Claim:
1. A vehicle brake device comprising: a hydraulic pressure brake device for controlling a hydraulic pressure braking force by controlling an actual pressure so that a deviation between a target pressure and the actual pressure becomes within an allowable range when the deviation is out of the allowable range and maintaining the actual pressure when the deviation is within the allowable range; and a regeneration brake device for generating a regeneration braking force, wherein a required braking force is generated by using both the regeneration braking force and the hydraulic pressure braking force, the hydraulic pressure brake device including: a timing judging portion for judging whether or not a time is a timing of raising; a pressure increasing judging portion for judging whether or not the actual pressure is out of the allowable range and at the same time is smaller than the target pressure; a selecting portion for selecting a raising amount set according to a value or values selected from a first value relating to the 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; and a raising control portion for adding the raising amount selected by the selecting portion to the target pressure when the timing judging portion judges that the time is the timing of raising.
