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.

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.
