Abstract
A brake control apparatus includes a main brake controller configured to control a brake fluid pressure supplied to main brakes provided to a vehicle's four wheels according to a proceeding vehicle's traveling conditions to automatically stop the vehicle using a braking operation of the main brakes and maintain the stop condition and an auxiliary brake controller configured to control parking auxiliary brakes provided to right and left front wheels or right and left rear wheels of the vehicle to perform a braking operation so as to maintain the stop condition of the vehicle. When the auxiliary brakes perform the braking operation while the brake fluid pressure is being supplied to the main brakes to stop the vehicle, the main brake controller rapidly reduces the brake fluid pressure to a predetermined fluid pressure value and then gradually reduces the brake fluid pressure before the main brakes are released.
