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.

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.
