Proposal to introduce new requirements for Complex Electronic Control Systems, in line with the corresponding provisions for passenger cars in UN Regulation No. 13-H

Draft proposal to introduce a definition, requirements, and a test procedure for CRS lower tether anchorages.

43. The expert from the Netherlands introduced GRSG-124-27, narrating a lack of consistency between different UN Regulations and UN GTRs when referencing different versions of the three-dimensional H point machine and the test procedures to measure the H point. He further provided a proposal (GRSG-124-30) indicating possible solutions to solve such inconsistencies. GRSG agreed on GRSG-124-30 as a possible solution and to: (a) introduce it informally at the AC.2 November 2022 session, (b) explain the GRSG solution in the highlights of the Chair of GRSG at the November 2022 session of WP.29, and (c) seek agreement on the use of the concerned SAE standard (drawings and specifications of the machine) with an SAE representative to WP.29, with the support of the representative of the Netherlands.

Input concerning the review of existing UN Regulations and Global Technical Regulations with regard to their application to vehicles equipped with Automated Driving Systems.

This informal document proposes amendments to UN R78 to introduce new requirements for “Complex Electronic Control Systems” aimed at addressing new technologies such as automatically commanded braking.

Proposes the addition of design qualification tests also will harmonize with ISO 15500-13:2012, and the North American CSA/ANSI PRD 1 (2020).

20. GRSG considered documents prepared by the Task Force on UN Regulation No 110: (a) ECE/TRANS/WP.29/GRSG/2022/23 that introduces the minimum opening set pressure of the primary Liquid Natural Gas (LNG) relief valve, (b) ECE/TRANS/WP.29/GRSG/2022/24 and (c) ECE/TRANS/WP.29/GRSG/2022/25 that updates the existing requirements for CNG/LNG fuelled components. The expert from OICA proposed that the three documents be combined together as a new series of amendments. Therefore, he introduced GRSG-124-31-Rev.1, consolidating the three proposals and amending ECE/TRANS/WP.29/GRSG/2022/24. GRSG adopted ECE/TRANS/WP.29/GRSG/2022/23, ECE/TRANS/WP.29/GRSG/2022/24 and ECE/TRANS/WP.29/GRSG/2022/25 as amended by annex II to the session report. The secretariat was requested to submit the combined document of the three proposals as the 06 series of amendments to UN Regulation No. 110 for consideration and vote at the March 2023 sessions of AC.1 and WP.29.

Update paragraphs to be in line with the requirements of ISO15500 and NGV3.1 (industry standards for CNG):

67. The representative from The Netherlands introduced GRPE-86-39 on the developments in the Netherlands with regard to checking vehicle emissions in PTI. The representative from EUROMOT sought further clarifications about the intention with non-road mobile machinery data. The representative from The Netherlands informed that the intention was to provide emission requirements for any construction/ renovation projects for public procurements, including NOx emissions quotas for the projects to be met by the service provider, where an amount of NOx emissions would be contractually agreed.

18. The expert from the Netherlands introduced GRSP-71-17 to GRSP which decided to collect more information on the barriers that have been used for type approval testing of lateral impact and on their compliance or not with UN Regulation No. 95. For the time being, GRSP agreed to resume discussion at the December 2022 session until more information would be made available to make sure that barriers used for type approval testing are fully compliant.

46. The expert from the Netherlands gave a presentation (GRSP-71-18) to introduce a future proposal of amendments to UN Regulation No. 134, considering the background of UN Regulations Nos. 12, 94 and 95 to have a consistent approach in all crash test configurations. He added that all UN Regulations on vehicle impact concern vehicle categories M1 and N1 against a passenger car (M1) and are not intended to cover the impact of a truck or bus against another vehicle. Impact tests were not required for N2, N3, M2 and M3 category of vehicles. The expert from OICA further proposed to establish a task force to align UN Regulation No. 134 with UN GTR No. 13, Phase 2. GRSP agreed to establish the task force with the Netherlands as coordinator and OICA (Ms. A. Schuessling, contact) as secretariat, which would start transposing UN GTR No. 13, Phase 2 into UN Regulation No. 134. Participants would include the experts from France, Japan, EC, CLEPA and other stakeholders for the time being. The task force would be expected to encompass GRSP-71-12 into the solutions provided for the issues highlighted in GRSP-71-18 and submit at least an informal document to the December 2022 session of GRSP.

27. GRSP considered GRSP-71-19 under agenda item 14 (see para. 31 below).

31. The expert from the Netherland introduced a presentation (GRSP-71-19), highlighting the lack of definition of “lower strap anchorages” or “lower tether anchorages”, as well as of specific strength requirements for the straps, the tethers and possible retractors used. GRSP agreed to discussion at its December 2022 session on a proposal of amendments on lower strap anchorages by an ad hoc group led by the expert from the Netherlands.

42. The expert from the Netherlands introduced a presentation (GRSP-71-08) on the background history of the work on harmonizing the three-dimensional H-point machine (3D H-point machine) that had ended. He urged that the work resume as soon as possible since the setting of the H-point stature was unclear and not consistent. He explained that Technical Services and laboratories accredited to ISO 17025, had met problems accrediting their test procedures, since the 3D H-point machines available on the market do not meet or cannot be calibrated according to the old specifications. GRSP agreed to restart the discussion on the lack of harmonization of the 3D H-point machine so as to reach a common understanding and solutions with the support of GRSP.

26. The expert from the Netherlands, on behalf of the Technical Services Group (TSG) introduced ECE/TRANS/WP.29/GRSP/2022/8 aiming at clarifying the requirements for monitoring the chest deflection of the Q10 dummy as well as the correct measurement of the location of the thoracic spine. He also introduced ECE/TRANS/WP.29/GRSP/2022/9, complemented by GRSP-71-02, on behalf of the Ad-Hoc group on annex 25 (Spain, Germany, Netherlands, TSG, CLEPA) to amend the existing procedure of measuring the prescriptions of the minimum sitting height for booster cushions. GRSP adopted ECE/TRANS/WP.29/GRSP/2022/8 and ECE/TRANS/WP.29/GRSP/2022/9 not amended (to be combined with ECE/TRANS/WP.29/GRSP/2022/7). In the meantime, GRSP-71-02 was adopted for the sole purpose of helping the calculation of the minimum stature height (without any mandatory legal basis) as prescribed by ECE/TRANS/WP.29/GRSP/2022/9, and therefore GRSP-71-02 would not be submitted to WP.29 and AC.1 for adoption. The secretariat was requested to submit the proposals as part of (see para. 25 above) draft Supplement 8 to the 03 series of amendments to UN Regulation No. 129 (Enhanced child Restraint Systems) for consideration and vote at the November 2022 sessions of WP.29 and to the AC.1. Moreover, it was agreed that a new webpage under “reference material” on the website of WP.29 would be on the above-mentioned calculator (GRSP-71-02).

Text corrects errors/mistakes in the current regulation and update text to be in line with the requirements coming from ISO15500 and NGV3.1 (industry standards for CNG)

38. GRSG considered the proposal for Supplement 1 to the 05 series of amendments to UN Regulation No. 110 natural gas/liquified natural gas (CNG/LNG) vehicles in GRSG-123-28 (superseding ECE/TRANS/WP.29/GRSG/2022/13), to update the existing requirements for compressed CNG/LNG fuelled components. GRSG agreed to resume discussion at its October 2022 session on a new official proposal drafted by a Task Force coordinated by the expert of NGVA Europe.
