ABSTRACT:
In an anti-lock brake control system, an actuator is controlled based on at least a slip rate determined in a slip rate calculating device and an output from a low-pass filter for filtering a wheel acceleration determined in a wheel acceleration calculating device, thereby switching-over the braking-pressure reducing, maintaining and increasing modes from one to another. The braking pressure-reduction control provided by an operation control device is terminated in response to the wheel acceleration determined in the wheel acceleration calculating device becoming equal to or larger than a preset value. Thus, it is possible to prevent an excessive pressure reduction during an anti-lock brake control on a road surface having a high coefficient of friction.
