Method for controlling brake systems

A brake system control method is provided which makes it possible to carry out ABS control depending on actual road surface conditions in carrying out ABS control while automatic braking is being activated. The control mode of an ABS controller (3) carried out while automatic braking is being activated is set at select-low control for both front (2FL, 2FR) and rear (2RL, 2RR) wheels so that braking forces will act such that slips of the right (2FR, 2RR) and left (2FL, 2RL) wheels produced due to actual road surface conditions will be the same. Thus, it is possible to prevent yawing and prevent the steering wheel from getting out of control and to ensure maximum braking force according to the actual road surface conditions.
