Abstract

A horn activation system for a lightweight utility vehicle can comprises a pressure sensitive horn switch (PSHS) operably connected to a horn button. The horn button is operable with the PSHS such that pressing the horn button compresses the PSHS. The horn activation system additionally can comprise an electronic switching device communicatively connected to the PSHS. The electronic switching device is responsive to a horn activation signal transmitted by the PSHS when the PSHS is compressed in response to depression of the horn button. The horn activation system further can comprise a horn configured to receive a current flow resulting from the electronic switching device closing a horn control circuit upon receipt of the horn activation signal.

Claims (32)

1. A horn activation system for a lightweight utility vehicle, said system comprising:

a pressure sensitive horn switch (PSHS) operably connected to a horn button;

an electronic switching device communicatively connected directly with the PSHS to receive a horn activation signal transmitted directly from the PSHS when the PSHS is compressed to thereby transition the switching device from an open state to a closed state; and

a horn configured to receive a current flow resulting from the electronic switching device closing a horn control circuit upon receipt of the horn activation signal.

2. The system of claim 1 , wherein the horn button comprises a raised formation integrally formed with a vehicle floor mat.

3. The system of claim 1 , wherein the horn button comprises a raised formation molded into a vehicle floor mat.

4. The system of claim 1 , wherein the horn button comprises a raised formation affixed to a vehicle floor mat.

5. The system of claim 1 , wherein the horn button comprises a raised formation integrally formed with the PSHS and extending through an aperture in the floor mat.

6. The system of claim 1 , wherein the horn button comprises a raised formation affixed to the PSHS and extending through an aperture in the floor mat.

7. The system of claim 1 , wherein the PSHS comprises one of a non-contact pressure sensitive switch, a membrane switch, a tape switch, a conductive elastomer type switch or a variable resistance material type switch.

8. The system of claim 1 , wherein the horn control circuit comprises the electronic switching device, a power source and the horn, wherein the electronic switching device completes the horn control circuit upon receipt of the horn activation signal connecting the power source across the horn and causing the current flow through the horn control circuit activating the horn.

9. The system of claim 1 , wherein the electronic switching device opens the horn control circuit when not receiving the horn activation signal so that current does not flow through the horn control circuit and a horn is not activated.

10. A method for activating a lightweight utility vehicle horn, said method comprising:

transmitting a horn activation signal directly from a pressure sensitive horn switch (PSHS) to an electronic switching device when a horn button operably connected to the PSHS is pressed to compress the PSHS; and

transitioning the electronic switching device from an open state to a closed state in response to horn activation signal to close a horn control circuit and provide current to a vehicle horn for activating the horn.

11. The method of claim 10 , wherein transmitting the horn activation signal comprises positioning the PSHS between a vehicle floor structure and a floor mat covering at least a portion of a top surface of the vehicle floor structure.

12. The method of claim 10 , wherein the method further comprises terminating transmission of the horn activation signal when the PSBLS is in a non-compressed state.

13. The method of claim 12 , wherein the method further comprises opening the electronic switching device when transmission of the horn activation signal is terminated to open the horn control circuit such that current flows through the horn control circuit is terminated.

14. A lightweight utility vehicle comprising:

a horn activation system, said horn activation system comprising:

a pressure sensitive horn switch (PSHS) operably connected to a horn button such that depression of a horn button compresses the PSHS; and

a horn control circuit comprising:

a vehicle horn; and

an electronic switching device communicatively connected directly with the PSHS to receive a horn activation signal transmitted directly from the PSHS when the PSHS is compressed to thereby transition the switching device from and open state to a closed state and enable a current flow through the horn.

15. The vehicle of claim 14 , wherein the horn button comprises a raised formation integrally formed with a vehicle floor mat.

16. The vehicle of claim 14 , wherein the horn button comprises a raised formation molded into a vehicle floor mat.

17. The vehicle of claim 14 , wherein the horn button comprises a raised formation affixed to a vehicle floor mat.

18. The vehicle of claim 14 , wherein the horn button comprises a raised formation integrally formed with the PSHS and extending through an aperture in the floor mat.

19. The vehicle of claim 14 , wherein the horn button comprises a raised formation affixed to the PSHS and extending through an aperture in the floor mat.

20. The vehicle of claim 14 , wherein the PSHS comprises one of a non-contact pressure sensitive switch, a membrane switch, a tape switch, a conductive elastomer type switch or a variable resistance material type switch.

21. The vehicle of claim 14 , wherein the horn control circuit further comprises a power source, wherein the electronic switching device completes the horn control circuit upon receipt of the horn activation signal connecting the power source across the horn and causing the current flow through the horn control circuit activating the horn.

22. The vehicle of claim 14 , wherein the electronic switching device opens the horn control circuit when not receiving the horn activation signal so that current does not flow through the horn control circuit and a horn is not activated.
