OICA-CLEPA proposals for amendments to the draft corrective steering/ACSF B1 amendments to UN R79 (revisions to GRRF-82-12/Rev.3 approved at GRRF-82 and subsequently submitted for the March 2017 WP.29 session as WP.29/2017/10).

Proposal to introduce corrective steering and B1 level ACSF type approval provisions into UN R79. This proposal would enable the approval of corrective steering and lane-keeping assist systems in addition to current provisions for automated steering functions that operate at speeds up to 10 km/h.

Proposal for category C automated steering requirements.

Proposal to develop an amendment in order to align GTR No. 3 with technical progress, addressing among others: ensuring electromagnetic immunity of ABS-systems, introducing ABS performance requirements for category 3-5 vehicles (three-wheelers), ensuring uniform requirements for equipment such as Electronic Stop Signal System and the means to disable the ABS, if equipped. This amendment aims to harmonize GTR with recent amendments made to UN Regulation No. 78.

Proposal to correct mistranslation of the original English into the Russian version of the text. In the English text, paragraph 2.2.27 of Annex 12 uses the word “travel”. The corresponding word in Russian language should be “ход”. The proposal is aimed at ensuring that the English and Russian texts are equivalent.

Proposal to simplify the verification of sufficient movement on the balancer (of the compensator) without having to take measurements underneath the trailer in an potentially unsecured position and to correct the text of Annex 12 (Conditions governing the testing of vehicles equipped with inertia (overrun) braking systems). Intention to provide an objective calculation method as part of setting requirements for permissible “differential travel” or swivel.

ACSF informal group revisions to the proposal to introduce corrective steering and B1 level (lane-keeping) automatically commanded steering functions provisions into UN R79. The proposal substantially revises the corrective steering test procedure, providing greater clarity over the procedure and requirements, and makes editorial corrections.

Proposal to align GTR No. 3 with technical progress, addressing among others: electromagnetic compatibility/immunity of ABS-systems, ABS performance requirements for category 3-5 vehicles (three-wheelers), uniform requirements for equipment such Emergency Stop Signal and the means to disable the ABS, if equipped. This amendment aims to harmonize GTR with recent amendments made to UN Regulation No. 78.

Proposal to delete passages under paragraph 3.1.15.2. referring to the “prediction of the vehicle deceleration” since no method for doing so is described in the regulation. Moreover, in a self-certification system, the requirement would have to be met for the actual vehicle deceleration. The proposal also substitutes switching between ABS modes for the terms “disable” and “deactivate” for greater clarity. Lastly, the proposal recommends the use of a clearly specified telltale design to signal the ABS operating status rather than to leave this function open to “…any other equivalent unequivocal indication of the disabled antilock brake system state.”

Proposal to extend the scope of UN R131 to include light vehicles in line with priorities in Japan, the EU, and USA with regard to the installation of AEB systems on passenger cars and light trucks.

Proposal to authorize the establishment of an expert group to draft test procedures and performance requirements for M1/N1 with regard to automatic emergency braking, including stationary and moving obstacles, and for pedestrian AEBS.

OICA request for confirmation that:

• the provisions for CSF, ACSF A and ACSF B1 will be introduced via a new supplement 06 to the current series of amendments to UN R79;
• the vehicles approved prior to the introduction of the new supplement will not be required to comply with it, even in case of an extension.

Proposal to amend provisions on electronic stability control warnings under braking regulations to allow for activation of the ESC visual warning during a stability-assistance intervention of an electronic steering control. The aim is to avoid separate requirements for brake-actuated and steering-actuated stability assistance that would lead to two visual warnings where only one is appropriate.

Comments concerning the clarity and utility of certain provisions in the proposal to amend the annex on complex electronic systems.

OICA comments and questions regarding the EC proposal to amend the UN R79 annex on complex electronic systems to require auditing of methodologies used to ensure system safety at both concept and system level.

Document GRRF-83-08 proposes modifications to document WP.29/2017/10 proposing amendments to UN R79 to enable the approval of corrective steering and category A and B1 automated steering systems (ACSF).

Update on the ad hoc group discussing how to clarify UN R90 with regard to replacement brake components, including discussions on the merits of extending the scope to brake calipers which also relates to discussions on remanufactured components.
