Abstract

A wiping system for use on a vehicle window comprises a window wiper assembly positioned proximate the window, a first sensor for detecting the presence of moisture on the window and a second sensor for detecting if the vehicle has been remotely started. A controller is coupled to the wiper assembly and to the first and second sensors and enables the wiper assembly when the vehicle has been remotely started and moisture is present on the window. The wiping system also comprises a third sensor for detecting the presence of moisture on the window, a fourth sensor for detecting vehicle shut-down, and a fifth sensor for sensing the temperature of the window. The controller is coupled to each of the third, fourth, and fifth sensors and enables the wiper assembly when the vehicle has been shut-down for less than a predetermined period of time, the temperature of the window exceeds a temperature threshold, and moisture is detected on the window.

Claims (51)

1. A wiping system for use on a window deployed on a vehicle, said system comprising:

a window wiper assembly positioned proximate said window;

a first sensor for detecting the presence of moisture on said window;

a second sensor for detecting if said vehicle has been started;

a third sensor for sensing ambient temperature;

a fourth sensor for sensing the temperature of said window; and

a controller coupled to said window wiper assembly, to said first sensor, to said second sensor, to said third sensor, and to said fourth sensor for enabling said wiper assembly if said vehicle has been started, moisture is detected on said window, ambient temperature is below a first temperature threshold, and the temperature of said window is above a second temperature threshold.

2. A wiping system according to claim 1 wherein said second sensor determines if said vehicle has been remotely started.

3. A wiping system according to claim 1 further comprising a fifth sensor coupled to said controller for detecting vehicle shut-down.

4. A wiping system according to claim 3 wherein said controller enables said window wiper assembly when said vehicle has been shut-down for less than a predetermined period of time, the temperature of said window exceeds said second temperature threshold, and moisture is detected on said window.

5. A wiping system according to claim 4 further comprising a user input interface coupled to said controller.

6. A wiping system according to claim 5 wherein said controller comprises:

a processor; and

a memory coupled to said processor, said memory storing said predetermined period of time, said first temperature threshold, and said second temperature threshold.

7. A wiping system according to claim 6 wherein said second temperature threshold is approximately the freezing point of water.

8. A wiping system according to claim 7 wherein said wiping system is activated via said user input interface.

9. A wiping system according to claim 7 wherein said vehicle window is a windshield.

10. A wiping system for use on a window deployed on a vehicle, said system comprising:

a window wiper assembly positioned proximate said window;

a first sensor for detecting the presence of moisture on said window;

a second sensor for detecting vehicle shut-down;

a third sensor for sensing the temperature of said window; and

a controller coupled to said window wiper assembly, to said first sensor, to said second sensor, and to said third sensor for enabling said wiper assembly when said vehicle has been shut-down for less than a predetermined period of time, the temperature of said window exceeds a temperature threshold, and moisture is detected on said window.

11. A wiping system according to claim 10 further comprising a fourth sensor coupled to said controller for detecting if the vehicle has been remotely started.

12. A wiping system according to claim 11 further comprising a fifth sensor coupled to said controller for sensing ambient temperature.

13. A wiping system according to claim 11 wherein said controller enables said window wiper assembly if the vehicle has been remotely started and moisture is detected on said window.

14. A wiping system according to claim 13 further comprising a user input interface coupled to said controller.

15. A wiping system according to claim 14 wherein said controller comprises:

a processor; and

a memory coupled to said processor, said memory storing said predetermined period of time and said temperature threshold.

16. A wiping system according to claim 15 wherein said temperature threshold is approximately the freezing point of water.

17. A wiping system according to claim 16 wherein said vehicle window is a windshield.

18. A wiping system for use on a vehicle window, said system comprising:

a window wiper assembly positioned proximate said window;

a first sensor for detecting the presence of moisture on said window;

a second sensor for detecting if the vehicle has been remotely started;

a third sensor for detecting vehicle shut-down;

a fourth sensor for sensing the temperature of said window; and

a controller coupled to said window wiper assembly, to said first sensor, to said second sensor, to said third, and to said fourth sensor for enabling said wiper assembly when moisture is present on said window and said vehicle has been remotely started, and for enabling said wiper assembly when said vehicle has been shut-down for less than a predetermined period of time, the temperature of said window exceeds a temperature threshold, and moisture is detected on said window.

19. A method for wiping a vehicle window utilizing a wiper assembly, said method comprising:

detecting the presence of moisture on said window;

determining if said vehicle has been remotely started;

enabling said window wiper assembly if said vehicle has been remotely started and moisture is present on said window;

detecting vehicle shut-down;

monitoring the temperature of said window; and

enabling said window wiper assembly when said vehicle has been shut-down for less than a predetermined period of time, the temperature of said window exceeds a temperature threshold, and moisture is present on said window.

20. A method for wiping a vehicle window utilizing a window wiper assembly, said method comprising:

tracking the amount of time elapsed after vehicle shut-down;

detecting the presence of moisture on said window;

monitoring the temperature of said window; and

enabling said window wiper assembly when said vehicle has been shut-down for less than a predetermined period of time, the temperature of said window exceeds a temperature threshold, and moisture is present on said window.
