Excerpts from session reports related to this document
AEBS/LDWS | Session 15 | 26-27 May 2011

J presented the document AEBS/LDWS-15-07 and explained the lack of consistency of requiring the performance of row 1 for vehicles below 8 tons equipped with pneumatic braking system, but requiring the performance of row 3 for the same vehicles equipped with hydraulic/AOH braking system. By document AEBS/LDWS-15-07, J proposed to apply the requirement of row 3 to all vehicles below 8 tons, whatever their braking system.

The Chair found premature to provide a position on this.

CLEPA pointed out that the N2 vehicles equipped with AOH and pneumatic braking system are of low production volume, and that changing their performance requirements as proposed by J would be difficult to manage on series production.

The Chair recalled that this item was not part of the mandate of the informal group from GRRF-70, and suggested that the interested parties provide a written contribution for the GRRF session of September 2011 (71st session).

J stated that they withdrew their reservation per footnotes 4 (document AEBS/LDWS-15-01) & 5 (AEBS/LDWS-15-02).

Conclusion:
- footnotes 4 & 5 (reservation from Japan toward light M2/N2 vehicles) withdrawn.
- If still interested, Japan is urged to table a relevant document to GRRF-71 in order to generate a debate about the consistency of the requirements for light vehicles

- OICA to present a consistent proposal for non-pneumatic suspension vehicles
- No progress achieved by AEBS/LDWS-15 towards vehicles of categories M2, N2 < 8 tons
- D to decide whether presenting a proposal along the lines of document AEBS/LDWS-15-04 (“deceleration phase”)
- J to decide whether presenting a proposal along the lines of document AEBS/LDWS-15-07
