Abstract: The braking control device decelerates a vehicle by automatically increasing a brake fluid pressure as a hydraulic pressure in a wheel cylinder at the time when a braking operation member is not operated, and includes: a pressure regulating valve provided to a connection path for connecting a master cylinder and the wheel cylinder and regulating a differential pressure between a master cylinder hydraulic pressure as a hydraulic pressure in the master cylinder and the brake fluid pressure; a fluid pump driven by an electric motor and discharging a brake fluid into the connection path between the pressure regulating valve and the wheel cylinder; and a controller controlling the pressure regulating valve and the electric motor. When the brake fluid pressure no longer has to be increased, the controller closes the pressure regulating valve and stops driving the electric motor.

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.

Abstract: This braking control device comprises: a first unit that outputs a supply pressure in accordance with the amount of operation of a braking operation member; a second unit that is provided between the first unit and a wheel cylinder, and adjusts the supply pressure to output a wheel pressure to the wheel cylinder; a communication bus for communicating signals between the first unit and the second unit; an operation amount sensor that detects the operation amount; and a supply pressure sensor that detects the supply pressure. In the braking control device, when there is an abnormality in signal communication, the second unit calculates a target pressure on the basis of the operation amount and adjusts the wheel pressure on the basis of the difference between the target pressure and the supply pressure.

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.
