FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international

co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and

in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,

Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their

preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with

may participate in this preparatory work. International, governmental and non-governmental organizations liaising

with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for

Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all

interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence between

any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.

5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent

rights. IEC shall not be held responsible for identifying any or all such patent rights.

5 Field of view
5.1 General

The field of view of the system is the visible area displayed by the composite images (i.e. from

the multiple cameras composing the system) or the image captured by any single camera that

is then converted and displayed. If the target of the application of this system is to replace an

existing type approval that is required for vehicular equipment, it shall follow the respective

regulation. For example, the FOV shall capture the respective FOV as defined in UN Regulation

No. 46 (classes I to VI) if the system is intended to be used in such an application. The

compulsory or optional FOV shall follow the requirement as specified in the table under

paragraph 15.2.1.1.1 in UN Regulation No. 46.
5.2 Class I FOV

The field of vision shall be such that the driver can see at least a 20 m wide, flat, horizontal

portion of the road centred on the vertical longitudinal median plane of the vehicle and extending

from 60 m behind the driver's ocular points to the horizon. Class I FOV and an example of the

displayed view conforming to this FOV are shown in Figure 2. See Annex A for an example of

a simultaneous display with a class III FOV.

5.3 Class II FOV

The field of vision shall be such that the driver can see at least a 5 m wide, flat, horizontal

portion of the road, which is bounded by a plane which is parallel to the median longitudinal

vertical plane and passing through the outermost point of the vehicle on the driver's side of the

vehicle, and extends from 30 m behind the driver's ocular points to the horizon. In addition, the

road shall be visible to the driver over a width of 1 m, which is bounded by a plane parallel to

the median longitudinal vertical plane and passing through the outermost point of the vehicle

starting from a point 4 m behind the vertical plane passing through the driver's ocular points.

The corresponding text is valid on the passenger side. Class II FOV and an example of the

displayed view conforming to this FOV are shown in Figure 3.

For composite images of left and right cameras, non-continuous images shall be clearly

separated from each other. The image of the right side field of view shall be presented to the

right of the longitudinal vertical plane through the ocular reference point. The image of the left

side field of view shall be presented to the left of the longitudinal vertical plane through the

ocular reference point.

The field of vision shall be such that the driver can see at least a 4 m wide, flat, horizontal

portion of the road, which is bounded by a plane parallel to the median longitudinal vertical

plane and passing through the outermost point of the vehicle on the driver's side of the vehicle,

and extends from 20 m behind the driver's ocular points to the horizon. In addition, the road

shall be visible to the driver over a width of 1 m, which is bounded by a plane parallel to the

median longitudinal vertical plane and passing through the outermost point of the vehicle

starting from a point 4 m behind the vertical plane passing through the driver's ocular points.

The corresponding text is valid on the passenger side. Class III FOV and an example of the

displayed view conforming to this FOV are shown in Figure 4. See Annex A for an example of

a simultaneous display with a class I FOV.

For composite images of left and right cameras, non-continuous images shall be clearly

separated from each other. The image of the right side field of view shall be presented to the

right of the longitudinal vertical plane through the ocular reference point. The image of the left

side field of view shall be presented to the left of the longitudinal vertical plane through the

ocular reference point.

5.5 Class IV FOV

The field of vision shall be such that the driver can see at least a 15 m wide, flat, horizontal

portion of the road, which is bounded by a plane parallel to the median longitudinal vertical

plane of the vehicle and passing through the outermost point of the vehicle on the driver's side

and which extends from at least 10 m to 25 m behind the driver's ocular points. In addition, the

road shall be visible to the driver over a width of 4,5 m, which is bounded by a plane parallel to

the median longitudinal vertical plane and passing through the outermost point of the vehicle

starting from a point 1,5 m behind the vertical plane passing through the driver's ocular points.

The corresponding text is valid on the passenger side. Class IV FOV and an example of the

displayed view conforming to this FOV are shown in Figure 5.

For composite images of left and right cameras, non-continuous images shall be clearly

separated from each other. The image of the right side field of view shall be presented to the

right of the longitudinal vertical plane through the ocular reference point. The image of the left

side field of view shall be presented to the left of the longitudinal vertical plane through the

ocular reference point.

Figure 5 – Class IV FOV and example of display view
5.6 Class V FOV

The field of vision shall be such that the driver can see a flat horizontal portion of the road along

the side of the vehicle, bounded by the following vertical planes:

• The plane parallel to the median longitudinal vertical plane of the vehicle which passes

through the outermost point of the vehicle cab on the passenger's side.

• In the transverse direction, the parallel plane passing at a distance of 2 m in front of the

plane mentioned in the paragraph above.

• To the rear, the plane parallel to the vertical plane passing through the driver's ocular points

and situated at a distance of 1,75 m behind that plane.

• To the front, the plane parallel to the vertical plane passing through the driver's ocular points

and situated at a distance of 1 m in front of that plane.

If the vertical transverse plane passing through the leading edge of the vehicle bumper is less

than 1 m in front of the vertical plane passing through the driver's ocular points, the field of

vision shall be limited to that plane. In the case the field of vision described in Figure 8a and

Figure 8b can be perceived through the combination of the field of vision from a class IV wide-

angle view device and that of a class VI front-view device, the installation of a class V close-

proximity view device is not compulsory. Class V FOV and an example of the displayed view

conforming to this FOV are shown in Figure 6.

5.7 Larger FOV on the passenger side

On the passenger side only, the field of vision shall also be such that the driver can see a flat

horizontal portion of the road along the side of the vehicle which is outside the field defined in

5.6, but within the field bounded by the following vertical planes; the front of this field of vision

may be rounded off with a radius of 2 000 mm:

• In the transverse direction, the parallel plane passing at a distance of 4,5 m in front of the

plane mentioned in 5.6.

• To the rear, the plane parallel to the vertical plane passing through the driver's ocular points

and situated at a distance of 1,75 m behind that plane.

• To the front, the plane parallel to the vertical plane passing through the driver's ocular points

and situated at a distance of 3 m in front of that plane.

This field of vision may be partially provided by a front-view device (class VI). The field of vision

described may be partially provided by a wide-angle view device (class IV) or a combination of

a close-proximity view device (class V) and a front-view device (class VI).
---------------------- Page: 14 ----------------------
IEC 63033-4:2022 © IEC 2022 – 13 –

The area described in the first paragraph of this subclause may be viewed using a combination

of direct view and indirect vision devices (of classes IV, V, VI). If an indirect vision device of

class IV is used to provide a part of the field of vision described above, it shall be adjusted in a

way that it simultaneously provides the field of vision described in 5.6.

If an indirect vision device of class V is used to provide a part of the field of vision described

above, it shall be adjusted in a way that it simultaneously provides the field of vision described

in 5.6.

If an indirect vision device of class VI is used to provide a part of the field of vision described

above, it shall be adjusted in a way that it simultaneously provides the field of vision described

in 5.8.

The field of vision described in 5.6 may be viewed using a combination of a close-proximity

view device (class V) and a wide-angle view device (class IV). In such cases the close-proximity

view mirror (class V) shall provide at least 90 % of the field of vision described in 5.6 and the

class IV mirror shall be adjusted in a way that it simultaneously provides the field of vision

described in 5.5.

The above shall not apply to a vehicle where any part of a class V mirror, if fitted, or its holder,

is less than 2,4 m above the ground, regardless of its position after adjustment. The above shall

not apply to a vehicle of category M2 or M3.

A larger FOV on the passenger side and an example of the displayed view conforming to this

FOV are described in Figure 7.

5.8 Class VI FOV

The field of vision shall be such that the driver can see at least a flat horizontal portion of the

road, which is bounded by:

• A transverse vertical plane through the outermost point of the front of the vehicle;

• A transverse vertical plane 2 000 mm in front of the plane defined in the bullet point above;

• A longitudinal vertical plane parallel to the longitudinal vertical median plane going through

the outermost side of the vehicle at the driver's side; and

• A longitudinal vertical plane parallel to the longitudinal vertical median plane 2 000 mm

outside the outermost side of the vehicle opposite to the driver's side.

IEC 63033-4:2022 © IEC 2022 – 15 –

The front of this field of vision opposite to the driver's side may be rounded off with a radius of

2 000 mm. For the defined field of vision, see also 6.3. The provisions for class VI front-view

devices are compulsory for forward controlled (as defined in paragraph 12.5. of UN Regulation

No. 46) vehicles of categories N2 > 7,5 t and N3. If vehicles of these categories cannot fulfil

the requirements by using a front-view device, a vision support system shall be used. In the

case of a vision support system, this device shall be able to detect an object of 50 cm in height

and with a diameter of 30 cm within the field defined in Figure 8. A class VI FOV and an example

of the displayed view conforming to this FOV are shown in Figure 8.
