Abstract

Systems and methods for automatically removing snow and/or ice from a portion of a vehicle exterior surface are provided. The automatic removal is in response to a determined driving distance or driving time to a destination. The systems include a vehicle navigation unit in communication with a snow removal element. When the navigation unit determines that the current driving distance or driving time to a destination is less than a pre-determined activation point, the frozen precipitate removal element is activated. The systems and methods of the present disclosure can have the benefit of removing snow or ice from a vehicle exterior surface before the vehicle arrives at a destination such as a storage garage, thereby minimizing the deposition of snow or ice at the destination.

Claims (39)

1. A system for removing frozen precipitate from a vehicle exterior surface, comprising:

a navigation unit configured to calculate a current destination arrival interval of the vehicle; and

a removal element, configured to remove accumulated frozen precipitate from at least a portion of the exterior surface, the removal element in communication with the navigation unit,

wherein the removal element is automatically activated when the current destination arrival interval is less than a pre-determined activation point.

2. The system as recited in claim 1 , further comprising a controller configured to:

receive data from a navigation unit pertaining to the current destination arrival interval;

determine whether the current destination arrival interval is less than the pre-determined activation point; and

transmit instructions directing activation of the removal element if the current destination arrival interval is less than the pre-determined activation point.

3. The system as recited in claim 1 , wherein the removal element is automatically deactivated when the current destination arrival interval is less than a pre-determined deactivation point.

4. The system as recited in claim 1 , wherein the current destination arrival interval is a current driving distance to a destination and the pre-determined activation point is a pre-determined driving distance to the destination.

5. The system as recited in claim 1 , wherein the current destination arrival interval is a current driving time to a destination and the pre-determined activation point is a pre-determined driving time to the destination.

6. The system as recited in claim 1 , wherein the removal element comprises any of a radiative element, a conductive heating element, a vibrational removal element, a freezing point lowering element, a mechanical abrasion element, and a mechanical protrusion element.

7. The system as recited in claim 1 , wherein the removal element is located in a wheel well of the vehicle.

8. A method for removing accumulated frozen precipitate from a vehicle exterior surface, the method comprising:

determining a current destination arrival interval of the vehicle; and

activating a removal element when the current destination arrival interval is less than a pre-determined activation point,

wherein the removal element is configured to remove accumulated frozen precipitate from a portion of the vehicle exterior surface when activated, and wherein the current destination arrival interval is a current driving distance to the destination or a current driving time to the destination, and the pre-determined activation point is a pre-determined distance or a pre-determined time, respectively.

9. The method as recited in claim 8 , further comprising:

deactivating the removal element when the current destination arrival interval is less than a pre-determined deactivation point.

10. The method as recited in claim 8 , wherein the determining step is performed by a navigation unit in communication with a global positioning system satellite.

11. The method as recited in claim 8 , wherein the removal element comprises any of a radiative element, a conductive heating element, a vibrational removal element, a freezing point lowering element, a mechanical abrasion element, and a mechanical protrusion element.

12. A system for removing frozen precipitate from a vehicle exterior surface, comprising:

a removal element configured to, when activated, remove accumulated frozen precipitate from a portion of the vehicle exterior surface; and

a controller configured to:

receive data from a navigation unit, the data pertaining to a current destination arrival interval;

determine whether the current destination arrival interval is less than a pre-determined activation point; and

transmit instructions directing activation of the removal element if the current destination arrival interval is less than the pre-determined activation point.

13. The system as recited in claim 12 , wherein the removal element is automatically deactivated when the current destination interval is less than a pre-determined deactivation point.

14. The system as recited in claim 12 , wherein the removal element comprises any of a radiative element, a conductive heating element, a vibrational removal element, a freezing point lowering element, a mechanical abrasion element, and a mechanical protrusion element.

15. The system as recited in claim 12 , wherein the removal element is automatically deactivated when the current destination arrival interval is less than a pre-determined deactivation point.

16. The system as recited in claim 12 , wherein the current destination arrival interval is a current driving distance to a destination and the pre-determined activation point is a pre-determined driving distance to the destination.

17. The system as recited in claim 12 , wherein the current destination arrival interval is a current driving time to a destination and the pre-determined activation point is a pre-determined driving time to the destination.

18. The system as recited in claim 12 , wherein the removal element is located in a wheel well of the vehicle.

19. The system as recited in claim 12 , wherein the navigation unit is an on-board vehicle navigation unit.

20. The system as recited in claim 12 , wherein the navigation unit is an off-board navigation unit.

21. A system for removing accumulated debris from a vehicle exterior surface, comprising:

a navigation unit configured to calculate a current destination arrival interval of the vehicle; and

a removal element, configured to remove accumulated debris from at least a portion of the exterior surface, the removal element in communication with the navigation unit,

wherein the removal element is automatically activated when the current destination arrival interval is less than a pre-determined activation point.
