ABSTRACT:
The object to be achieved by the present invention is to improve accuracy in determining whether or not it is necessary to terminate antiskid control and to reduce the frequency with which the control is terminated. The solution proposed by the present invention is to stop operation of a hydraulic pump before it is determined that the antiskid control should be terminated during the duty pressure increase operation, whereby fluid pressure in a wheel brake can be raised to a level of fluid pressure in a master cylinder before it is determined that the antiskid control should be terminated, to continue the antiskid control as long as the wheel tends to be locked and to terminate the antiskid control when the wheel does not tend to be locked.
