What does the Anti-lock Braking System (ABS) mean?
2 Answers
ABS, short for Anti-lock Braking System. Its function is to automatically control the braking force of the brake during car braking, preventing the wheels from locking up and keeping them in a state of rolling and sliding (with a slip ratio of about 20%), ensuring maximum adhesion between the wheels and the ground. The specific functions of ABS are: To fully utilize the effectiveness of the brake, shortening braking time and distance; effectively preventing vehicle sideslip and fishtailing during emergency braking, ensuring good driving stability; allowing steering during emergency braking, ensuring good steering control; avoiding severe friction between the tires and the ground, reducing tire wear. The ABS sensor is located on the inner side of the car tire and can be seen by lifting the car. There are three types of ABS sensors in total: linear wheel speed sensors, ring wheel speed sensors, and Hall-effect wheel speed sensors.
The full name of ABS is Anti-lock Braking System, which essentially prevents wheel lock-up and tire skidding during hard braking. Simply put, when you slam on the brakes, the wheels would normally stop rotating, but ABS continuously monitors each wheel's speed via sensors. If it detects a wheel about to lock, it momentarily releases brake pressure to let the wheel roll again before reapplying it. This cycle repeats dozens of times per second, maintaining slight wheel movement—allowing you to retain steering control even during panic braking. I remember testing it for the first time on snow; the car stopped firmly without skidding—super practical. Beyond that, ABS also works with other safety features like ESP to enhance handling safety. Most new cars come standard with it—truly an invisible guardian on the road.
