45. The expert from International Association of the Body and Trailer Building Industry (CLCCR) introduced GRSP-69-30, to propose a future amendment to UN Regulation No. 100 to introduce provisions for a kind of an electric axle in a trailer. As a first step he asked the opinion of interested expert on this subject, to check defined requirements and review possible use cases for the trailer. GRSP agreed to resume discussion on this subject at its December 2021 session.

Text as revised during the 10th BMFE informal group session.

115. The expert from CLCCR held a presentation on Advanced axles in trailers, addressing new technologies to reduce CO2 emissions for vehicle combinations, with the aim of launching discussions within GRSG on the subject matter. The presentation contained information on the state of the art of the development of independently driven trailer axels using a dedicated electric power source, highlighting that electric trailer propulsion offers a wide range of applications (recuperation, acceleration, support start/stop manoeuvres) which could contribute to lowering CO2 emissions of vehicles. He explained that the introduction of such technology in the market would require the amendment of the definition of trailers in R.E.3 and in the Special Resolution No. 1 concerning the common definitions of vehicle categories, masses, and dimensions (S.R.1), as well as its alignment in several relevant UN Regulations (Nos. 13 and 100). He asked GRSG experts for feedback concerning the potential amendment of the relevant definitions, inquired concerning interest in possible discussions on the subject matter among interested stakeholders, and proposed that CLCCR put forth a proposal in this respect at the October 2021 session of GRSG.

116. Following comments and feedback from France, Germany, the Netherlands and the European Commission, addressing potential safety implications that the new technology poises in terms of the interaction of the trailed and the towing vehicle, GRSG invited interested stakeholders to work with CLCCR on this topic towards potentially tabling a proposal that would allow the emerging technology to be aligned with UN Regulations at the upcoming sessions of GRSG.

27. GRE took note of GRE-83-29 and GRE-83-42 and requested their submission as official documents to the next session. GRE also took note that an updated proposal for the sun load impact would be submitted to the next session (GRE-83-40).

Proposal to expand the scope of the regulation by deleting paragraph 1.2.2. which allows for the exclusion of “vehicles designed and constructed for special purposes where it is not possible, for practical reasons, to fit lateral protection devices” from the text. The proposal allows Type Approval Authorities to nonetheless exempt “vehicles where any LPD (e.g. fixed, removable, foldable, adjustable, etc.) is incompatible with their on-road use” through the addition of new paragraphs.

27. The expert from CLCCR introduced ECE/TRANS/WP.29/GRSG/2016/18 amending the scope of the Regulation to ensure that as many vehicles as possible were fitted with a lateral protection device and preferred to insert derogations for some niche products (GRSG-110-20-Rev.1). The expert from the United Kingdom raised concerns and preferred to keep the amendments as proposed in ECE/TRANS/WP.29/GRSG/2016/2 which allows Contracting Parties to object or accept such lateral protection devices. GRSG noted a number of comments on and general support for ECE/TRANS/WP.29/GRSG/2016/18.

28. Finally, GRSG adopted ECE/TRANS/WP.29/GRSG/2016/18 and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their March 2017 sessions, as draft Supplement 1 to the 01 series of amendments to UN Regulation No. 73.

Proposal to amend document GRSG/2016/2 by replacing paragraph 1.2.2. rather than deleting it. Drawing from the recently approved amendment to UN R58 (document GRSG/2015/17), this proposal would amend paragraph 1.2.2. to read, “Vehicles where any LDP (e.g. fixed, removable, foldable, adjustable, etc.) is incompatible with their use on [traffic] roads may be partly or fully exempted from this Regulation, subject to the decision of the Type Approval Authority.”

Updated proposal, revised for clarity, to amend document GRSG/2016/2 by replacing paragraph 1.2.2. rather than deleting it. Drawing from the recently approved amendment to UN R58 (document GRSG/2015/17), this proposal would amend paragraph 1.2.2. to read, “Vehicles where any LDP (e.g. fixed, removable, foldable, adjustable, etc.) is incompatible with their on-road use may be partly or fully exempted from this Regulation, subject to the decision of the Type Approval Authority.”

27. The expert from UK reminded GRSG about the purpose of document ECE/TRANS/WP.29/GRSG/2016/2 (based on GRSG-109-17) amending the scope of the Regulation to ensure that as many vehicles as possible were fitted with a lateral protection device. The expert from CLCCR supported the proposal in principle, but preferred to insert derogations for some niche products (GRSG-110-20-Rev.1). GRSG noted a number of comments.

28. GRSG agreed to resume consideration of this subject at its next session and requested the secretariat to keep ECE/TRANS/WP.29/GRSG/2016/2 and GRSG-110-20-Rev.1 on the agenda as reference documents. Thus, the expert from UK volunteered to prepare a revised document for a final review at the forthcoming GRSG session, taking into account the comments received.

Revised approach to resolving the issues raised in Romania’s proposal GRSG/2015/21 to redefine the measurement criteria for determining appropriate seat spacing. This proposal has been developed collaboratively by Romania, OICA, and CCLCR with respect to discussions held by the type approval authorities of the member states of the European Union (TAAM). The proposal includes the use of a new testing gauge for the H dimension measurement.

5. Recalling the discussion on ECE/TRANS/WP.29/GRSG/2015/21 at the previous GRSG session, the expert from Romania introduced GRSG-110-03 clarifying the requirements on seat spacing and superseding the official document. The expert from OICA introduced GRSG-110-09 amending the provisions on the use of the gaging devices in the case of monitor or display devices mounted at the ceiling of buses and coaches. The expert from Italy presented GRSG-110-21 to align the 05, 06 and 07 series of amendments of UN Regulation No. 107 with the requirements of Supplement 4 to the 04 series of amendments concerning barriers in the gangway and the amount of priority seats in buses and coaches. GRSG adopted the proposals as reproduced in Annex II to the report and requested the secretariat to submit them to WP.29 and AC.1 for consideration at their November 2016 sessions, as draft Supplements to the 04, 05, 06 and 07 series of amendments to UN Regulation No. 107.

Document GRRF/2016/20 proposes to remove certain design restrictions that impede the application of new technologies, especially related to trailer power steering systems and the use of energy from the towing vehicle, including specification of the connector through which electrical energy is supplied in the proposal. Although this proposal was approved in principle at the 80th GRRF session, it was agreed that the proposal would be reviewed at the 81st GRRF to define an open value [X] in paragraph 2.1.1. of Annex 5. It has subsequently been concluded that this change to paragraph 2.1.1. is not needed. Therefore, this proposal removes the change to the paragraph from GRRF/2016/20.

48. The expert from CLEPA recalled, on behalf of CLCCR, the proposal ECE/TRANS/WP.29/GRRF/2016/20 previously adopted by GRRF with a scrutiny reservation. CLCCR reviewed the text in square brackets and proposed to delete it as proposed in GRRF-81-13. GRRF adopted the proposal as amended by Annex V to the report and requested the secretariat to submit it together with ECE/TRANS/WP.29/GRRF/2013/13 to WP.29 and AC.1 for consideration at their June 2016 sessions, as Supplement 5 to the 01 series of amendments to Regulation No. 79.
