Document GRVA-04-42
26 September 2019

Proposal to allow for higher lateral acceleration limits for Automatically Commanded Steering Functions (ACSF) in executing lane changes. The proposal modifies acceleration limits in the original proposal (GRVA/2019/27) and focuses on the timing for lane changes (e.g., 15-second total duration).

34. The expert from AVERA presented GRVA-04-53, introducing ECE/TRANS/WP.29/GRVA/2019/26, ECE/TRANS/WP.29/GRVA/2019/27 and ECE/TRANS/WP.29/GRVA/2019/28. The presentation contained videos, simulations and fleet data supporting the proposals for amendments to UN Regulation No. 79. The presenters referred to a driving demonstration organized by Tesla in conjunction with GRVA to justify their statements. The proposal received some comments. The contracting parties were not opposed to an evolution of the regulatory provisions based on experience, if the assurance of safety is provided. The expert from AVERE presented revised proposals GRVA-04-41 and GRVA-04-42 aimed at addressing comments received. GRVA noted that some parts of the proposals were also addressed by the proposal submitted by the expert from OICA and agreed to review it.

35. GRVA welcomed the proposal from the expert from the United Kingdom, who volunteered to lead activities on the review of the three AVERE proposals as well as the amendment proposal tabled by OICA in GRVA-04-08 with the aim to prepare a formal proposal until November 2019 in order to meet the deadline for submission of documents for the February 2020 session of GRVA.
