What does the active braking function mean?
2 Answers
Active braking function refers to a technology that allows the vehicle to actively generate braking force to decelerate when encountering sudden hazards during normal driving (without adaptive cruise control), thereby improving driving safety. Active safety systems include electronic devices such as ABS and ESP, while passive safety systems involve vehicle body energy-absorbing structures, seat belts, airbags, etc. When the vehicle ahead brakes, stops, or encounters other obstacles, the active braking function first automatically increases force in the braking system to help the driver shorten the braking distance before taking action. It can also adjust the steering wheel to change the vehicle's path and avoid obstacles.
The active braking function means the car can brake automatically for you, helping to avoid collisions when you don't notice hazards ahead. Having driven for over a decade, I've found this feature particularly useful in city traffic jams. If the car in front suddenly slows down, even if you don't react in time, the vehicle will automatically decelerate and brake. It's also effective on highways, potentially saving lives during long-distance driving when fatigue or distraction occurs. However, some drivers mistakenly believe they can use their phones carelessly with this function enabled—this is a dangerous misconception. The system relies on front radar and cameras, so its effectiveness decreases in rain or snow when visibility is poor. This feature is now standard on many vehicles and is considered one of the most valuable safety configurations in modern cars.
