China is taking a bold step toward safer roads with the introduction of its first mandatory national standard for automotive driver assistance systems. Starting January 1, 2028, all light-duty vehicles must come equipped with Automatic Emergency Braking (AEB) systems as standard equipment. This move marks a significant shift from the previous optional status of AEB, ensuring that safety becomes a non-negotiable feature for every new car on Chinese roads.
What Is AEB and Why Does It Matter?
Imagine cruising down the highway when suddenly, the car in front slams on its brakes. That’s where AEB steps in. This system continuously monitors the road ahead, detecting potential collisions. If a crash seems imminent, it alerts the driver and, if necessary, automatically applies the brakes to avoid or reduce the impact. It’s like having a vigilant co-pilot who never blinks.
China’s rapid transition to electric vehicles has already seen many automakers adopt AEB as standard. By 2025, 64% of new passenger vehicles sold in China featured combined driver assistance functions, including AEB. The new standard, GB 39901—2025, formalizes this trend, requiring AEB systems to function effectively within the 10-80 km/h speed range for passenger vehicles, including sedans, SUVs, and MPVs.
Limitations and Responsibilities
While AEB is a game-changer, it’s not infallible. The Ministry of Industry and Information Technology (MIIT) has emphasized that drivers must understand its limitations. AEB is designed as an emergency aid, not a replacement for attentive driving. Proper training and awareness are crucial to maximizing its effectiveness.
Automakers are already pushing the boundaries of AEB technology. For instance, Nio Inc introduced AI-optimized AEB functionality in a July 2024 software update, enhancing its capabilities. Other manufacturers have also refined their systems, enabling activation at speeds as high as 150 km/h.
What This Means for Drivers
For everyday drivers, this new standard means greater peace of mind. Whether navigating bustling city streets or cruising on the highway, AEB adds an extra layer of protection. It’s particularly valuable in China, where dense traffic and unpredictable driving conditions can make roads hazardous.
This mandate also reflects China’s commitment to leading the global EV revolution. By prioritizing safety, the country is setting a benchmark for automotive innovation. Companies like BYD and XPeng are already integrating advanced driver assistance systems into their vehicles, blending cutting-edge technology with practicality.
A Glimpse into the Future
China’s new AEB standard is more than just a safety measure; it’s a glimpse into the future of driving. As technology evolves, we can expect even more sophisticated systems that enhance safety and convenience. For now, drivers can look forward to safer roads and a smoother driving experience, thanks to this groundbreaking regulation.
