Revised proposal to align UN R78 with the provisions for anti-lock braking systems used in other regulations, including specific exemptions for certain off-road vehicles as incorporated in UN Regulation No. 13. The proposal clarifies the limits on the use of any temporary ABS deactivation switch and prohibition against permanent disabling of ABS if fitted on a motorcycle. This revised proposal takes into account comments received during the February 2016 GRRF session.

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.

Technical services have reported difficulties in interpreting the requirements and procedures incorporated in the 02 series of amendments to UN R90. Therefore, this submission proposes a special interest group to consider whether an informal working group may be needed to revised UN 92.02.

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. This revised proposal takes into account comments received during the February 2016 GRRF session.

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.

Review of work towards adapting and/or approving certain UN Regulations for use within the International Whole Vehicle Type Approval regulation.

Working draft under development within the Modular Vehicle Combinations informal group to introduce provisions into UN Regulation No. 13 to specify uniform requirements for towing trailers and motor vehicles which may tow more than one trailer (road train combinations). This proposal is being developed based upon a 2009 draft proposal (document GRRF-66-08) discussed within the GRRF.

Copy of document GRRF-81-14: Presentation on French government views on the approval of automated steering at speeds above 10 km/h under UN Regulation No. 79. The principle recommendation is to restrict amendments to UN R79 to lateral vehicle control as speeds above 10 km/h while setting other work on more advanced capabilities (longitudinal + latitudinal, lane change, passing, etc.) for future separate regulations.

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 from the Working Party on Dangerous Goods to delete paragraph 2.2.1 and 2.3.2 in Annex 5 of Regulation No. 13 permitting the use of an endurance braking system on a trailer to compensate for insufficient performance of the endurance braking system of the motor vehicles. Such systems have been prohibited by WP.15 such that alignment of the vehicle technical requirements is needed.

UK input to confirm basic understanding of the proposed categories of corrective steering and automatically commanded steering functions and to propose requirements under each category.

Proposed changes to the draft amendment to UN R79 on automatically commanded steering functions.

Changes proposed by Germany to the draft ACSF amendment (document ACSF-05-16)

Proposal to include three-wheeled category L vehicles within the scope of ABS testing, to align UN R78 with the provisions for anti-lock braking systems used in other regulations, including specific exemptions for certain off-road vehicles as incorporated in UN Regulation No. 13, and to allow for Emergency Stop Signal (ESS) systems on motorcycles and related vehicles. The proposal also clarifies the limits on the use of any temporary ABS deactivation switch and prohibition against permanent disabling of ABS if fitted on a motorcycle.

Proposal to remove certain design restrictions that impede the application of new technologies, especially related to trailer power steering systems and the use of energy from the towing vehicle, including specification of the connector through which electrical energy is supplied in the proposal. This proposal also replaces references to rear-view mirrors with the term “indirect vision devices” to reflect the addition of camera-monitor systems to UN R46 and clarifies the references to Regulation No. 10 on electromagnetic compatibility requirements.

Proposal for corrections to the text and equations.

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 also clarifies the requirements on electromagnetic compatibility via reference to Regulation No. 10.

Proposal to introduce provisions for the approval of replacement brake discs for L-category (motorcycle and related) vehicles, to remove tables specifying general values for replacement discs and drums that are identical to the original, change the maximum permitted thickness variation of discs for medium and heavy vehicles from 0.030 mm to 0.040 mm, and clarify the text in order to avoid additional administrative and financial costs to the applicant due to misinterpretation of the intent of the text.

Proposal for a new UN Regulation based upon brake-assist system provisions extracted from UN R13-H in order to facilitate work on the international whole vehicle type approval system.
