Abstract

Environmental hazards and safe conditions can be indicated to an operator of a vehicle. An audio signal of varying intensities can be played to indicate the severity of a potential hazard. An audio signal can be played at different locations in the vehicle cabin to indicate the location of a potential hazard. Surfaces such as but not limited to windows can be tinted to indicate a hazardous or safe condition. Tinting can be of various intensities commensurate with a potential hazard. Location of tinting can indicate the location of a potential hazard.

Claims

1. A vehicular system comprising:

at least one computing device having at least one processor and also having a memory; and

at least one module having a portion loaded into the memory causing the at least one processor to;

receive data from at least one sensor of a vehicle;

cause the data from the at least one sensor to be analyzed; and

provide at least one tinted surface of the vehicle as a visual indication warning to a driver by tinting at least one surface of the vehicle in response to detecting a condition based at least in part on the analyzed data,

wherein the tinted surface comprises a windshield, a window, or a mirror,

and wherein the condition that is visually indicated by tinting the surface includes at least one of the following detected conditions;

an unsafe lane change condition, a safe lane change condition, an unsafe merge condition, a safe merge condition, an approaching turn, an approaching exit.

2. The vehicular system of claim 1, wherein the at least one tinted surface of the vehicle comprises at least one of the following:

an operator'"'"'s side window, a mirror.

3. The vehicular system of claim 1, wherein the at least one tinted surface of the vehicle comprises at least one of the following:

a surface that is backlit, a surface that is reflective.

4. The vehicular system of claim 1, wherein the at least one tinted surface of the vehicle comprises at least one of the following:

a surface tinted with a color indicating that the condition is a safe condition, a surface tinted with a color indicating that the condition is a hazard condition.

5. The vehicular system of claim 1, wherein the at least one tinted surface of the vehicle comprises at least one of the following:

a green tinting to indicate a safe condition, or a red tinting to indicate a potentially hazardous condition.

6. The vehicular system of claim 1, further comprising at least one LED which is positioned in the vehicle to tint a window by shining through the window, thereby providing the visual indication of the condition.

7. The vehicular system of claim 1, wherein the module resides within the vehicle, the module analyzes at least a portion of the data from the at least one sensor, and the module is modifiable by downloading from a wireless network.

8. The vehicular system of claim 1, comprising a vehicle computing device within the vehicle and also comprising a cloud computing device which is remote from the vehicle and includes a cloud computing device processor and a cloud computing device memory, and wherein the at least one module of the vehicle computing device has a portion loaded into the memory within the vehicle which causes the vehicle computing device to receive information from the cloud computing device.

9. A method for indicating an external condition to an operator of a vehicle, the method comprising:

receiving, by a processor of a computer of the vehicle, data from a plurality of sensors comprising at least one environmental sensor of the vehicle;

analyzing the data from the plurality of sensors; and

providing at least one tinted surface of the vehicle as a visual indication to warn the vehicle operator of the external condition, said providing step comprising tinting at least one surface of the vehicle in response to detecting the external condition from analyzing the data,

wherein the tinted surface comprises a windshield, a window, or a mirror,

and wherein the external condition that is visually indicated by tinting the surface includes at least one of the following;

an unsafe lane change condition, a safe lane change condition, an unsafe merge condition, a safe merge condition, an approaching turn, an approaching exit.

10. The method of claim 9, wherein the method comprises providing a green window tinting to indicate a safe external condition, and providing a red window tinting to indicate a potentially hazardous external condition.

11. The method of claim 9, wherein the method comprises altering a tinting intensity in response to at least one of the following:

changes in a degree of hazard of the external condition, changes in an imminence of hazard of the external condition.

12. The method of claim 9, wherein the method comprises progressing a tinting visual indication to a different surface of the vehicle in response to movement of the external condition.

13. The method of claim 9, wherein the method comprises detecting a change in where the operator of the vehicle is gazing, and moving a tinting visual indication to a different surface of the vehicle in response to detecting the change.

14. The method of claim 9, wherein the method further comprises customizing the providing step for a particular operator of the vehicle.

15. A computer-readable storage medium, which is not a communications medium, comprising computer-executable instructions which when executed cause at least one processor of a computing device of a vehicle to:

receive data from a plurality of sensors comprising at least one environmental sensor and at least one operator sensor;

detect an external condition which is identified in a policy, said detection based at least in part on an analysis of data from the plurality of sensors;

provide at least one tinted surface of the vehicle as a visual indication of the external condition, at least in part by tinting at least one surface of the vehicle in response to detecting the external condition,

wherein the tinted surface comprises a windshield, a window, or a mirror,

and wherein the external condition that is visually indicated by tinting the surface includes at least one of the following;

an unsafe lane change condition, a safe lane change condition, an unsafe merge condition, a safe merge condition, an approaching turn, an approaching exit.

16. The computer-readable storage medium of claim 15, comprising further computer-executable instructions, which when executed cause the at least one processor to increase intensity of tinting of at the least one surface of the vehicle to indicate an increasingly hazardous condition, and computer-executable instructions which when executed control an audio signal.

17. The computer-readable storage medium of claim 15, comprising computer-executable instructions, which when executed cause the at least one processor to display the visual indication in a peripheral area of a field of view of an operator of the vehicle.

18. The computer-readable storage medium of claim 15, comprising further computer-executable instructions, which when executed cause the at least one processor to remove the visual indication from a surface at which an operator of the vehicle is looking.

19. The computer-readable storage medium of claim 15, comprising computer-executable instructions, which when executed cause the at least one processor to provide the visual indication on an operator'"'"'s side window of the vehicle.

20. The computer-readable storage medium of claim 15, comprising computer-executable instructions, which when executed cause the at least one processor to provide visual indications in different colors on the at least one surface of the vehicle in response to detecting different external conditions.
