AAA‘s latest research highlights advancements in Automatic Emergency Braking (AEB) systems, with new (2024) model vehicles successfully avoiding collisions at speeds up to 35 mph. The research, comparing older (2017-2018) and newer models, found that newer vehicles achieved 100% collision avoidance at lower speeds, while older models only succeeded 51% of the time. This progress demonstrates the evolving capabilities of AEB technology and its significant role in enhancing road safety.
Key Highlights:
- New AEB systems avoided 100% of collisions at speeds up to 35 mph, compared to a 51% success rate for older models.
- NHTSA mandates AEB in all vehicles by 2029, pushing for safer automotive standards.
- AAA research shows continued progress in AEB systems but underscores the need for enhancements at higher speeds.
Advancements in AEB Technology
Automatic Emergency Braking (AEB) uses forward-facing cameras and sensors to detect imminent collisions and automatically apply brakes. Most new vehicles are equipped with this feature, and a new Federal Motor Vehicle Safety Standard (FMVSS) issued by the National Highway Traffic Safety Administration (NHTSA) mandates all vehicles to include AEB by 2029. AAA’s research found that new model vehicles avoided forward collisions 100% of the time at speeds up to 35 mph, a substantial improvement compared to older models.
Greg Brannon, AAA’s Director of Automotive Engineering Research, stated, “Since we began testing AEB in 2014, the advancements by automakers are commendable and promising in improving driver safety. There is still significant work ahead to ensure the systems work at higher speeds.”
Research Findings
AAA, in collaboration with the Automobile Club of Southern California’s Automotive Research Center, conducted research comparing older (2017-2018) and newer (2024) model vehicles’ AEB performance in a closed-course environment. Vehicles of the same make and model were tested at speeds of 12 mph, 25 mph, and 35 mph, with new models consistently outperforming their older counterparts.
The newer vehicles showed nearly double the success rate in avoiding collisions compared to older models when tested at speeds up to 35 mph. However, the research also evaluated AEB effectiveness at higher speeds. While three out of four vehicles avoided collisions at 45 mph, none succeeded at 55 mph, revealing limitations in current AEB technology.
Recommendations for Industry
AAA emphasized the need for ongoing development of AEB systems capable of handling higher-speed scenarios, aligning with the NHTSA ruling that requires vehicles to avoid collisions at speeds up to 62 mph by 2029. Automakers are encouraged to enhance Forward Collision Warning (FCW) alerts, allowing drivers more reaction time, and to continue investing in sensor technologies, braking algorithms, and comprehensive testing to improve safety.
Driver Advice
- Never rely solely on technology to apply brakes; AEB is an assistive feature, not a replacement for driver attention.
- Stay aware of system limitations and remain engaged, even with advanced safety features.
- Avoid risky behaviors like speeding, distracted driving, and driving under the influence to reduce collision risks.
A Path Forward for Safer Roads
The progress in AEB technology underscores the positive trend toward improved vehicle safety, yet challenges remain, particularly at higher speeds. As AEB systems advance, the collaboration between technology and attentive driving will be crucial to maximizing their safety benefits. AAA will continue monitoring these advancements to ensure future safety improvements align with evolving standards.
