Federal Motor Vehicle Safety Standards: Vehicle-to-Vehicle (V2V) Communications

摘要

This document initiates rulemaking that would propose to create a new Federal Motor Vehicle Safety Standard (FMVSS), FMVSS No. 150, to require vehicle-to-vehicle (V2V) communication capability for light vehicles (passenger cars and light truck vehicles (LTVs)) and to create minimum performance requirements for V2V devices and messages. The agency believes that requiring V2V communication capability in new light vehicles would facilitate the development and introduction of a number of advanced vehicle safety applications. Some crash warning V2V applications, like Intersection Movement Assist (IMA) and Left Turn Assist (LTA), rely on V2V-based messages to obtain information to detect and then warn drivers of possible safety risks in situations where other technologies have less capability. Both of those applications address intersection crashes, which are among the most deadly crashes that U.S. drivers currently face. NHTSA believes that V2V capability will not develop absent regulation, because there would not be any immediate safety benefits for consumers who are early adopters of V2V. V2V begins to provide safety benefits only if a significant number of vehicles in the fleet are e
