• 2 Step Initiation (by two deliberate actions)
• Monitoring to the rear and to the side
• Restriction to a designated infrastructure
• Hands On during lane change manouevre

Proposal to delete obsolete paragraphs and amend the target completion date for the informal group’s work from September 2017 to September 2018.

Proposal of 2.5 seconds for return to original lane after aborted lane change with 48.6-meter rearward sensing range (34.7-meter minimum distance for 2.5 seconds plus one second safety margin).

Discussion of requirements for minimum distance from approaching vehicles for a safe automated lane-change maneuver.

Japanese proposal for false positive testing of automated emergency steering systems.

Diagrams to illustrate Japan’s proposal (ACSF-13-13) for false-positive testing of emergency steering functions.

Proposals concerning the draft amendment to introduce emergency steering and automated lane-change functions into UN R79. Document GRRF-84-36 has been formalized as document GRRF/2017/27 for consideration during the special 85th GRRF scheduled to finalize a proposal for automated lane-change systems.

Revised version of the draft terms of reference (document GRRF-83-18) 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.

Japanese guidelines on automated emergency braking systems (AEBS) pursuant to Kokujigi No. 353 of February 21, 2003 as amended by Kokujigi No. 181 of November 15, 2005, Kokujigi No. 143 of October 25, 2007, Kokujigi No. 139 of October 7, 2008, and Kokujigi No. 127 of June 30, 2011.

Comments on the working draft developed during the first DPPS task force session (DPPS-01-05/Rev.1).

Japan proposes that the EPPR informal group launch work on the OBD2 GTR by January 2018. Japan intends to introduce new domestic regulatory requirements in October 2020 which will require public notification around October 2018. Therefore, Japan would like the EPPR informal group to have agreed the principle requirements of the harmonized GTR before October 2018.

Japan input responding to document EPPR-21-06.

Discussion to kick off phase 2 work on defining uniform methods for assessing the risk of thermal propagation across the REESS.

Discussion of issues related to the transposition of the EVS GTR-Phase 1 provisions, especially the scope/application and marking requirements, into UN R100.

Japan responses to the EVS informal group request for input concerning thermal propagation testing across electric vehicle battery cells. (EVS informal group action item 9 from the 14th session)

Summary table current research projects in Japan regarding electric vehicle REESS thermal propagation testing. (EVS informal group session 14 action item 11)

Presentation of Japan research into thermal propagation. (Action item 1 from the 14th EVS informal group session)

Proposal for a new working group to develop harmonized technical specifications, test procedures and performance requirements for audible warning systems that signal when a category M₃, N₂, or N₃ vehicle is moving in reverse gear.

Proposal to:

1. delete paragraphs 6.2.7.6.2. to 6.2.7.6.3.2. concerning transitional provisions for the 05 series of amendments,
2. to clarify that drivers may not switch OFF the dipped-beam headlamps manually when they are switched ON automatically according to paragraph 6.2.7.6.1., and
3. to clarify that daytime running lamps shall not be switched OFF except as specified in paragraphs 6.19.7.1. to 6.19.7.6. (For example, DRLs shall not be switched OFF when only the position lamps are ON.).

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.

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.

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.
