53. The expert from the Russian Federation, chairing the IWG on AECS, recalled the detailed consideration of GRSG at its previous session of the new UN Regulation on AECS on the basis of ECE/TRANS/WP.29/GRSG/2017/12. He informed GRSG that the IWG had again reviewed the proposal to remove some editorial inconsistencies. He added that the latter ones have been taken into account in the official document ECE/TRANS/WP.29/2017/132 which was submitted to WP.29 and AC.1 for consideration at their November 2017 sessions. He concluded that further work needed to be done. As Secretary of the IWG on AECS, the expert from OICA introduced the revised justification document (GRSG-111-06-Rev.1) on draft UN Regulation on AECS. He reiterated his concern that Contracting Parties to the 1958 Agreement which intend to apply the Regulation should ensure the necessary infrastructure for the application of the new UN Regulation, once it enters into force.

54. GRSG reconfirmed its adoption of ECE/TRANS/WP.29/2017/132 and agreed to resume consideration on this subject at its forthcoming session, especially on the need for further developments to the new UN Regulation.

44. On behalf of the IWG on AECS, the expert from the Russian Federation presented a draft UN Regulation on AECS (ECE/TRANS/WP.29/GRSG/2016/19) and GRSG-111-06 with a detailed justification for the proposal. He introduced GRSG-111-07 with some further amendments proposed by the IWG on AECS. He drew the attention of GRSG to the limited scope of the new Regulation. He added that several functionalities were not covered by the provisions of the draft UN Regulation such as

1. the communication module functionality and communication antenna functionality unless otherwise prescribed in the Regulation,
2. the additional data to the Minimum Set of Data (MSD) to be convened to Public Service Answering Party (PSAP),
3. the format of the data, the mechanism and logic of data transmission, data exchange protocol, (iv) the operation modes and conditions of transitions between such modes,
4. performance of the test call and test data transfer, the response to protocol commands received from infrastructure and network registration logic, privacy, data protection and personal data processing as well as
5. Periodical Technical Inspection (PTI). These functionalities would have to be resolved or approved on a national/regional level.

45. GRSG welcomed the document and acknowledged the work of the IWG on AECS. GRSG noted a number of comments on the scope of the new Regulation and reviewed the proposal as reflected in GRSG-111-38. The expert from the Russian Federation introduced GRSG-111-13 clarifying that the draft UN Regulation does not apply to AECD/AECS functionality assessment in case of vehicle rollover. The expert from Japan presented study results on the peak pulse in comparison with three crash test methods (GRSG-111-26). He concluded that the corridor of the sled pulse (60g) specified in ECE/TRANS/WP.29/GRSG/2016/19 was severe enough for real world crashes. The experts from the Russian Federation and Switzerland supported that position. The expert from EC explained that his organization had already issued the EU legislation with a pulse peak of 65g and, thus, he would not be in the position to support the proposal. He raised a study reservation to consider in detail the study results of GRSG-111-26. GRSG agreed to keep GRSG-111-26 on the agenda as a reference document.

46. The expert from OICA gave a presentation on the current status of regulatory developments and proposed possible steps forward (GRSG-111-39). He introduced GRSG-111-15 which proposes further amendments to ECE/TRANS/WP.29/GRSG/2016/19 aimed at introducing type approval requirements for Automatic Emergency Call Component (AECC). The proposal received general support.

47. GRSG welcomed GRSG-111-04 which lists ITU recommendations referenced in draft UN Regulation on AECS that specify the speech communication requirements for emergency calls originating from vehicles. The expert from ITU introduced the ITU Conformity Assessment Steering Committee (GRSG-111-40).

48. Finally, GRSG agreed that an extension of the mandate of the IWG on AECS was not necessary and to resume consideration of this subject at its next session in April 2017. GRSG endorsed the following suggestions by the Chair:

1. Experts were invited to send their written comments on the AECC requirements (GRSG-111-15) to the expert from OICA by end of November 2016 at the latest;
2. Experts were invited to participate in a task force meeting organized by OICA and scheduled to be held in January 2017 to discuss the remaining open issues (GRSG-111-38);
3. Contracting Parties were invited to consider, at the highest level, possible solutions to resolve the incoherence of their positions on the pulse peak of 60g versus 65g.
