What are the reasons for the restricted automatic emergency braking function in BYD vehicles?

[DeJoel]

The reasons for the restricted automatic emergency braking function in BYD vehicles are as follows: 1. Dirt on the multifunctional video controller camera area of the front windshield; 2. Malfunction of the multifunctional video controller itself; 3. Failure of the mid-range detection radar; 4. Wiring faults; 5. Other interference issues. Additional information: The AEB (Autonomous Emergency Braking) system is designed to enhance driving safety. It actively applies the brakes (though it may not always bring the vehicle to a complete stop) when the vehicle encounters sudden hazards or when the distance to the preceding vehicle or pedestrian is less than the safe distance, thereby avoiding or reducing the occurrence of rear-end collisions and other accidents.

I've driven BYD for many years and encountered this issue too. When the automatic emergency braking is limited, I've found the most common cause is the front camera or radar being covered by dirt—like bugs, mud, or snow—which prevents the system from detecting vehicles ahead. Software glitches can also act up, such as outdated updates or system bugs, leading to false alarms. Unstable battery voltage or aging sensors themselves can be factors too. Before driving, I've made it a habit to clean the front sensor area with a soft cloth to avoid dust buildup. If the system becomes limited, it's best not to rush onto highways; instead, drive slowly to a 4S shop for a thorough check—after all, this concerns emergency braking safety, so don't take it lightly. During regular maintenance, always have this system inspected to avoid surprises on the road.

I've been studying cars, and BYD's function limitations are often caused by sensors. The camera or radar may be obstructed, such as when water vapor blurs the view in rainy or foggy conditions, or when debris enters the front bumper area. On the software side, it could be due to outdated updates or background conflicts, and sometimes a system restart can fix the issue. Hardware failures like loose sensor connections or short circuits can also limit functionality. While driving, pay attention to whether the dashboard warning lights are on. If they start flashing, stop and check immediately. Developing a habit of regular cleaning can reduce problems—safety is more important than anything else.

Automatic emergency braking limitations may stem from several simple causes. Dirty sensors or obstruction by foreign objects rank as the top issue, particularly after long trips when dust easily accumulates. Software glitches or outdated systems can also generate false fault alerts. Hardware problems such as damaged radar modules or aging wiring can similarly trigger limitations. Try cleaning the sensors immediately—if the issue persists, promptly visit a professional repair shop to ensure road safety.
