ABSTRACT:
A brake control system includes at least one wheel cylinder that receives the work fluid to apply a braking force to a corresponding vehicle wheel, a wheel cylinder pressure control system that controls the control pressure applied to the at least one wheel cylinder by controlling the supply of the work fluid thereto, a first abnormality determination unit that determines whether an abnormality in the wheel cylinder pressure control system based on an initial response characteristic of the control pressure after a braking request within a predetermined abnormality determination time, and a second abnormality determination unit that determines whether the abnormality in the wheel cylinder pressure system is present based on a comparison between the control pressure and a reference pressure based on which the determination is made with respect to the abnormality within a predetermined second abnormality determination time that is set to expire before expiration of the first abnormality determination time.
