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.

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.
