29. The expert from Japan, Co-Chair of the IWG on Event Data Recorder (EDR) / Data Storage Systems for Automated Driving (DSSAD), presented GRVA-14-39, recalling the mandate of the group, providing an overview of the group’s activities and listing the activities of the group since the May 2022 session of GRVA. He explained that the group clarified the primary objective of DSSAD, which was to record data to evaluate and monitor the overall safety performance and identify when ADS was in control of vehicles. GRVA agreed with the group’s suggestion that, while data obtained from DSSAD could be used for other purposes including liability, this was not the primary goal or objective of the DSSAD requirements.

30. He reported that the Co-Chairs of the IWG on EDR/DSSAD held discussions with the Co-Chairs of the Special Group on Automated Lane Keeping System (ALKS) and OICA to review ECE/TRANS/WP.29/2022/59/Rev.1 and replace ‘Abortion of Lane Change Procedure’, that is to be recorded, by ’Abortion of Lane Change Manoeuvre’, as proposed in ECE/TRANS/WP.29/GRVA/2022/16 under agenda item 4(d).

31. GRVA reviewed GRVA-14-40 (Inventory of best ADS storage practices (Review of the existing national / regional activities and a proposed way forward for DSSAD)) and adopted GRVA-14-40/Rev.1, a version including updates by the expert from France. GRVA requested the secretariat to submit it to WP.29 for information at its November 2022 session.
