Presentation highlighting the growing use of carbon-ceramic (CSiC) brake discs and the need to address these products under UN R90 given that the replacement discs regulation is founded upon conventional cast iron technologies.

Updated version of the proposal to remove tables specifying general values for replacement discs and drums that are identical to the original (2.3.3.4) since such replacements must by definition have values identical to the corresponding original parts. The proposal also would change the maximum permitted thickness variation of discs for medium and heavy vehicles from 0.030 mm to 0.050 mm (the common OEM specification). This revised proposal clarifies that the proposal would revise the specifications for vehicles of categories M3, N3, O3 and O4 but retain the maximum permitted specification of 0.030mm for vehicles of categories M2 and N2.

OICA and CLEPA note that the current work on ACSF does not address class O vehicles (trailers) and therefore leaves unsettled the issue of heavy-duty commercial vehicles. The two groups signal that the informal group must coordinate with the GRRF to ensure that trailers are eventually incorporated in the ACSF approval procedures under UN R79.

UN R13 allows for the exemption of certain vehicles from the requirement for electronic stability controls. This proposal seeks to clarify the scope of the exemptions to include any special purpose vehicle with a non-standard chassis. The change was prompted by a modified vehicle where use of ESC was not feasible, but where the current UN R13 language left doubt as to whether the ESC requirement was applicable.

Revised version of the proposal to remove tables specifying general values for replacement discs and drums that are identical to the original (2.3.3.4), taking into account comments received during the February 2016 GRRF session. The tables are considered superfluous since replacement parts identical to the original parts must by definition have values identical to the corresponding original parts. This proposal also would change the maximum permitted thickness variation of discs for medium and heavy vehicles from 0.030 mm to 0.040 mm (the common OEM specification). This has been changed from the previous proposal of 0.050 mm. This revised proposal clarifies that the proposal would revise the specifications for vehicles of categories M3, N3, O3 and O4 but retain the maximum permitted specification of 0.030mm for vehicles of categories M2 and N2.

The previous GRRF session considered a proposal to add a trigger threshold requirement and to modify the sampling rate, deceleration limit and data selection criteria for category B brake-assist systems. CLEPA has provided this presentation to clarify the background behind the BAS provisions and facilitate further discussion.

Reproduction of the proposal submitted to GRSG in order to clarify the intended scope of the regulation and to align the drop ball test language with that of UN Regulation No. 43 and ISO ISO 3537.

Proposal to require the installation of a message routing function (per ISO 11992) on trailers that are:

• equipped with more than one brake electronic control unit,
• equipped with an electric control, and
• towing a trailer.

Proposal to amend the toxicity and flammability declarations via references to EN71 (European safety standards), taking into account procedures of FMVSS 302.

Proposal to amend the toxicity and flammability declarations via references to EN71 (European safety standards).

Proposal to amend the toxicity and flammability provisions. This proposal runs in parallel with the proposal for Supplement 5 to the 00 series of amendments (document GRSP/2016/5).

Proposal to to clarify the provisions for dynamic testing of rear seat system, advanced restraint system approval and transitional provisions prepared by the European Association of Automotive Suppliers (CLEPA) in cooperation with France, Germany, Japan, the Netherlands and the International Organization of Motor Vehicle Manufacturers (OICA). This proposal supersedes GRSP/2015/18 and GRSP-58-35.

Discussion of parameters to delineate corrective steering function (CSF) from automatically commanded steering function (ACSF) systems. The former refers to intermittent systems such as lane-keeping while the latter refers to systems in continuous control of the steering function.

Presentation and supporting materials to facilitate discussion towards clarifying provisions on sensor range and monitoring of the vehicle environment.

Comments on the working draft of 9 March 2016.

Amendment to the proposals (GRSP/2016/3, GRSP/2016/5, and GRSP/2016/6) to amend the toxicity and flammability declarations via references to EN 71 (European safety standards), taking into account procedures of FMVSS 302. The amendments propose the burning rate values of FMVSS 302 (302.4 inches/102 mm per minute), to harmonize the three proposals with regard to EN standards references, and to incorporate the amendment 1 to EN 71-3 (A1:2014).

Comments on document EPPR-16-20/Rev.1.

Proposal for amendments to document ACSF-07-02.

Industry comment in support of “Option 4” in document GRRF/2016/45, the proposal to introduce technical requirements for Corrective Steering Functions (lane departure prevention, lane-keeping assistance (LKAS), steering angle correction, etc.) as defined in the regulation.

Proposed changes to the draft amendments to UN R79 concerning ACSF B1 systems. The proposed new wording for the triggering condition of the warning (“any front tyre of the vehicle is crossing the lane marking”) is technically more specific than the original (“the vehicle is going to leave the lane”). The use of a haptic signal as an alternative to the acoustic signal achieves the goal pursued by Germany. This proposal is consistent with the warning strategy of AEBS specified in UN R131. In the case of M2 M3 N2 N3 vehicle categories, it is proposed to take as a base the requirements specified in UN R130 LDWS regulation, which achieves the goal.

Proposal to replace the current Figure 2a with a more accurate drawing reflecting the meaning of paragraph 2.4.2.2 of the regulation. The new drawing addresses the lateral limits of any opaque obscuration of the window area.

Proposal to amend document WP.29/2016/98. The proposal clarifies the subject of paragraph 12.1 and corrects an editorial error concerning the repetition of footnote 2 that exists already in Annex 1B to Regulation 16.

Analysis raising concerns regarding the proposal to establish photometric requirements for Class B1 based on average real performance of present Class B (halogen/LED) without reference to design specifications such as the luminous flux of light source.

Proposal for an “Emergency Steering Function” to automatically assist drivers in avoiding an impending collision with an obstacle or other vehicle.

Proposal to include under the complex electronics annex of UN R79, if only as an interim measure, provisions for the approval of automated systems that bring a vehicle safely to a stop in the event of driver incapacitation.

Proposals to clarify and refine provisions in the draft corrective steering function amendment to UN R79 (document GRRF-82-12/Rev.3).

Proposals for the text of the draft amendment to UN R79 to enable the approval of automated lane-changing systems.

Proposal to amend provisions on electronic stability control warnings under braking regulations to allow for activation of the ESC visual warning during a stability-assistance intervention of an electronic steering control. The aim is to avoid separate requirements for brake-actuated and steering-actuated stability assistance that would lead to two visual warnings where only one is appropriate.

Proposal for amendments relating to the approval of Enhanced Child Restraint Systems that feature an impact shield.
