DRIVE MONITORING SYSTEM
Part 1: General
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.

The main task of IEC technical committees is to prepare International Standards. In
exceptional circumstances, a technical committee may propose the publication of a technical
specification when
• the required support cannot be obtained for the publication of an International Standard,
despite repeated efforts, or
• the subject is still under technical development or where, for any other reason, there is the
future but no immediate possibility of an agreement on an International Standard.
Technical specifications are subject to review within three years of publication to decide
whether they can be transformed into International Standards.
IEC TS 63033-1, which is a technical specification, has been prepared by IEC technical
committee 100: Audio, video and multimedia systems and equipment.

The text of this technical specification is based on the following documents:

Enquiry draft Report on voting

100/2819/DTS 100/2877/RVDTS
Full information on the voting for the approval of this technical specification can be found in

the report on voting indicated in the above table.

This document has been drafted in accordance with the ISO/IEC Directives, Part 2.

A list of all parts in the IEC 63033 series, published under the general title Car multimedia
systems and equipment, can be found on the IEC website.
The committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC website under "http://webstore.iec.ch" in the data
related to the specific publication. At this date, the publication will be
• transformed into an International standard,
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
A bilingual version of this publication may be issued at a later date.

IMPORTANT – The 'colour inside' logo on the cover page of this publication indicates
that it contains colours which are considered to be useful for the correct
understanding of its contents. Users should therefore print this document using a
colour printer.

INTRODUCTION
The drive monitoring system is a camera-based visual system enabling the car user to record

and view in real time the surrounding visual image of their vehicle from anywhere within a

360° surround view perspective. The purpose of this document is to specify the model for

generating the desired surrounding visual image of the drive monitoring system. Typically, the

drive monitoring system is defined by the audio-visual monitoring system requirements of the

car multimedia system and equipment.

To ensure the correct positioning of the car in relation to its surroundings, the rear-view

monitor for parking assistance, the blind spot monitor for displaying views of the blind spots,

and the bird’s-eye view monitor are used. Each drive monitoring system provides a different
viewpoint to the car's driver. It’s a heavy burden for a car driver to switch between these
systems and quickly recognize the multiple fields of view. In addition, the fields of view are
limited to these camera systems which cannot freely change the eye point depending on the
driving situation. As a result, the usage cases for these types of systems are limited to
singular functions such as parking assistance. Furthermore, on commercial vehicles such as
trucks, buses and other special vehicles, ranging from construction to agricultural machinery,
the usage cases for these systems is even more limited. In these vehicle types, there might
exist situations in which no one is available to assist the driver in properly ensuring the car's
correct and safe position.
To resolve these problems, the drive monitoring system provides the driver with the optimal
surround view image as constructed by the model explained in this document. It provides the
optimal viewpoint of the vehicle and its surroundings to the driver for ensuring the car’s good
positioning in various driving situations (parking, turning, high traffic situations, etc.). This is
not only true for passenger cars, but good positioning can also be quickly ensured for
commercial vehicles and other special vehicles as well.
Part 1 specifies the model for generating the surrounding visual image of the drive monitoring
system. Part 2 specifies the information sets that are provided by the drive monitoring system,
which include recording methods for that information and the actual visual images. Part 3
specifies the measurement methods of surrounding visual images for the drive monitoring
system.
