Integrated braking device for vehicle and braking method therefor

An integrated braking device for a vehicle equipped with wheel brakes for braking the vehicle, the integrated braking device comprising:

• a reservoir;
• a master cylinder;
• bi-directional pumps each arranged to use hydraulic pressure oil supplied from the reservoir for generating hydraulic pressure in a first direction to apply a braking force to the wheel brakes or generating hydraulic pressure in a second direction opposing the first direction to control the hydraulic pressure oil from flowing to the reservoir;
• a motor arranged to drive the bi-directional pumps to control the hydraulic pressure oil flowing therethrough;
• inlet valves arranged to control the hydraulic pressure oil from flowing from the bi-directional pumps to the wheel brakes;
• traction control valves each disposed between the master cylinder and each of the bi-directional pumps to control a flow of the hydraulic pressure oil inside the master cylinder;
• and
• a braking control unit configured to perform the braking of the vehicle by transmitting a driving signal to solenoid valves included in the integrated braking device, the bi-directional pumps, and the motor and thereby control a flow of the hydraulic pressure oil,
• wherein the braking control unit is responsive to a turn-on of the vehicle, for closing the traction control valves to prevent the hydraulic pressure oil inside the master cylinder from flowing to the bi-directional pumps.
