The automatic emergency braking (AEB) system has been improved. Newer (2024) model vehicles equipped with advanced driver assistance systems avoided 100% of frontal collisions when tested at speeds up to 35 mph, compared to older (2017-2018) model vehicles. avoided collisions by only 51%.
These are the highlights of a new study released Thursday by AAA Automotive Group that assessed whether AEB works as expected and whether it has improved functionality compared to older versions.
“Since we began testing AEB in 2014, automakers’ progress has been commendable and shows promise in improving driver safety,” Greg Brannon, director of automotive engineering research at AAA, said in a statement. .
Researchers say AEB technology, which uses front-facing cameras and other sensors to tell cars to automatically brake when a collision is imminent, is being installed in most new vehicles. Earlier this year, the National Highway Traffic Safety Administration (NHTSA) issued new rules requiring automakers to equip their vehicles with AEB by 2029.
The study partnered with the Automobile Club of Southern California’s Center for Automotive Research to evaluate the performance advancements of AEB systems in older model vehicles (2017-2018) compared to newer vehicles (2024) from the same manufacturer. It was conducted in a simulated closed course environment. And a model. It was rated at three common speeds: 12 mph, 25 mph, and 35 mph to see how well it performs in frontal crashes.
As a result, newer vehicles (2024) are nearly twice as likely to avoid a collision than older vehicles (2017-2018) when tested at speeds up to 35 mph, as required by current safety standards. It was shown that
(The average collision avoidance rate for the new model was 100% at all speeds and at 35 mph, 25 mph, and 12 mph. The average for the older model was 51%, 33%, 47%, and 73%, respectively. )
AAA said the results show a significant improvement over time, stating that “the latest models were able to completely avoid potential collisions even at low speeds. This improvement in AEB technology will help This is a promising development that will significantly reduce the risk of collisions.
AAA stressed that while these systems are improving and can help prevent collisions, drivers should not rely solely on technology to apply the brakes and must remain alert and engaged at all times.
Most miles driven in the United States are done at speeds above 35 miles per hour, prompting automakers to prioritize research and development of AEB systems for high-speed scenarios to ensure higher levels of safety and reliability. Automotive groups are encouraging.
When AAA engineers added test scenarios to evaluate current AEB systems at high speeds, three out of four vehicles evaluated were able to avoid crashes at speeds of 45 mph. However, when the test speed increased to 55 mph, none of the three vehicles that avoided a collision at 45 mph avoided a collision at 55 mph.
“Significant work still needs to be done to get the system running faster,” Brannon added.
