Improving Technology: A Closer Look at Automatic Emergency Braking
In a recent study conducted by AAA, findings suggest that while automatic emergency braking (AEB) technology isn’t flawless, it’s steadily advancing. The research was prompted by a federal mandate that all vehicles must feature the most sophisticated version of AEB by 2029. AAA sought to compare how newer vehicles equipped with AEB performed in contrast to older models with the technology.
Key Highlights from the Study:
- AEB utilizes forward-facing cameras and sensors to prompt the vehicle to apply brakes when a collision appears imminent.
- Newer iterations of AEB were notably more successful in preventing forward collisions than their older counterparts.
- Tests were conducted on private closed circuits using 2017-2018 models and 2024 versions of the Jeep Cherokee, Nissan Rogue, and Subaru Outback.
- The vehicles were evaluated at varying speeds (12mph, 25mph, and 35mph) to assess AEB performance.
- A dummy vehicle was positioned in the path to test AEB’s collision prevention capability.
- Results revealed that 100 percent of the 2024 vehicles successfully applied brakes before a collision, in contrast to only 51 percent of the older models.
While the recent study showcased significant enhancements in preventing forward collisions, it’s essential to note that AEB might still need refinement to address other types of crashes. Previous AAA studies identified shortcomings in preventing T-bone collisions and left turns in the path of oncoming vehicles. Despite these remaining challenges, Greg Brannon, the director of automotive engineering research at AAA, commended automakers for their progress in enhancing driver safety.
Positive Sign for the Future:
The study’s findings bode well amid the National Highway Traffic Safety Administration’s (NHTSA) newly finalized requirement for robust AEB systems in all light-duty vehicles by 2029. Although approximately 90 percent of current vehicles on the road are equipped with AEB, the upcoming rule pushes for advanced technology capable of stopping vehicles at higher speeds and detecting vulnerable road users, such as cyclists and pedestrians, even during nighttime hours.
Challenge Ahead:
Despite the advancements in AEB technology, automakers are facing hurdles in complying with the NHTSA’s mandate. The Alliance for Automotive Innovation, representing major automakers, has raised concerns regarding the feasibility of implementing the final rule, citing technological limitations and urging the agency to postpone its enforcement.
In conclusion, the evolving landscape of AEB technology underscores a pivotal shift towards enhancing road safety. As automakers navigate the challenges of implementing more advanced AEB systems, it is imperative to prioritize innovations that can mitigate a broader range of crash scenarios. By continuing to invest in research and development, the automotive industry can pave the way for a safer and more secure driving experience for all.
