Abstract: The brake device for a vehicle generates two master pressures by controlling one single servo pressure to accurately control braking force. The pressure increasing characteristic is set based on the first pressure increasing characteristic obtained from the relationship between the servo pressure and the first master pressure upon increasing the servo pressure and the second pressure increasing characteristic obtained from the servo pressure and the second master pressure. The pressure decreasing characteristic is set based on the first pressure increasing characteristic obtained from the relationship between the servo pressure and the first master pressure upon decreasing the servo pressure and the second pressure decreasing characteristic obtained from the servo pressure and the second master pressure. Thus, the total braking force of the brake device is the sum of a braking force generated by the first master pressure and a braking force generated by the second master piston.

Abstract: A hydraulic braking system includes: a master cylinder including a pressurizing piston, a rearward chamber, and a pressure chamber; and a rearward-hydraulic-pressure controller connected to the rearward chamber and including a pressure increase valve and a regulator for controlling a hydraulic pressure in an output chamber. An air detector includes: an upstream detector, including the rearward-hydraulic-pressure controller, for detecting presence or absence of air in an upstream portion based on a relationship between the hydraulic pressure in the output chamber and an open time of the pressure increase valve; and a downstream detector for detecting presence or absence of air in a downstream portion based on a relationship between a stroke of the pressurizing piston and the hydraulic pressure in the output chamber. The downstream portion includes a portion located downstream of the pressure chamber of the master cylinder.
