Proposal for amendments to document ACSF-07-02.

Draft procedure for lane-guidance assistance systems (category B1 ACSF).

Proposal for new paragraphs in the draft ACSF amendment concerning provisions to ensure the system capacity to monitor and adapt to road conditions and the environment surrounding the vehicle in order to ensure safe behavior and minimize risks. This proposal replaces paragraphs in the previous document ACSF-06-28 based on the discussions of the 6th meeting and document ACSF-06-18 by OICA and CLEPA.

Proposal of a research project to assist the ACSF informal group in the development of provisions for the approval of lane-keeping and lane-change assistance and other ACSF systems.

Proposal of provisions regarding the use of a type approval numbering system that includes information on the ACSF capabilities and software version.

The draft amendment to enable automated steering systems for use at speeds above 10 km/h includes provisions for a minimal risk maneuver (MRM) in the event that the driver fails to respond to a demand to assume control of the vehicle. This document proposes provisions for the automatic activation of hazard warning lights under an MRM scenario.

Breakdown of the requirements of the draft consolidated amendment (ACSF-06-28) for each category of ACSF.

Table of ACSF categories as defined by functions and requirements of the draft amendment to UN R79.

Consideration of the borderline in distinguishing between corrective steering functions and automatically commanded steering functions towards defining requirements for the approval of automated steering systems.

Proposal towards defining corrective steering functions as a distinct function apart from automatically commanded steering functions.

OICA input on definition of corrective steering and automatically commanded steering functions.

The proposal is aimed at ensuring that the English and Russian texts are equivalent. In the English text, which is the original, in paragraph 2.2.27 of Annex 12 the word “travel” is used. The corresponding word in Russian language should be “ход”. The original text was mistranslated into Russian.

Proposal to clarify paragraph 8.1.2. The paragraph aimed to verify that the compensator can accept a difference of the travel when one brake operates in forward direction and the other in rearward direction with a margin of twenty per cent.

UN R13 allows for the exemption of certain vehicles from the requirement for electronic stability controls. This proposal seeks to clarify the scope of the exemptions to include any special purpose vehicle with a non-standard chassis. The change was prompted by a modified vehicle where use of ESC was not feasible, but where the current UN R13 language left doubt as to whether the ESC requirement was applicable. This revised proposal takes into account comments received during the February 2016 GRRF session.

Proposal to introduce technical requirements for Corrective Steering Functions (lane departure prevention, lane-keeping assistance (LKAS), steering angle correction, etc.) as defined in the regulation. The proposal offers four options to ensure appropriate approvals of LKAS and related CSF systems until such time as more precise requirements can be defined:

• Option 1 and option 2: Not to grant any type approvals for corrective steering functions until detailed technical requirements for CSF are incorporated into this Regulation.
• Option 3: Amend the definition of CSF as proposed in this document.
• Option 4: Amend the definition of corrective steering functions and to include technical requirements for LKAS as an ASCF of Category B1 as proposed in this document.
