UN Regulation No. 64. This separation is proposed to facilitate the use of UN R64 in the international whole vehicle type approval system under development.
