Abstract: A braking control device includes a first control unit configured to execute first control for reducing a target braking force, which is either a front-wheel braking force to be applied to front wheels of a vehicle or a rear-wheel braking force to be applied to rear wheels during increasing of deceleration of the vehicle, in a case that a behavior of the vehicle is unstable as the target braking force is increased; and a second control unit configured to execute second control for reducing a rate of increase in the target braking force and increasing a rate of increase in the front-wheel braking force or the rear-wheel braking force, which is not the target braking force, prior to execution of the first control.

Abstract: A braking control device includes an actuator, a controller, a steering angle sensor, and a yaw rate sensor. The controller calculates a reference turning amount, an actual turning amount, an understeer index, sets to a non-adjustment region in which the increase slope is not decreased when the understeer index is smaller than or equal to a first threshold value, sets to an adjustment region in which the increase slope is decreased when the understeer index is greater than or equal to a second threshold value greater than the first threshold value, and sets to a transition region in which the increase slope is decreased when the understeer index is transitioned from the non-adjustment region and the increase slope is not decreased when the understeer index is transitioned from the adjustment region when the understeer index is greater than the first threshold value and smaller than the second threshold value.

Abstract: A braking control device comprises: an operational displacement sensor detecting operational displacement of a braking member; a first hydraulic pressure unit that reads operational displacement as a first displacement processing value via a first displacement signal line and adjusts braking hydraulic pressure based on the first displacement processing value; a second hydraulic pressure unit that reads operational displacement as a second displacement processing value via a second displacement signal line and adjusts braking hydraulic pressure based on the second displacement processing value; and a communication bus transmitting signals between the first and second hydraulic pressure units. The first hydraulic pressure unit acquires the second displacement processing value via the communication bus and determines suitability/unsuitability of the first displacement processing value. When the first displacement processing value is suitable (unsuitable), the first hydraulic pressure unit adjusts the braking hydraulic pressure on the basis of the first (second) displacement processing value.

Abstract: A vehicle braking control device is capable of further raising the speed at which vehicle vehicle-body deceleration increases when automatic braking processing implementation begins. Provided as a braking control device is a control device comprising: an acquisition unit that acquires an indicator; and a braking control unit that starts the implementation of automatic braking processing if a determination is made, on the basis of the indicator, that an automatic braking condition has been established. In the automatic braking process, the braking control unit restricts the supply of brake fluid to wheel cylinders corresponding to the rear wheels, and supplies brake fluid to wheel cylinders corresponding to the front wheels to increase the pressure of the wheel cylinders, thereby increasing the braking power for the front wheels and also giving the rear wheels braking power corresponding to the driving amount of a motor for parking.

Abstract: The vehicular brake device includes a determination unit, a ratio setting unit, and the control unit. The determination unit determines the operating condition of a vehicular brake device. The ratio setting unit sets, on the basis of the result of determination by the determination unit, a first ratio which is the ratio of a wheel pressure generated by a piston drive unit to a target wheel pressure, and a second ratio which is the ratio of a wheel pressure generated by a hydraulic pressure adjusting unit to the target wheel pressure. The control unit controls the piston drive unit and the hydraulic pressure adjusting unit on the basis of the first ratio and the second ratio.
