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.

Abstract: A vehicle brake device is provided with a regulator for generating a servo pressure acting on a master piston in a master cylinder, based on a pilot pressure. The regulator is provided with a brake fluid absorbing section communicating with a first pilot chamber for absorbing the brake fluid as the pilot pressure in the first pilot chamber in the quantity depending on the fluid pressure in the first pilot chamber. The brake fluid absorbing section comprises a piston receiving portion formed in a second piston and opening to the first pilot chamber, a pressure receiving piston slidably received in the piston receiving portion and making the first pilot chamber variable in capacity, and an urging member urging the pressure receiving piston toward the first pilot chamber side.

Abstract: A control apparatus for a vehicle includes processing circuitry. The processing circuitry calculates a target torque such that the greater the amount of brake operation is, the smaller the target torque becomes. The processing circuitry controls the drive motor such that the creep torque is smaller when brake operation is being performed by the driver than when the brake operation is not being performed by the driver. The control circuitry controls the brake device such that, when the brake operation is being performed by the driver, the brake torque approaches a target brake torque. The processing circuitry sets a decrease gradient of the creep torque to be smaller than a decrease gradient of the target torque when the brake operation amount is increased under a condition in which the creep torque is being output by the drive motor.
