Proposal to require automatic deactivation of AEBS upon activation of an ADS feature and automatic reactivation upon deactivation of an ADS feature.

Proposal to require automatic deactivation of AEBS upon activation of an ADS feature and automatic reactivation upon deactivation of an ADS feature.

Proposal to amend the scope to specify that UN R157 would not apply to an ALKS approved as an ADS feature under the forthcoming regulation on Automated Driving Systems.

UN R13 and UN R78 establish different brake system requirements for 4-wheel vehicles. R13H requires split service brake systems with front/rear proportioning; R78 permits split service brake systems, combined brake systems, or two separate service brake systems without proportioning requirements. Type-O dry braking tests differ: R13H requires engine disconnected at 100 km/h with stopping distance 0.1v + 0.0060 v² and MFDD 6.43 m/s²; R78 specifies multiple tests at 40, 60, and 100 km/h with varying requirements. Type-I brake fade tests use different snub protocols and performance thresholds. Secondary braking failure criteria differ at specified speeds. R78 requires wet brake testing, a 30 km/h dynamic park brake test with 18% gradient and 5 minutes hold time; R13H specifies static gradient tests. R78 includes detailed ABS, functional safety, and regenerative braking requirements; R13H does not.

The document addresses consistency issues across multiple UN Regulations (R26, R28, R29, R34, R35, R39, R43, R45, R46, R48, R49, R134, R135, R137, R138, R141, R142, R143, R144) concerning automated driving systems. It proposes improved wording for fuel leakage provisions, foot control applicability for vehicles of category M₁, and speedometer requirements when ADS features are active. The document recommends removing duplicate definitions of ADS, DDT, bi-directional vehicle, and forward direction across regulations. It raises questions regarding application to category Y vehicles, handling of bi-directional traffic equipped vehicles, and whether requirements should apply to vehicle users or only when ADS features are active.

Proposal to update noise test-track requirements from ISO 19844:1994 to ISO 10844:2011 and incorporates transitional provisions to allow repaving of existing, non-compliant test tracks with the ISO 10844:2011 standards. This supersedes document GRB/2012/9.

Proposal to amend document GRBP/2024/21

Proposal to amend the provisions for a pause function for reversing warning systems with the aim to comply with the national environmental (noise) restrictions.

Proposal to clarify the requirements for non-original replacement exhaust silencing systems (NORESS).

Text prepared by the Netherlands and the United Kingdom in response to the proposal (document GRE/2013/13) from France and Germany to implement direction indicator lamps with a variable apparent surface into UN Regulation No. 6.

Text prepared by the Netherlands and the United Kingdom in response to the proposal (document GRE/2013/14) from France and Germany to implement provisions concerning direction indicator lamps with spatial variation of the intensity within UN Regulation No. 48.

UK proposal to address concerns raised in the series of proposals to insert provisions for the use of incandescent light sources in the case of light source modules and lamps with non-replaceable light sources.

Proposal aims to enhance the conspicuity of motorcycles equipped with a front position lamp reciprocally incorporated with a direction indicator, by clarifying the electrical connection requirements

Proposal to introduce a requirement for minimum separation distance of optional side-marker lamps fitted to the sides of M₁, N₁, O₁, and O₂ vehicle to avoid the possible proliferation of flashing lamps fitted to smaller vehicles.
