Proposal for amendments to the bumper test area and headform test procedure.

Consolidated version of UN R127 on pedestrian safety incorporating its Corrigendum 1, Supplement 1, and draft 01 series of amendments that would align the test requirements of UN R127 with GTR No. 9’s Phase 2 (Flex-PLI) and Amendment 2 to (determination of the headform test points).

With informal document GRSP-54-07, the European Commission presented modifications to GTR No. 9 considering the discussion on the headform test procedures in the GTR and also including amendments proposed by other parties. The details as well as the proposed wording were discussed in the GRSP sessions between the 48th session in December 2010 and the 53rd session in May 2013.

This document presents the subsequent changes to UN Regulation 127.

Proposal to amend the draft 01 series of amendments (document WP.29/2014/38 pending for the June 2014 WP.29 session) to bring its “commencement date” and validity-of-approvals provisions into line with the recommendations for the International Whole Vehicle Type Approval system (i.e., to set the effective date to 1 September 2018 and confirm the validity of earlier approvals after the introduction of the 01 series of amendments).

Presentation of an assessment of 2D vs. 3D impactor positioning methods.

Proposal to amend the draft 01 series of amendments (document WP.29/2014/38 pending for the June 2014 WP.29 session) to bring its “commencement date” and validity-of-approvals provisions into line with the recommendations for the International Whole Vehicle Type Approval system (i.e., to set the effective date to 1 September 2018 and confirm the validity of earlier approvals after the introduction of the 01 series of amendments).

Proposal to remove the specification of “±0.01 m/sec” for the accuracy of the velocity measurement in Annex 5, Paragraph 3.2.1. This would leave in place the specification to use the measurement procedure if ISO 3784:1976 which specifies an accuracy of ±1 %.

OICA comments and concerns regarding the generally accepted proposal for the definition of the bumper test area for use with the Flex-PLI lower leg impactor. The document raises issues concerning limitations of the test procedure and notes that the new requirements would have a significant impact on bumper design such that the transitional period for implementation should be 2019 to allow for a full vehicle development cycle.

Formal proposal as generally agreed during the 56th GRSP session to revise the procedure for determining the bumper test area under the pedestrian safety regulation. This proposal corrects shortcomings in the current definitions which could lead to a narrower test area than intended (leading to less effective pedestrian protection). This proposal includes a “bumper beam” determination method. The proposed changes also require the form of a new series of amendments (rather than a Supplement) and proposes a transition date of 1 September 2019 (rather than the previous 2017).

The proposal also includes a September 2017 transition date in the event that the GRSP determines that the proposal should be treated as a new series of amendments rather than as a Supplement.

Proposal of provisions that can be applied within GTR No. 9 based upon the text developed for Revision 3 of the 1958 Agreement (Schedule 8) on the validation of a simulation method.

Proposal as revised during the first DPPS task force session.

Presentation on the Pedestrian Detection Impactor 2 performance. The PDI-2 was developed jointly by the Altran Concept Tech GmbH and ACEA to test sensor systems for active pedestrian protection systems (e.g. active engine bonnets).

OICA Proposal for a Rev. 4 of Document TF-DPPS/2/03 (Requirements Overview Deployable Pedestrian Protection Systems).

Input regarding the testing of systems with and without deployment of the pedestrian protection system.

HIT and WAD discussion for assessment of deployable pedestrian protection systems.

Input for the draft provisions on deployable pedestrian protection systems under GTR 9 and UN R127.

Counter-proposal to document GRSP/2019/18 to address pedestrian safety and active suspensions (a system which could change the vehicle height while driving (up to a defined driving speed, e.g. up to 39 km/h)). Since the vehicle height has an influence on the headform test area (WAD) and on the test results for legform tests, all possible vehicle heights up to a driving speed of 11.1 m/s (40 km/h) should be considered to be relevant for impact with a pedestrian.

Proposal to amend the definitions and specifications as well as the Annex 1, Part 1. It is a revised counterproposal to document ECE/TRANS/WP.29/GRSP/2019/18 submitted by Germany and the OICA informal document GRSP-67-07.

Counter-proposal from OICA to a German proposal (GRSP/2019/18) to address vehicles with active suspensions and amend the definitions and specifications and Annex 1, Part 1. This document supersedes previous OICA submissions GRSP-67-07 and GRSP-68-18.

Proposal by the experts from OICA to add some further suggestions to GRSP-70-12

Revised proposal prepared by the secretariat pursuant to discussion of GRSP/2021/28, proposing to align UN R127 with provisions set out in the revised General Safety Regulation (EU) 2019/2144 that will apply in the European Union in accordance with the proposed transitional provisions. The proposal also covers a specific provision on optional monitoring of headform contact with A-pillars, windscreen header and cowl and proposes inconsequential adaptations and clarifications to the existing requirements.

The proposed test makes a few minor adaptations and clarifications to the existing requirements.

Proposal to amend document GRSP/2022/4 concerning provisions for Adjustable Ride Height Suspension Systems (ARHSS). This proposal supersedes the previous proposals in documents GRSP-67-07, GRSP-68-18 and GRSP-70-17.

Proposal for clarifications to the text (subsequent to documents WP.29/2022/70, WP.29/2022/129 and WP.29/2022/130), especially relating to the definitions of the cowl monitoring, the windscreen, and the jerk areas.
