40. The expert from Japan, Co-Chair of the IWG on AEBS presented GRVA-02-28 with a status report on the activities of the group drafting a new UN Regulation with provisions applicable to vehicles of category M1 and N1 and introduced the corresponding proposal in ECE/TRANS/WP.29/2019/5. He presented the key performance requirements defined for so called vehicle-to-vehicle and vehicle-to-pedestrians AEBS. He mentioned that some provisions were contained in square brackets indicating that decisions by GRVA were needed, e.g. the provisions for manual AEBS deactivation and the definition of performance requirements for vehicle-to-bicycle systems.

41. GRVA discussed provisions allowing for the manual deactivation of an AEBS. The expert from Australia informed that according to their survey, 93 per cent of respondents answered that they never deactivated their AEBS. GRVA, taking into account the risks in case of a misalignment of sensors, agreed to include provisions allowing manual deactivation on the basis that the provisions in the proposal ensured that the process required more than one action to complete.

42. GRVA reviewed the proposal and agreed with the text as reproduced in GRVA-02-39-Corr.1.

43. GRVA requested the secretariat to submit the proposal as amended in para. 42 as draft UN Regulation on Uniform provisions concerning the approval of motor vehicles with regard to the Advanced Emergency Braking System (AEBS) for M1 and N1 vehicles for consideration and vote by WP.29 and the Administrative Committee AC.1 at their June 2019 sessions.

46. The expert from OICA introduced GRVA-02-22, proposing amendments to ECE/TRANS/WP.29/GRVA/2019/5. GRVA recommended that the proposal be reviewed by the IWG on AEBS and that this proposal would either be included in the submission of the IWG for the September 2019 session or be submitted as a separate proposal for review in September 2019, if no consensus would be reached on this proposal by the IWG on AEBS.

36. The expert from EC, Co-Chair of the IWG on Advanced Emergency Braking Systems (AEBS) presented GRVA-01-10 with a status report on the activities of the group on the drafting of a new UN Regulation with provisions applicable to M1 and N1 vehicles as reproduced in GRVA-01-02. He presented the key performance requirements defined for so called vehicle-to-vehicle and vehicle-to-pedestrians Advanced Emergency Braking (AEB) systems and highlighted the open issues discussed by the group on provision for manual AEB deactivation and the definition of performance requirements for vehicle-to-bicycle systems.

37. The expert from UK, supported by the expert from the Netherlands, questioned the proposed value of the maximum differential test speed (42 km/h) that targets collision avoidance. He suggested 50 km/h instead of 42 km/h. He expressed doubts that a staged approach for vehicle-to-pedestrian and vehicle-to-bicycle AEB systems would be appropriate. The expert from OICA justified the value of the maximum differential speed for collision avoidance noting that Euro NCAP was requesting less than this value and justified the staged requirements especially for vehicle-to-bicycle AEBS systems because of the ongoing development process of such systems.

38. The expert from Canada suggested to specify performance-based requirements for all aspects to be tested, including the adhesion criteria of the track surface used for testing. GRVA noted the existing relevant precedent in UN GTR No. 3 and UN Regulation No. 78 and the corresponding value proposed in the draft.

39. The expert from Italy mentioned the risk related to false positive AEB system activation and the need of a manual AEBS deactivation function. The experts from Germany and UK expressed support for provisions on automatic deactivation function in limited cases. They disagreed with the proposal for provisions allowing the manual deactivation of AEB systems.

40. The Chair highlighted the provisions related to the AEBS performance outside of the testing conditions.
