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: The vehicle brake device includes a hydraulic pressure brake device including a timing judging portion, a pressure increasing judging portion and a raising control portion for adding a raising amount of pressure selected and set from a first value relating to an allowable range, a second value relating to a response delay by filling a wheel cylinder with the operating fluid and a third value relating to a control delay relative to an electromagnetic valve which controls the hydraulic pressure braking force to the target pressure corresponding to a judgment result by the pressure increasing judging portion, when the timing judging portion judges that a time is the timing of raising.

Abstract: A vehicular braking device can shorten the time between pilot pressure input to a regulator and generation of servo pressure, and reduce product-by-product time variations for servo pressure generation. This vehicular braking device comprises: a servo pressure rising start time measurement unit that measures, in advance, a servo pressure rising start time which is the time from pilot pressure input to a first pilot chamber by opening a pressure increase valve to when a servo pressure starts to rise, and stores the servo pressure rising start time in a storage unit; a pilot pressure increase time calculation unit that calculates a pilot pressure increase time based on the servo pressure rising start time stored in advance in the storage unit; and a pre-fill control unit that increases the pilot pressure for the pilot pressure increase time by opening the pressure increase valve when brake pedal operation is detected.
