UN R131: Proposal to amend document GRRF/2017/24
Document GRRF-86-32
13 February 2018

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.
