Proposal from the Informal Working Group on Advanced Emergency Braking Systems (AEBS) for vehicles of Categories M1 and N1 in order to supplement the proposals of document GRVA/2020/35 to improve the text on a number of issues.

This proposal revises the changes proposed in document GRVA/2020/7 based on stakeholder feedback. The proposal introduces provisions for M₁ vehicle to allow for lateral accelerations up to 40% greater than the 3 m/s² limitation for a period up to two seconds in order to in order navigate unexpected changes in the radius of the curvature of a bend and avoid driving behaviour that may be unexpected and/or confusing to the operator and following vehicles.

Proposal for amendments to document GRVA/2020/22.

Proposal for an alternative to ensure user attentiveness when activating a remote-controlled parking system.

Proposal to modify the following elements:

1. paragraph 5.6.4.2.3., delete “temporarily”
2. paragraph 5.6.4.5.2.1., replace “actually” by “anticipated to be”
3. paragraph 5.6.4.6.6., B1 shall resume “in a timely manner”
4. paragraph 5.6.4.6.8.1., clarify the suppression criteria
5. paragraph 5.6.4.7., define distance tolerances for lane-change critical distances
6. Annex 8, Paragraph 2., Carry over the language already adopted for ACSF B1: “At the manufacturer’s discretion and with the agreement of the Technical Service, a lane with a width of less than 3.5 m may be used, if the correct function of the system on roads with wider lanes can be demonstrated.” and allow for lower temperature and wet surface test conditions, and
7. Annex 8, Paragraph 3.5.1.2. (j), amend the pass condition with regard to direction indicator deactivation.

Consolidated proposal incorporating comments from OICA/CLEPA, CITA, Germany, and AVERE (including most recent proposal to the 7th GRVA session).

This document proposes a new 04 series of amendments to Regulation 79 with regard to a system that aims at bringing the vehicle to a safe stop in case of driver unavailability, defining a “risk mitigation function”.

Proposal to permit manoeuvring assistance in defined low speed driving situations to reduce damages and injuries.

The intention of the proposed amendment is to clarify the existing text on continued support of an ACSF B1 if the boundary conditions are exceeded. It clarifies that under certain circumstances, e.g. if there are no lane markings present or if the vehicle has already drifted substantially out of the lane such that the lane may no longer be recognized, a continuation of support may no longer be possible or reasonable.

Proposal to amend the proposal from Germany regarding lane-change functionality:

1. paragraph 5.2.1. – lane keeping
2. paragraph 5.2.6.1. – risk to safety of the vehicle occupants and other road users
3. paragraphs 5.2.6.2. and 5.2.6.3. – preconditions for a lane change procedure
4. paragraph 5.2.6.5. – timing of a lane change maneuver
5. paragraph 5.2.6.6. and its sub-paragraphs – criticality of a lane change maneuver
6. paragraph 7.1.3. – rear detection range
7. Annex 5. – test cases for rear detection range, lane change.

The proposal aims to correct 5 types of inconsistencies:

1. The reference to Annex 4 is repeated in each sub-paragraph and should instead be stated once in each paragraph.
2. Acronyms are used inconsistently. Proposal to use them consistently throughout similar to UN-R79, e.g. Emergency Manoeuvre (EM), and when used in the text as “emergency manoeuvre”
3. Each sub-paragraph has a heading, this helps understand the structure and should be carried over to par. 8.1., 9.1. and 9.2. as well, the wording for the heading of par. 9.1. and 9.2. are derived from UN-R155 and UN-R156 respectively.
4. Consistent use of term throughout, e.g. R₁₅₇SWIN without blank, Cyber Security as two words as used in UN-R155
5. Editorial corrections, e.g. missing paragraph numbers, missing full stop in the paragraph number.

The intention of the proposed amendment is to clarify the existing text on continued support of an ACSF B1 if the boundary conditions are exceeded.

Proposal to include all vehicle categories M and N in the scope of UN R157.

Under the initial ALKS regulation and its reference to the new cyber security requlation, manufacturers are permitted to use an alternative software identification system instead of the proposed RxSWIN format. This proposal seeks to clarify the use of such alternative identifications in the approval process.
