Working Party on Automated and Connected Vehicles | Session 14 | 26-30 Sep 2022
Agenda Item 4. (c)
Deliverables of the Informal Working Group on Event Data Recorder / Data Storage System for Automated Driving

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.

32. The expert from OICA introduced GRVA-14-29, highlighting the implications concerning the absence of harmonized requirements in UN Regulation No. 157 (ALKS), Chapter 8 (DSSAD) regarding data availability, access and retrieval. He also mentioned that some Contracting Parties sought to require storing additional data elements (e.g. for location) which were neither included nor mandated by the regulation. He invited GRVA to consider harmonizing these requirements. The expert from the United States of America, Co-Chair of the IWG on EDR/DSSAD, confirmed that the IWG did not discuss this matter.
