8. The expert from Germany, Secretary of the Informal Working Group (IWG) on Automatically Commanded Steering Function (ACSF), presented the status report of the group GRVA-05-25, introducing the content of GRVA-05-07, proposing the text for a new UN Regulation on Automated Lane Keeping Systems (ALKS) with empty sections as placeholder for the work prepared by the IWG on Validation Methods for Automated Driving (VMAD) and the IWG on Event Data Recorder (EDR) / Data Storage Systems for Automated Driving (DSSAD). GRVA reviewed in detail GRVA-05-07 and sought consensus on provisions in square brackets.

9. The expert from OICA introduced GRVA-05-46 proposing amendments to paragraph 2.1.1. and GRVA-05-45 explaining the need for lane change allowance in ALKS minimum risk or emergency manoeuvres. The expert from UK supported this position and stated the need to allow these lane changes. GRVA could not agree to allow lane changes in the absence of corresponding provisions at this stage, but will continue the discussion.

10. The expert from Japan, Co-Chair of the IWG on EDR / DSSAD reported on the activities of the group on DSSAD for ALKS. GRVA reviewed in detail GRVA-05-31, with draft DSSAD provisions to be inserted in the draft UN Regulation on ALKS.

11. The expert from Germany introduced GRVA-05-36 presenting motivations for the cut-in requirements for ALKS.

12. The GRVA Vice-Chair, Co-Chair of the IWG on VMAD, informed GRVA on the relevant activities of the group. He provided an overview of a draft Appendix 1 to Annex 4 to the draft UN Regulation on ALKS (GRVA-05-19), for which comments from the Automotive Industry were received. He informed on the process to finalize the documents from the group for this session, agreed during a virtual meeting organized by the secretariat on 12 February 2020 (lunchtime). He commented that, although the ALKS related documents were still in a review process by the IWG, he could explain the content, in case GRVA would wish so, e.g. from the viewpoint of interface, integrity and consistency with the other ALKS documents tabled for review during this session. GRVA welcomed this offer to introduce the purpose of document.

13. The expert from Japan provided an overview of the content in the draft Appendix 1 to Annex 4 (GRVA-05-62). The expert from the Russian Federation commented that the relationship between the requirement in the main text and scenarios in the Appendix should be clarified. The expert from the European Commission stated that the parameters in paragraph 5.2.5.2. of the main text and parameters in the Appendix should be consistent.

14. The expert from the European Commission gave an overview of the proposed Annex 4 for the UN Regulation on ALKS (GRVA-05-18). He raised the question, whether introducing in-use reporting was in line with the provisions of the 1958 Agreement. The secretariat stated that he was not aware of any provisions in the Agreement that would prevent such report.

15. The expert from Germany clarified upon request that, in their view, the same Technical Service should perform the evaluation in draft Annex 4 and perform the tests prescribed in draft Annex 5.

16. The Secretary introduced GRVA-05-37 on behalf of the Vice-Chair (China). He agreed to look for the requested clarifications and to send them to the expert from China.

17. GRVA requested the Secretary to consolidate the ALKS, DSSAD and VMAD documents (GRVA-05-07-Rev.1). GRVA discussed on this basis open items such as the terms in the formula in paragraph 5.2.5.2. (GRVA-05-44), the parameters to be registered by DSSAD, the content of Appendix 1 to Annex 4 etc. The Secretary produced two other revisions in the course of the week, which were used by GRVA to build consensus. The outcome of the session on ALKS is reflected in GRVA-05-07-Rev.3. GRVA agreed to use this version in preparation of the sixth GRVA session.

18. The expert from the United States of America, Co-Chair of the IWG on Functional Requirements for Automated and Autonomous Vehicles (FRAV) summarized the group’s work (GRVA-05-40 and GRVA-05-41). He noted that FRAV has held two full meetings contiguous with VMAD and with more than 100 experts. He highlighted the group’s concern to use accurate terms. The group discouraged the use of “autonomous” as misleading and uses “Minimal”, not “Minimum”, Risk Manoeuvres (MRM) because an MRM responds to road conditions and best available solutions. In addition to avoidance of injury or death and compliance with traffic laws, the group noted additional aspects such as behaviour consistent with safe and fluid traffic flows and attention to economic consequences such as destruction of property. He reported that the group had identified automated vehicle configurations that fall outside the category definitions of Special Resolution S.R.1. He also suggested improvements to the Framework Document on Automated Vehicles (FDAV) would be soon necessary and presented the group’s consensus on high-level requirements. He noted unallocated elements of the FDAV (i.e. vehicle maintenance and inspection, consumer education and training, crashworthiness and compatibility, and post-crash Automated Vehicle (AV) behaviour) pertinent to functional safety. He announced planned meetings in Paris (April 2020) and California (September 2020).

19. GRVA discussed the proper use of “Operational Design Domain” versus “Operational Domain”. The expert from the Russian Federation expressed support in the FRAV activities based on the terminology defined by SAE International. The experts from CEN and SAFE also expressed support. The IWG on FRAV announced that detailed discussion would continue during the next meetings.

20. The experts from the European Commission and OICA noted the importance to also involve the Global Forum on Road Traffic Safety (WP.1) on terminology and also to inform them on other relevant GRVA activities.

21. The expert from Japan, Co-Chair of the IWG on VMAD, presented GRVA-05-23 informing on the outcomes of the IWG according to FDAV. He commended the collaboration between IWGs on FRAV and VMAD. He recalled the outcome of the group regarding the ALKS activities. He highlighted the ongoing work on existing and upcoming assessment/test methods of automated driving. He announced the next steps for the group and the next meetings scheduled in 2020.

He mentioned that the revised proposal entailed a recent proposal from Germany and the European Commission (paragraphs 5.3.1.-5.3.3.) in square brackets. He recalled that the TF was planning to deliver further documents accompanying the UN Regulation: a resolution and an interpretation document. He stated that these documents would be further elaborated during the next session of the TF and would distillate the learnings of the test phase in 2019. He informed GRVA that the work on a UN Global Technical Regulation (GTR) had to start.

26. The expert from Japan introduced GRVA-05-20 proposing amendments to paragraph 7.3.8. on the use of cryptographic modules.

27. The expert from the European Commission introduced GRVA-05-22, aimed at clarifying the consequences of the Cyber Security Management System certificate expiration.

28. The expert from Japan introduced GRVA-05-13, expressing strong objections to the proposed paragraphs 5.3.1.-5.3.3. establishing prerequisites to the granting of type approvals not in line with the 1958 Agreement and posing a sovereignty risk. The expert from the Russian Federation expressed a similar position and proposed to draft an alternative proposal.

29. The expert from France introduced, GRVA-05-29 proposing an alternative to the proposed paragraphs 5.3.1.-5.3.3. as well as amendments proposal for paragraph 7.4 and Annex 5.

33. The expert from FIGIEFA introduced GRVA-05-15, proposing a process flow for national/regional authorities to define objective minimum compliance criteria for the UNECE cybersecurity regulation and a way forward for aftermarket issues.

34. GRVA reviewed in detail GRVA-05-05, having in mind the presentations received (paragraphs 26-32 above).

  1. GRVA discussed the scope of the draft Regulation (keeping vehicles of Categories S, R, T, O in square brackets).
  2. GRVA discussed GRVA-05-17 and agreed to keep the proposed paragraph 1.4.
  3. GRVA agreed that the Regulation and the 1958 Agreement would not be prescribing the mutual recognition, among Contracting Parties, of CSMS (and Software Update Management System) certificates.
  4. The expert from Singapore requested clarifications concerning the reporting obligations according to the draft Regulation and wondered whether any reporting would only be shared among the Contracting Parties of the 1958 Agreement. The Co-Chair of the TF explained that the current draft did not impose reporting on existing cyber security threats. He explained that there were already information sharing platforms such as Automotive Information Sharing and Analysis Center (AutoISAC) in the United States of America. GRVA invited the TF to address the question raised.
  5. GRVA resumed discussion on the paragraphs 5.3.1.-5.3.3. The expert from the Russian Federation explained that provisions regarding the competencies of Technical Services should be introduced in Schedule 2 to the 1958 Agreement. He added that GRVA-05-42 was not enough and that not trusting Approval Authorities was not a good idea, as it would be time consuming and expensive. He stated that the Database for Exchange of Type Approval documentation (DETA) could have a useful role to play, that the TF could be entitled to learn from type approvals and propose relevant Regulation amendments to GRVA, as necessary, and he proposed the corresponding regulatory wording (GRVA-05-51). The expert from the Republic of Korea stated that these paragraphs could be misused. The expert from CEN proposed an alternative procedure based on the so-called common criteria approach and referred to WP.29-179-28 and WP.29-179-29. The TF Co-Chair noted that the common criteria approach was not complete. The expert from FIA introduced GRVA-05-16. GRVA requested the TF to provide comments on this document. GRVA noted to availability of GRVA-05-02 reproducing ISO/SAE DIS 21434 addressing aspects of the draft Regulation but not the mutual recognition aspect.

He mentioned the support provided by the expert from the United Kingdom. The experts from Sweden and France provided comments. The experts from Denmark, Finland, the Netherlands and Norway expressed concerns. The expert from the Netherlands explained that the dynamics problems reported by the manufacturer, member of AVERE, were not due to the provisions in the Regulation but were due to design choices made by this manufacturer. The experts from the European Commission, Korea and United Kingdom and Northern Ireland supported the proposals; the expert from OICA, too. The expert from the Russian Federation proposed alternative proposals (GRVA-05-59) improving the text. The expert from the United Kingdom proposed GRVA-05-57 aimed at addressing the comments expressed by the expert from Sweden. GRVA reviewed all revised proposals produced by the expert from AVERE during the week but remained divided. GRVA agreed to review a revised proposal at the sixth session of GRVA, if time allows.

44. The Chair of GRVA noted the division of GRVA on this matter. He proposed that GRVA performs a general review of the Regulation at its September 2020 session.
