Abstract

A method for defogging of a vehicle includes: determining whether the defogging of the vehicle is necessary based on at least any one of an outdoor temperature, an operation state of a cooler of an air conditioner, and an operation state of a blower of the air conditioner; defogging to control an air direction mode to add or increase an air volume supplied to a window if it is determined that the defogging of the vehicle is necessary. The air direction mode is maintained in a current state if it is determined that the defogging of the vehicle is not necessary.

First claim

What is claimed is:

1. A method for defogging of a vehicle, comprising steps of:
determining whether the defogging of the vehicle is necessary based on at least any one of an outdoor temperature, an operation state of a cooler of an air conditioner, and an operation state of a blower of the air conditioner;
defogging by controlling an air direction mode to increase an air volume supplied to a window if it is determined that the defogging of the vehicle is necessary; and
maintaining the air direction mode in a current state if it is determined that the defogging of the vehicle is not necessary,
wherein it is determined that the defogging of the vehicle is necessary when the cooler of the air conditioner under the operation state does not operate.

2. A method for defogging of a vehicle, comprising steps of:
determining whether the defogging of the vehicle is necessary based on at least any one of an outdoor temperature, an operation state of a cooler of an air conditioner, and an operation state of a blower of the air conditioner;
defogging by controlling an air direction mode to increase an air volume supplied to a window if it is determined that the defogging of the vehicle is necessary; and
maintaining the air direction mode in a current state if it is determined that the defogging of the vehicle is not necessary,
wherein in the step of determining, it is determined that a defogging condition is satisfied when the outdoor temperature is equal to or less than a preset temperature.

3. The method of claim 2 , wherein in the step of determining, it is determined that a defogging condition is satisfied when the blower of the air conditioner under the operation state has a wind strength value of air equal to or less than a preset strength value.

4. The method of claim 2 , wherein in the step of defogging, if it is determined that the defogging of the vehicle is necessary, the air direction mode is controlled to relatively increase the air volume supplied to the window and to relatively reduce an air volume supplied to other directions.

5. The method of claim 2 , wherein in the step of defogging, if it is determined that the defogging of the vehicle is necessary, the air volume supplied to the window increases and a total air volume supplied from the blower of the air conditioner is maintained.

6. The method of claim 2 , wherein in the step of defogging, if it is determined that the air direction mode is a driver/passenger body mode and the defogging of the vehicle is necessary, the air direction mode is controlled to reduce an air volume supplied to a driver/passenger's body and increase the air volume supplied to the window.

7. The method of claim 2 , wherein in the step of defogging, if it is determined that the air direction mode is a driver/passenger body mode and floor mode and the defogging of the vehicle is necessary, the air direction mode is controlled to reduce an air volume supplied to a driver/passenger's body and a floor and increase the air volume supplied to the window.

8. The method of claim 2 , wherein in the step of defogging, if it is determined that the air direction mode is a floor mode and the defogging of the vehicle is necessary, the air direction mode is controlled to reduce an air volume supplied to a floor and increase the air volume supplied to the window.

9. The method of claim 2 , wherein in the step of defogging, if it is determined that the defogging of the vehicle is necessary, the air direction mode is controlled to increase the air volume supplied to the window, and then, if it is determined that the defogging of the vehicle is not necessary, the air direction mode is controlled to return to an air direction mode prior to the defogging.

10. The method of claim 9 , wherein in the step of defogging, if it is determined that at least one of the outdoor temperature, the operation state of the cooler, and the operation state of the blower does not satisfy a defogging condition, it is determined that the defogging of the vehicle is not necessary.

11. The method of claim 2 , wherein in the step of determining, it is determined whether the defogging of the vehicle is necessary based on at least any one of the outdoor temperature, the operation state of the cooler, the operation state of the blower, and an amount of solar radiation.

12. A non-transitory computer-readable recording medium comprising computer executable instructions execution of which causes the controller to perform the method according to claim 2 .

13. A system for defogging of a vehicle, comprising:
an outdoor temperature sensor configured to measure an outdoor temperature;
a cooler performing cooling;
a blower supplying air;
an air direction controller configured to control an air direction to send the air from the blower to an interior depending on an air direction mode; and
a controller configured to determine whether the defogging of the vehicle is necessary based on at least any one of the outdoor temperature, an operation state of the cooler, and an operation state of the blower, to control the air direction mode of the air direction controller to increase an air volume supplied to a window if it is determined that the defogging of the vehicle is necessary, and to maintain the air direction mode of the air direction controller in a current state if it is determined that the defogging of the vehicle is not necessary,
wherein the controller determines that the defogging of the vehicle is necessary when the cooler of the air conditioner under the operation state does not operate.

14. The method of claim 2 , wherein in the step of determining, it is determined that the defogging of the vehicle is necessary when all of the outdoor temperature, the operation state of the cooler, and the operation state of the blower satisfy a defogging condition.
