Abstract: A hydraulic pressure braking force generation device is provided with a first control unit for performing control for inhibiting excessive responses in which the input pressure is controlled such that the output pressure is within a first region set using a braking target oil pressure as a reference, a second control unit for performing control for responsiveness in which the increase speed or decrease speed of the input pressure is increased so as to be larger than that in the control for inhibiting excessive responses, to cancel response delay and a switching unit which, on the basis of the state of the braking target oil pressure, switches between the control for inhibiting excessive responses performed by the first control unit and the control for responsiveness performed by the second control unit.

Abstract: Vibrations of a hydraulic pressure in an upstream portion due to operations of a slip control device during anti-lock control are transmitted to a control pressure chamber via a pressurizing piston of a master cylinder and a control piston of a regulator. During anti-lock control, in contrast, a pressure-increase linear valve and a pressure-reduction linear valve are opened, allowing change in volume of the control pressure chamber, resulting in reduction in stiffness. This reduction suppresses vibrations of a hydraulic pressure in the control pressure chamber, resulting in suppression of vibrations of a hydraulic pressure in a front pressure chamber. As a result, it is possible to reduce the lowering in control accuracy for a hydraulic pressure in a brake cylinder in anti-lock control using the hydraulic pressure in the front pressure chamber, which can well avoid a long braking distance.

Abstract: A valve control device includes a correction unit that corrects hysteresis in output of a control valve according to an increasing/reducing direction of a control output value; a detection unit configured to detect an actual output value to the control valve corresponding to the control output value; and a forbidding unit configured to forbid correction by the correction unit, until a difference between the control output value and the actual output value becomes within a predetermined range, after the increasing/reducing direction of the control output value is switched.

Abstract: A brake device for controlling an actual pressure of an output hydraulic pressure outputted from a pressure adjusting device and applying a braking force to a wheel of a vehicle based on the actual pressure of the output hydraulic pressure. The brake device includes an actual pressure judging portion configured to judge whether or not the actual pressure of the output hydraulic pressure is the pressure that is within the range of the dead zone and a adjusting portion configured to execute a target pressure adjustment for adjusting a target pressure of the output hydraulic pressure to approximate a side of the actual pressure of the output hydraulic pressure.

Abstract: A vehicular brake device that implements ESC/TRC control suppresses hydraulic pressure variations produced during open/close control of a brake actuator holding valve or depressurizing valve. While a brake operating member is not operated and a wheel cylinder pressure supplying control is executed to supply target wheel cylinder pressure to respective wheel cylinders, the target servo pressure is set to a first predetermined target servo pressure smaller than a maximum output pressure of the servo pressure generating device. When wheel cylinder pressure supplying control starts, the target servo pressure is set as the target wheel cylinder maximum value when a firstly occurred rising inclination of the target wheel cylinder maximum value is equal to or more than a minimum increment of an output of the servo pressure generating device per unit time and at the same time when the target wheel cylinder pressure is below the first determined target servo pressure.

Abstract: Taking a stroke within a period from when an operation of a brake operating member is started to when a predetermined stroke operation is performed as an ineffective stroke in which the master cylinder pressure is not generated, a control means controls an amount of differential pressure formed by a differential control valve such that a hydraulic braking force that corresponds to a stroke of the brake operating member is generated during the ineffective stroke, and even after the stroke of the brake operating member exceeds the ineffective stroke, increases the wheel cylinder pressure by performing raising of the amount of differential pressure formed by the differential pressure control valve by a predetermined raising amount with respect to the amount of differential pressure during the ineffective stroke.

Abstract: In a vehicular brake device, while a brake operating member is not operated and a wheel cylinder pressure supplying control is executed to supply the target wheel cylinder pressure to the respective wheel cylinders individually, the vehicle control device sets the target servo pressure to a first predetermined target servo pressure which is a value smaller than a maximum output pressure of the servo pressure generating device. When the execution of the wheel cylinder pressure supplying control starts, the vehicle control device sets the target servo pressure to be the target wheel cylinder maximum value when a firstly occurred rising inclination of the target wheel cylinder maximum value is equal to or more than a minimum increment of an output of the servo pressure generating device per unit time and at the same time when the target wheel cylinder pressure is smaller than the first determined target servo pressure.
