Abstract
Vehicle anti-lock brake control apparatus having wheel speed sensor for detecting actual speed of a vehicle wheel, solenoid-operated valve for regulating the wheel braking pressure, and controller for controlling the valve, on the basis of the detected actual speed, and vehicle ground-speed detected by ground-speed sensor. The controller controls the valve at a controlled duty cycle, which is determined on the basis of at least a wheel speed error and a time derivative of this error. The error is obtained as a deviation of the detected actual wheel speed from a target wheel speed obtained on the basis of the detected vehicle ground-speed.
