Abstract: The braking device for a vehicle includes a judging portion which judges whether the input piston and the output piston are in contact with or separated from each other and a control portion which outputs the control signal to the pilot pressure generating device so that the hydraulic pressure detected by the hydraulic pressure detecting device becomes a target value corresponding to a vehicle state, when judged that the input piston is not in contact with the output piston and outputs another control signal to the pilot pressure generating device, by which the pilot pressure becomes higher than the pilot pressure generated under a same vehicle state to a vehicle state in a case that the control signal is outputted when the judging portion judges that the input piston is not in contact with the output piston, when judged that the input piston is in contact with the output piston.

Abstract: A vehicle braking device performs a following control which makes an actual value of a physical quantity follow a first target value when the actual value of the physical quantity is a value outside a dead zone and a suppression control which suppresses a change of the actual value when the actual value is a value within the dead zone in order to control the physical quantity associated with the braking force to be the first target value. The vehicle braking device comprises a setting portion which sets a second target value which follows the first target value and which is smaller than the first target value, when the first target value is increasing and a control portion which performs a control to make the actual value approximate the second target 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: Provided is a vehicular brake apparatus capable of suppressing the occurrence of pedal shock. In this vehicular brake apparatus, a master cylinder forms a second hydraulic chamber neighboring to a first hydraulic chamber through a seal member. The seal member is arranged at a position facing the first hydraulic chamber and the second hydraulic chamber to be movable in the axial direction relative to the master cylinder. A first hydraulic pressure generating portion executes a movement restriction hydraulic pressure control such that when the operation information obtained by the operation information obtaining portion indicates that the brake operating member is not operated, the first hydraulic pressure which is higher than the second hydraulic pressure is generated in advance and consecutively, the larger a value relating to an operating amount in the operation information obtained by the operation information obtaining portion, the higher the first hydraulic pressure is generated.

Abstract: This braking control device comprises a first unit for outputting a supply pressure in accordance with operation displacement of a braking operation member, a second unit between the first unit and a wheel cylinder to increase the supply pressure and output a wheel pressure to the wheel cylinder, a displacement sensor for detecting the operation displacement, and a supply pressure sensor for detecting the supply pressure. The first unit selects either a first mode in which the operation displacement and the supply pressure are independent or a second mode in which the operation displacement and the supply pressure are linked. When the displacement sensor is normal, the first unit selects the first mode and increases the supply pressure based on the operation displacement. When the displacement sensor is not normal, the first unit selects the second mode, and the second unit increases the wheel pressure based on the supply pressure.
