Proposal to permit the use of virtual testing as an alternative methodology to the physical tests. This approach requires the preliminary assessment of the methodology to be used.
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.
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.
