He explained that the document was summarizing the deliberations of GRVA, so far, on Artificial Intelligence (AI) in the context of vehicle regulations. He added that the document contained the list of statements made by the delegations on this topic. He continued that the document proposed possibilities, in terms of committees, to further discuss this topic and also in terms of documentation, on how to take stoke of the statements received so far. He went through the text of a draft guidance document drafted on the basis of the positions expressed. He asked for comments and input.

8. The expert from France welcomed the document. He stated that such document was necessary. He promised to provide input after the session to the secretariat.

9. The expert from FIA welcomed developments in the field of AI. He welcomed that GRVA took care of it but he noted that most AI were based on interactions with human beings. He wondered how GRVA should consider the involvement of humans in this context. GRVA invited the expert from FIA to provide input on this aspect at the next session, if desired.

10. The expert from Germany welcomed the document as an excellent summary. She added that the document was under review by the experts and that she would send comments to the secretariat.

11. The expert from UK highlighted that AI could have relevance for other WP.29 subsidiary bodies as AI could also impact e.g. emissions.

12. The expert from the USA sought for clarifications about the purpose of this exercise, and what would be delivered, a note, some reporting to WP.29, or a guidance document.

13. The expert from SAE International stressed that discussions in this area needs to stand with proper definitions.

14. The expert from Canada agreed with the expert from SAE International and stressed the importance of definitions before guidance is contemplated.

15. The expert from the Russian Federation advised, on definitions, to first focus on AI as a software that is implemented in an Automated Driving System (ADS), with specific features, affecting safety.

16. The expert from France suggested that a first output under this agenda item should be an information for WP.29 so that WP.29 can then decide on the outcome that should be delivered.

17. GRVA agreed that AI have applications beyond ADAS and ADS and that this should be reported to WP.29.

18. GRVA welcomed the informal document prepared by the secretariat and invited experts to provide input for the preparation of a revised version.

4. Automated/autonomous and connected vehicles:
4. (a) Deliverables of the Informal Working Group on Functional Requirements for Automated and Autonomous Vehicles

20. The expert from the United States of America, Co-Chair of the IWG on Functional Requirements for Automated and Autonomous Vehicles (FRAV), presented the informal group’s status report (GRVA-11-25). He referred to a consolidation of FRAV working documents (GRVA-11-24) that presented current elements of the FRAV discussions. He explained that GRVA-11-24 reflected work in progress, including elements still under review, that this document followed the FRAV framework for safety requirements covering all ADS configurations, intended uses, and limitations on use (such as Operational Design Domain (ODD) constraints). He continued that the framework was based on manufacturer descriptions of each ADS with provisions to ensure uniformity and measurable/verifiable ODD specifications. He detailed that the safety requirements were structured for application to each ADS based on the manufacturer description and that FRAV was pursuing an approach (a) to user safety based on the roles users may play during a given trip (e.g., passenger, fallback user, driver) and (b) to ADS interactions with other road users based on detection of object properties that enable object recognition and classification at a level sufficient to determine the appropriate response(s). He reported that FRAV was first developing safety requirements at a general level and anticipated working in parallel with the IWG on Validation Method for Automated Driving (VMAD) to develop technical specifications for these requirements. He highlighted the close relationship between performance requirements and the scenarios used to assess performance (i.e., the requirements ensure safe ADS navigation of the nominal and safety-critical traffic scenarios developed by VMAD) and in this regard, the increasing FRAV collaboration with VMAD (as expected). He mentioned the corresponding three workstreams on the performance of the Dynamic Driving Task (DDT), interactions with other road users, lighting and the new workstream related to data collection together with the IWG on Data Storage System for Automated Driving (DSSAD)/ Event Data Recorder (EDR). He reported that FRAV had sent initial recommendations to the EDR/DSSAD informal group on data collection for ADS as requested, and that FRAV expected to provide further input, including examples for applying its recommendations. He concluded by mentioning that this work on data collection may also be relevant to the VMAD work on ADS in-service monitoring and reporting.

21. The expert from the United Kingdom of Great Britain and Northern Ireland asked whether means to increase transparency on the workstreams could be identified. He explained that there were many meetings, that were difficult to follow.

22. The expert from the United States of America answered that the group was carefully addressing this point, making sure that the workstreams would not work aside of FRAV. He explained that the workstreams were informal and dynamic, to address specific technical details, and that their work was fully discussed in plenary FRAV sessions.

36. He introduced ECE/TRANS/WP.29/GRVA/2021/20, with recommendations on uniform provisions concerning cyber security and software updates, suitable for the purpose of the Contracting Parties of the 1998 and 1958 Agreements. He explained that no UN Global Technical Regulation was envisaged because of the difficulty to define acceptance criteria, which would depend on how a vehicle is equipped. He stated that these recommendations, covering cyber security and software updates and permitting the use of Regulation No. X Software Identification Number (RxSWIN), can be followed and adapted to national circumstances.

37. He reported on the activities of the group concerning the review of the request by the expert from CEMA to remove vehicle categories S, T and T from the scope of UN Regulation No. 156. He explained, that following a technical discussion, the group confirmed that vehicles of these categories were using Over-the-air Software updates and that the scope of UN Regulation No. 156 was fine. He suggested that the scope of UN Regulation No. 155 could be expanded to vehicles of Categories S, R and T as both regulations went hand in hand.

38. He also reported on group’s activities on ECE/TRANS/WP.29/GRVA/2021/20 following a request for clarification on the transition clauses specified in paragraphs 7.3.1. and 7.3.4. with regards to the extension of type approvals first issued before 1 July 2024 and applied for such extension after that date. He explained that the group developed amendments to (a) the UN Regulation No. 155 (Cyber Security and Cyber Security Management System, and (b) the respective Interpretation Documents for UN Regulation No. 155 (ECE/TRANS/WP.29/2021/59), in order to clarify under which circumstances extensions were possible and which additional information was expected to be provided by the vehicle manufacturer applying for approval.

39. The expert from Canada stated the world of cyber security was very active including on vulnerability assessment tools. He mentioned existing services as suitable mitigation tools. He highlighted that Canada published Transport Canada’s Vehicle Cyber Security Strategy as well as Canada’s vehicle cyber security guidance. He stated that the work of the IWG was not completed.

40. The expert from the United Kingdom of Great Britain and Northern Ireland, Co-Chair of the group, acknowledged that the world of cyber security was evolving, and that regulations and other activities, as those mentioned above, were going hand in hand.

41. The expert from the United States of America proposed that ECE/TRANS/WP.29/GRVA/2021/20 should be kept at GRVA level for the time being.

42. The expert from the European Commission recalled that the document was mandated by the Framework Document on Automated Vehicles and wondered why it should not be transmitted to WP.29.

43. The Secretary of the IWG explained that some elements were missing in the document and that he would try to provide a corrected version as soon as possible.

44. GRVA agreed that there was no urgency and agreed to consider a revised document at its January 2022 session.

49. The expert from Germany asked whether the Cyber Security and Over-the-Air issues (CS/OTA) group was having plans for updating the annexes of the Regulation.

50. GRVA noted that the mandate of the IWG was running until November 2022 and discussed the inclusion of vehicles of Categories S, R and T in the scope of UN Regulation No. 155 and the corresponding timeline as well as the question raised by Germany (para. 49).

51. The expert from Japan suggested that the review of the Regulation would be needed at some point and inquired whether a regular IWG meeting would be needed for the time being.

52. The expert from the European Commission stated that there was no emergency to include vehicles categories S, R and T in UN Regulation No. 155 and that he did not have views on the timeline.

53. The expert from CEMA supported a discussion concerning the vehicles categories S, R and T of UN Regulations Nos. 155 and 156.

54. The secretariat asked whether GRVA would wish to discuss the deletion of the Categories R, S and T from the scope of UN Regulation No. 156. The expert from UK supported that the categories S, R and T would remain in UN Regulation No. 156. He explained that the question was about UN Regulation No. 155. He added that the implementation of the Regulation was a matter of relevance for the Contracting Parties. He supported a discussion on UN Regulation No. 155.

55. The expert from Finland suggested that the categories would belong to the scope of both regulations but that there was no hurry to insert them.

56. GRVA agreed to resume consideration at its twelfth session regarding the scopes of UN Regulations Nos. 155 and 156 with regards to Categories R, S and T.

5. (b) Software updates and Over-the-Air issues

57. GRVA dealt with this agenda item together with agenda item 5(a).

5. (c) Data and vehicle communications

58. The expert from FSD presented GRVA-11-15 (also on behalf of CITA). He recalled the existing regulatory activities on remote access to in-vehicle data within the Motor Vehicles Working Group of the European Commission and within GRVA. He described the current situation with regard to remote access to in-vehicle data and explored, in the case GRVA would be willing to deal with this item, the implications of relying on ISO 20077 (extended vehicle), which only allows data transfer via Business to Business (B2B) transactions. He highlighted that such system would not be appropriate for sovereign use cases, including Market Surveillance Activities and Periodic Technical Inspections. He advocated for a trust centre to be developed that would manage access to in-vehicle data. He based his explanation on an example (DSSAD) and highlighted the importance of the separation of duties in that context and the importance for authorities to get access to these data.

59. The expert from AAPC noted that this matter was touching on EDR/DSSAD. He raised the question: who owns the data? He suggested that access to data would be best managed at regional level. He noted that courts had the right to ask for data.

60. The expert from FIA mentioned that the CITA/FSD presentation was close to what FIA presented at previous sessions.

61. The expert from Norway thanked CITA/FSD for the informative presentation.

62. The expert from Germany asked what was the role and the place of the citizens in the model presented.

63. The expert from FSD answered that the consumers were recognized, and that consent could be managed, being a part of the trust centre role. He answered to the comment from AAPC that the model presented was referring, as an example, to DSSAD but that it was not exclusive. He explained that the trust centre would be a governance tool and that other examples could have been chosen, such as in-service monitoring. He stressed the importance of a trusted storage that is needed for courts as well as all other stakeholders, including authorities and citizens. He also recognized the value of the concept presented by FIA.

64. The expert from FIGIEFA supported the approach presented. She noted the diverging technical aspect but the converging overall goals. She stated that the discussions should continue, also at regional level with the European Commission Directorate-General for Internal Market, Industry, Entrepreneurship and SMEs (DG GROW). Their technical expert mentioned that the technical approach would not be sufficient; both “write” and “read” access and further clarification could be discussed at the European level.

65. The experts from CLEPA and OICA promised to review the presentation in detail and to send comments.

66. GRVA invited the Chair and the secretariat to approach the Committee on the Coordination of Work (WP.29/AC.2). GRVA agreed to resume consideration of this agenda item at its next session to discuss the role of GRVA. GRVA noted that the IWG on EDR/DSSAD could perform a first review of the topic presented by CITA (related to EDR/DSSAD) at one of its next sessions, as time allows.

6. Advanced Driver Assistance Systems and UN Regulation No. 79
6. (a) Advanced Driver Assistance Systems

68. The expert from the Russian Federation, Co-Chair of the Task Force on Advanced Driver Assistance System (ADAS), introduced GRVA-11-16, with a status report of the activities performed by the group. He detailed the activities under the two workstreams on the review of amendment proposals to UN Regulation No. 79 and on the drafting of a new Regulation. He explained that the group was envisaging to develop a new UN Regulation on Dynamic Control Assistance Systems (DCAS), as a subset of ADAS, with a structure derived from the one of UN Regulation No. 157 and incorporating outcomes from the IWG on VMAD concerning audits and tests (including virtual testing). He confirmed that the draft was addressing both the DCAS performance and DCAS interactions with human drivers.

69. The expert from Finland mentioned the excellent work of the group, but was not sure whether the new UN Regulation should address DCAS or ADAS, as the name DCAS could suggest it would also address higher level of automation, as the word “driver” was missing in DCAS. He also raised the importance to involve the Global Forum for Road Traffic Safety (WP.1). The position was also supported by the experts from Sweden and Denmark.

70. The expert from the Russian Federation, Co-Chair of the IWG on ADAS, clarified that the levels of automation envisaged were assistance levels according to the definitions provided in ECE/TRANS/WP.29/1040 and that the group was developing an approval framework for systems around the driver, which would be useful to industry and would clarify the assistance that can be given to drivers.
