ISO 15623:2002(E) Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 15623 was prepared by Technical Committee ISO/TC 204, Transport information and control systems. Annexes A, B, C, and D form a normative part of this International Standard. ISO 2002 All rights reserved
ISO 15623:2002(E) Introduction The main system function of a Forward Vehicle Collision Warning System (FVCWS) is to warn the driver when the subject vehicle encounters the situation when a forward vehicle in the subject vehicle s trajectory becomes a potential hazard. This is done by using information about: (1) the range to forward vehicles, (2) the time to a potential collision and (3) the grade of warnings provided to the driver (see Figure 1). Based upon the information acquired, the controller identified as FVCWS warning strategy in Figure 1 produces the warning to the driver. Figure 1 Functional forward vehicle collision warning system s elements Automobile manufacturers and component suppliers throughout the world have been vigorously pursuing the development and commercialization of these FVCWS systems. Systems of this type have already been introduced onto the market in some countries. Thus the standardization efforts began in 1994 amongst interested countries. This International Standard is composed to address only the basic performance requirements and test procedures for the FVCWS type systems. This International Standard may be used as a basis by other advanced standards for systems which have more advanced features and may extend beyond this International Standard.

INTERNATIONAL STANDARD ISO 15623:2002(E) Transport information and control systems Forward vehicle collision warning systems Performance requirements and test procedures 1 Scope This International Standard specifies performance requirements and test procedures for systems capable of warning the driver of short inter-vehicle distance and closing speed which may cause a rear-end collision with other vehicles, including motor cycles, ahead of the subject vehicle while it is operating at ordinary speed. This International Standard is applicable to operations on roads with curve radii over 125 m as well as higher radius curves. 2 Normative reference The following normative document contains provisions which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent edition of the normative document indicated below. For undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain registers of currently valid International Standards. IEC 60825-1:2001, Safety of laser products Part 1: Equipment classification, requirements and user's guide (consolidated edition) 3 Terms and definitions For the purposes of this International Standard, the following terms and definitions apply. 3.1 collision warning information that the system gives to the driver indicating the need for urgent action to avoid a collision NOTE This warning is issued in the advanced stages of a dangerous situation to warn the driver of the need to perform emergency braking, lane changing or other emergency manoeuvres in order to avoid a collision. 3.2 coefficient of test target CTT coefficient representing the optical radar reflectivity of the target which is defined as the coefficient of radiated intensity, measured in front of the receiver surface, divided by the intensity of irradiation out of the transmitter NOTE See clause C.4. 3.3 forward vehicle vehicle in front of and moving in the same direction and travelling on the same roadway as the subject vehicle ISO 2002 All rights reserved 1
