Abstract

The present technology includes a washer system comprising a washer switch assembly and an electronic module. The washer switch includes a ground configured for electrical connection with a washer pump by way of a switch and a fuse contact configured to receive control signals from a power-mode relay. The electronic module includes a controller comprising a computer-readable storage device, and the controller is electrically isolated from the washer switch assembly and the washer pump in operation of the system.

First claim

What is claimed:

1. A washer system comprising:
a washer switch assembly comprising:
a ground configured for electrical connection with a washer pump by way of a switch; and
a fuse contact configured to receive control signals from a power-mode relay; and

an electronic module including a controller comprising a computer-readable storage device, the controller electrically isolated from the washer switch assembly and the washer pump in operation of the system.

2. The system of claim 1 , wherein the computer-readable storage device comprises instructions that, when executed by a processor, cause the processor to receive and process an input signal from the washer switch assembly based on predetermined logic criteria.

3. The system of claim 1 , wherein the computer-readable storage device comprises instructions that, when executed by a processor, cause the processor to communicate an output signal to the power-mode relay based on predetermined logic criteria.

4. The system of claim 3 , wherein the output signal includes data instruction for the fuse contact to reduce or eliminate voltage to the washer pump.

5. The system of claim 1 , wherein the washer switch assembly further comprises a signal-status contact configured for electrical connection with a resistor.

6. The system of claim 5 , wherein the resistor comprises a resistor ladder.

7. The system of claim 5 , wherein the electronic module is a first electronic module configured to communicate control signals to the power-mode relay and a second electronic module is configured to communicate controls signals to the resistor.

8. The system of claim 7 , wherein the second electronic module is in communication with the first electronic module.

9. The system of claim 1 , wherein the washer switch assembly further comprises an axle in electrical connection which the fuse contact and switching mechanism for the ground.

10. A washer system comprising:
a relay box having a power-mode relay;
a washer pump;
a washer switch assembly comprising:
a ground configured for electrical connection with the washer pump by way of a switch; and
a fuse contact configured to receive control signals from the power-mode relay; and

an electronic module including a controller comprising a computer-readable storage device, the controller electrically isolated from the washer switch assembly and the washer pump in operation of the system.

11. The system of claim 10 , wherein the computer-readable storage device comprises instructions that, when executed by a processor, cause the processor to receive and process an input signal from the washer switch assembly based on predetermined logic criteria.

12. The system of claim 10 , wherein the computer-readable storage device comprises instructions that, when executed by a processor, cause the processor to communicate an output signal to the power-mode relay based on predetermined logic criteria.

13. The system of claim 12 , wherein the output signal includes data instruction for the fuse contact to reduce or eliminate voltage to the washer pump.

14. The system of claim 10 , wherein the washer switch assembly further comprises a signal-status contact configured for electrical connection with a resistor.

15. The system of claim 14 , wherein the resistor comprises a resistor ladder.

16. The system of claim 14 , wherein the electronic module is a first electronic module configured to communicate control signals to the power-mode relay and a second electronic module is configured to communicate controls signals to the resistor.

17. The system of claim 16 , wherein the second electronic module is in communication with the first electronic module.

18. A washer system comprising:
a washer switch assembly comprising:
a ground configured for electrical connection with a washer pump by way of a switch;
a fuse contact configured to receive control signals from a power-mode relay;
a signal-status contact configured for electrical connection with a resistive ladder;
a resistor configured for electrical connection with the resistive ladder and the signal-status contact; and

an electronic module including a controller comprising a computer-readable storage device, the controller electrically isolated from the washer switch assembly and the washer pump in operation of the system.

19. The system of claim 18 , wherein the computer-readable storage device comprises instructions that, when executed by a processor, cause the processor to receive and process an input signal from the washer switch assembly based on predetermined logic criteria.

20. The system of claim 18 , wherein the computer-readable storage device comprises instructions that, when executed by a processor, cause the processor to communicate an output signal to the power-mode relay based on predetermined logic criteria.
