This study compared and assessed camera-monitor systems and conventional exterior mirrors in test drives and static tests under different external conditions. The assessments include the examination of technical aspects and of issues pertaining to the design of human-machine interaction.

The present working document incorporates vehicles with conventional propulsion. To adopt all current propulsion systems, like EV’s, the text is modified accordingly by including a reference to the “vehicle master control switch” in addition to the conventional ignition switch.

This proposal of the IGCMS-II amends the provisions on the category M2 or M3 vehicles with regard to their general construction according Regulation 107 to include vehicles equipped with devices for indirect vision such as camera-monitor devices. A folding seat for use by the crew, in position of use and when folded, may not obstruct the driver’s view on the exterior rear-view mirror. This also applies for the view on the monitor used for camera-monitor devices, if fitted.

This proposal of the IGCMS-II amends the provisions on steering equipment according Regulation 79 to include vehicles equipped with devices for indirect vision such as camera-monitor devices. Various steering effort test provisions depend on the turning circle which currently excludes external mirrors. The text is amended to exclude as well external camera’s for camera-monitor devices. The proposal would replace the reference to rear-view mirrors with the term “devices for indirect vision” to encompass exterior CMS devices.

Proposal to align UN R10 with the amendment to UN R46 that would enable the type approval of camera-monitor systems in place of rear-view mirrors. The amendment would replace the reference to rear-view mirrors with “devices for indirect vision” including CMS.

Proposal to align the UN regulation on frontal impact (UN R94) with the proposed amendment to UN R46 that would enable the type approval of camera-monitor systems in place of rear-view mirrors. The proposal would have exterior CMS treated identically as exterior rear-view mirrors presently are under UN R94.

Proposal to clarify the wording concerning the prohibition on the obstruction of the driver’s view of the monitor and the definition of the monitor size.

Draft proposal to align the provisions of Regulation 26 with the proposed amendments of Regulation 46 (devices for indirect vision) for the replacement of rear-view mirrors by camera monitor systems.

Draft proposal to align the provisions of Regulation 61 with the proposed amendments to Regulation 46 (devices for indirect vision) for the replacement of rear-view mirrors by camera monitor systems.

Draft justifications for eventual inclusion in the amendment proposal submitted to the GRSP.

Draft of the formal proposal (working document) for submission to the GRSP.

Working draft of the CMS regulatory text marked up to show changes incorporated during each CMS II informal group session, including those for review during session 7.
