Abstract: The braking device for a vehicle includes a judging portion which judges whether the input piston and the output piston are in contact with or separated from each other and a control portion which outputs the control signal to the pilot pressure generating device so that the hydraulic pressure detected by the hydraulic pressure detecting device becomes a target value corresponding to a vehicle state, when judged that the input piston is not in contact with the output piston and outputs another control signal to the pilot pressure generating device, by which the pilot pressure becomes higher than the pilot pressure generated under a same vehicle state to a vehicle state in a case that the control signal is outputted when the judging portion judges that the input piston is not in contact with the output piston, when judged that the input piston is in contact with the output piston.

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: In a vehicular brake device, while a brake operating member is not operated and a wheel cylinder pressure supplying control is executed to supply the target wheel cylinder pressure to the respective wheel cylinders individually, the vehicle control device sets the target servo pressure to a first predetermined target servo pressure which is a value smaller than a maximum output pressure of the servo pressure generating device. When the execution of the wheel cylinder pressure supplying control starts, the vehicle control device sets the target servo pressure to be the target wheel cylinder maximum value when a firstly occurred rising inclination of the target wheel cylinder maximum value is equal to or more than a minimum increment of an output of the servo pressure generating device per unit time and at the same time when the target wheel cylinder pressure is smaller than the first determined target servo pressure.
