Advanced Emergency Braking Systems

5. The secretariat reminded that Footnote 5 in the table of Annex 3 in the 01 series of amendments to Regulation No. 131 imposed the review of the target speed in cell H2 before 1 November 2021.

6. The expert from Japan presented (GRRF-86-12) a status report of the activities of the Informal Working Group (IWG) on Advanced Emergency Braking Systems (AEBS). GRRF agreed that AEBS for light vehicles should perform when the target is a vehicle, a pedestrian or a cyclist, recognizing that the technology for cyclist detection is still being refined . GRRF agreed to also consider the concern raised by the expert from Sweden on the detection of big animals by AEBS.

7. GRRF also agreed that AEBS for light vehicle should not be included in UN Regulation No. 131, noting that UN Regulation No. 131 is aimed at addressing situations on highways, while AEBS systems for light vehicle would primarily address urban situations.

8. The expert from Germany recalled the purpose of ECE/TRANS/WP.29/GRRF/2017/24 proposing more stringent provisions on automatic reactivation of AEBS. He presented GRRF-86-32 addressing concerns expressed at the September 2017 session on the original proposal. The expert from OICA answered to the proposal (GRRF-86-18). The experts from Nordic Countries supported OICA’s proposal as they are facing user acceptance issues on their market due to false AEBS warnings. GRRF urged the experts from Germany and from OICA to submit a revised proposal for the September 2018 session of GRRF.
