Introduction (for information)
The purpose of this Regulation is to provide the provisions for means of rear visibility and detection that would improve the driver’s awareness of vulnerable road users behind vehicles when reversing. UN Regulation No. 46. provides the provisions for indirect vision of motor vehicles. This Regulation expands driver’s awareness behind vehicles when reversing. Therefore, some requirements of this Regulation may be satisfied by devices complying with UN Regulation No.46.
This Regulation cannot cover all the traffic conditions and infrastructure features in the type approval process; this Regulation recognises that the performances required in this Regulation cannot be achieved in all conditions (vehicle speed and condition, weather conditions, and traffic scenarios etc. may affect the system performances).
1. Scope
This Regulation applies to:
1.1. Approval of devices for means of rear visibility defined in Part I intended to be fitted to vehicles of category M and N.
1.2. Approval of vehicle installation of means of rear visibility or detection defined in Part II if fitted to vehicles of category M and N.
1.3. At the request of the manufacturer, Contracting Parties may grant approvals under Parts I and II to vehicles of other categories and devices for fitting to such vehicles.
1.4. The following vehicles of category M and N shall be exempted from this Regulation:
Vehicles where installation of means of rear visibility or detection is incompatible with their on-road use may be partly or fully exempted from this Regulation, subject to the decision of the Type Approval Authority.
1.5. If a vehicle has multiple device(s), the manufacturer shall designate the device that meets the provisions of the regulation.

Overlays shall display only rearward driving-related visual information or safety-related information. Overlays for other purposes of information in the required field of vision are not allowed.
Manually activated overlays are allowed, only when the driver needs to activate a rearward driving-related function or safety-related function (e.g. cleaning of the lens or activation of trailer hitch view) or requires specific information in such an environment. The driver may have an option to close the overlay.
16.1.1.3. Deactivation
The rear-view image shall remain visible during the backing event until either, the driver modifies the view, or the vehicle direction selector is no longer in the reverse position or the backing event is finished.
Modifying the view means to switch to any other camera views.
The view can be manually switched off when the vehicle is not moving rearward.
The system may be switched off when the vehicle detects a coupling by means of a coupling device.
16.1.1.4. Automatic change of view
When there is a risk of collision, the field of view may change and focus on the collision area. It shall be demonstrated to the Technical Service that this change of view increases the safety.
When the vehicle is not driving straight, the field of view may change following the vehicle trajectory.
16.1.2. Operating readiness (System availability)
Non-operation of the system shall be recognizable to the driver (e.g. RVCS failure by, i.e. warning indication, display information, black screen, absence of status indicator). The information for the driver shall be explained in the operator's manual.
16.1.2.1. Response time
The rear-view image meeting the requirements described in 15.2. shall be provided within a maximum of 2.0 seconds after start of the backing event, when tested according to paragraphs 2. of Annex 9.

17. Requirements for detection systems
17.1. System activation
The system shall be activated when the backing event starts. If proper functioning cannot be effected, either the system shall automatically shut off or the driver shall be able to deactivate the system manually.
The detection system shall remain active as long as either the vehicle direction selector is in the reverse position or the backing event is not ended.
In case the vehicle can detect coupling with a coupling device, the system may be switched off.
17.2. Driver interface and information presentation strategy
17.2.1. The system shall have at least two kinds of information signal selected from audible, optical, and haptics.
17.2.1.1. As long as one information signal remains active, the driver may de-activate the other information signals.
17.2.2. Audible information
When an object is detected in the rear horizontal area as described in paragraph 1.3. of Annex 10. while the reverse gear is selected/engaged, audible information in accordance with ISO 15006:2011 shall be given.
In presenting audible information, the distance to the target may be identified by two or more acoustic signals. These acoustic signals, differentiating distances and detection widths, may be indicated by changing the frequency of the intermittent sound. A faster intermittent sound or continuous sound shall be used as the distance becomes closer.
17.2.3. Duration of signalling
Signalling for an object shall last as long as the object is detected and shall end when the object is no longer detected or when the system is deactivated.
To reduce the driver's discomfort, the audible signal can be automatically suspended temporarily after a certain time set by the manufacturer has elapsed, provided that the system remains activated. If, while the audible signal is automatically suspended temporarily, the distance to the object becomes shorter, the audible signal shall be automatically resumed. If the distance to the object becomes longer, the audible signal may remain suspended.
17.2.4. Optical information
In the case optical information is placed on a monitor used for other information such as meter cluster display or other displays, overlay is allowed and shall comply with the overlay requirements of the RVCS in 16.1.1.2. of this Regulation.
17.2.5. Operating readiness (System availability)
Non-operation of the system shall be recognizable to the driver (e.g. Detection system failure by, i.e. warning indication, display information, black screen, absence of status indicator). The information for the driver shall be explained in the operator's manual.
17.3. Performance of object detection
17.3.1. Response time
At least one of the audible or haptic information signals that meets the requirements as described in 17.2., shall be given to the driver within a maximum of 0.6 seconds after the start of the backing event, when tested according to paragraph 2. of Annex 10.
17.4 The effectiveness of the detection system shall not be adversely affected by magnetic or electrical fields. This shall be demonstrated by compliance with the technical requirements and transitional provisions of UN Regulation No. 10, 05 series of amendments or any later series of amendments.
18. Modifications of the vehicle type and extension of approval
18.1. Every modification of the vehicle type shall be notified to the Type Approval Authority which approved the vehicle type. Type Approval Authority shall then either:
(a) Decide, in consultation with the manufacturer, that a new type approval is to be granted; or

Test method for determining reflectivity
1. Definitions
1.1. CIE standard illuminate A:1[10] Colorimetric illuminate, respecting the full radiator at T68 = 2,855.6 K.
1.1.2. CIE standard source A:1 Gas-filled tungsten filament lamp operating at a correlated colour temperature of T68 = 2,855.6 K.
1.1.3. CIE 1931 standard colorimetric observer:1 Receptor of radiation whose colorimetric characteristics correspond to the spectral tristimulus values
x̅ (λ), γ̅ (λ), z̅ (λ)
(see table).
1.1.4. CIE spectral tristimulus values:1 Tristimulus values of the spectral components of an equi energy spectrum in the CIE (XYZ) system.
1.1.5. Photopic vision:1 Vision by the normal eye when it is adapted to levels of luminance of at least several cd/m2.
2. Apparatus
2.1. General
The apparatus shall consist of a light source, a holder for the test sample, a receiver unit with a photodetector and an indicating meter (see Figure 1), and means of eliminating the effects of extraneous light.
The receiver may incorporate a light-integrating sphere to facilitate measuring the reflectance of non-flat (convex) mirrors (see Figure 2).
2.2. Spectral characteristics of light source and receiver
The light source shall consist of a CIE standard source A and associated optics to provide a near-collimated light beam. A voltage stabiliser is recommended in order to maintain a fixed lamp voltage during instrument operation.
The receiver shall have a photodetector with a spectral response proportional to the photopic luminosity function of the CIE (1931) standard colorimetric observer (see table). Any other combination of illuminate-filter-receptor giving the overall equivalent of CIE standard illuminate A and photopic vision may be used. When an integrating sphere is used in the receiver, the interior surface of the sphere shall be coated with a matt (diffusive) spectrally non-selective white coating.
2.3. Geometrical conditions
The angle of the incident beam (Ɵ) should preferably be 0.44 ± 0.09 rad (25 ± 5°) from the perpendicular to the test surface and shall not exceed the upper limit of the tolerance (i.e. 0.53 rad or 30°). The axis of the receptor shall make an angle (Ɵ) with this perpendicular equal to that of the incident beam (see Figure 1). The incident beam upon arrival at the test surface shall have a diameter of not less than 13 mm (0.5 inch). The reflected beam shall not be wider than the sensitive area of the photodetector, shall not cover less than 50 per cent of such area, and as nearly as possible shall cover the same area segment as used during instrument calibration.
When an integrating sphere is used in the receiver section, the sphere shall have a minimum diameter of 127 mm (5 inch). The sample and incident beam apertures in the sphere wall shall be of such a size as to admit the entire incident and reflected light beams. The photodetector shall be so located as not to receive direct light from either the incident or the reflected beam.
2.4. Electrical characteristics of the photodetector-indicator unit
The photodetector output as read on the indicating meter shall be a linear function of the light intensity of the photosensitive area. Means (electrical and/or optical) shall be provided to facilitate zeroing and calibration adjustments. Such means shall not affect the linearity or the spectral characteristics of the instrument. The accuracy of the receptor indicator unit shall be within ±2 per cent of full scale, or ±10 per cent of the magnitude of the reading, whichever is the smaller.
2.5. Sample holder
The mechanism shall be capable of locating the test sample so that the axes of the source arm and receptor intersect at the reflecting surface. The reflecting surface may lie within or at either face of the mirror sample, depending on whether it is a first surface, second surface or prismatic "flip" type mirror.
3. Procedure
3.1. Direct calibration method
In the direct calibration method, air is used as the reference standard. This method is applicable for those instruments, which are so constructed as to permit calibration at the 100 per cent point by swinging the receiver to a position directly on the axis of the light source (see Figure 1).
It may be desired in some cases (such as when measuring low-reflectivity surfaces) to use an intermediate calibration point (between 0 and 100 per cent on the scale) with this method. In these cases, a neutral density filter of known transmittance shall be inserted in the optical path, and the calibration control shall then be adjusted until the meter reads the percentage transmission of the neutral density filter. This filter shall be removed before reflectivity measurements are performed.
3.2. Indirect calibration method
The indirect calibration method is applicable in the case of instruments with fixed source and receiver geometry. A properly calibrated and maintained reflectance standard is required. This reference standard should preferably be a flat mirror with a reflectance value as near as possible to that of the test samples.
3.3. Flat mirror measurement
The reflectance of flat mirror samples can be measured on instruments employing either the direct or the indirect calibration method. The reflectance value is read directly from the indicating meter.
3.4. Non-flat (convex) mirror measurement
Measurement of the reflectance of non-flat (convex) mirrors requires the use of instruments which incorporate an integrating sphere in the receiver unit (see Figure 2). If the instrument-indicating meter indicates ne divisions with a standard mirror of E per cent reflectance, then, with a mirror of unknown reflectance, nx divisions will correspond to a reflectance of X per cent, in accordance with the formula:

A "spherometer" similar to the one described in Figure 1 of this annex having the indicated distances between the tracing pin of the dial gauge and the fixed legs of the bar is used.
1.2. Measuring points
1.2.1. The principal radii of curvature shall be measured at three points situated as close as possible to positions at one-third, one-half and two-thirds of the distance along the arc of the reflecting surface passing through the centre of this surface and parallel to segment b, or of the arc passing through the centre of the reflecting surface which is perpendicular to it if this arc is the longer.
1.2.2. Where, owing to the size of the reflecting surface, it is impossible to obtain measurements in the directions defined in paragraph 2.1.2.2.2. of this Regulation, the Technical Services responsible for the tests may take measurements at the said point in two perpendicular directions as close as possible to those prescribed above.
2. Calculation of the radius of curvature "r"
"r" expressed in mm is calculated from the formula:
Place the test objects at the locations specified in (a) to (h) and illustrated in Figure B. Measure the distances shown in Figure B from a test object to another test object or other object from the cylindrical centre (axis) of the test object as viewed from above. Each test object shall be oriented so that its axis is vertical.
(a) Place test objects A, B, and C so that their centres are in a transverse vertical plane that is 0.3 m to the rear of a transverse vertical plane tangential to the rearmost surface of the vehicle.
(b) Place test object B so that its centre is in a longitudinal vertical plane passing through the vehicle's longitudinal centreline.
(c) Place test objects D, E, and F so that their centres are in a transverse vertical plane that is 1.5 m to the rear of a transverse vertical plane tangential to the rearmost surface of the vehicle.
(d) Place test object E so that its centre is in a longitudinal vertical plane passing through the vehicle's longitudinal centreline.
(e) Place test objects G, H, and I so that their centres are in a transverse vertical plane that is 3.35 m to the rear of a transverse vertical plane tangential to the rearmost surface of the vehicle.
(f) Place test object H so that its centre is in a longitudinal vertical plane passing through the vehicle's longitudinal centreline.
(g) Place test objects A, D, and G so that their outermosts are in a longitudinal vertical plane tangential to the left-side outermost surface of the vehicle.
(h) Place test objects C, F, and I so that their outermosts are in a longitudinal vertical plane tangential to the right-side outermost surface of the vehicle.
Mechanical coupling devices and luggage racks located on the rear of the vehicle shall be disregarded.

In the case of the head/neck joint centre (J) is not compatible for the vehicle seat configuration, adjust the driver's seat to the midpoint of the longitudinal adjustment range. If the seat cannot be adjusted to the midpoint of the longitudinal adjustment range, the closest adjustment position to the rear of the midpoint shall be used.
(c) Draw an imaginary horizontal line between Mf and a point vertically above J, defined as J2.
(d) Rotate the imaginary line about J2 in the direction of the rear-view image until the straight-line distance between Mf and the centre of the display used to present the rear-view image required in this standard reaches the shortest possible value.
(e) Define this new, rotated location of Mf to be Mr (eye midpoint rotated).
3.1. Measurement procedure.
(a) Locate a 35 mm or larger format still camera, video camera, or digital equivalent such that the centre of the camera's image plane is located at Mr and the camera lens is directed at the centre of the display's rear-view image.
