USA - Notice of Proposed Rulemaking - Federal Motor Vehicle Safety Standards: Automatic Emergency Braking Systems for Light Vehicle

​This Notice of proposed rulemaking (NPRM) proposes to adopt a new Federal Motor Vehicle Safety Standard to require automatic emergency braking (AEB), including pedestrian AEB (PAEB), systems on light vehicles. An AEB system uses various sensor technologies and sub-systems that work together to detect when the vehicle is in a crash imminent situation, to automatically apply the vehicle brakes if the driver has not done so, or to apply more braking force to supplement the driver's braking. The AEB system proposed in this NPRM would detect and react to an imminent crash with a lead  vehicle or pedestrian. This NPRM promotes National Highway Traffic Safety Administration's (NHTSA) goal to equip  vehicles with AEB and PAEB, and advances DOT's January 2022 National Roadway Safety Strategy that identified requiring AEB, including PAEB technologies, on new passenger vehicles as a key Departmental action to enable safer vehicles. This NPRM also responds to a mandate under the Bipartisan Infrastructure Law directing the Department to promulgate a rule to require that all passenger vehicles be equipped with an AEB system.​
