Agenda Item 5. (d)
Automatically Commanded Steering Function

32. The expert from Japan, on behalf of the Co-chair of the IWG on Automatically Commanded Steering Function (ACSF), introduced GRVA-02-35, containing a status report on the activities of the IWG. He mentioned the consensus reached by the group so far on: Automated Lane Keeping System (ALKS) activation criteria, driver presence provisions, transition demand provisions, minimum risk manoeuvre and emergency manoeuvre considered in parallel with the transition demand provisions. He also mentioned the challenge related to a vehicle not implementing all driver inputs when an ALKS was activated (e.g. in the case of unintended action by the driver), that should be discussed with WP.1. The Chair of GRVA noted that there was a concern that the minimum risk manoeuvre should not automatically result in a vehicle stopping in a live traffic lane.

33. The expert from Spain asked how to verify the activation criteria related to the vehicle driving on roads where pedestrians and cyclists are prohibited at the time of Type Approval. The expert from Germany answered that one technical solution could imply inspecting the maps used by the system.

34. The secretariat asked whether maps would be in the scope of the Regulation. The expert from OICA stated that maps belong to the technical solutions being part of the designs of the system, implying that Regulations on maps would be undesired design requirements. The expert from ITU stated that maps would have to be certified in the future in case maps would serve as redundancy for safety reasons. He also mentioned that maps could have other purposes, e.g. helping Advanced Emergency Braking Systems (AEBS) to eliminate false positive activations on stationary objects and that therefore map providers would have to be fully liable for their products. He offered to provide GRVA with an overview of map development.

35. The expert from France introduced ECE/TRANS/WP.29/GRVA/2019/9 based on GRRF-86-13 proposing clarifications of the Annex 8 testing provisions. The proposal received some comments from Japan, France, Germany and OICA. The expert from France agreed with the suggestion of GRVA to submit a revised proposal with more data for consideration at the September 2019 session. The experts from Japan, Germany and OICA were invited to share with GRVA their test data, supporting their positions.

36. The expert from France introduced ECE/TRANS/WP.29/GRVA/2019/10, proposing clarifications to the tall-tell requirements for Corrective Steering Function (CSF), Emergency steering Function (ESF) and ACSF. GRVA adopted the proposal as amended and reproduced in Annex III. GRVA requested the secretariat to submit Annex III to the report as draft Supplement 1 to the 03 series of amendments to UN Regulation No. 79 to WP.29 and the Administrative Committee of the 1958 Agreement (AC. 1) for consideration and vote at their June 2019 sessions.

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.
