PROBLEM TO BE SOLVED: To provide an anti-lock brake system controller capable of realizing proper control by an ABS by predicting vehicle speed from wheel speed without relying on a slip condition of a wheel. SOLUTION: This ABS controller is provided with a rotational speed detection means for detecting the rotational speed of wheels 13FL, 13FR, 13RL, 13RR, a vehicle speed computing means 44 for computing vehicle speed based on the detected rotational speed, and a braking control means 45 for controlling braking based on the computed vehicle speed. The vehicle speed computing means 44 is provided with a rotational speed differential value calculating part 441 for calculating a differential value dω/dt of rotational speed of the wheel from a rotational speed signal, a deceleration calculating part 442 for calculating deceleration dV/dt from the calculated differential value, and a vehicle speed predicting part 443 for predicting vehicle speed based on the calculated deceleration.
