34. The Chair of GRSG reported on the results of the 124th session of GRSG (for details, see the report in ECE/TRANS/WP.29/GRSG/103).

35. GRSG adopted amendments to nine UN Regulations Nos 67, 110, 105, 125, 121, 158, 162, [166] and [167].

36. GRSG agreed to seek guidance of WP.29 concerning purview/priority of work to be shared with GRVA on Advanced Driver Assistance Systems (ADAS) emergency braking at low speed (Urban Emergency Braking System (UEBS) less than 20 km/h for M2, M3, N2, N3). WP.29 agreed to have a clearer understanding of the direction of work related to the proposal before starting this activity under GRSG or GRVA.

37. Concerning Event Data Recorder (EDR) / DSSAD, the GRSG Chair reported that GRSG sought guidance of WP.29 on the deadline for submission of the proposal:

1. March 2023 session of GRSG and November 2023 session of WP.29 for final adoption; or
2. October 2023 session of GRSG and March 2024 session of WP.29 for final adoption.

38. In the case WP.29 would endorse option (a), GRSG agreed to explore the possibility of organizing a GRSG special session, in case the group would not be in the position to adopt the proposal at its March 2023 session.

39. The representative of the European Union reminded WP.29 that EDRs were set to be mandatory for new types of heavy-duty vehicles under European Union General Safety Regulation and urged to focus on the deadline referred to in (a) to trigger these provisions. The EDR/DSSAD IWG Co-Chair noted that while the IWG was mindful of the pending GSR deadline, that the complexity of issues yet to be resolved, made the suggested deadline in (a) unrealistic as noted at the last GRSG meeting. WP.29 took note of the needs expressed by the European Union, invited GRSG and its IWG to maintain their high pace and report on progress at coming WP.29 sessions.

40. The Chair of GRSG listed potential actions, discussed by GRSG, which would aim to solve inconsistencies between different UN Regulations and UN GTRs related to different versions of the Three-Dimensional H-point machine:

1. Continue to use the H point machine for type approval/certification purposes,
2. Update M.R.1 to include drawings and specifications of the H point machine according to the specifications from SAE J826-1995,
3. Update R.E.3 to include measurement procedures according to ISO 6549:1999 using the upper leg and lower leg setting of the 50th percentile,
4. Update references in all UN Regulations to the latest revision of R.E.3 and to include the same test procedure as in R.E.3 to update UN GTRs and
5. In parallel seek an agreement with SAE International to use the concerned SAE standard, with the support of the representative of the Netherlands.

41. WP.29 endorsed the solution of GRSG and requested the secretariat to coordinate in a consistent way the same approach in GRSP.

42. WP.29 noted that GRSG had re-elected by acclamation Mr. A. Erario (Italy) as Chair for the sessions in 2023 and Mr. K. Hendershot (Canada) as Vice-Chair for the sessions in 2023.

41. The World Forum approved the report of the Chair of GRSG on its 124th session (ECE/TRANS/WP.29/GRSG/103).
