Download in .pdf format Download in .docx format

Proposal by the experts from the Informal Working Group (IWG) on Advanced Emergency Braking Systems (AEBS) for vehicles of Categories M1 and N1 to introduce provisions for car-to-bicycle scenario in a single step approach. (Alternatively, the IWG has prepared proposals for a two-step approach to introducing the new requirements. GRVA is therefore requested to make a decision on whether car-to-bicycle should be introduced in a single step or in a two-step approach.)

Working Party on Automated and Connected Vehicles | Session 7 | 21-25 Sep 2020

52. The expert from Japan, Co-Chair of the IWG on Advanced Emergency Braking Systems (AEBS) for M1 and N1 vehicles, reported (GRVA-07-70) on the outcome produced by the group. He introduced ECE/TRANS/WP.29/GRVA/2020/26 with clarifications regarding, among others, response to failure, false reaction avoidance, sensor misalignment and automatic deactivation. He also introduced ECE/TRANS/WP.29/GRVA/2020/27 including provisions for the approval of AEBS covering Car to Bike scenarios (“1-step” approach) and mentioned the alternative proposals by OICA (“2-step approach).

53. The expert from OICA presented alternative proposals: ECE/TRANS/WP.29/GRVA/2020/28 and ECE/TRANS/WP.29/GRVA/2020/35. They include transitional provisions for specific cases with regards to the Car to Bike scenarios (GRVA-07-12, GRVA-07-72 and GRVA-07-74). He explained that the provisions developed by the group included lower speeds than those managed by existing vehicles meeting the corresponding test in New Car Assessment Test Programmes. He added that covering lower speeds would require modifying existing vehicles equipped with such systems, to cover larger sensor field of view.

54. GRVA adopted ECE/TRANS/WP.29/GRVA/2020/26 as amended by GRVA-07-09 (see Annex V of the session report) and requested the secretariat to submit it as supplement to the 00/01 series of amendments to UN Regulation No. 152 (AEBS) for consideration and vote by WP.29 and AC.1 at their March 2021 sessions.

55. GRVA adopted ECE/TRANS/WP.29/GRVA/2020/27 as amended by GRVA-07-10 (see Annex VI of the session report), ECE/TRANS/WP.29/GRVA/2020/28 as amended by GRVA-07-11 (see Annex VII) and ECE/TRANS/WP.29/GRVA/2020/35 as amended by GRVA-07-53 (see Annex VIII). GRVA requested the secretariat to submit them for consideration, decision on the 1-step or 2-step approach in November 2020 and vote by WP.29 and AC.1 at their March 2021 sessions.

56. GRVA noted that ECE/TRANS/WP.29/GRVA/2020/25 had been incorporated in the documents above.

75. WP.29 discussed the way forward for amendments to UN Regulation No. 152 and the two alternatives prepared by GRVA (WP.29-182-19). WP.29 requested the secretariat to prepare a draft new 02 series of amendments to UN Regulation No. 152, based on ECE/TRANS/WP.29/GRVA/2020/27 for consideration and vote at the March 2021 session. WP.29 invited GRVA to review that document at its December 2020 session.
