Discussion paper regarding future noise and tyre work priorities.

Proposal to introduce a definition for “Electronic” to mean a principle of operation by electric or electro-magnetic force with amplifier and speaker or resonator in order to address new technologies enabling a driver-actuated audible signal of the presence of a vehicle in a dangerous traffic situation.

Proposal to address non-negligible differences in sound performance in cases where COP tests are carried out under conditions that differ from those used for the granting of the type approval. The proposal introduces conditions, procedures, and corrections to be applied to L_urban to account for the difference in test conditions.

Proposal to:

1. add a footnote to the scope to exempt electrified vehicles where the internal combustion engine (ICE) operates under the test conditions
2. clarify the intention of paragraph 6.2.:
   • that AVAS may be operational outside the specified speed ranges (e.g., in the USA where the speed range extends to 30 km/h),
   • align maximum sound with UN R51.03 ASEP, and
   • explicitly specify that the AVAS may function even when the ICE is running
3. clarify under paragraph 6.2.6. that a manufacturer may install an attenuation to enable the system to operate at different sound levels
4. split and clarify indoor and outdoor testing specifications under Annex 3 paragraph 2.2. to account for different needs such as a weather station
5. amend the flowcharts in the Annex 3 Appendix to better reflect the regulation text.

Proposal to correct an inconsistency in document GRB-68-22 (adopted along with GRB/2018/7 and submitted for consideration at the March 2019 WP.29 session as WP.29/2019/6) regarding the ASEP exemption conditions for vehicles with variable gear ratios or automatic transmission with non-lockable gear ratios.
