While encouraged by the adoption of a uniform minimum sound alert standard, the WBU continues to believe that: 1) the proposed minimum sound standard is too low for safety; 2) the AVAS should remain on while the QRTV is active but stationary; and 3) the regulation should prohibit manufacturers from providing a means of pausing the alert sound.

Proposal from Turkey to establish requirements for audible systems to alert other road users when a vehicle is operating in reverse.

Explanation of recommendations developed for the European Commission by LAT, TNO, Heinz Steven, and TÜV Nord for the improvement of the regulations with regard to additional sound emission provisions.

Proposal to specify that conditioning of a silencing system is necessary only in cases where exhaust gases come into contact with silencer fibrous materials.

Proposal to clarify that conditioning of a silencing system is necessary only in cases where exhaust gases come into contact with silencer fibrous materials.

Proposal to clarify the test procedure by explicitly excluding first gear where possible from the ASEP control range and to clarify that conditioning of a silencing system is necessary only in cases where exhaust gases come into contact with silencer fibrous materials.

Proposal to clarify that conditioning of a silencing system is necessary only in cases where exhaust gases come into contact with silencer fibrous materials.

Proposal to:
a) Align definitions and content with the other tyre regulations (UN Regulations Nos. 30, 54, 75 etc.);
b) Include a definition of “manufacturer” extracted from the resolution “R.E.3”;
c) Adopt a common definition and use of the terms “Manufacturer’s name”, “Brand name”, “Trademark”, “Trade description” and “Commercial name” and their links; and
d) Add information in the certificate to enable approval authorities to more easily understand the products the certificate addresses.

Presentation of issues raised during discussions of the GRE Task Force on EMC requirements with regard to the application of several UN Regulations to trolley buses depending upon their configuration (e.g., dual-mode operation either connected to overhead cables or in standard bus mode).

Proposal to prohibit the use of a pause function for the acoustic vehicle alert system.

Proposal to update and clarify the regulation. The proposal refines definitions, removes the “AWD” abbeviation for “audible warning device” to avoid confusion with its more common use for “all wheel drive”, adds T category agricultural vehicles to the scope, modifies some administrative communications, and proposes three-direction acoustic measurements. The proposal also aims to structure the regulation to enable its application to additional sound warning devices not presently regulated at the international level, excluding acoustic vehicle alerting systems (AVAS) which will be subject to a separate regulation on minimum vehicle sound levels.

Based on the outcomes of a European Commission study, proposal to clarify the text and align its provisions with other vehicle sound regulations, especially UN R41.

Proposal to update the provisions of Regulation No. 92 to a level at least equivalent to the corresponding provisions in the European Union legislation. The document proposes improved terminology and definitions, including new ones, improved sound emission testing conditions and procedures. It also introduces anti-tampering provisions and an “Additional sound emission provisions” (ASEP) statement by the manufacturer.

Proposal to clarify the regulation with regard to propulsion of the vehicle (replace the term “travel”), definition of the “pause function” (including taking into account the Japanese proposal to prohibit the use of a pause function), and provisions for deactivating AVAS coding in accordance with local market requirements and under conditions outside the scope of the regulation.

Based on the outcomes of a European Commission study, proposal to clarify the text and align its provisions with other vehicle sound regulations, especially UN R41, including to replace references to “two wheeled moped” with the term “L1 category vehicles” (and consequently to replace references to “moped” with “vehicle”) and to replace the term “noise” with “sound” (except for references to background noise) throughout the regulation. It proposes improved terminology and definitions, including new ones, improved sound emission testing conditions and procedures. It also introduces sound emission measurement through new testing of in use vehicles in motion.

Proposal to correct the text where the word “tyres” was inadvertently omitted from Paragraph 2.1.

Proposal for editorial improvements to document GRB/2016/4 intended to update and restructure UN R28.

Proposal to update, clarify, and restructure document GRB/2016/4 which aims to refine definitions, remove the “AWD” abbeviation for “audible warning device” to avoid confusion with its more common use for “all wheel drive”, add T category agricultural vehicles to the scope, modify some administrative communications, and add three-direction acoustic measurements. The proposal also aims to structure the regulation to enable its application to additional sound warning devices not presently regulated at the international level, excluding acoustic vehicle alerting systems (AVAS) which will be subject to a separate regulation on minimum vehicle sound levels.

Proposal to clarify the text in order to avoid misinterpretation.

Proposal to refine the scope by replacing the phrase “can travel” by “can be propelled”. The use of “travel” in the scope can be interpreted to include vehicles using using electrical systems for purposes other than propulsion (e.g., energy recuperation) that fall outside the test conditions of UN R138. The proposal further amends:

1. Paragraph 2.7. to make clear the “pause function” refers to systems that allow the driver to deactivate an AVAS system;
2. Paragraph 6.2.6.: The vehicle operator shall not deactivate AVAS while driving. However, the manufacturer shall be enabled to activate or deactivate AVAS, including automatically, by regional coding according to legal provisions of various markets.
3. Paragraph 11.: the transitional provisions were added according to the rules of WP.29 for new series of amendments. Paragraph 11.6. has been added to maintain approvals that also comply with the new series of amendments, as is the case for vehicles that do not have a pause function according to the newly suggested paragraph 6.2.6.
4. Annex 1, Addendum to the communication form No …, Technical Information: technical information regarding “Pause switch (yes/no)” will be no longer necessary.
