Improved emergency braking systems: tests show significant progress

Automatic emergency braking (AEB) technology is getting better at preventing crashes, a recent study by the American Automobile Association (AAA) shows. This progress is significant amid new federal requirements that all vehicles must be equipped with an improved version of this system by 2029.

According to the study, AEB technology is getting better at preventing crashes, according to a recent AAA study.

Comparing old and new car models with AEB

The purpose of the AAA study was to compare the performance of the AEB system on cars from different model years. The vehicles used for the tests were 2017-2018 vehicles and newer 2024 models such as the Jeep Cherokee, Nissan Rogue and Subaru Outback. The basic principle behind AEB is that the system uses forward-facing cameras and sensors to detect the likelihood of a collision and automatically applies the brakes.

The AEB system is designed to detect the likelihood of a collision and automatically apply the brakes.

Tests conducted on a closed highway have shown that the newest versions of AEB are far superior to older models in preventing crashes. At speeds of 12, 25 and 35 miles per hour, the newer cars with AEB were able to avoid a collision 100 percent of the time, while the systems on the older models worked only 51 percent of the time.

Progress in frontal collision avoidance

Despite clear improvements in system performance in preventing frontal crashes, the study found that AEB is still not effective enough to prevent other types of crashes, such as side or cornering collisions. Earlier AAA studies have confirmed that AEB systems have difficulty preventing these situations.

While there have been clear improvements in the system’s performance in preventing frontal crashes.

Greg Brannon, director of AAA’s Automotive Engineering Research Division, noted that automakers have made progress in improving AEB in recent years. However, he emphasized that there is still a lot of work to be done to make the system effective at higher speeds.

New AEB requirements

Improving AEB takes on special significance due to a new National Highway Traffic Safety Administration (NHTSA) rule that requires advanced automatic emergency braking systems to be mandatory on all passenger cars by 2029. The new version of AEB must be able to brake at higher speeds and recognize vulnerable road users, such as bicyclists and pedestrians, even at night.

Even so, automakers have expressed concerns about the rule. Earlier this year, the Alliance for Automotive Innovation, which represents the interests of most major automakers, sent a letter to NHTSA urging it to delay implementation of the new requirement, calling it “virtually impossible” given current technology.
