ISO 22839 pdf download Intelligent transport systems — Forward vehicle collision mitigation systems — Operation, performance, and verification requirements
Scope
This International Standard specifies the concept of operation, minimum functionality, system requirements.system interfaces, and test methods for Forward Vehicle Collision Mitigation Systems (FVCMS). lt specifiesthe behaviours that are required for FVCMS, and the system test criteria necessary to verify that a givenimplementation meets the requirements of this lnternational Standard. lmplementation choices are left tosystem designers, wherever possible
FVCMS mitigate rear-end collisions. By reducing the collision energy, FVCMS reduce the degree of propertydamage, personal injury, or the likelihood of fatality. They supplement crashworthiness systems such asairbags, seatbelts and other energy-absorbing systems by reducing the impact energy that must be isolatedfrom the occupants. By autoatically activating collision mitigation braking after a Collision Warning occursFVCMS assist in slowing the vehicle when a collision is likely. While collision avoidance is not required, thislnternational Standard permits collision avoidance to be attempted by a system that conforms to FVCMSResponsibility for the safe operation of the vehicle remains with the driver.
With the exceptions of single-track vehicles and trucks with dual or triple tralers, FVCMS are for use on roadvehicles intended for public and non-public roadways. These systems are not intended for of-road use.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3,1
adaptive cruise controlACC
enhancement to conventional cruise control svstems which allows the subiect vehicle to follow a forwardvehicle 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
