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.
