Report prepared by HaskoningDHV Nederland B.V. for the Rijkswaterstaat (Dutch Ministry of Water, Traffic & Environment).

Final report by Royal HaskoningDHV as commissioned by Rijkswaterstaat (Dutch infrastructure ministry) to assess in actual practice under which conditions the traffic control measures are detected by the FWC/AEBS currently in common use.

Proposal to

1. delete the requirement limiting the speed reduction during the collision-imminent warning phase
2. define a time range for the warning function to ensure adequate warning at lower speeds
3. introduce specific requirements for the achievable speed reduction for the cases of dry roads and wet roads
4. introduce speed reduction requirements at 70 km/h and 40 km/h for dry and wet roads, respectively
5. restructure provisions under “Specifications” and “Test Procedure” to enable testing at different speeds
6. prevent unintended AEBS deactivation
7. delete certain exemptions (to be addressed at national levels)

Germany proposed, in document GRRF/2017/24, to require automatic reactivation of a manually deactivated automatic braking system. One concern with the proposal invoked the need for prolonged deactivation under certain circumstances, such as when a vehicle is fitted temporarily with a snow plow. This proposal would explicitly require AEBS to be capable of detecting a blocked sensor (already implicit in the regulation) such that AEBS would not reactivate in such cases.

OICA counter-proposal to address the German concern over manual deactivations of AEB systems. The original document (GRRF/2017/24) proposed automatic reactivation of the AEBS when the vehicle speed exceeds 30 km/h. OICA proposes reactivation after 15 minutes of continuous operation at a speed above 70 km/h.

Report on the development of AEBS requirements for light vehicles, including a note on the intention to seek GRRF approval for a new regulation on M₁/N₁ vehicle AEBS separate from the current UN R131 on heavy-duty vehicle AEBS.
