Patent ID: 7926887

Claim:
A brake control system comprising: at least one wheel cylinder that receives a supply of a work fluid so as to apply a braking force to a respective vehicle wheel; a wheel cylinder pressure control system that controls a control pressure applied to the at least one wheel cylinder by controlling the supply of the work fluid to the at least one wheel cylinder; and a first abnormality determination unit that determines, during a single braking operation, whether an abnormality in the wheel cylinder pressure control system is present based on a comparison between a calculated pressure obtained in accordance with a required braking force and the control pressure after a braking request, which initiates the single braking operation, within a predetermined first abnormality determination time; and a second abnormality determination unit that determines, during the single braking operation, whether the abnormality in the wheel cylinder pressure control system is present based on a comparison between the control pressure and a reference pressure based on which a 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.
