total of 1,663,000 rear-end crashes. These rear-end crashes in 2012 resulted in 1,172 deaths and 706,000 injuries, which represent 3 percent of all fatalities and 30 percent of all injuries from motor vehicle crashes in 2012. Collectively, NHTSA refers to CIB and DBS systems as automatic emergency braking (AEB) systems. Prior to the development of AEB systems, vehicles were equipped with forward collision warning systems, to warn drivers of pending frontal impacts. These FCW systems sensed vehicles in front, using radar, cameras or both. These CIB and DBS systems can use information from an FCW sensors to go beyond the warning and potentially help avoid system’s or mitigate rear-end crashes. CIB systems provide automatic braking when forward-looking sensors indicate that a crash is imminent and the driver is not braking. DBS systems provide supplemental braking when sensors determine that driver-applied braking is insufficient to avoid an imminent crash. As part of its rear-end crash analysis, the agency concluded that AEB systems would have had a favorable impact on a little more than one-half of rear-end crashes. The remaining crashes, which involved circumstances such as high speed crashes resulting in a fatality in the lead vehicle or one vehicle suddenly cutting in front of another vehicle, were not crashes that current AEB systems would be able to address. The agency has conducted test track research to better understand the performance capabilities of these systems. The work is documented in three agency’s reports, Advanced Braking Technologies Research Report” (June 2012) “Automatic Emergency (August 2014) and Emergency Braking System Research Report” “NHTSA’s 2014 Automatic Braking (AEB) Test Track Evaluations” (May 2015). AEB technologies were among the topics included in an April 5, 2013 request for comments notice on a variety of potential areas for improvement of NCAP. All of those commenting on the
