Note by the GRVA secretariat on subjects under consideration by GRVA.

Text of the Regulation up to and including 12 series of amendments (Date of entry into force: 8 October 2022).

Proposal to clarify the text in response to questions raised concerning endurance brakes for vehicles utilising regenerative braking systems.

This document amends the formal proposal in document GRVA/2023/9.

Information on deliberations concerning communication protocols between electric vehicles and recharging infrastructure (in a similar way as done for the request to address V2V communication).

Proposal for editorial improvements for clarity and consistency across regulations.

Proposal to clarify the application of the proposed changes with regard to electro-mechanical braking.

Proposal to clarify that EMC covers ALKS in activated and deactivated state.

Proposal to establish an expert group to develop amendments to UN R13 and R13-H that would permit the introduction of braking systems using electric control transmission and electric energy transmission.

Proposal to facilitate effective functioning of the LDWS fitted to Australian supplied vehicles of category M₂, M₃, N₂ and N₃ primarily used under highway conditions.

Proposal to include the option to use a QR code (or another type of digital data carrier) to replace, in case of necessity, some packaging information.

Proposal from the GRE task force on Autonomous Vehicle Signalling Requirements to amend the Regulation to enable its application to vehicles equipped with driver support and Automated Driving Systems.

Proposal to permit crossing of lane markings by ACSF of category B1 to assist the driver in forming an access corridor for emergency and enforcement vehicles in slow-moving traffic (based on provisions adopted for UN R157).

Proposal to clarify the provisions for ACSF Cat. A “Remote Controlled Parking (RCP)” for vehicle combinations. The current definition for RCP S_RCPmax sets a maximum limit of 6m distance to the motor vehicle, which is insufficient in situations where the operation is supervised by the driver located behind the vehicle combination.

Proposal to include the option of using a QR code (or another type of digital data carrier) to replace the paper fitting instructions physically included in the packaging.

Proposal to include the option of using a QR code (or another type of digital data carrier) in place of the paper fitting instructions physically included in the packaging.

Proposal to include the option of using a QR code (or another type of digital data carrier) in place of the paper fitting instructions physically included in the packaging.

Proposal to clarify the packaging and labelling requirements for some types of brake lining assemblies, which could be fitted on various different applications and to allow the option of using a QR code (or another type of digital data carrier) to replace some information printed on or included in the packaging.

Proposal to clarify the packaging and labelling requirements for some types of brake lining assemblies, which could be fitted for various different applications and to allow the option of using a QR code (or another type of digital data carrier) to replace some information printed on or included in the packaging.

Proposal for amendments to Annex 18 regarding special requirements for electronic control systems and for related transitional provisions for its entry into force.

Proposal to add the text, "In case that saturation of the front tyres happens before the above calculated magnitude angle, this angle may be used as the final steering amplitude, but only if this angle is greater or equal to 6.5 A.” based on the following justification:

1. Reaching fixed amplitude, i.e., fixed steering wheel angular speed due to given 0.7 Hz sine frequency, needs much more torque with quick steering gear ratio systems than with slow steering gear ratio systems, and produces much more wheel steer.
2. Car behavior (yaw rate, lateral acceleration and thus trajectory) is similar for all amplitudes above approx. 7 to 8 A (i.e., more than 7 times the steering wheel angle corresponding to 0.3 g), because front tires are saturated. More steer of the tires doesn’t provide more lateral force, so yaw rate and lateral acceleration don’t increase. Continuing to increase steering wheel amplitude after front tire saturation doesn’t give more information.
3. There might appear in the future some vehicles which have significantly low steering gear ratio (i.e., quick steering characteristics) and may need too much steering wheel torque to achieve the 270 degrees sine amplitude at 0.7 Hz (not reachable by conventional steering robots), then jeopardizing the easy approval of future beneficial steering equipment e.g. steering-by-wire systems.

Proposal to align the text with the guidelines on UN regulatory procedures and transitional provisions in UN Regulations (document ECE/TRANS/WP.29/1044/Rev.3). Under the guidelines, a UN Regulation (in this case, UN R157) making reference to the provisions of another UN Regulation (in this case, UN R10) shall not require actual approval to that UN regulation but simply refer to the provisions of that UN Regulation.
