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.

Revised set of amendments to improve and clarify the draft amendment to UN R79 for introduction of provisions for corrective steering and ACSF category A and B1 systems. In particular, the revised document seeks consensus on symbols and interaction between the system and driver, including specifications for notifications related to the status the driver’s hands on the wheel.

Proposal for amendments to the draft amendment to introduce provisions for corrective steering and category A and B1 automatically commanded steering functions (ACSF) into UN Regulation No. 79 as agreed during the 83rd GRRF session.

Proposal for amendments to the draft amendment to introduce provisions for corrective steering and category A and B1 automatically commanded steering functions (ACSF) into UN Regulation No. 79 as agreed during the 83rd GRRF session, including the proposal to allow for the approval of systems that do not comply with the mandatory use of the color red for the “hands off” steering wheel warning symbol (introduced by this amendment) until 1 April 2020 for consideration by the World Forum.

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.

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.

Revised proposal pursuant to GRRF discussions 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 appropriate.

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).

Proposal for a harmonized symbol with option for explanatory text to signify a request for and status of the driver’s hands on the steering wheel when the vehicle is in an ACSF mode.

Proposal to clarify the intent of “a means of detecting that the driver is holding the steering control” by specifying that the vehicle manufacturer would define “holding the steering control” (e.g., one hand, two hands, firmness of grip, etc.) for each vehicle/system under test.

Proposal to amend the annex on complex electronic systems, in particular, to require auditing of the methodologies used to ensure system safety at both concept and system level. Concept level specifically requires consideration of interaction with other vehicle systems.

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.
