37. The expert from OICA introduced GRVA-02-24 (based on ECE/TRANS/WP.29/GRVA/2018/2), proposing to insert in the Regulation some provisions for ACSF of Category C with a two-step Human Machine Interface (HMI) approach. The expert from the Netherlands disagreed with the proposed seven seconds as the time during which the second deliberate action by the driver should take place while this time for the one-step HMI approach (latest time by which an automatic initiation should occur), already in force, is limited to five seconds. The expert from France supported the proposal and showed flexibility on the seven seconds value to reach consensus among CPs. The expert from Germany asked whether this proposal would allow one single vehicle to be equipped with both a one-step HMI and a two-step HMI and how the combination of both would work. GRVA invited OICA to consider the issues raised by the experts and requested the secretariat to distribute the proposal with an official symbol for review at its September 2019 session.
