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.

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.

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.
