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.
