UN Regulation No. 46
Indirect Vision Devices

Series of Amendments, Supplements, and Corrigenda

44. The World Forum resumed consideration of the guidance requested by GRSG on the introduction of a concept of Revisions of type approvals in the framework of the 1958 Agreement on the basis of ECE/TRANS/WP.29/2010/111 proposing Supplement 5 to the 02 series of amendments to Regulation No. 46 (Devices for indirect vision) (see ECE/TRANS/WP.29/1087, para. 45). The representative of OICA introduced WP.29-153-27 clarifying the concerns expressed by Japan at the previous session.

45. The Chair of GRE agreed to adopt documents ECE/TRANS/WP.29/2010/111 and WP.29-153-27, however, as the definitions of “revision” and “extension” of type approvals may affect manufacturers of vehicle lighting and light signalling, he asked WP.29 to leave this item including WP.29-153-26, on the agenda of the June session to allow for potential comments from GRE experts. The Chair of GRRF wondered if WP.29-153-26 in seeking clarification on the extensions to type approvals was linked to the proposal by GRSG. WP.29 agreed with the Chair’s suggestion to have a final review of the proposals at the June 2011 session relying on OICA to advise on the relationship between both issues.

45. The World Forum was asked to provide guidance on the introduction of the concept of revisions of type approvals in the framework of the 1958 Agreement on the basis of a proposal for Supplement 5 to the 02 series of amendments to Regulation No. 46 (Devices for indirect vision). The representative of Japan expressed some concerns and the World Forum agreed to continue consideration of this concept for possible application to all Regulations annexed to the 1958 Agreement at its March 2011 session.

28. The expert from the Netherlands presented ECE/TRANS/WP.29/GRSG/2011/22 (superseding GRSG-100-13) proposing the concept of extension in the communication form of Regulation No. 61 (External projections of commercial vehicles). GRSG noted that a concrete proposal (ECE/TRANS/WP.29/2011/152) on this subject was on the agenda of the November 2011 session of WP.29 (see WP.29 report: ECE/TRANS/WP.29/1093, para. 51). GRSG agreed to resume consideration of the matter at its next session on the basis of a revised proposal by the Netherlands, taking into account the final decision of WP.29.

Note: The 03 series of amendments includes the provisions for camera monitor systems.

[Adopted by AC.1.]

Proposal as adopted by the Working Party on General Safety Provisions (GRSG) at its 102nd session to reduce the blind spot on the passenger side of N2 and N3 (medium/heavy commercial) vehicles.

Proposal unanimously adopted.

48. Agenda item 4.8.2, UN Regulation No. 46, document ECE/TRANS/WP.29/2012/87 (see WP.29-158-08):

Paragraph 15.2.1.1.1, the table (rows for vehicles of category N2 and N3), columns of exterior mirrors of Classes IV, V and VI, insert to read (3 times):

Add new paragraphs 21.16 and 21.17, to read:

Document WP.29/2012/87 proposed changes to UN R46 to reduce the blind spot on the passenger side of N2 and N3 (medium/heavy commercial) vehicles as the draft 04 series of amendments to UN R46.

Proposal unanimously adopted.

48. Agenda item 4.8.2, UN Regulation No. 46, document ECE/TRANS/WP.29/2012/87 (see WP.29-158-08):

Paragraph 15.2.1.1.1, the table (rows for vehicles of category N2 and N3), columns of exterior mirrors of Classes IV, V and VI, insert to read (3 times):
“In addition according to paragraphs 15.2.4.5.6 to 15.2.4.5.11 for vehicles with a mounting height of the Class V mirror of not less than 2.4 m (see paragraph 15.2.4.5.12): the required field of vision (paragraphs 15.2.4.5.6 to 15.2.4.5.9) may be viewed using a combination of direct view and indirect vision devices (of Class IV, V, VI).

Add new paragraphs 21.16 and 21.17, to read:

Text as adopted by the Working Party on General Safety Provisions (GRSG) at its 103rd session, proposing to permit the installation on vehicles of a new generation of exterior and interior mirror without housing or holder (i.e., “frameless mirrors”).

Proposal to clarify the transitional provisions of the 03 series of amendments to UN Regulation No. 46, including provisions for extensions of approvals to the 03 series of amendments, for approval of devices to the 02 series, and provisions for aftermarket devices.

Proposal to clarify the provisions on the extended field of vision on heavy goods vehicles across different mirror classes. The text would require assessment of normal and extended fields of vision using a single mirror adjustment and to allow for the loss of up to 10% of the close-proximity field of vision in such configurations. The proposal would also clarify the transitional provisions and provisions for aftermarket devices.

Proposal clarify the scope and to allow for the type approval of camera-monitor systems installed in place of Class I through IV mirrors.

Proposal to clarify that fully integrated surveillance mirrors may be mounted below 2 metres in cases where they are integrated in a housing including one or more Class II or III mirrors.

Proposal to change the latency for scanning a field of vision (total process of scanning, rendering and reset to its initial position) from a maximum of 2 seconds to a maximum of 200 ms. This proposal corresponds to the current state of technology and removes a contradiction within the regulation between paragraphs 6.2.1.2. and 6.2.2.3.4.3. (the latter introduced via supplement 2 to the 04 series of amendments).

Proposal to clarify that overlays may only be used to convey “safety-related rearward vision information.” The proposal addresses confusion regarding circumstances under which the provision of information through overlays is permissible. The proposal also amends the French text. The overall proposal aims to make clear that overlays may convey safety information regarding the rearward environment of the vehicle and are not necessarily limited only to when the vehicle is moving in reverse. The proposal also aims to restrict the information to rear-vision safety. Other information, not related to the rear view, should never appear within the defined field of view. The proposal also corrects the omission of Class VII devices from the communication form described under Annex 3 of the regulation, as previously adopted for Revisions 5 and 6.

114. The Chair of GRSG presented proposals on ECE/TRANS/WP.29/2018/123 to ECE/TRANS/WP.29/2018/126 under agenda items 4.7.4 to 4.7.7, to amend UN Regulations Nos. 46, 67, 105 and 110. The World Forum recommended their submission to AC.1 for voting.

Proposal to correct paragraph 16.1.3.1. as follows: “The minimum and the average magnification factors of the CMS, in both horizontal and vertical directions shall not be lower than the minimum average magnification factors indicated below.” The latter reference to “minimum average” should be deleted since the subsequent text provides the required minimum and average magnification factors.

The proposal also corrects the cross-reference in paragraph 6.3.3.2. where “the test shall satisfy the conditions laid down in paragraph 6.1.3. of this Regulation” should refer to paragraph 6.1.1.3. and aligns the communication form with with the scope of the Regulation regarding vehicle categories (adding category L).

Proposal to clarify the application of provisions, introduce EMC provisions related to UN R10, address the intended use of camera monitor systems, and update transitional provisions.

Proposal to introduce provisions for activation of a “temporary modified view” (such as change in image magnification or resolution) per ISO 16505:2015 to complement the static Class II field of vision using a Camera Monitoring System (CMS).

Proposal to enable the use of small indicative lines to assist the driver in discriminating among two or more fields of vision rendered as a combined continuous image on a display.

Proposal to allow the use of free form mirrors as an alternative to spherical mirrors.

Proposal to

• clarify the diameter of the impact test rig,
• introduce provisions for centre-steered vehicles and corresponding magnification factors and for frameless outside mirrors,
• clarify the possibility of having foldable camera wings,
• exclude Class I CMS camera (mounted on the roof of the vehicle) from the impact test,
• clarify impact positions for the pendulum test,
• remove provisions for surveillance cameras (to be covered under UN R26 and UN R61),
• replace references to “mirror” with “indirect vision device”,
• clarify markings for devices capable of displaying more than one field of vision, and
• clarify positioning of pure Class I CMS.

• clarify the possibility of having foldable camera wings,
• exclude Class I CMS camera (mounted on the roof of the vehicle) from the impact test,
• clarify impact positions for the pendulum test,
• modify the definitions of the “external original surface” of the vehicle and the “impact point” relative to the hammer
• remove provisions for surveillance cameras (to be covered under UN R26 and UN R61),
• replace references to “mirror” with “indirect vision device”,
• clarify markings for devices capable of displaying more than one field of vision, and

Proposal to update the references to the three-dimensional H-point (3-D “H”-point) measurement and calibration procedure (per the update and transfer of specifications from the Consolidated Resolution on the Construction of Vehicles (R.E.3) to Mutual Resolution No. 1 (M.R.1)).

The Working Party on the Transport of Dangerous Goods (WP.15) has noted that problems could arise during the approval of vehicles intended for the carriage of explosive substances and articles (Class 1) for vehicles intended for the carriage of liquids having a flash-point of not more than 60°C. (EX/III and FL vehicles) fitted with a camera monitoring system which complied with the requirements of UN R46.

The European Agreement concerning the International Carriage of Dangerous Goods by Road (ADR) stipulates that the electrical circuits must be broken within 10 seconds after operation of the battery master switch. This might conflict with paragraph 16.1.1. of UN R46 which requires that, after each engine switch-off (intended use), the camera-monitor system remains operational for a period of at least 120 seconds.

This proposal aims to resolve the disparity between UN R46 and requirements for ADS vehicles.

Proposal to update the references to the three-dimensional H-point (3-D “H”-point) measurement and calibration procedure pursuant to updates and transfer of related provisions from the Consolidated Resolution on the Construction of Vehicles (R.E.3) to Mutual Resolution No. 1 (M.R.1).
