Abstract

A wiper system incorporates a wiper motor provided with a wireless interface to provide electric power and control signals to the wiper motor. Thus, a direct electric/signal wire connection to the wiper motor is eliminated. A wireless transmitter may be provided within a first body portion of a vehicle and a wireless receiver and a wiper motor are provided in a second body portion of the vehicle. The second body portion may be moveable relative to the first body portion, such as, for example, a lift gate moving relative to a body opening.

Claims

1. A wiper system comprising:

a wiper motor having an output shaft and a wiper arm coupled to the output shaft for movement therewith;

a first transceiver arranged to provide a wireless electric power signal and a wiper operation control signal; and

a second transceiver wirelessly coupled to the first transceiver to receive the wireless electric power signal and the wiper operation control signal and further being coupled to the wiper motor to provide energizing electric power to the wiper motor such that the wiper motor has a torque producing output to drive at least one wiper assembly, wherein the wiper motor is configured to provide the torque producing output responsive to the wiper operation control signal.

2. The wiper system of claim 1, the first transceiver including a first coil and the second transceiver including a second coil, the wireless electric power signal and the wiper operation control signal being inductively coupled between the first coil and the second coil.

3. The wiper system of claim 1, the first transceiver and the second transceiver operable to communicate the wiper operation control signal with the wireless electric power signal.

4. The wiper system of claim 1, the first transceiver including a first processor and the second transceiver including a second processor, wherein the first and second processors are operable to communicate the wiper operation control signal there between via the first and second transceivers.

5. The wiper system of claim 1, the second transceiver and the wiper motor being integral.

6. The wiper system of claim 1, the second transceiver being coupled to the wiper motor by a wired connection.

7. A vehicle having a body portion including a body opening, the body opening being at least partially enclosed by a transparent body member, a wiper system including a wiper motor driving a wiper element arranged to wipe the transparent body member, the wiper system comprising:

a first transceiver arranged to provide a wireless electric power signal and a wiper operation control signal; and

a second transceiver wirelessly coupled to the first transceiver to receive the wireless electric power signal and the wiper operation control signal and further being coupled to the wiper motor to provide energizing electric power to the wiper motor such that the wiper motor has a torque producing output to drive at least one wiper assembly, wherein the wiper motor is configured to provide the torque producing output responsive to the wiper operation control signal.

8. The vehicle of claim 7, the first transceiver including a first coil and the second transceiver including a second coil, the wireless electric power signal and the wiper operation control signal being inductively coupled between the first coil and the second coil.

9. The vehicle of claim 7, the first transceiver including a first processor and the second transceiver including a second processor, wherein the first and second processors are operable to communicate the wiper operation control signal there between via the first and second transceivers.

10. The vehicle of claim 7, the first transceiver and the second transceiver operable to communicate the wiper operation control signal with the wireless electric power signal.

11. The vehicle of claim 7, the second transceiver and the wiper motor being integral.

12. The vehicle of claim 7, the second transceiver being coupled to the wiper motor by a wired connection.

13. The vehicle of claim 7, wherein the first transceiver is disposed on the body portion and the second transceiver is disposed on the wiper motor.

14. The vehicle of claim 7, the transparent body member being moveable relative to the body opening, the first transceiver being disposed on the body portion and the second transceiver being disposed on the transparent body member.

15. The vehicle of claim 7, a moveable body member enclosing the body opening, the moveable body member having an opening and the transparent body member enclosing the opening.

16. The vehicle of claim 15, the first transceiver being disposed on the body portion and the second transceiver being disposed on the moveable body member.

17. The vehicle of claim 15, the transparent body member being moveable relative to the opening, the first transceiver being disposed on the body portion and the second transceiver being disposed on the transparent body member.

18. The vehicle of claim 17, the transparent body member being moveable relative to the opening, the first transceiver being disposed on the body portion and the second transceiver being disposed on the moveable body member.

19. A method of powering a wiper motor of a wiper system of a vehicle, the method comprising:

providing a first transceiver disposed on a body portion of the vehicle;

providing a second transceiver operatively coupled to the wiper motor; and

wirelessly communicating a wireless electric power signal and a wiper operation control signal from the first transceiver to the second transceiver to energize the wiper motor such that the wiper motor has a torque producing output to drive at least one wiper assembly, wherein the wiper motor is configured to provide the torque producing output responsive to the wiper operation control signal.

20. The method of claim 19, further comprising communicating a data signal in conjunction with the power signal.
