Improving Effectiveness of Automatic Emergency Braking

Improved Automatic Emergency Braking Technology

Automatic emergency braking (AEB) continues to evolve, with recent research from AAA indicating significant advancements in the technology. This comes in the wake of a federal mandate requiring all vehicles to incorporate the most advanced AEB by 2029.

AAA Study on AEB Performance

AAA’s investigation aimed to compare the efficacy of newer vehicles equipped with AEB against older models. Utilizing forward-facing cameras and sensors, AEB triggers automatic braking when a collision is imminent. The results highlight that newer AEB versions outperform their predecessors in preventing forward collisions.

Test Results

In a controlled assessment, AAA evaluated older (2017–2018) and newer (2024) versions of Jeep Cherokee, Nissan Rogue, and Subaru Outback. Tests conducted at 12mph, 25mph, and 35mph revealed the enhanced performance of newer AEB in various speed scenarios. A dummy vehicle was used to simulate a potential collision.

100 percent of new vehicles braked before a collision

The newer vehicle models demonstrated superior performance, with all 2024 vehicles successfully initiating braking before a collision, compared to only 51 percent of older models.

Limitations of AEB

While AEB proves effective in preventing forward collisions, previous studies by AAA have identified shortcomings in addressing other common crash scenarios like T-bone collisions and left turns in front of oncoming vehicles.

Future of AEB

Greg Brannon, director of automotive engineering research at AAA, commended the progress in AEB technology since testing began in 2014. Despite advancements, he notes the need for further enhancements to ensure optimal performance at higher speeds.

NHTSA’s mandate for robust AEB systems in all light-duty vehicles by 2029 underscores the industry’s commitment to improving road safety. While most vehicles currently feature AEB as standard, the new rule emphasizes the need for advanced technology capable of halting vehicles at higher speeds and detecting vulnerable road users, even in low-light conditions.

Challenges Ahead

Despite the progress, automakers are voicing concerns over the feasibility of implementing NHTSA’s final rule by 2029. The Alliance for Automotive Innovation, representing major automakers, has raised apprehensions about the technological challenges and urged a delay in enforcement.

FAQs

Q: What is Automatic Emergency Braking (AEB)?

A: AEB is a safety technology that uses sensors and cameras to detect imminent collisions and automatically apply the brakes to prevent accidents.

Q: Why is AEB important for vehicle safety?

A: AEB helps reduce the risk of collisions by initiating automatic braking when a potential crash is detected, enhancing overall road safety.
