Abstract

Disclosed herein are a pressure control apparatus and a pressure control method thereof. The pressure control apparatus includes an input unit configured to receive an input of a current pressure value of a brake apparatus detected by a detection apparatus when drive of the brake apparatus is prepared, a determination unit configured to determine whether the input current pressure value is a preset standard pressure value, and a control unit configured to receive the current pressure value, transfer a determination command to the determination unit, transfer a hydraulic adjustment command to the brake apparatus so that the current pressure value reaches the standard pressure value when the current pressure value is not the standard pressure value, and cause an on/off operation of the brake apparatus to be iterated a predetermined number of times for a predetermined time.

Claims

1. A pressure control apparatus comprising:

an input unit configured to receive an input of a current pressure value of a brake apparatus detected by a detection apparatus when drive of the brake apparatus is prepared, the brake apparatus comprising a motor and a hydraulic valve;

a determination unit configured to determine whether the input current pressure value is a preset standard pressure value;

a control unit configured to receive the current pressure value, transfer a determination command to the determination unit, and control the motor of the brake apparatus to maintain a constant torque of the motor while simultaneously iterating repeatedly on and off operations of the hydraulic valve of the brake apparatus so that the current pressure value reaches the standard pressure value when the current pressure value is not the standard pressure value; and

a first identification unit configured to cause a normal pressure to be identified when the current pressure value is the standard pressure value or cause an abnormal pressure to be identified when the current pressure value is not the standard pressure value.

2. The pressure control apparatus according to claim 1,

wherein the brake apparatus includes a brake pedal and a piston pump, and

wherein the input unit receives the input of the current pressure value output from the piston pump through an operation of the motor according to a braking will of a driver who steps on the brake pedal.

3. The pressure control apparatus according to claim 1,

wherein the determination unit determines whether the input current pressure value is the preset standard pressure value when the current pressure value is provided to the hydraulic valve.

4. The pressure control apparatus according to claim 1,

wherein the control unit transfers a torque generation command corresponding to the hydraulic adjustment command to the motor, transfers a valve operation command to the hydraulic valve while generating a torque of the motor, and repeatedly iterates on and off operations of the hydraulic valve so that the current pressure value reaches the standard pressure value when the current pressure value is not the standard pressure value.

5. The pressure control apparatus according to claim 1, wherein the control unit further transfers a drive command to the brake apparatus so that the brake apparatus is driven when the current pressure value reaches the standard pressure value.

6. The pressure control apparatus according to claim 5, further comprising:

a second identification unit configured to cause the fact that the current pressure value indicates a normal pressure to be identified when the drive command is transferred to the brake apparatus.

7. The pressure control apparatus according to claim 4, further comprising:

an electric charging unit configured to charge an electric charging apparatus with a drive signal corresponding to the torque of the motor when the torque of the motor is generated.

8. The pressure control apparatus according to claim 7, further comprising:

a third identification unit configured to cause a current amount of electric charge to be identified when the electric charging apparatus is charged with the drive signal.

9. The pressure control apparatus according to claim 7, further comprising:

a fourth identification unit configured to cause the fact that electric charging is completed to be identified when the electric charging apparatus is completely charged with the drive signal.

10. The pressure control apparatus according to claim 1, further comprising:

a first selection unit configured to select location information of a desired vehicle maintenance service center from location information of found neighboring vehicle maintenance service centers; and

a drive unit configured to transfer a navigation drive signal to a navigation apparatus for an arrival at the vehicle maintenance service center in correspondence with the selected location information of the vehicle maintenance service center.

11. A pressure control method comprising:

receiving an input of a current pressure value of a brake apparatus detected by a detection apparatus when drive of the brake apparatus is prepared, the brake apparatus comprising a motor and a hydraulic valve;

determining whether the input current pressure value is a preset standard pressure value;

receiving the current pressure value, transferring a determination command to a determination unit, and maintaining a constant torque of the motor while simultaneously iterating repeatedly on and off operations of the hydraulic valve of the brake apparatus so that the current pressure value reaches the standard pressure value when the current pressure value is not the standard pressure value; and

causing a normal pressure to be identified when the current pressure value is the standard pressure value or causing an abnormal pressure be identified when the current pressure value is not the standard pressure value.

12. A pressure control method comprising:

receiving an input of a current pressure value of a brake apparatus detected by a detection apparatus when drive of the brake apparatus is prepared, the brake apparatus comprising a motor and a hydraulic valve;

determining whether the input current pressure value is a preset standard pressure value;

receiving the current pressure value, transferring a determination command to a determination unit, and maintaining a constant torque of the motor while simultaneously iterating repeatedly on and off operations of the hydraulic valve of the brake apparatus so that the current pressure value reaches the standard pressure value when the current pressure value is not the standard pressure value; and

providing a driver with an identification of a normal pressure when the current pressure value is the standard pressure value or an identification of an abnormal pressure when the current pressure value is not the standard pressure value.
