47. The expert from Japan, on behalf of the Co-Chairs of the IWG on Automatically Commanded Steering Function (ACSF), reported on the outcome of the sixteenth session of IWG on Automatically Commanded Steering Function (ACSF) held on 23-25 January 2018 in Japan (GRRF-86-20-Rev.1). He explained that the group sought for guidance from GRRF on the proper way to address ACSF of Categories B2 and [C2]. GRRF agreed that the Category B2 shall be considered in the context of SAE level 3 or 4 as a first priority. GRRF recognised the interest from industry on an additional option for Category C (C2) and noted that the industry may work separately on this. The expert from Japan stated that, as a second priority, GRRF could also develop provisions for ACSF of Category B2 in the context of SAE level 2. GRRF reviewed in detail the presentation and provided recommendations to the IWG on ACSF on the basis of GRRF-86-20-Rev.1 as reflected in GRRF-86-36. Noting the ambitious deadline for the group and the number of tasks, GRRF’s recommendations included among others the establishment of tasks forces that would work through Web Conferencing in order to make progress before the next session of the IWG on ACSF scheduled in April 2018. GRRF also identified bodies that could develop provisions on transversal issues, not necessarily in the remit of GRRF under the current mandate. GRRF agreed that its Chair would consult GRSG on regulatory activities for Data Storage Systems for Automated Driving (DSSAD).
