BRAKE CONTROL DEVICE

To enable achievement of stable braking regardless of influences by aging or the like of a brake device. There is provided a brake ECU for a vehicle with a brake device that can adjust a break force depending on fed hydraulic pressure, the vehicle including: a master pressure sensor configured to measure hydraulic pressure fed to the brake device and a G sensor and a wheel speed sensor configured to be capable of detecting acceleration of the vehicle and measure acceleration information, the brake ECU being configured to include: a pressure command value computation portion configured to determine a hydraulic pressure fed to the brake device at a time of deceleration of the vehicle on a basis of a preset coefficient and cause the determined hydraulic pressure to be fed to the brake device and a brake torque coefficient computation portion configured to learn a coefficient candidate, which is a candidate to change the coefficient, and change the coefficient to the coefficient candidate on a basis of a relationship between the hydraulic pressure and the acceleration.
