Proposal to clarify the provisions in Annex 3, para. 1.5.3.1. in the case where the batteries have been recharged or replaced with a charged set between the hot performance and recovery procedure such that the linings temperature is no longer at the requisite temperature.

Proposal to introduce requirements for the type approval of Electro-Mechanical Braking (EMB) systems.

Proposal for provisions concerning:

1. B1 lane centering
2. ACSF activation conditions
3. Driver override
4. Clarification of ACSF standby-mode
5. Clarification of “ready-to-intervene"
6. Indication to the driver in case of suppression
7. Clarification of suppression criteria
8. Sensor test before activation.

Proposal to amend Annex 8 (Test requirements for Corrective and Automatically Commanded Steering Functions (ACSF)), paragraph 3.5. (Tests for ACSF of Category C) in order to clarify that enabling of the system as part of the test procedure is only necessary when the system is not yet enabled.

Proposal to permit the manufacturer to specify its own formula for the calculation of s_critical. The current formula does not take the dynamic behaviour of vehicles into account and therefore requires gaps that under some traffic conditions don’t usually occur. Since there are different ways of addressing the dynamic behaviour of the vehicles with regard to the original formula, this proposal would allow the manufacturer to specify its own formula provided the safety principle is maintained.

Proposal to clarify that the AEBS may be automatically deactivated in the event that the electronic stability control system is deactivated.

Proposal by the experts from the Informal Working Group on Advanced Emergency Braking Systems (AEBS) for vehicles of Categories M1 and N1 in order to improve the Appendix 2 Annex 3 for assessing robustness against false reaction, to introduce new provisions for automatic deactivation of AEBS, and to improve the text in other instances.

Proposal by the experts from the Informal Working Group (IWG) on Advanced Emergency Braking Systems (AEBS) for vehicles of Categories M₁ and N₁ to introduce provisions for car-to-bicycle scenario in a single step approach. (Alternatively, the IWG has prepared proposals for a two-step approach to introducing the new requirements. GRVA is therefore requested to make a decision on whether car-to-bicycle should be introduced in a single step or in a two-step approach.)

Proposal by the experts from the Informal Working Group on Advanced Emergency Braking Systems (AEBS) for vehicles of Categories M₁ and N₁ to introduce provisions for car-to-bicycle scenario as the second step of a two-step approach. (The IWG has prepared a separate proposal for the first step in this two-step approach. GRVA is therefore requested to make a decision on whether car-to-bicycle should be introduced in a single step or in a two-step approach.)

The purpose of this document is to help clarify the requirements of paragraph 7 and Annex 1 of the UN Regulation on uniform provisions concerning the approval of vehicles with regards to software update and software updates management system (ECE/TRANS/WP.29/2020/80) and provide information on what may be used to evidence those requirements.

Proposal to introduce provisions for approving single vehicles involved in modular vehicle combinations, e.g. towing trailers, “road trains”.

Proposal to improve the uniformity of requirements for stop lamp illumination with regard to various types of braking systems, including those of electric vehicles.

Proposal to amend the ALKS UN Regulation provisions to enable approval of systems operating at speeds up to 130 km/h.

Proposal to introduce additional requirements for a lane change functionality.

Proposal to introduce provisions for recently developed steering systems that have significantly lower steering gear ratios (i.e. quick steering characteristics).

Proposal by the experts from the Informal Working Group on Advanced Emergency Braking Systems (AEBS) for vehicles of Categories M₁ and N₁ to introduce provisions for the car-to-bicycle scenario as the first step of a two-step approach. (The IWG has prepared a separate document for the second step of this two-step approach. Alternatively, the IWG has prepared a proposal for a single (all-in-one) approach. GRVA is requested therefore to make a decision on whether car-to-bicycle should be introduced in a single step or in a two-step approach.)

Proposal to introduce requirements for endurance braking systems for vehicles equipped with an electric regenerative endurance braking system. This proposal is an alternative to the text proposed in document GRVA/2020/37.

Proposal to introduce requirements for endurance braking systems for vehicles equipped with an electric regenerative endurance braking system.

Proposal to permit automatic activation of functions providing continuous lateral and/or longitudinal control after ALKS deactivation.

Proposal to expand the scope to include N category vehicles and to apply the minimum performance for service braking systems (5 m/s²) as required in the 11 series of amendments to UN Regulation No. 13, for vehicles of the Categories M2, M3, N2 and N3. The overall objective of the former Informal Working Group (IWG) on Automatically Commanded Steering Function (ACSF) was to develop technical requirements for Automated Lane Keeping Systems (ALKS). The initial limitation to passenger cars (M1 category vehicles) was agreed in order to deliver within the given timeline. After having successfully accomplished the work for the system in a first step, the automotive industry has now reviewed and examined the existing requirements under the premise of including all vehicle categories M and N.

Proposal to permit lane changes during a Minimum Risk Manoeuvre (MRM).

The provision in paragraph 5.3.5. may need clarification on what the granting Approval Authority should do, if that Authority can’t take into account the comments received as per paragraph 5.3.4. Should it continue processing with granting the approval or postpone granting? The proposal is to clarify that the Approval Authority should postpone granting the approval until the agreement on the common interpretation of the questioned issue is reached.

Proposal to clarify requirements applicable to alternatives software identifications systems differing from the Regulation No. X Software Identification Number (RxSWIN) defined in the Regulation.

Proposal to allow a grace time in order to deal with unexpected changes in the radius of the curvature of a bend by permitting the system to exceed the ay_smax limit of 3 m/s² by a maximum of 40 per cent for up to two seconds.

Proposal to clarify that a continuation of support by a Category B1 ACSF after its boundary conditions have been exceeded may not be possible under conditions as outlined in the manufacturer’s safety concept.

Proposal to

1. Align lane-centering provisions with principles applied to UN R157 (ALKS)
2. Permit Category C ACSF to remain in stand-by during temporary roadway transitions
3. Clarify overriding provision (para. 5.6.4.3) reference to stand-by mode
4. Introduce a tolerance factor for “critical situation” lane changes
5. clarification to test conditions
6. Align direction indicator deactivation under a pass conditions with previously adopted provisions.

Proposal to allow up to seven seconds to start and perform a lane change.

Proposal to introduce provisions for truck/trailer data transmission for Category C ACSF.

Proposal to allow continuous movement of the driver as an alternative to the continuous actuation of the remote-control device as a means to assure driver attentiveness.

Proposal to introduce a Risk Mitigation Function designed to bring a vehicle to a safe stop in the event of fallback driver unavailability.

Proposal to remove Category R, S, and T vehicles unintentionally included in the scope of the regulation.

Proposal to replace the specification of the type and size of brake caliper and brake disc for brake lining CoP assessment with specifications for a pad area and thickness of the original approval. The original specification corresponds to obsolete caliper and rotor configurations no longer in widespread use.

Proposal to correct requirements for type-IIA (endurance braking performance) tests.

Proposal to permit the use of a software identification system that differs from the RxSWIN established under UN R156 on software updates. (This proposal corresponds with a proposal to amend UN R156).
