49. The Chair of GRRF recalled the activities done by the IWG on ACSF and proposed to postpone the discussion on LKAS (ECE/TRANS/WP.29/GRRF/2015/2 and GRRF-79-04) to make sure that the findings of the informal group could be reflected when working the technical provisions for LKAS. The expert from France recalled that the work on LKAS had a high priority and invited GRRF to reflect on whether a discussion on the submitted documentation should take place at this session. The experts from Germany and OICA agreed that the proposal produced by the SIG on LKAS was of a high quality but noted that some definitions should be aligned with those of ACSF. Therefore, GRRF agreed to defer the discussion to the September 2016 session. GRRF noted that LKAS were considered as discontinuous corrective steering, while ACSF would cover systems similar to LKAS but performing continuously. GRRF agreed that the boundaries of these systems needed clarification. GRRF requested the IWG on ACSF to work on the boundary definitions. GRRF agreed to resume consideration of this item at its nest session.
