What is the working process of ABS?

[VanAdaline]

The working process of ABS can be divided into stages such as conventional braking, brake pressure maintenance, brake pressure reduction, and brake pressure increase. Here is the relevant introduction: 1. Anti-lock Braking System: The ABS anti-lock braking system is controlled by the vehicle's microcomputer. When the vehicle brakes, it keeps the wheels rotating, thereby helping the driver control the vehicle to achieve a safe stop. 2. Braking Process: Keeping the wheels rotating during braking not only ensures the ability to control the direction of travel but also provides greater braking force in most road conditions compared to locked wheels.

I remember being truly amazed when I first learned about ABS! It's essentially an intelligent system that prevents wheels from locking up during emergency braking while still allowing the driver to steer. Here's how it works: sensors on the wheels monitor speed in real-time. If sudden deceleration indicates impending lockup, the control unit instantly signals the hydraulic module to rapidly pulse brake pressure - releasing and reapplying up to 10+ times per second. This allows intermittent wheel rotation, preventing skids. When you slam the brakes, you'll feel slight pedal pulsation and hear clicking - that's ABS activating. Originally developed for aircraft, this 1980s automotive adaptation has prevented countless accidents, becoming a cornerstone of modern safety. For maintenance, just keep wheel sensors clear of mud and change brake fluid periodically.

As an experienced driver who has driven in all kinds of road conditions, I deeply understand the role of ABS. If the wheels lock up during braking, the car can easily skid or lose control, and ABS prevents this. Its working process is quite intuitive: wheel speed sensors monitor every move, and when they detect a wheel decelerating too quickly and nearing lock-up, the computer module immediately commands the brake unit to adjust pressure, reducing braking force momentarily before restoring it, like rapidly pumping the brake pedal to keep the wheels rolling. In actual driving, when you slam on the brakes, you feel a pulsation in the pedal while still maintaining steering control. Since the widespread adoption of ABS, accidents on slippery roads have decreased by over 30%, but don't rely on it to speed excessively. I've tested it a few times on icy winter roads—with ABS engaged, the car stops steadily and safely. Just remember to check that your tire pressure isn't too low, as it can affect performance.

Having repaired cars for over a decade, the ABS mechanism is quite straightforward. The wheel speed sensor transmits data to the control computer, which triggers the solenoid valve to rapidly reduce and increase braking force once it detects a wheel is about to lock up. This alternates between sliding and rolling to prevent loss of control. During actual maintenance, it's common to encounter sensor dust accumulation triggering error lights—simply cleaning them often resolves the issue. Dirty hydraulic fluid also needs replacement to maintain pulse stability.
