This document presents changes agreed by an informal group of experts reviewing the content of Annex 6 since the 84th session of GRRF. The proposal aims to clarify the purpose of Annex 6 and ensure its suitability when used in the assessment of steering systems featuring advances in automation (i.e., ACSF).

Updated text of provisions from the informal group on ACSF for the approval of emergency steering functions and driver-initiated automated lane changing systems.

Proposal of provisions for the approval of emergency steering functions under Regulation No. 79.

Proposal to cease approvals under the 02 series of amendments from September 2020 in order to allow manufacturers adequate time to adapt to the new requirements;

• ESF, ACSF C and unexpectedly ACSF B1 (despite originally assumed to be compatible with ACSF C new requirements),
• new CEL assessment (documentation, tests…) whose scope is also extended to all non-complex electronic systems under series 03.

Regarding the application to “All Types” (e.g. for new registration), industry proposes to leave unchanged the existing vehicles on the market which are approved on the base of national of regional exemptions by Contracting Parties signatories of the UN R79 regulation, given the heavy technical impacts on ACSF C (sensor range…) which are indirectly affecting ACSF B1 systems that were initially assumed to be compatible with cat. C (e.g. 3s hands-off detection instead of 15s, lane centering prior to the lateral movement towards the marking etc.), and the add-on of requirements restricting design possibilities without clear safety benefits (e.g. the use of direction indicators to suppress the procedure).

Japan comments on the changes agreed by the informal group of experts which reviewed the content of Annex 6 and proposed (via document GRRF-85-1/Rev.1) to clarify the purpose of Annex 6 and ensure its suitability when used in the assessment of steering systems featuring advances in automation (i.e., ACSF). The proposal

1. corrects an editorial error by inserting a missing clause in paragraph 1, and
2. deletes the phrase “at least 10%” from paragraph 4.1.1. which changes the current meaning of text with regard to assessment of “the System”
   • Japanese technical services already verify each declared function by the manufacturer under the paragraph,
   • The wording “at least 10%” may result in a decrease in the number of tests where Japan believes number of tests should be decided by the Technical service considering which tests should apply.
