UN R138: Proposal for Supplement 1 to the 01 series of amendments
Proposal to
- exempt hybrid vehicles that do not provide valid test results (e.g., internal combustion engine active under test conditions)
- clarify the text concerning permissible AVAS operating conditions
to differentiate indoor and outdoor facility requirements (e.g., weather station requirement) and- update flowcharts in Annex 3 in line with text.
- add a footnote to the scope to exempt electrified vehicles where the internal combustion engine (ICE) operates under the test conditions
- 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
- clarify under paragraph 6.2.6. that a manufacturer may install an attenuation to enable the system to operate at different sound levels
- split and clarify indoor and outdoor testing specifications under Annex 3 paragraph 2.2. to account for different needs such as a weather station
- amend the flowcharts in the Annex 3 Appendix to better reflect the regulation text
- align the transitional provisions in the 01 series of amendments with the format introduced following Revision 3 of the 1958 Agreement.
