Proposal to amend para. 6.1.10. to address division by zero cases when an OVC-HEV consumes zero fuel under charge-depleting conditions by applying good engineering judgement, and amend Annex B8, para. 4.2.2. to modify the charge-depleting fuel efficiency calculation formula for OVC-HEVs and OVC-FCHVs under Level 1B, incorporating treatment of zero fuel consumption cases. The amendments prevent invalid calculations and ensure robustness of WLTP-based methods, addressing limitations in exhaust gas analysis equipment that cause cycle “n” to contain mixed Charge Depleting and Charge Sustaining operation.

OICA-proposed amendments to the draft regulation on tire-pressure monitoring systems.

OICA-proposed corrections to the draft regulation on tire-pressure monitoring systems.

OICA position on the draft proposal for a regulation on tire-pressure monitoring systems.

This document addresses the ramifications of introducing the proposals outlined in GRRF-72-07 (superceded by GRRF-72-07/Rev.1) specifically associated with semi-trailers.

Denmark submitted document GRRF-71-19 (subsequently integrated into GRRF/2012/12) proposing to narrow the compatibility bands for control line pressure versus brake rate. This document challenges the proposed changes as effectively mandating electronic braking and imposing unwarranted costs.

Denmark submitted Document GRRF-71-18 (subsequently integrated into GRRF/2012/12) proposing to narrow the limits for coupling force control systems which are allowed to override the compatibility bands. This document argues against the proposed changes.

Denmark submitted GRRF-71-19 (subsequently in GRRF/2012/12) proposing a new paragraph to require a test point between the coupling head and the trailer relay emergency valve. This document argues that the requirement is already implicit within UN R13 and therefore, that the change is unnecessary.

OICA proposes alternate language for amendments to the text of Annex 21 governing the use of simulation tools for evaluating electronic vehicle stability control systems (EVSC).

Modified version of document GRRF/2011/35/Rev.1, pursuant to GRRF session 72 discussions, which aims to clarify reasonable levels of braking performance to be expected in different positions of the ignition key (i.e., off, on, lock, etc.).

Editorial corrections to Annex 12 of the Regulation, adding the missing paragraph number 10.3.1.1., moving the formula under paragraph 10.4. to its correct placement under paragraph 10.3.1.2., changing the reference to “paragraphs 3. to 10.” to read “3. to 9.” under paragraph 6.1.3., item 7.
