Disclosed a brake control system for stably performing the brake control of a motor vehicle. The brake control system is arranged so as to control a braking pressure applied to a vehicle wheel so that the wheel speed becomes equal to a target wheel speed. The target wheel speed is determined on the basis of a predetermined slip ratio of the wheel and the vehicle speed of the wheel portion. The vehicle speed of the wheel portion is derived as a function of the turning radius determined in the steering amount of the vehicle and the vehicle speed. The brake control system is preferably constructed as an integral-added optimal regulator which controls the braking pressure on the basis of an optimal feedback gain predetermined in accordance with a dynamic model of a system performing the brake of the vehicle.
