Proposal to address inconsistency between UN R51 noise limits and AVAS sound levels under UN R138.

64. The representative from Switzerland introduced GRPE-86-05 to inform GRPE on new requirements during PTI tests regarding particulates number measurement in the country. GRPE noted the presentation from the representative from Switzerland.

Proposal by expert from Switzerland to limit the maximum sound level of an “AVAS” and reduce superfluous noise pollution.

13. The expert from Switzerland proposed to prohibit operation of the acoustic vehicle alerting system (AVAS) outside the specification speed range from 0 km/h up to and inclusive 20 km/h (GRBP-74-02). The experts from Germany, ISO and OICA (GRBP-74-28) commented on this proposal. GRBP agreed to revert to this issue at the next session.

121. On behalf of the Task Force on Reverse Warning Sound (TF-RW), working under the Group of Experts on Noise and Tyres (GRBP), the expert from Switzerland introduced the status report of the TF-RW given at the 73rd session of GRBP (GRSG-121-14). He explained that the document dealt mainly with noise issues but also contained safety related aspects relevant for the work of GRSG on slide 13, concerning reverse acoustic warning devices. The expert informed GRSG that the TF-RW had changed the designation of Device(s) for reversing motion to Devices for the means of rearward vision and detection, which would have repercussions on the text of UN Regulation No. 158 that was developed by the IWG on VRU-Proxi.

122. The expert from Switzerland invited GRSG experts to deliver any comments with respect to the information provided to the Chair of the TF-RW (Mr. Hiroyuki Houzu – houzu@ntsel.go.jp) or the Secretary of the TF-RW (Mr. Manfred Klopotek – manfred.klopotek@scania.com). He informed GRSG that the next meeting of the TF-RW would take place on 29 April 2021, while the next GRBP session was scheduled for September 2021.

123. GRSG welcomed the information provided by the expert from Switzerland on behalf of the TF-RW and invited interested parties to submit comments through their representatives at the TF-RW.

Revised safety considerations for activities other than driving undertaken by the driver in a vehicle when its automated driving system is engaged.

26. The expert from Switzerland reported on the recent meeting of the Task Force (TF) on reverse warning issues under the Working Party on Noise and Tyres (GRBP) (GRSG-116-14). He added that TF had proposed amendments on a “pause switch” for reverse warning sound devices which would be permitted if other safety devices (e.g. camera monitor systems) were activated. GRSG welcomed the information and agreed on the need to coordinate this subject between GRBP and GRSG to avoid overregulation of these devices. The Chair invited IWG on awareness of Vulnerable Road Users proximity in low speed manoeuvres (VRU-Proxi) to further consider this subject and to report back to GRSG at its next session in October 2019.

This document proposes a draft text for a resolution on “activities other than those related to driving” that the driver of a vehicle equipped with an automated driving system could undertake when the automated driving system is engaged.

24. The expert from Switzerland presented an update (GRPE-76-08)to his presentation at a previous session of GRPE (GRPE-75-08) on manipulations on EURO V and VI trucks by aftermarket suppression of AdBlue injection . GRPE invited the expert from Switzerland to inform GRPE of new developments if any.

25. The expert from the European Automobile Manufacturers Association (ACEA) informed GRPE about a workshop held in Brussels on this matter. He offered to share information on the outcome of this workshop.
