How many stages are there in the working process of ABS?

ABS's working process can be divided into stages such as conventional braking, brake pressure maintenance, brake pressure reduction, and brake pressure increase. The functions of ABS include the following points: 1. Shorten braking time and distance: Fully utilize the effectiveness of the brakes to shorten braking time and distance. 2. Good driving stability: Effectively prevent vehicle skidding and fishtailing during emergency braking, ensuring good driving stability. 3. Good steering maneuverability: Allows steering during emergency braking, providing good steering maneuverability. 4. Reduce tire wear: Avoids severe friction between the tires and the ground, reducing tire wear.
The ABS operation process is generally divided into four stages to prevent wheel lock-up. The first stage is wheel speed monitoring, where sensors continuously scan the rotation speed of each wheel, and the computer compares this data to detect any abnormal slowing or near-stop conditions. The second stage is slip detection and decision-making; if the system detects that a wheel is about to lock, such as during hard braking or on slippery roads, it immediately initiates intervention. The third stage is pressure modulation, where the system rapidly controls brake fluid pressure via electronic valves—first reducing pressure to allow the wheel to rotate slightly, then reapplying braking pressure, repeating this cycle multiple times, similar to manual pumping of the brakes. The fourth stage is stabilization adjustment, where the system continues working until the wheel speed returns to normal, with the brake pedal vibrating slightly to indicate activity. The entire process completes within fractions of a second, preventing skidding while allowing the vehicle to steer. From my driving experience, I know ABS is crucial for reducing accidents, and maintaining proper tire pressure also enhances ABS responsiveness.
As an ordinary driver, I find the operation of ABS quite straightforward, involving just a few steps. It starts with the sensing phase, where sensors on the car monitor how the wheels are rotating. Next is the calculation phase, where the computer determines whether to activate anti-lock braking. Then comes the execution phase, where the braking system rapidly pumps pressure on and off, and you can feel a pulsing sensation when pressing the pedal. Finally, it enters the cycle phase, repeating the process until the car comes to a safe stop. This system gives me confidence in rain or snow, preventing loss of control and helping me maintain steering. The core function of ABS is to prevent wheel lock-up, reducing braking distance. I always remind myself to check the brake fluid level to ensure the system's reliability—safety comes first.
