What Causes the Functional Limitations of the Active Brake Assist System?
3 Answers
The possible reasons for the functional limitations of the Active Brake Assist System are as follows: 1. The radar sensor system temporarily stops operating, possibly due to interference from electromagnetic radiation emitted by nearby TV stations, radio stations, or other electromagnetic radiation sources; 2. The system is operating outside the working temperature range; 3. The vehicle's voltage is too low. Additional information: 1. Content 1: The display message will disappear automatically, and the Active Brake Assist System will resume operation. If the display message does not disappear, you can stop and restart the engine, paying attention to road and traffic conditions when stopping. 2. Content 2: The Active Brake System uses radar to measure the distance to the vehicle ahead or obstacles, and the data analysis module compares the measured distance with the warning distance and safe distance. If the distance is less than the warning distance, an alarm will be triggered.
When my car indicates that the Active Brake Assist system function is limited, my first thought is that the sensors are blocked by dust or rain. Driving on city streets, the windshield camera or bumper radar can easily get covered with mud, leaves, or bird droppings, especially in rainy or dusty conditions. The system then warns of limited functionality, preventing it from correctly identifying obstacles and automatically applying the brakes. Additionally, the software might need an update, or the vehicle system could be overloaded, leading to misjudgments. I remember during a long trip, strong sunlight reflections confused the camera, causing the system to limit the function. It’s important to clean the sensors promptly—don’t overlook that small area when washing the car—to maintain clear visibility. Keep an eye on dashboard warnings, and occasionally restarting the vehicle might help restore the system without compromising daily driving safety.
I've encountered situations where the Active Brake Assist system was limited, with common causes being nothing more than external interference or internal malfunctions. Radar and camera systems can easily get obstructed or suffer signal distortion in heavy fog, rain, or snow, making it difficult for the system to accurately judge obstacle distance and speed. Internally, loose wiring connections can lead to signal interruptions, or a blown fuse can cut off the power supply chain. There might also be software bugs requiring recalibration, which would need adjustment via diagnostic tools. Just to be safe, I recommend regularly checking the cleanliness of sensors to avoid dirt accumulation from parking under trees. Understanding the maintenance tips in the vehicle manual can help anticipate issues—don't wait until a malfunction affects safety responses to take action.
