Based on a brand new spherical of AAA checks, computerized emergency braking programs are getting higher, however they nonetheless have room to enhance.
That enchancment is more likely to occur quickly.
What Is Automated Emergency Braking?
AEB programs use sensors to detect attainable collisions and brake to keep away from them. Typically, they gradual a automotive sufficient to forestall a collision. Once they don’t, they’ll nonetheless gradual it sufficient to reduce the severity of a crash.

These programs have been as soon as frequent solely to luxurious vehicles, however practically each automobile in the marketplace for mannequin years 2024 and 2025 advertises computerized emergency braking.
Even the least costly new vehicles, just like the under-$18,000 Mitsubishi Mirage and Nissan Versa, have AEB.
Sadly, the time period has change into one thing just like the phrase “pure” on a meals label. No authorized requirement governs what it means. AEB can fluctuate broadly from one automotive mannequin to a different.
The programs additionally change yearly as automakers enhance the {hardware} and the software program that controls it.
AAA’s Testing
AAA researchers wished to learn the way a lot AEB programs are enhancing.
AAA put two teams of vehicles via a collection of AEB checks. Each teams included vehicles of the identical make and mannequin. One group was from mannequin years 2017 and 2018, and the opposite was from mannequin yr 2024.
The brand new group outperformed the outdated.
Examined vehicles included:
• 2017 and 2024 Jeep Cherokee
• 2018 and 2024 Nissan Rogue
• 2018 and 2024 Subaru Outback
They drove every automotive towards a dummy automotive designed in order that sensors would detect it as if it have been a traditional automotive however made tender sufficient to hit safely, conducting the drives at regular charges of 12, 25, 35, 45, and 55 mph.
The Outcomes
“New mannequin automobiles (2024) have been practically twice as more likely to keep away from a collision as older mannequin automobiles,” the researchers write.
Each 2024 automotive prevented a collision at 12, 25, and 35 mph. Older fashions prevented 73% of collisions at 12 mph, 47% at 25 mph, and 33% at 35 mph.
Above 35 mph, issues acquired extra focused, as researchers solely examined automobiles that prevented collisions at decrease speeds.
“Three out of 4 automobiles evaluated have been capable of keep away from a collision at 45 mph. The take a look at velocity was elevated to 55 mph for these automobiles that prevented a collision at 45 mph. None of those remaining automobiles examined might keep away from a collision,” AAA says.
Limitations of AEB Techniques
Some automakers now promote AEB programs able to detecting bicyclists or pedestrians, however AAA didn’t take a look at these claims. Researchers examined solely ahead collision avoidance programs.
Nonetheless, an insurance coverage trade security lab, the Insurance coverage Institute for Freeway Security (IIHS), has examined these claims. In testing earlier this yr, the IIHS discovered AEB programs have been a lot much less profitable at detecting a motorbike.
Some additionally promote reverse AEB programs meant to forestall drivers from hitting a automotive when backing up. These programs struggled in AAA testing in February.
They’re Prone to Hold Enhancing
Till now, AEB has been unregulated. In April, the federal authorities introduced guidelines that can mandate AEB on all vehicles offered within the U.S. starting in 2029.
Mandating one thing everybody already does sounds redundant, however the Nationwide Freeway Site visitors Security Administration (NHTSA) has a motive for the transfer.
The brand new rule would require vehicles to move particular checks.
“The brand new normal requires all vehicles have the ability to cease and keep away from contact with a automobile in entrance of them as much as 62 miles per hour,” NHTSA says. Vehicles should additionally “detect pedestrians in each daylight and darkness. As well as, the usual requires that the system apply the brakes mechanically as much as 90 mph when a collision with a lead automobile is imminent and as much as 45 mph when a pedestrian is detected.”
Although AAA’s checks confirmed enchancment, not one of the vehicles they examined might move that take a look at.
Automakers have 5 years to enhance their AEB programs sufficient to move it.
