16、 (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 com

17、mittee 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 electrot

In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was draf

22、ided, and may reduce the likelihood of collision with forward vehicles. FVCMS require information about range to forward vehicles, motion of forward vehicles, motion of the subject vehicle, driver commands and driver actions. FVCMS detect vehicles ahead, determine if detected vehicles represent a ha

23、zardous condition, and warn the driver if a hazard exists. They estimate if the driver has an adequate opportunity to respond to the hazard. If there is inadequate time available for the driver to respond, and if appropriate criteria are met, FVCMS determine that a collision is imminent. Based upon

24、this assessment, the FVCMS will activate vehicle brakes to mitigate collision severity.

26、served 1Intelligent transport systems Forward vehicle collision mitigation systems Operation, performance, and verification requirements 1 Scope This International Standard specifies the concept of operation, minimum functionality, system requirements, system interfaces, and test methods for Forward

27、 Vehicle Collision Mitigation Systems (FVCMS). It specifies the behaviours that are required for FVCMS, and the system test criteria necessary to verify that a given implementation meets the requirements of this International Standard. Implementation choices are left to system designers, wherever po

28、ssible. FVCMS mitigate rear-end collisions. By reducing the collision energy, FVCMS reduce the degree of property damage, personal injury, or the likelihood of fatality. They supplement crashworthiness systems such as airbags, seatbelts and other energy-absorbing systems by reducing the impact energ

29、y that must be isolated from the occupants. By automatically activating collision mitigation braking after a Collision Warning occurs, FVCMS assist in slowing the vehicle when a collision is likely. While collision avoidance is not required, this International Standard permits collision avoidance to

30、 be attempted by a system that conforms to FVCMS. Responsibility for the safe operation of the vehicle remains with the driver. With the exceptions of single-track vehicles and trucks with dual or triple trailers, FVCMS are for use on road vehicles intended for public and non-public roadways. These

31、systems are not intended for off-road use. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
