PROBLEM TO BE SOLVED: To perform a brake control by a hydraulic brake device certainly by correcting the drive current of a linear solenoid valve properly even in the condition mounted in a vehicle. SOLUTION: The hydraulic brake device for vehicle according to the invention is equipped with a master cylinder MC, a master piston driving means MD to drive a master piston MP using the output power hydraulic pressure of an auxiliary hydraulic pressure source AS, and a linear solenoid valve device (V1 and V2) to control at least the power hydraulic pressure supplied from the auxiliary hydraulic pressure source to the master piston driving means and also control the driving force given to the master piston. In particular when the brake pedal is out of operation, the master cylinder hydraulic pressure sensed by a pressure sensor P2 is compared with the specified reference value when current is fed to the linear solenoid valve device in the condition that the communication between the master cylinder and wheel cylinders is shut by a hydraulic control valve device HC, and on the basis of the result from comparison, the drive current of the linear solenoid valve device is corrected. |
