Proposal to extend the scope of UN R155 to include all vehicles of Category L.

Proposal to align the UN R155 Interpretation Document with the proposal to extend the scope of UN R155 to Category L vehicles.

Proposal to correct a misalignment between the transitional provisions for the new 06 series of amendments to UN R78 and the General Guidelines for Transitional Provisions in UN Regulations.

Proposal to expand the scope of the Regulation to include all Category L and O vehicles if fitted with an electronic control unit.

The European Union, the recently proposed EU Cyber Resilience Act (CRA) will introduce a set of horizontal requirements aimed at strengthening cyber resilience for products across a large number of sectors. While the CRA is a significant legislative initiative, its generic nature might not fully address the specific needs of the automotive industry, in particular for L-category vehicles. UN Regulation No. 155 is already available, proven for the automotive industry, and fully compatible with the EU CRA requirements, making it a more suitable and focused solution for these vehicles.

Proposal to allow using the state-of-the-art test track from the latest standard ISO 10844:2021.

3. The experts from IMMA and ISO tabled amendments that allowed the use of the latest standard ISO 10844:2021 test track (ECE/TRANS/WP.29/GRBP/2023/14, ECE/TRANS/WP.29/GRBP/2023/15). The expert from France proposed to complement these amendments with the phasing out of ISO 10844:2014 compliant test track (GRBP-78-19). GRBP invited IMMA and ISO to revise their proposal for consideration at the next session.

Proposal to provide industry guidelines on anti-tampering provisions for Non-Original Replacement Exhaust Silencing Systems (NORESS) in UN Regulation No. 92.

12. The expert from IMMA presented a draft document for reference with the industry guidelines on antitampering provisions for Non-Original Replacement Exhaust Systems (NORESS) (ECE/TRANS/WP.29/GRBP/2023/17). Various experts were in support of the guidelines and stressed the need for regular updating in the future. GRBP adopted the document and requested the secretariat to issue it as a document of reference on the dedicated webpage. As a next step, GRBP agreed to study the possibility of integrating the guidelines, in a suitable language, into UN Regulation No. 92.

41. The expert from IMMA introduced a draft document for reference with industry guidelines on the antitampering provisions for Non-Original Replacement Exhaust Systems (NORESS) in UN Regulation No. 92 (GRBP-77-20). GRBP experts generally supported the document and made several suggestions for improvement. GRBP agreed to revert to this issue at the next session in order to update the document and later publish it as a document of reference on the GRBP website.

120. The expert from the Netherlands presented GRVA-15-29 introducing ECE/TRANS/WP.29/GRVA/2023/4, an amendment proposal to UN Regulation No. 78 aimed at inserting requirements for Complex Electronic Control Systems and aligned with those for passenger cars. He recalled the context of the proposal tabled, following the adoption of brake light activation criteria for automatically commanded braking functions at the last session. He announced that the alignment (GRVA-15-41) of the proposed text with those developed for UN Regulation No. 13 would be performed in a second step.

121. The expert from United Kingdom of Great Britain and Northern Ireland presented GRVA-15-41, proposing amendments to ECE/TRANS/WP.29/GRVA/2023/4 and aimed at introducing the new provisions for the audit of electronic control systems that have been developed for UN Regulation No. 13 and its Annex 18 (see GRVA-15-08).

122. Following discussion, GRVA adopted ECE/TRANS/WP.29/GRVA/2023/4 as amended by GRVA-15-57 and requested the secretariat to submit it as a proposal for the 06 series of amendments to UN Regulation No. 78 (braking of Category L vehicles) to WP.29 and AC.1 for consideration and vote at their June 2023 sessions.

1. Proposal to amend the 04 and 05 series of UN R41 and the 02 series of UN R63 to allow use of the latest state of the art ISO 10844 test track.
2. ISO has updated the ISO 10844 standard to reduce track-to-track variability caused by differing interpretations and implementations of the technical requirements. The tyre/road contribution to the overall sound performance of a motorcycle is lower compared to cars.
3. The improvements from the ISO 10844:2014 to the 2021 version would not result in a need for updating the surface for L-category test tracks: Updating the ISO 10844 reference would have negligible impact on the measurement procedure and measurement results.
4. If however the ISO reference in the L-category noise regulations would be updated without maintaining the current ISO 10844:2014 as an option, IMMA sees a potential risk of tracks needing recertification, creating administrative burden with no practical benefit.
5. If later on, the tracks would need re-surfacing anyway (e.g. due to wear), then these can be built and certified according to ISO10844:2021. Because of the above, IMMA would like to allow certification with the tracks complying to either ISO10844:2014 or ISO10844:2021.
6. This proposal takes the opportunity to introduce proposals for additional corrections in R41/04 and R41/05 as specified below:
   • Supplement 9 to the 04 series of amendments to UN Regulation 41 introduced a new paragraph 12.4, needing to renumber the (former) paragraphs 12.4 to 12.9 (WP.29/2021/4). Due to this renumbering, the reference to paragraph 12.7 in Annex 6 footnote a, and Annex 7 paragraph 2.6 is no longer correct and should be replaced by a reference to paragraph 12.8.
   • With the introduction of the 05 series of amendments the Transitional Provisions were rewritten and footnote a of Annex 6 became obsolete.

4. The experts of IMMA and ISO proposed to include a reference to the latest standard ISO 10844:2021 test track in UN Regulations Nos. 41 and 63, while keeping reference to the previous version ISO 10844:2014 (GRBP-77-02). GRBP generally supported this proposal and invited IMMA and ISO to prepare an official document for consideration at the next session.

Proposal to complete the additional sound emission provisions’ table of the communication form in the 05 series of amendments to UN R41 to avoid oversight in data collection and entries.

3. The expert from IMMA tabled a proposal that aimed to complete the additional sound emission provisions’ table in the communication form of the 05 series of amendments to UN Regulation No. 41 (ECE/TRANS/WP.29/GRBP/2023/6). GRBP adopted the proposal and requested the secretariat to submit it for consideration and vote at the June 2023 sessions of WP.29 and the Administrative Committee of the 1958 Agreement (AC.1) as draft Supplement 2 to the 05 series of amendments to UN Regulation No. 41.

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.

106. The expert from IMMA presented ECE/TRANS/WP.29/GRVA/2022/26, introducing provisions for the type approval of automatically commanded braking systems. The experts from France, Germany, Italy, Japan, the Netherlands, Spain and the United Kingdom of Great Britain and Northern Ireland supported the proposal. The expert from Canada noted that automatically commanded braking systems might surprise riders and might have unintended consequences. He inquired whether the safety of these systems would be covered elsewhere. The expert from IMMA explained that the safety requirements were included in the proposal in GRVA-14-09.

107. The expert from the Netherlands introduced GRVA-14-09, prepared together with the expert from IMMA. He explained that the proposal was aimed at introducing a complex electronic annex on the model of the one in other braking regulations.

108. The expert from Canada noted that such annex was based on audit requirements, without pass/fail requirements. The expert from IMMA acknowledged that a discussion under the 1998 Agreement would require measurable pass/fail criteria.

109. The expert from France and from the United Kingdom of Great Britain and Northern Ireland supported the aim of the proposal.

110. GRVA adopted ECE/TRANS/WP.29/GRVA/2022/26 and requested the secretariat to submit it as a supplement to the 05 series of amendments to UN Regulation No. 78 to WP.29 and AC.1 for consideration and vote at their March 2023 sessions.

111. GRVA requested the secretariat to distribute GRVA-14-09 with an official symbol at the next GRVA session. The expert from IMMA confirmed, upon request by the secretariat, that it was a proposal for a new 06 series of amendments.
