Abstract: A control device including a fluid pressure control unit for controlling a pressure in a wheel cylinder by driving an electric motor of a pump on the basis of a command value; a motor target calculation unit for calculating a motor speed target value in accordance with an amount of increase in a fluid pressure target value; and a difference calculation unit for deriving a calculated value representing a difference obtained by subtracting the actual value from the target value for either the electric motor rotation speed or the pressure. The fluid pressure control unit derives the command value such that when the motor speed target value is less than the previous actual value for the electric motor rotation speed, the previous actual value is made the upper-limit of the command value, and the command value increases in proportion to the motor speed target value and to the calculated value.

Abstract: 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.
