Abstract

An apparatus for cleaning of a brake disc may include: a processor; and a storage medium in which one or more programs configured to be executable by the processor are recorded, and the one or more programs includes instructions for: a determination unit configured to determine whether a mode change has occurred from a first mode of transporting a shipped vehicle to a second mode of delivering the vehicle to a customer; and a braking controller configured to remove rust generated on a surface of a brake disc by performing braking according to a cleaning mode of the brake disc when it is determined that the mode change has occurred.

First claim

What is claimed is:

1. An apparatus for cleaning of a brake disc, the apparatus comprising:
a processor; and
a storage medium in which one or more programs configured to be executable by the processor are recorded,
wherein the one or more programs includes instructions for:
a determination unit configured to determine whether a mode change has occurred from a first mode of transporting a shipped vehicle to a second mode of delivering the vehicle to a customer; and
a braking controller configured to remove rust generated on a surface of a brake disc by performing braking according to a cleaning mode of the brake disc in response to a determination that the mode change has occurred.

2. An apparatus for cleaning of a brake disc according to claim 1 , wherein the first mode refers to a state in which a power supply path between a battery and a load device is disconnected, and
the second mode refers to a state in which the power supply path between the battery and the load device is connected.

3. An apparatus for cleaning of a brake disc according to claim 1 , wherein the cleaning mode of the brake disc refers to a mode in which braking by hydraulic pressure is performed.

4. An apparatus for cleaning of a brake disc according to claim 1 , wherein in response to detecting a vehicle communication signal for releasing a power cut, the determination unit determines that a mode change has occurred, and
the vehicle communication signal for releasing the power cut is a signal transmitted from a dark current controller configured to control connection or disconnection of a power supply path between a battery and a load device to the load device.

5. An apparatus for cleaning of a brake disc according to claim 1 , wherein in response to detecting an operation signal of a mode change button, the determination unit determines that the mode change has occurred.

6. An apparatus for cleaning of a brake disc according to claim 1 , wherein the braking controller accumulates braking energy and a driving distance of a vehicle during a braking operation of the vehicle, and
when at least one of the accumulated braking energy and the accumulated driving distance exceeds preset values for each of the braking energy and the driving distance, braking according to the cleaning mode of the brake disc is interrupted.

7. An apparatus for cleaning of a brake disc according to claim 6 , wherein the accumulated braking energy and the accumulated driving distance are stored in a non-volatile memory.

8. An apparatus for cleaning of a brake disc according to claim 6 , wherein in response to detecting an operation signal of the cleaning mode stop button, the braking controller interrupts the braking according to the cleaning mode of the brake disc.

9. An apparatus for cleaning of a brake disc according to claim 1 , wherein the braking controller interrupts regenerative braking by a driving motor while performing the braking according to the cleaning mode of the brake disc.

10. An apparatus for cleaning of a brake disc according to claim 1 , further comprising: a display unit configured to displays a notification of performing the braking according to the cleaning mode of the brake disc or a notification of interrupting the braking according to the cleaning mode of the brake disc.

11. A method for cleaning of a brake disc, the method comprising:
a first operation of determining whether a mode change has occurred from a first mode of transporting a shipped vehicle to a second mode of delivering the vehicle to a customer; and
a second operation of removing rust generated on a surface of a brake disc by performing braking according to a cleaning mode of the brake disc in response to a determination that that a mode change has occurred.

12. The method for cleaning of a brake disc of claim 11 , wherein the first mode refers to a state in which a power supply path between a battery and a load device is disconnected, and
the second mode refers to a state in which the power supply path between the battery and the load device is connected.

13. The method for cleaning of a brake disc of claim 11 , wherein the cleaning mode of the brake disc refers to a mode in which braking by hydraulic pressure is performed.

14. The method for cleaning of a brake disc of claim 11 , wherein in response to detecting a vehicle communication signal for releasing a power cut, it is determined in the first operation that a mode change has occurred, and
the vehicle communication signal for releasing the power cut is a signal transmitted from a dark current controller configured to control connection or disconnection of a power supply path between a battery and a load device to the load device.

15. The method for cleaning of a brake disc of claim 11 , wherein in response to detecting an operation signal of a mode change button, it is determined in the first operation that the mode change has occurred.

16. The method for cleaning of a brake disc of claim 11 , further comprising: accumulating braking energy and a driving distance of a vehicle during a braking operation of the vehicle; and
interrupting the braking according to the cleaning mode of the brake disc when at least one of the accumulated braking energy and the accumulated driving distance exceeds preset values for each of the braking energy and the driving distance.

17. The method for cleaning of a brake disc of claim 16 , wherein the accumulated braking energy and the accumulated driving distance are stored in a non-volatile memory.

18. The method for cleaning of a brake disc of claim 16 , further comprising: interrupting the braking according to the cleaning mode of the brake disc in response to detecting an operation signal of the cleaning mode stop button.

19. The method for cleaning of a brake disc of claim 11 , wherein in the second operation, regenerative braking by a driving motor while performing the braking according to the cleaning mode of the brake disc is interrupted.

20. A computer-readable storage medium recording a program for executing the method according to claim 11 on a computer.
