Proposal to revise the terms of reference and rules of procedures for the Informal Working Group on Advanced Emergency Braking Systems. The IWG shall review current regulatory actions and data on Automated Emergency Braking Systems and provide recommendations on future regulatory actions including revisions to UN Regulation No. 152. The IWG shall examine current AEBS regulations worldwide, assess accident situations for passenger vehicles, draft state-of-the-art performance requirements for collision scenarios involving pedestrians at night, investigate regulatory improvements to performance requirements, and investigate feasibility to include updated requirements to avoid false activation of AEBS for light vehicles. The IWG shall deliver complete regulatory text for AEBS for passenger vehicle requirements as revision of UN Regulation No. 152 for the September 2028 session of GRVA at the latest.

For the purposes of type approval under any UN Regulation requiring the verification of the timing of a system intervention, manufacturers shall provide to the approval authority or its designated technical service information on the method by which the initiation of any system intervention can be objectively identified and retrieved, including specific flags, status bits, event codes on in-vehicle networks, or visual indications on screens; clear instructions and all necessary tools for the Technical Service to extract, access and interpret the signal identifying the initiation; documented procedures including corresponding data sources, resolution, and timing accuracy appended to the type approval test report; and, where a visual indication displayed on a screen is used, documented latency between the earliest internal point at which the system initiates the function and the moment the visual indication becomes visible on the screen, expressed as a fixed value with associated uncertainty, with the documented latency value used to correct the observed timing of the screen indication appended to the type approval test report.
