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.

Claim (Index 1):
A vehicular brake apparatus comprising:\n a hydraulic pressure output portion which includes a master cylinder forming a first hydraulic pressure chamber and a piston which is driven by a force corresponding to a first hydraulic pressure which is a hydraulic pressure in the first hydraulic pressure chamber to be slidably movable in the master cylinder, thereby to output an output hydraulic pressure which is a hydraulic pressure corresponding to a stroke of the piston; an operation information obtaining portion which obtains an operation information relating to an operation of a brake operating member; and a first hydraulic pressure generating portion which generates the first hydraulic pressure in response to the operation information obtained by the operation information obtaining portion, wherein a braking force is generated at a wheel of a vehicle based on the output hydraulic pressure, wherein the master cylinder forms a second hydraulic pressure chamber neighboring to the first hydraulic pressure chamber through a sealing member; the sealing member is arranged at a position facing the first hydraulic pressure chamber and the second hydraulic pressure chamber to be movable in an axial direction relative to the master cylinder; the second hydraulic pressure chamber is configured such that a second hydraulic pressure which is a hydraulic pressure in the second hydraulic pressure chamber is mechanically increased or decreased in response to the operation of the brake operating member and at the same time a force corresponding to the second hydraulic pressure acts on the brake operating member; and the 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.
