Proposal to clarify EMC requirements: "The effectiveness of the system shall not be adversely affected by magnetic or electrical fields. This shall be demonstrated by fulfilling the technical requirements and respecting the transitional provisions of 07 or later series of amendments to UN Regulation No. 10.” This proposal supersedes document GRVA/2024/3.

Proposal to clarify requirements in the scope requesting for reciprocal recognition with UN Regulation No. 152 (Advanced Emergency Braking System (AEBS) for M1 and N1 vehicles).

Proposal for a supplement to the 02 series of amendments to UN Regulation No. 152 (Advanced Emergency Braking System (AEBS) for M₁ and N₁ vehicles), based on informal document WP.29-191-23. Amend Section 1. Scope to clarify that this Regulation applies to vehicles of category M₁ or N₁, and at the request of the manufacturer, vehicles of categories M₂ and M₃ and N₂ with a maximum mass not exceeding 8,000 kg equipped with hydraulic brakes may be approved under this Regulation, where equipped with an on-board system to avoid or mitigate the severity of a rear-end in-lane collision with a passenger car, avoid or mitigate the severity of an impact with a pedestrian, and avoid or mitigate the severity of an impact with a bicycle.

Proposal to insert para. 5.2.6.5.1.1. to provide that the activated system of vehicles of categories N₃ or M₃ shall only initiate a regular lane change if the permitted maximum speed on the target lane is limited for all vehicle categories. The justification states that regular lane changes of heavy vehicles shall only be allowed into target lanes where a speed limit applies because lane changes of heavy vehicles into not speed restricted lanes can establish a serious safety threat to approaching vehicles due to high speed differences.

Proposal to permit the type approval of a park lock device as an alternative to the friction parking brake(s).

Proposal to permit the type approval of a park lock device as an alternative to the friction parking brake(s).

Proposal to explicitly note objectives behind provisions requiring manufacturers to perform in-service monitoring and reporting (ISMR) for their driver-control assistance systems approved under UN R171 and for UN R171 to be continually reviewed based on technological progress and data collected via ISMR.

Proposal to establish a UN Regulation based on EU Regulation 2021/646 to address collisions involving unintentional lane departures. An ELKS is defined as a system combining a lane departure warning system (LDWS) and a corrective directional control function (CDCF).

Proposal to permit the use of virtual testing as an alternative to physical testing.

Proposal to permit the use of virtual testing as an alternative to physical testing.

Proposal to permit the use of virtual testing as an alternative to physical testing.

Proposal for amendments to the draft provisions on e-trailers.

Draft document under preparation by the task force on Vehicular Communications.

Proposal to align the original proposal to amend UN R171 with UN R79 and UN R157 with regard to the use of the term “activation” in relation to the powertrain.

Proposal to address loss of trailer friction braking efficiency due to increased use of robust endurance braking systems and electrification of trucks. The number of trucks with strong endurance braking systems and increasing electrification of vehicles with more efficient energy recuperating systems reduces the use of friction brakes. As a result, brake pads and linings in some commercial vehicles do not reach a temperature that is needed for the development of optimum brake performance. In particular in trailers, a loss of brake force develops due to brake pads and linings losing effectiveness – they “fall asleep” and need to be replaced although they are not worn out.

Proposal to resolve an inconsistency in wording across the series with regard to the parking brake performance requirement.

Proposal to improve the wording of the “decelerating lead vehicle” test scenario for consistency with related provisions in the text.

Proposal to modify the track and real-world testing provisions in Annex 6.

Proposal to update the text in line with the establishment of UN R171 on DCAS.
