Abstract: A brake control device adjusts a front wheel braking hydraulic pressure of front wheel cylinders provided on front wheels of a vehicle and a rear wheel braking hydraulic pressure of rear wheel cylinders provided on rear wheels of the vehicle. The brake control device includes a hydraulic pressure generating unit configured to adjust a hydraulic pressure generated by an electric motor to an adjusted hydraulic pressure and apply the adjusted hydraulic pressure as the rear wheel braking hydraulic pressure and a hydraulic pressure correcting unit configured to adjust to decrease the adjusted hydraulic pressure to be a corrected hydraulic pressure, and apply the corrected hydraulic pressure as the front wheel braking hydraulic pressure.

Abstract: A vehicle hydraulic brake system of the brake-by-wire type includes input piston and a master piston configured to be actuated under hydraulic pressure introduced into a second fluid chamber and mounted in the housing so as to be movable relative to each other through a partition wall and a first fluid chamber. The piston defines therein a communication passage which extends from a fourth fluid chamber to the first fluid chamber and in which a check valve is mounted. When the piston is advanced under hydraulic pressure introduced into the second fluid chamber, the volume of the fourth fluid chamber decreases, while the volume of the first fluid chamber increases. This allows brake fluid in the fourth fluid chamber to be quickly released into the first fluid chamber through the communication passage and through a pipe line in which an electromagnetic on-off valve are mounted.

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.
