Proposal to amend provisions on electronic stability control warnings under braking regulations to allow for activation of the ESC visual warning during a stability-assistance intervention of an electronic steering control. The aim is to avoid separate requirements for brake-actuated and steering-actuated stability assistance that would lead to two visual warnings where only one is appropriate.
89. In ECE/TRANS/WP.29/2018/8, the title, for “Supplement 1 to the 01 series”, read “Supplement 17 to the 00 series”.
8. The expert from OICA introduced GRRF-83-22, proposing clarifications to the provisions related to the stability control optical warning in Regulations No. 13, 13-H and 140. He explained that, to date, braking regulations explicitly permitted the use of the Electronic Stability Control (ESC) flashing symbol for the purpose of showing interventions of systems related to the vehicle stability function (e.g. traction control etc.). He added that with the proposed clarification, it would be clarified that the use of the ESC flashing symbol would be permitted for indicating the intervention of individual steering control for vehicle stability such as Corrective Steering Functions, if related to the vehicle stability function.
9. GRRF agreed to resume consideration of this document while reviewing the proposal on Automatically Commanded Steering Function (ACSF) under agenda item 9.
