TF AVSR Comments on document ECE/TRANS/WP.29/GRE/2023/9/Rev.3

Proposal is to define common rules while leaving the choice to
countries to adopt them or not. These rules must in particular make it possible to
automatically cut off the work lamps in circulation to avoid glare and make traffic
safer

In order to harmonise requirements among different installation Regulations, the SLR Officers offered to draft a proposal for Reg. 48 to clarify that devices not allowed in the Regulation are prohibited (in line with Par. 5.17. of Reg. 53).

Proposal to introduce provisions to enable the approval of reversing light projections.

Proposal to address vehicles of categories R or T with a width more than 2.55 m and of category S with a width more than 3 m as well as to allow using reflective materials as an alternative to retro-reflectors.

Proposal from the EMC informal group to update electromagnetic radiation immunity provisions, address automatic emergency call systems (AECS) and automated driving systems (ADS), update references to standards, and effect editorial improvements.

Proposal from the Autonomous Vehicles Signalling Reguirements (AVSR) task force to update the text of UN R48 to enable application to vehicles equipped with an Automated Driving System (ADS).

Proposal prepared by the experts from the Task Force on Automated Vehicle Signalling Requirements (TF AVSR). Proposal aim to introduce vehicles with a driving system, which controls its operation or may be operated by driver support features or automated driving features or by an Automated Driving System (ADS).

Proposal to introduce an alternative configuration for the light emitting diode replacement (LEDr) light source category H11.

Proposal to align the requirements in UN R48 with updated requirements in UN R149 (UN R48 currently only refers to a light source or light-emitting diode (LED) module(s) for dipped beam (paragraph 6.2.9.) and to light sources of the lighting units for an adaptive front-lighting system (AFS) (paragraph 6.22.9.) while the latest updates to the 01 series of UN R149 requires the communication form to indicate whether the total objective luminous flux of one or more light source(s) or light source module(s) for a dipped beam exceeds 2,000 lumens). This proposal replaces the term “LED module” with “Light source module” and modifies wording to adapt to the introduction of “matched pair” requirements for headlamps and AFS.

Proposal to align the requirements for off-road vehicles passing-beam vertical inclination between the 06, 07, 08 series and the 09 series of amendments to UN R48.

Proposal to avoid exceeding the aggregate maximum intensity of the main-beam headlamps (430,000 cd) by removing the double requirement for a sum of reference marks and a sum of maximum luminous intensities which risks generating large rounding errors when the maximum luminous intensities are summed up.

Proposal to correct and clarify the communication form.

Proposal to clarify the measurement of the quality of the “cut-off”.

Proposal to clarify the markings. Some countries and regions refer to the requirements of the 00 series of amendments to UN R149, or to older regulations. In order to avoid the redundant burden to mark the symbols of both the 00 and 01 series on the lamp (e.g., “HCR” or “HR and C”), the proposal would allow for consistency of the symbols between the 00 and the 01 series of amendments. UN R149 also includes passing-beam requirements designed to provide symmetrical “cut-off” line: the proposal introduces examples in Annex 13.

Proposal to enable the approval under UN R74 of a front and rear indicator that can be activated simultaneously, to allow the installation of optional direction indicators at national level on bicycles (including vehicles with a maximum design speed not exceeding 25 km/h), and to introduce a new symbol “-“ under UN R148 between the symbols indicating the functions of the device in order to differentiate a device which fulfils the requirement of a front indicator of category 11 and a rear indicator of category 12 that cannot be activated simultaneously from one that can.

Proposal to address lamp positioning on wider vehicles of categories R, S, and T, to allow using reflective materials as an alternative to retro-reflectors, to clarify provisions (including failure detection), and to make editorial improvements.

Proposal is to define common rules while leaving the choice to countries to adopt them or not. These rules must in particular make it possible to automatically cut off the work lamps in circulation to avoid glare and make traffic safer.

Proposal to clarify that only light-signalling devices may incorporate an illuminated logo.

Proposal to introduce new light emitting diode (LED) light source categories LW7A and LW7B.

Proposal with the aim to allow the projection of a pattern for predicted trajectory.

Proposal aims to correct a wrong reference for the determination of the approval marking size.

This proposal intends to rectify the inconsistency between UN Regulation No. 149, (both original version and 01 series of amendments) and the frozen UN Regulations (namely UN Regulations Nos. 98, 112 and 123) by aligning the measurement points for the mechanical deterioration test. The deletion of measuring point HV, for the passing-beam headlamps, does not change any technical requirement since there are no photometric values specified for point HV in the UN Regulation No. 149, both in the original version and in the 01 series of amendments.

Proposal aims to correct COP Tables. the maximum luminous intensity of Segment BLL for Class V (see Tables 6 and 7) was intentionally changed from 880 cd (as in UN Regulation No. 123 and in the original series of amendments of UN
Regulation No. 149) to 625 cd (as in the 01 series of amendments to UN Regulation No. 149). The purpose of this modification was to align the value with Class C but, by mistake, this change was not reflected in the COP Tables 25 and 26

Proposal aims to amend failure detection and signalisation requirements to reflect technological progress in multiple light sources. This amendment proposes to include in UN Regulation No. 149 different provisions allowing that a failure signal is only triggered when a significant change in the beam is detected and ensuring that the most suitable failure provision can be applied. Proposal for a Supplement to the 06, 07, 08 and 09 series of amendments to UN Regulation No. 48
