Proposal to amend provisions in documents GRVA/2025/13 and GRVA/2025/14 concerning the type approval of a park lock device as an alternative to or in combination with the friction parking braking.

Proposal to resolve the problem of decreasing trailer brake performance caused by brake pads and linings “falling asleep”.

Proposal to solve the issue of atypical glass fracture.

Proposals to resolve inconsistencies, improve the text, and correct editorial errors found in the 07 series.

This proposal intends to establish a definition for ‘Hydrogen ICE vehicle’ and the related method for ‘trip validation’

This proposal removes rebound head contact from the head acceleration requirement for all CRS.

Proposed modifications to ECE/TRANS/WP.29/GRSP/2025/7

Proposal to clarify that an Emergency Stop Signal may be generated by application of the service braking system via the Electronic Parking Brake.

Proposal to improve usability, especially in enabling user targeting of the stopping point of the vehicle.

Proposal to clarify that the use of any braking system control for testing the effectiveness of the secondary braking system in failure conditions is allowed.

Proposal to add definitions for “e-axle”, “e-axle trailer”, and “dynamo function” for trailers of category O₃ and O₄, amend paragraph 2.2.2.4. to reference electric regenerative braking systems and electric propulsion systems, insert new paragraphs 5.2.2.26.1. through 5.2.2.26.5. establishing special requirements for dynamo function including maximum retardation power of 20kW, wheel locking prevention at speeds above 15 km/h, and assessment according to Annex 18, insert requirements in Annex 4 to switch off electric regenerative braking systems and dynamo function during brake applications and tests, and amend Annex 19 Appendices 5 and 7 to include e-Axles in schematic diagram considerations. This document is based on GRVA/2025/15 and GRVA-21-12.

Proposal to allow the driver to slow down the remote parking manoeuvre, including coming to a stop, earlier than intended by the system.

Proposal to clarify the text for consistency, including replacement of the wording “torso line” by “median longitudinal plane of the seat” and to align the text with GTR 7 concerning the determination of whether a seat includes a head restraint that must comply with the requirements of this regulation.

Proposal to establish definitions for “e-axle”, “e-axle trailer” and “dynamo function” and to establish provisions for the approval of e-axle trailers with regard to their “dynamo function”.

Proposal from OICA, CLEPA, and CITA to amend CITA’s proposal to enable real-time reading of electrical transmission brake demand values via an electronic vehicle interface and an off-board electronic device during periodical technical inspections, including a 24-month transitional period.

This document proposes amendments to UN Regulation 13 for trailers with dynamo function, superseding GRVA-22-26, GRVA-2025-15, and GRVA-21-12. The dynamo function converts vehicle kinetic energy into electrical energy without affecting braking system forces and is limited to trailers of category O₂, O₃, and O₄ pending further development. Maximum retardation power limits are 22 kW for O₃/O₄ trailers and 2 kW for O₂ trailers, measured using specified methods. Requirements include wheel locking prevention with braking rate not exceeding 0.04 per wheel, functional safety assessment per Annex 18, and demonstration that anti-lock and stability control systems comply when dynamo function is enabled. The dynamo function shall not be used during brake application testing. Administrative amendments update Annexes 2, 4, 5, 10, 19, 20, and 21 to reference e-axles and dynamo functions.

This document aims at transposing UN GTR 24 into a new UN Regulation on uniform provisions concerning the approval of non-original and identical replacement brake parts with regards to particle emissions.

Proposal to exempt CSF and ESC from prohibition on use of Advanced Driver Assistance Steering Systems while an ADS feature is active.

Proposal for amendments to the 05 series of UN R79 to enable the type approval of ADS vehicles, including those without manual controls.

Proposal aims to correct and clarify the text of the regulation, and to modify the current wording which creates misunderstandings and a non-harmonized application of the regulation by technical services. proposal for supplement 1 to the 10 series of amendments, supplement 2 to the 11 series of amendments and supplement 1 to the 12 series of amendments
