Proposal to align UN R125 (driver forward field of vision) with the amendments to UN R46 under development to enable the approval of camera-monitor systems as indirect vision devices in place of conventional mirrors.

Text prepared by the International Organization of Motor Vehicle Manufacturers OICA in coordination with the Informal Working Group Camera Monitor Systems (CMS II) to clarify the treatment of camera-monitor systems and similar indirect vision devices under Regulation No. 125. Presently, UN R125 exempts rear view mirrors from the requirements concerning obstructions to the driver’s forward field of vision. This proposal would clarify that rear vision camera-monitor systems benefit from the same exemptions.

Document GRSG/2015/8 proposes to amend the provisions on forward field of vision of drivers in UN R125 to promote and to support the installation of camera-monitor devices on vehicles of category M1. This proposal would clarify that the amendment only applies to regulated devices for indirect vision.

25. The expert from Germany introduced ECE/TRANS/WP.29/GRSG/2015/8 on new provisions for the indirect view within UN Regulation No. 125 (Forward field of vision of drivers) in the case vehicles were equipped with CMS. GRSG noted some comments. The expert from OICA clarified that only the devices for indirect vision covered by UN Regulation No. 46 shall benefit from such provisions (GRSG-108-25). The expert from Germany volunteered to prepare an updated document for consideration at the next GRSG session, taking into account the comments received.

Proposal to modify UN R125 in line with the proposed amendment to UN R46 (indirect vision) that introduces the use of camera-monitor systems (CMS) in place of rear-view mirrors (i.e., document GRSG/2015/2). This proposal is part of a package of proposals to amend the UN Regulations impacted by the amendment to UN R46 and would extend the provisions for rear-view mirrors to CMS devices.

Proposal by the Informal Group on Camera-Monitor Systems (IGCMS-II) to introduce the optional replacement of mirrors of Classes I to IV by camera-monitor systems.

23. Referring to the final report GRSG-108-23, the expert from the Netherlands, chairing the Informal Working Group (IWG) on Camera-Monitor Systems (CMS), informed GRSG that his group had finalized the draft amendments to Regulation No. 46 to introduce the optional replacement of mirrors of Classes I to IV by camera-monitor systems (ECE/TRANS/WP.29/GRSG/2015/2). He added that all ISO standards referred to in the proposed text were accessible for GRSG experts as informal documents GRSG-108-03 and GRSG-108-20. On behalf of the informal group on CMS, he presented GRSG-108-21 incorporating further amendments to ECE/TRANS/WP.29/GRSG/2015/2. He proposed to insert supplementary information on camera-monitor systems of classes I to IV into the existing information documents required for type-approval procedure (GRSG-108-22).

24. GRSG adopted ECE/TRANS/WP.29/GRSG/2015/2, amended as reproduced in GRSG-108-46-Rev.2 (including the modified scope proposed in GRSG-108-17-Rev.1 and adopted under para. 22 above). The secretariat was requested to submit the adopted proposal to WP.29 and AC.1 for consideration at their November 2015 sessions, as draft Supplement 2 to the 04 series of amendments to UN Regulation No. 46.

27. The expert from the Netherlands presented ECE/TRANS/WP.29/GRSG/2015/10 and ECE/TRANS/WP.29/GRSG/2015/11 proposing to align the provisions of UN Regulations Nos. 26 (External projections) and 61 (External projections of commercial vehicles) with the adopted new CMS provisions in UN Regulation No. 46 (para. 24 above). GRSG adopted both documents and requested the secretariat to submit them (together with ECE/TRANS/WP.29/GRSG/2015/2, as amended) to WP.29 and AC.1 for consideration at their November 2015 sessions, as draft Supplement 3 to the 03 series of amendments to UN Regulation No. 26 and as draft Supplement 3 to UN Regulation No. 61 respectively.

Proposal to modify UN R125 in line with the amendment to UN R46 (indirect vision) that introduces the use of camera-monitor systems (CMS) in place of rear-view mirrors. This proposal also ends the temporary exemption permitting CMS device obstruction of driver field of view from 1 September 2021.
