Agenda Item 6. (b)

UN Regulation No. 79 (Steering equipment)

GRVA agreed to resume consideration of a proposal for amendments to UN Regulation No. 79, tabled by the expert from Australia, intended to facilitate a consistent approach across all Contracting Parties for Emergency Lane Keeping Systems (ELKS) covering vehicles of categories M₁ and N₁.

GRVA agreed to review the proposal tabled by the experts from CLEPA and OICA, aimed at harmonizing the provisions in UN Regulations Nos. 79 and 157 with the wording in UN Regulation No. 152 (AEBS for M1 and N1) on the conditions for re-instatement of the system at the “initiation of each engine start / run cycle”.

GRVA may wish to be briefed on the outcome of an industry workshop on steer-by-wire.

GRVA may wish to consider any other amendment proposal to UN Regulation No. 79, if available.
