Brake control system and brake control method

A brake control system includes a target braking force calculator to calculate a target braking force for causing a vehicle to decelerate in accordance with a braking instruction containing a normal braking instruction or emergency braking instruction, and a target pressure calculator to calculate a target pressure, indicating a target value of pressure of fluid to be fed to a mechanical brake device for activating the mechanical brake device, based on the target braking force. The brake control system further includes a compensation controller to execute control for compensating for the gap between the actual braking force and the target braking force when the braking instruction contains an emergency braking instruction, and an outputter to compress fluid fed from a fluid source in accordance with the target pressure and feed the compressed fluid to the mechanical brake device.
