Abstract

Vehicle horn functions are implemented by deriving a current value associated with a component defined by a policy, retrieving from a data file a volume setting mapped to the current value, and modifying operation of a horn in a vehicle to produce a volume corresponding to the volume setting when an operator of the vehicle activates the horn.

Claims

1. A method for implementing vehicle horn functions, comprising:

deriving, via a computer processor in a vehicle, a current value associated with a component defined by a policy;

retrieving, from a data file, a volume setting mapped to the current value; and

modifying operation of a horn in the vehicle to produce a volume corresponding to the volume setting when an operator of the vehicle activates the horn.

2. The method of claim 1, wherein the component is time of day and the logic receives the current value from a clock in the vehicle over a vehicle network.

3. The method of claim 2, further comprising:

deriving another current value associated with another component defined by another policy;

retrieving, from another data file, a volume setting mapped to the other current value; and

upon determining the volume setting mapped to the other current value is different than the volume setting mapped to the current value, selecting one of the volume setting mapped to the other current value and the volume setting mapped to the current value for modifying the operation of the horn.

4. The method of claim 3, wherein the other component is a geographic location and the logic receives the other current value from a global positioning system device in the vehicle over the vehicle network.

5. The method of claim 1, wherein the component is a geographic location and the logic receives the current value from a global positioning system device in the vehicle over a vehicle network.

6. The method of claim 1, further comprising:

downloading the policy, via a communications component and the computer processor, over a network.

7. The method of claim 1, wherein the volume setting is a lowest defined volume of the horn, the method further comprising:

activating external lights on the vehicle when the horn is activated.

8. The method of claim 1, wherein the operation of the horn is modified to a lower volume setting via a muffler device communicatively coupled to the computer processor over a vehicle network.

9. A computer program product for implementing vehicle horn functions, the computer program product comprising a computer-readable storage medium embodied with instructions, which when executed by a computer processor of a vehicle cause the computer processor to implement a method, the method comprising:

deriving a current value associated with a component defined by a policy;

retrieving, from a data file, a volume setting mapped to the current value; and

modifying operation of a horn in the vehicle to produce a volume corresponding to the volume setting when an operator of the vehicle activates the horn.

10. The computer program product of claim 9, wherein the component is time of day and the logic receives the current value from a clock in the vehicle over a vehicle network.

11. The computer program product of claim 10, wherein the method further comprises:

deriving another current value associated with another component defined by another policy;

retrieving, from another data file, a volume setting mapped to the other current value; and

upon determining the volume setting mapped to the other current value is different than the volume setting mapped to the current value, selecting one of the volume setting mapped to the other current value and the volume setting mapped to the current value for modifying the operation of the horn.

12. The computer program product of claim 11, wherein the other component is a geographic location and the logic receives the other current value from a global positioning system device in the vehicle over the vehicle network.

13. The computer program product of claim 9, wherein the component is a geographic location and the logic receives the current value from a global positioning system device in the vehicle over a vehicle network.

14. The computer program product of claim 9, wherein the method further comprises:

downloading the policy over a network.

15. The computer program product of claim 9, wherein the volume setting is a lowest defined volume of the horn, the method further comprises:

activating external lights on the vehicle when the horn is activated.

16. The computer program product of claim 9, wherein the operation of the horn is modified to a lower volume setting via a muffler device.
