In the case of this brake control device, for example, a drive control unit is capable of executing, in a switching manner, drive control of a motor based on an operation amount and drive control of the motor based on a stored value in a storage unit. The drive control unit continues the drive control of the motor based on the operation amount until the operation amount reaches a state satisfying a predetermined convergence condition while the drive control of the motor based on the operation amount is being executed. The storage unit stores a parameter value, which is obtained in the state in which the operation amount satisfies the predetermined convergence condition, into the storage unit as the stored value.
