What to Do When the Automatic Emergency Braking Function is Limited?
2 Answers
When the automatic emergency braking function is limited, it should be checked and repaired in time to avoid accidents. The following is an introduction to the knowledge of the automatic emergency braking function: 1. Introduction: The active brake assist system is mainly composed of three modules, including the control module, distance measurement module, and brake module. It uses radar, ultrasonic, camera and other equipment to detect the road ahead. After detecting a collision risk, the vehicle computer will automatically apply emergency braking. 2. Reasons for limitation: The functional range of the active brake assist system may also be limited due to heavy rain or snow causing functional impairment. The radar sensor system failure may be due to dirty sensors. If the front radar sensor system is dirty, the active blind spot assist system will attempt to correct the driving route with braking and will also sound a warning tone.
The automatic emergency braking system has been limited, and as a veteran driver with over 20 years of experience, I've encountered this a few times. The first step is definitely to check if the front camera and radar are covered by mud, snow, or bugs; after parking, gently wipe them clean, and sometimes the false alarm disappears. Try restarting the car—turn off the engine, wait a few minutes, and then start it again, as this might reset the system. If that doesn’t work, pay attention to the dashboard warning lights and don’t ignore small signals. When the function is limited, you need to be extra cautious: maintain a greater following distance, drive slower, and never rely on assisted braking to save your life. Visit a 4S shop as soon as possible for a check-up—it might be a software update issue, sensor calibration problem, or environmental factors like rain or fog affecting accuracy. Preventive maintenance is crucial: don’t forget to clean the sensor areas near the windshield when washing the car, and schedule regular system checks to save on hefty repair costs. Safe driving habits are key—over-reliance on technology can easily lead to trouble.
