ISO-22839:2013 pdf download.Intelligent transport systems一Forward vehicle collision mitigation systems一Operation, performance, and verification requirements.
ISO-22839 specifies the concept of operation, minimum functionality, system requirements, system interfaces, and test methods for Forward 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 possible.
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 energy 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 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 systems are not intended for oft-road use.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
adaptive cruise control
ACC
enhancement to conventional cruise control systems which allows the subject vehicle to follow a forward vehicle at an appropriate distance by controlling the engine and/or power train and optionally the brake
3.2
adjacent lane
lane of travel sharing one lane boundary with the lane in which the subject vehicle is traveling, and having the same direction of travel as the subject vehicle
3.3
articulated vehicle
any road vehicle with more than two wheels that is configured for normal road use with at least two segments, and for which each adjacent pair of segments is connected by a joint, and for which propulsion is provided by at least one segment
3.4
brakes
components which generate the forces opposing the movement of the vehicle
EXAMPLES Friction brakes (when the forces are generated by friction between two parts of the vehicle moving relative to one another); electrical brakes (when the forces are generated by electra-magnetic action between two parts of the vehicle moving relatively but not in contact with one another); fluid brakes (when the forces are generated by the action of a fluid situated between two parts of the vehicle moving relatively to one another); or engine brakes (when the forces are derived from an artificial increase in the braking action, transmitted to the wheels, of the engine).
