Previous Documents, Discussions, and Outcomes
7. | Advanced Emergency Braking System

90. The expert from OICA presented GRVA-16-22 on virtual testing for AEBS and mentioned GRVA-15-19 for reference. She stated that industry supported the use of simulation and that the simulation validation should be based on the IWG on VMAD outcome on this topic adapted to AEBS to foster harmonization.

91. The expert from Germany recalled the initial discussions on this topic. He explained that such discussion would now require addressing methodology, metrics and repetitions. The expert from France volunteered to organize a one-day workshop on the topic of AEBS virtual testing. The experts from Germany, UK, CLEPA and OICA welcomed the initiative and stated their interest in participating in the workshop.

92. GRVA requested the secretariat to distribute GRVA-15-19 with an official symbol at the next session.

7. | Advanced Emergency Braking System

104. The expert from France presented GRVA-15-20 introducing GRVA-15-19, with an amendment proposal to UN Regulation No. 152, aimed at introducing provisions for computer simulation of dynamic tests. He explained the history of the proposal. The expert from Japan commented that real driving conditions had to be considered in this context and that the validation requirements for AEBS would potentially require more physical tests than currently required.

105. GRVA reviewed the draft consolidations of UN Regulation No. 152 prepared by the secretariat (GRVA-15-50 and GRVA-15-51) and provided comments.

106. GRVA agreed to keep ECE/TRANS/WP.29/GRVA/2022/24 (proposal for a new UN Regulation for Urban Emergency Braking System) as well as GRVA-15-19 and GRVA‑15‑20 (AEBS virtual testing) on the agenda for its next session.

4. (b) | Deliverables of the Informal Working Group on Validation Methods for Automated Driving

26. The expert from Japan, Co-Chair of the IWG on VMAD, presented GRVA-14-45 with a brief review of the group’s deliverables until June 2022, information regarding the change of the leadership of the VMAD subgroup four, suggestions for deliverables during the two years provided by the mandate extension by WP.29, and a report of the activities since the May 2022 session of GRVA (elaboration of GRVA-14-16, organization of future activities of the four subgroups, and the preparation of the suggestion for deliverables until June 2024). He listed the open issues addressed by each subgroup, he presented the proposed deliverables until June 2024 and he offered suggestions of the leadership team regarding the collaboration with the IWG on FRAV. He announced the invitation by Japan for FRAV and VMAD meetings in December 2022, including a joint session.

27. The experts from France, the Netherlands, and the United Kingdom of Great Britain and Northern Ireland asked for clarifications. GRVA endorsed the status report of the IWG on VMAD.

28. GRVA considered and endorsed GRVA-14-16, including amendments to ECE/TRANS/WP.29/2022/58 (Guidelines for Validating Automated Driving System).
