Working Party on Passive Safety | Session 67 | 20-23
Jul 2020
20. The expert from Germany reiterated his proposal (ECE/TRANS/WP.29/GRSP/2019/18) and referred to agenda item 3(a) (see paragraph 4). The expert from OICA introduced GRSP-67-07 as a counterproposal, aimed at clarifying the issue that vehicle height has an influence on the test results of headform and legform tests, and consequentially 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. Germany stated its agreement, in general, with the OICA proposal but suggested further clarifications. GRSP agreed to resume discussion at its December 2020 session on the basis of a potentially revised proposal from the experts of Germany, the United Kingdom and OICA.
Working Party on Passive Safety | Session 68 | 7-11
Dec 2020
20. The expert from Germany reiterated his proposal (ECE/TRANS/WP.29/GRSP/2019/18) and referred to agenda item 3(a) (see paragraph 4). The expert from OICA introduced GRSP-68-18 as a counterproposal of ECE/TRANS/WP.29/GRSP/2019/18, tabled by the expert from Germany. He explained that the proposal was reflecting the latest stage of discussions aimed at clarifying the issue that vehicle height has an influence on the test results of headform and legform tests. He also suggested to encompass this issue with ECE/TRANS/WP.29/GRSP/2020/9. GRSP recalled that this last proposal was prepared by the experts of the Drafting Task Force to align the UN Regulation with the revised General Safety Regulation of the European Union that would enlarge the head impact zone to include the windscreen area. The expert from Republic of Korea suggested that the impact test speed ratio should be aligned to that one identified by the IWG-DPPS (see para. 5 above). Finally, GRSP agreed to resume discussion to the proposals of amendments to the UN Regulation at its May 2021 session.
Working Party on Passive Safety | Session 70 | 6-10
Dec 2021
19. The expert from Germany introduced GRSP-70-17 (superseding ECE/TRANS/WP.29/GRSP/2019/18), concerning new provisions to cope with Adjustable Ride Height Suspension System (ARHSS). GRSP agreed to distribute GRSP-70-17 with an official symbol at its May 2022 session, as draft 04 series of amendments to UN Regulation No. 127.
