Abstract: A braking device for a vehicle and a method of controlling a braking device for a vehicle are disclosed. The present disclosure in at least one embodiment provides a method of controlling a braking device for a vehicle having a first wheel brake, a second wheel brake, a third wheel brake, and a fourth wheel brake for vehicle braking, including determining whether a first braking unit operates normally upon determining that a braking situation has occurred while driving the vehicle, and braking the vehicle, upon determining that the first braking unit fails to operate normally, by supplying hydraulic pressure to the third wheel brake and the fourth wheel brake by operating a second braking unit, and preventing wheel locks of a first wheel and a second wheel provided on the vehicle by opening a pressure-reducing valve upon determining that a driver has intervened in the braking situation.

Abstract: A braking apparatus for a vehicle and a method for controlling the same. The braking apparatus includes a master cylinder configured to form braking pressure based on an input to a brake pedal and transmit the braking pressure to a wheel brake side, a motor configured to control the pressure transmitted to the wheel brake side by moving a piston included in the master cylinder, and a controller configured to control the motor. The controller determines whether the piston reaches an end point of travel, based on a rate of change in a position of the piston and a current of the motor, and sets a displacement of the piston as a maximum displacement when it is determined that the piston has reached the end point and position initialization for the piston has been completed.

Abstract: Disclosed is a method of controlling an electronic stability control (ESC) integrated braking system, which includes, when a failure in which pressure is unable to be formed in a master cylinder unit is detected during braking of a vehicle by the ESC integrated braking system, maintaining, by a controller, a braking force applied during the braking by closing designated oil pressure relief valves for coupling the master cylinder unit and a flow channel of a circuit, and when pressure (PC1) of a pedal cylinder becomes equal to or greater than pressure (MC1) of the circuit based on the maintained braking force, by a brake pedal stepped on by a driver, controlling, by the controller, the designated oil pressure relief valves to be in an open state and then switching the state of the designated oil pressure relief valves to a mechanical backup state.

The apparatus includes: a pedal cylinder unit connected with a reserve unit in which oil is stored and configured to generate an oil pressure as a brake pedal is pressed; a motor driven by an electric signal that is output in response to displacement of the brake pedal; a master cylinder unit connected with the pedal cylinder unit; a control unit configured to perform reverse pressure control on the motor as much as a variation in a rear-wheel regenerative braking force if transition of the rear-wheel regenerative braking force occurs, and perform drive pressure control on the motor if the transition of the rear-wheel regenerative braking force is completed; and oil pressure relief valves provided on oil pressure lines that connect from the reserve unit to wheel cylinders.

Abstract: An apparatus for controlling an ABS of an ESC integrated brake system and a method thereof. The apparatus includes a main master cylinder generating hydraulic brake pressure through a piston that is moved forward/backward by an actuator that is operated when a brake pedal of a vehicle is pressed down; and a controller controlling forward/backward movement direction change of the piston by controlling a driving current that is applied to the actuator by determining whether a direction change condition according the control state of wheel pressure is satisfied, when a brake mode of the vehicle is an ABS mode and the piston has reached a predetermined direction change position for forward/backward movement direction change.

When an anti-lock brake system (ABS) starting pressure is lower than an ABS critical value, the controller performs a low-pressure forward movement connection control that closes the first traction control valve and the second traction control valve, and moves the main piston forward to increase a first hydraulic pressure in the second main chamber.
