Proposal to revise para. 5.8.15. in the draft interim guidelines.

Table offering the Japanese position on new limit values for 03 series of amendments to Regulation No.51. The limit values are based on the TNO assessment study and German proposal with sub-categories proposed by Japan based upon a database of noise levels of Japanese vehicles.

Based on informal documents GRB-54-03 and GRB-55-01, Japan proposes noise limit values with some modification of the threshold of sub-categories as a possible basis for reaching a common position.

Proposal to amend the classifications of vehicle type in the consolidated version of the proposal for draft 03 series of amendments to Regulation No. 51.

There are two types of N1 having GVM<2.5t. One is front engine type. The other is a flat front vehicle with the engine under the seat and typical in Asian countries. Japan proposes that the sound limit of the latter type should be considered since the sound characteristics of the vehicles are same as that of the N1 having GVM<2.5t.

Japan opposes the inclusion of specifications for Acoustic Vehicle Alerting Systems (AVAS) as contained within the consolidated proposal for the 03 series of amendments to UN R51 (GRB-58-04). AVAS specifications are actively under development as a new GTR and therefore, Japan cannot accept their definition under UN R51 until the GTR deliberations have been concluded.

Proposal from Japan, pursuant to the discussion of document GRB/2014/8 during the previous GRB session, to correct perceived inconsistencies in time measurement accuracy in annex 6.

Proposal for a 01 series of amendments to the new UN Regulation on quiet road transport vehicles to prohibit the use of a pause function for the alert sound.

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

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.

Proposal for a new working group to develop harmonized technical specifications, test procedures and performance requirements for audible warning systems that signal when a category M₃, N₂, or N₃ vehicle is moving in reverse gear.

Proposal based on Informal document GRB-54-03 submitted by the expert from Germany and on Informal document GRB-55-01 submitted by the expert from Japan, including limit values with some modification of threshold of subcategories, which could be the basis of a common position.

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

Proposal introduces a new definition for taxi tyres and establishes different threshold from other tyres.

Presentation to support ECE/TRANS/WP.29/GRBP/2024/20

TF-VS, RD ASEP IWG for 4 Wheel vehicle and 2 wheel vehicle, TF-AVRS

Proposal to adapt the rolling-sound measurement procedures to accommodate special C2 tyres presenting a section width wider than 200 mm, aspect ratio lower than 55, rim diameter code lower than 15 and without any dual fitting indication (i.e. the front size 175/75R15 LT and the rear size 235/50R14 LT or the front size 175/75R15 LT and the rear size 265/50R14 LT).

Proposal to clarify that the maximum sound pressure requirement at the front plane at standstill condition in reverse shall be equal to the maximum level requirement in motion (defined by the QRTV task force as 75 dB(A) for both standstill and reverse driving).

Proposal to clarify tyre abrasion provisions, including to add an ice temperature range of -5°C to -2°C to the test conditions for ice grip tyres.

Pursuant to the decision to delete the phrase "last column of the table” from paragraph 6.1.6. in Regulation No. 7 following changes to the structure of this table, this proposal would delete the same phrase from paragraph 6.1.2. in Regulation No.6.
