The automatic emergency braking is improving in accident prevention.
Comparing old models with new ones.
Recent research has shown that automatic emergency braking (AEB) systems have significantly improved, although they still have some limitations. A study conducted by AAA analyzed how the latest vehicles equipped with AEB compare to older models that also have this technology. AEB uses front-facing cameras and other sensors to automatically apply the brakes when an imminent collision risk is detected. Test results indicate that newer versions of AEB are much more effective at preventing frontal collisions than their predecessors.
To carry out this research, a private circuit was used to test three vehicles from different model years: the Jeep Cherokee, Nissan Rogue, and Subaru Outback, from both 2017-2018 and 2024. The tests were conducted at speeds of 12, 25, and 35 mph with a simulated vehicle placed in the middle of the road to evaluate AEB's ability to prevent a collision. The results were clear: 100% of the 2024 vehicles stopped before colliding, compared to only 51% of the older models.
These findings reflect an improvement over previous tests conducted by AAA in 2022, where AEB showed better performance in low-speed collisions. However, it's important to note that this new assessment focused exclusively on frontal collisions. Earlier AAA studies pointed out that AEB is often not effective in preventing other types of crashes, such as T-bone collisions or when a vehicle turns left in front of an approaching one.
Greg Brannon, director of automotive engineering research, commented on the progress made since AEB testing began in 2014, highlighting that while significant advances have been achieved, there remains a need to improve these systems to operate effectively at higher speeds.
The improvement of AEB is especially relevant given that the National Highway Traffic Safety Administration (NHTSA) has established a new standard requiring all light vehicles to incorporate advanced AEB systems by 2029. Currently, approximately 90% of vehicles on the road are equipped with AEB as standard; however, the new regulation will require manufacturers to utilize more effective versions of the technology, capable of stopping vehicles at higher speeds and detecting vulnerable roadway users, such as cyclists and pedestrians, even at night.
Despite expectations, automakers are showing resistance to the adoption of this new standard. Earlier this year, the Alliance for Automotive Innovation, which represents most major manufacturers, sent a letter to the NHTSA arguing that implementing this standard is “virtually impossible with the technology available” and requesting that its implementation be delayed.
