Abstract: This reservoir tank is provided with a reservoir body formed in the shape of a hollow box inside which a hydraulic fluid is stored, and is connected to a vehicle master cylinder in such a way that brake fluid flows into and out of the same. The reservoir body is provided with a top plate portion formed in the shape of a plate. A flow path portion having one or a plurality of flow paths formed in a serpentine fashion and opening downward in a vertical direction is provided in a protruding manner on an inner wall surface of the top plate portion, and a slit is provided on a downstream side of the flow path.

Abstract: A control device is provided with a flow rate derivation part for deriving a pressure-holding-valve flow rate on the basis of a pressure command value and a previous pressure command value; a differential pressure derivation part for deriving a differential-pressure-valve differential pressure value so that the differential-pressure-valve differential pressure value increases with an increase in the difference obtained by subtracting the pressure-holding-valve flow rate from a pump-discharge flow rate; and a pressure-holding-valve processing part for performing an aperture derivation process to derive a command aperture so that the command aperture decreases with an increase in the difference obtained by subtracting the pressure command value from the sum of an pressure value and the differential-pressure-valve differential pressure value, and driving a holding pressure valve at the command aperture.

Abstract: This vehicle braking control device executes automatic braking control to adjust a braking torque on the basis of a vehicle target deceleration value corresponding to a distance between the vehicle and an object in front of the vehicle, and executes anti-skid control to suppress excessive wheel slip by adjusting the braking torque on the basis of a wheel speed. The braking control device calculates an actual deceleration value corresponding to the target deceleration value, and executes feedback control on the basis of the target deceleration value and the actual deceleration value such that the actual deceleration value approaches the target deceleration value. The configuration is such that a control gain of the feedback control is reduced when anti-skid control is executed. Further, the configuration may be such that execution of feedback control is prohibited when anti-skid control is executed.

Abstract: In a braking control device, a controller is configured to determine an inside and an outside of a turn by using the yaw rate, to calculate a deflection index based on a standard turning amount corresponding to a steering angle and an actual turning amount corresponding to a yaw rate, to reduce the braking torque of the rear wheel on the outside of the vehicle turn based on the deflection index when an excessive deceleration slip of the rear wheel on the inside of the vehicle turn is inhibited during an execution of anti-skid control.

Abstract: A brake device includes: a first pressurizing unit configured to increase a WC pressure by supplying brake fluid into wheel cylinders provided in wheels RL and RR; a second pressurizing unit connected to a reservoir tank via a fourth flow passage and configured to increase the WC pressure by supplying the brake fluid taken in from the reservoir tank into the wheel cylinders; and a brake control unit configured to control at least one of the first pressurizing unit and the second pressurizing unit based on a target WC pressure. The brake control unit is configured to, when the WC pressure is to be increased by operating the second pressurizing unit, execute an auxiliary brake control in which the first pressurizing unit is operated to assist the second pressurizing unit to increase the WC pressure.

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.
