BRAKE CONTROL DEVICE AND BRAKE SYSTEM

An object of the present invention is to provide a brake control device and a brake system capable of braking with a shortened braking response when shifting from non-braking to braking. A brake control device includes a command value calculation unit that calculates an operation command value required to make a pressing force by which a brake pad is pressed against a brake disc reach a target thrust value. The command value calculation unit includes: a clearance command calculation unit that calculates a command value required for contact between the brake pad and the brake disc ; and a thrust command calculation unit that calculates a command value required for reaching the target thrust from a state where the brake pad and the brake disc are in contact with each other. When calculating the operation command value from a state where the brake pad and the brake disc are separated, the command value calculation unit calculates the operation command value by integrating the command value calculated from the clearance command calculation unit and the command value calculated from the thrust command calculation unit
