How does the ABS pump work?

ABS working principle: It relies on highly sensitive wheel speed sensors installed on each wheel and vehicle speed sensors on the body, controlled by a computer. More information about ABS is as follows: 1. ABS can be divided into two types: mechanical and electronic. 2. Electronic ABS consists of wheel speed sensors, wiring harness, computer, ABS hydraulic pump, indicator lights, and other components. 3. Mechanical ABS only uses the physical characteristics of components to operate mechanically, while electronic ABS uses a computer to analyze and calculate various data to derive results. 4. The main function of ABS is to improve the overall braking performance of the vehicle, enhance driving safety, prevent wheel lock-up during braking, thereby ensuring that the driver can still control the direction during braking and preventing rear axle skidding.
After driving for so many years, I've got the ABS pump's tricks down pat. It's like a clever traffic cop managing the braking system. Sensors on all four wheels monitor the rotation speed, and if any wheel is about to lock up and skid, the sensor immediately reports it to the control brain, the ECU. That's when the ABS pump starts showing off: its solenoid valves and pistons work together to rapidly increase and decrease pressure, allowing the brake calipers to pulse up to a dozen times per second, right at the threshold of tire lock-up. The most impressive part is that it lets you steer even during hard braking—once, it saved me by helping me avoid an obstacle on a snowy day. You don't notice it during normal driving, but it's a lifesaver in critical moments!
