Abstract

An apparatus for tracking the location of a sunroof blind includes: a motor connected to the sunroof blind by a cable; and a controller for determining whether or not a wake-up is performed according to an electromotive force of the motor, and for correcting location information of the sunroof blind according to a determination result.

First claim

What is claimed is:

1. An apparatus for tracking a location of a sunroof blind, comprising:
a motor connected to the sunroof blind by a cable; and
a controller for determining whether or not a wake-up source is generated according to an electromotive force of the motor generated when the cable is moved by an external force in a non-operation state of the sunroof blind, and for correcting location information of the sunroof blind upon determining that the wake-up source is generated according to the electromotive force of the motor,
wherein the controller calculates the location information by adding a setting value to a previously stored location value of the sunroof blind when the wake-up source is the electromotive force of the motor generated by the external force.

2. The apparatus of claim 1 , wherein the controller closes the sunroof blind when a corrected location value of the location information is greater than a reference value.

3. The apparatus of claim 2 , wherein the reference value indicates that the sunroof blind is in an incomplete close state.

4. The apparatus of claim 1 , wherein the controller operates the motor according to an operation command such that the controller determines whether or not the wake-up source is generated by the operation command according to a user's input.

5. The apparatus of claim 1 , further comprising a sensor for sensing an amount of rotation of the motor to generate the location information.

6. The apparatus of claim 1 , further comprising a display device for outputting the location information.

7. The apparatus of claim 6 , wherein the display device displays at least one of graphics, characters, or voices.

8. The apparatus of claim 1 , wherein, when a corrected location value is smaller than a reference value and a number of occurrences, in which the corrected location value is smaller than the reference value, is greater than a reference number, the controller closes the sunroof blind.

9. A method for tracking a location of a sunroof blind, comprising steps of:
determining, by a controller, whether or not a wake-up source is generated according to an electromotive force of a motor that is connected to the sunroof blind by a cable, wherein the electromotive force of the motor is generated when the cable is moved by an external force in a non-operation state of the sunroof blind; and
upon determining that the wake-up source is generated according to the electromotive force of the motor, correcting, by the controller, location information of the sunroof blind,
wherein the controller calculates the location information by adding a setting value to a previously stored location value of the sunroof blind when the wake-up source is the electromotive force of the motor generated by the external force.

10. The method of claim 9 , wherein the controller closes the sunroof blind when a corrected location value of the corrected location information is greater than a reference value.

11. The method of claim 10 , wherein the reference value indicates that the sunroof blind is in an incomplete close state.

12. The method of claim 9 , wherein the controller operates the motor according to an operation command such that the step of determining is executed by the operation command according to a user's input.

13. The method of claim 9 , wherein the location information is generated through a sensor for sensing an amount of rotation of the motor.

14. The method of claim 9 , further comprising a step of outputting the location information to a display device.

15. The method of claim 14 , wherein the step of outputting outputs at least one of graphics, characters, or voices.
