Draft proposal to enable the approval of automated emergency steering systems intended to avoid or mitigate collisions. The proposal based on document ACSF-14-07 submitted by OICA and CLEPA which was discussed during the 14th meeting of the ACSF informal group. The square brackets indicates paragraphs which are still under discussion in the informal group.

Comments submitted to GRRF through the secretariat proposing amendments to the draft text on automated lane-change systems.

Presentation on remanufactured brake calipers as part of the discussion on whether such products should be subject to a new UN Regulation separate from UN R90. CLEPA does not believe these products require a new regulation.

Correction of a reference used in the original proposal for a new UN Regulation on agricultural vehicle couplings. In Annex 6, paragraph 1.7., 3.3.6. and 3.7.1.: The Term F_s is not needed and misleading. The vertical component of the test force is named F_v. This term should be used throughout the whole document concerning the vertical component of the test forces.

Proposal to allow adaptation of speed and distance calculations in accordance with national speed limits since some nations enforce maximum speed limits below the 130 km/h used as the basis for the proposals on automated lane-change systems. Japan expects to refine the proposal in order to address mutual recognition concerns inherent in such recourse to national requirements. Japan further proposes clarification of the approaching vehicle (motorcycle) test target pending development of uniform test target specifications.

Diagram illustrating the phases of a lane-change maneuver as envisioned by the Category C¹ ACSF amendment to UN R79.

Set of diagrams illustrating the phases and timing of the test procedure for an automated lane-change maneuver as envisioned by the draft amendment to introduce Category C¹ ACSF into UN R79. These figures include the vehicle under test and approaching motorcycle speeds and distances under the lane-change phases, including timing and duration of each phase.

Vehicle manufacturer perspectives on the permissibility of non-driving activities by the operator of a highly automated vehicle. This presentation relates to discussions between traffic regulators (represented by UN Working Party 1) and vehicle regulators (represented by UN Working Party 29) on responses under traffic laws and vehicle regulations to the advent of automated driving systems.

OICA presentation on a field study undertaken to collect data on tyre pressures of vehicles in use towards assessing the effectiveness of direct and indirect tyre-pressure monitoring systems on the maintenance of correct inflation levels.

Proposal to correct the paragraph numbering of the original proposal for amendments to Regulation No. 54 contained in document GRRF/2017/18. The introduction of new paragraphs by Supplement 21 and the separation of paragraph 3.1. into subparagraphs 3.1.1. and 3.1.2. result in the proposed paragraph 3.1.12. being renumbered as 3.1.13.

Proposal as approved by GRRF during its 84th session to correct references to paragraphs in Regulations Nos. 30 and 54 which need updating pursuant to renumbering in the source regulations.

Draft amendment to UN R79, including provisions for emergency steering functions (ESF), Category C[1] ACSF for lane-change maneuvers, and updating of Complex Electronic Systems (CEL) Annex 6 provisions. This document was prepared during the 84th GRRF session for consideration during the special 85th GRRF scheduled to finalize a proposal for automated lane-change systems.

Speadsheet tool designed to calculate time and distance requirements based upon speeds of vehicle under test and test target motorcycle under the proposed procedures for evaluating Category C[1] ACSF automated lane-change systems.

Presentation by the WP.1 chairperson of traffic regulator perspectives on automated driving, cybersecurity, and related subjects.

Revised proposal, as approved during the 84th GRRF session, to enable activation of the ESC optical symbol in cases of a corrective steering function intervention when the CSF intervention is activated under the control of an ESC system. The aim is to avoid separate requirements for brake-actuated and steering-actuated vehicle stability functions (VSF) that would lead to two optical warnings where only one is necessary. This would enable use of the ESC intervention tell-tale for CSF steering intervention.

Proposal to introduce provisions for driver-initiated automated lane-change systems (Category C ASCF) and for automated emergency steering functions (ESF).

Proposal to clarify the purpose of UN R139 which was originally established through the extraction of brake assist system (BAS) provisions from UN R13-H on brake systems. Within the context of UN R13-H, the BAS provisions were written to assess performance in cases where a vehicle was fitted with a brake assist system. As a stand-alone regulation, UN R139 applies only to vehicles that are equipped with BAS. Therefore, this supplement proposes to refine the text to remove the “if fitted” language and ensure that UN R139 can only be applied to a vehicle equipped with a BAS.

Proposal to remove “if fitted” language from the text to clarify that UN R140 can only be applied to a vehicle equipped with a ESC system. UN R140 was originally established through the extraction of electronic stability controls (ESC) provisions from UN R13-H on brake systems. Within the context of UN R13-H, the ESC provisions were written to assess performance in cases where a vehicle was fitted with an electronic stability control system. As a stand-alone regulation, however, UN R140 applies only to vehicles that are equipped with ESC. The proposal also would correct an apparent error in to Annex 4, paragraph 2.1. where the reference to “ISO 15037 Part 1:2005” should read “ISO 15037 Part 1:2006”.
