Abstract: A braking control device includes a “master cylinder CM capable of pressure feeding brake fluid BF in conjunction with the movement of a brake operating member BP of a vehicle”, an “electrically driven fluid unit HU”, “front wheel and rear wheel cylinders CWf, CWr that are provided on the front wheel and rear wheel WHf, WHr of the vehicle and are pressurized by either one of the master cylinder CM and the fluid unit HU”, and a “controller ECU that controls the fluid unit HU”. The controller ECU determines whether or not external leakage of a brake fluid BF has occurred in the braking control device, and when the external leakage has occurred, pressurizes the front wheel cylinder CWf by the master cylinder CM, and pressurizes the rear wheel cylinder CWr by the fluid unit HU.

Abstract: A braking control device is applied to, for example, a vehicle in which a regenerative braking force is generated on a front wheel by a regenerative generator provided on the front wheel. The braking control device includes an actuator configured to individually generate a front wheel friction braking force on the front wheel and a rear wheel friction braking force Fmr on a rear wheel of the vehicle; and a braking controller configured to control the actuator. In the braking control device, the braking controller is configured to regulate the front and rear wheel friction braking forces based on a normative regenerative force corresponding to a rotation speed equivalent value equivalent to a rotation speed of the regenerative generator.

Abstract: A vehicle braking device includes: a first hydraulic pressure output unit that is connected to a master chamber through a first liquid passage and outputs hydraulic pressure to first wheel cylinders based on a hydraulic pressure of the first liquid passage; a hydraulic pressure generating unit that generates hydraulic pressure independently of a master cylinder; a second hydraulic pressure output unit that is connected to the hydraulic pressure generating unit through a second liquid passage and outputs hydraulic pressure to second wheel cylinders based on a hydraulic pressure of the second liquid passage; a normally closed communication control valve that is provided in a communication passage connecting the first liquid passage and the second liquid passage and opens and closes the communication passage; and a normally open master cut valve in the first liquid passage on the master cylinder side relative to a connection portion with the communication passage.
