Abstract: A brake ECU automatically pressurizes a servo chamber of a master cylinder, and then determines whether a single system failure has occurred in the master system. When the single system failure is detected, a refresh drive is executed so that a fluid pressure chamber provided to the master cylinder is subjected to a negative pressure to cause a brake fluid to forcibly flow from a reservoir into the fluid pressure chamber via a seal member provided inside of the master cylinder and foreign matters caught by the seal member are thus washed out. The brake ECU again automatically pressurizes the servo chamber, determines whether the single system failure has been resolved, and notifies the occurrence of the single system failure when the single system failure has not been resolved.

Abstract: The braking device for a vehicle includes an operation judging portion which judges whether or not the operating amount in the increasing stage is equal to or more than a predetermined threshold amount or whether or not an increasing speed of the operating amount in the increasing stage is equal to or more than a predetermined threshold speed and a control portion which selects the first operating mode as the operating mode from a start of the increasing stage until a first timing or a second timing and selects the second operating mode as the operating mode in the increasing stage after the first timing or the second timing and at the same time maintains the drive hydraulic pressure in the increasing stage after the first timing or the second timing.

Abstract: The vehicular brake device according to the present invention is provided with a first flow passage connecting a first electromagnetic valve and a wheel cylinder, a second flow passage connecting a reservoir portion capable of storing brake fluid and the first flow passage and a second electromagnetic valve disposed in the second flow passage. A pressure differential generating portion generates a predetermined pressure differential by moving a master piston by a drive pressure generating portion after an execution of an advancement control to advance the master piston so that the stroke position of the master piston is within an advanced side area. A second electromagnetic valve control portion places the second electromagnetic valve in an open state for a period including at least a portion of the period of time in an execution period of the advancement control.
