The ABS-ECU unit receives signals from four wheel speed sensors, detects the speed and acceleration of each wheel, and calculates the vehicle speed.
When the brake pedal is depressed, the brake fluid pressure in the brake cylinders increases and the wheel speed decreases. If the difference between the wheel speed and the vehicle speed increases and the wheel deceleration rate reaches a certain point (A), the ECU determines that the wheel may lock and reduces the brake fluid pressure by sending a signal to the electromagnetic valves (between a and b).
Then, when the wheel deceleration speed recovers and the rotation speed reaches point B, the ECU gives a pressure maintenance signal (between b and c).
When the wheel deceleration speed passes point C, the ECU determines that the possibility of wheel locking has been eliminated and sends a signal to increase the brake fluid pressure (between c and d).

Further, the brake fluid pressure is controlled by alternately increasing and maintaining the pressure (between d and e).
When the wheel deceleration rate reaches a certain value again, the cycle repeats from the beginning.
The ABS system is activated at a speed of at least 10 km/h.
The ABS system has four sensors, with the help of which it monitors the front left and right wheels independently of each other, and the rear wheels together.
Brake fluid pressure is controlled independently for all four wheels.
