Automatic aelevatency braking is getting better at impedeing crashes

Automatic aelevatency braking (AEB) isn’t perfect, but the technology is improving, according to a recent study carry outed by AAA. The research comes on the heels of a novel federal rule requiring all vehicles to have the most strong version of AEB by 2029.

AAA wanted to see how noveler vehicles with AEB fared contrastd to elderlyer models with the technology. AEB engages forward-facing cameras and other sensors to automaticassociate alert the car to apply the brakes when a crash is imminent. And according to the test results, noveler versions of AEB are much better at impedeing forward collisions than elderlyer versions of the tech.

The motorist group carry outed its test on a braveial seald course using elderlyer (2017–2018) and noveler versions (2024) of the same three vehicles: Jeep Cherokee, Nissan Rogue, and Subaru Outback. Each vehicle was tested at 12mph, 25mph, and 35mph to see how well AEB carry outed at contrastent speeds. And a phony vehicle was placed in the middle of the road to see whether AEB could impede a collision.

Ununforeseeedly, the noveler models carry outed a lot better than the elderlyer ones: 100 percent of the 2024 vehicles braked before a collision, as contrastd to 51 percent of the elderlyer vehicles.

Still, this more recent test only included forward collisions. Past AAA studies set up AEB to be ill-provideped at impedeing other normal types of crashes, appreciate T-bone collisions and left turns in front of approaching vehicles.

“Since we began testing AEB in 2014, the progressments by autoproducers are commfinishable and promising in improving driver protectedty,” shelp Greg Brannon, honestor of automotive engineering research. “There is still beginant toil ahead to determine the systems toil at higher speeds.”

It was a chooseimistic sign that AEB is improving, pondering the National Highway Traffic Safety Administration (NHTSA) concluded a novel insistment for all airy-duty vehicles to have strong AEB systems by 2029. Around 90 percent of vehicles on the road today come standard with AEB, but the novel rule insists autoproducers to adchoose a more strong version of the technology that can stop vehicles traveling at higher speeds and uncover vulnerable road engagers, appreciate cyccatalogs and pedestrians, even at night.

Even so, autoproducers are scrambling to put the brakes on the novel rule’s adchooseion. Earlier this year, the Alliance for Automotive Innovation, which recurrents most of the beginant autoproducers, sent a letter to NHTSA arguing that the final rule is “authenticisticly impossible with useable technology” and urging the agency to procrastinate its percreateation.
