Claim:
A wiper system, comprising: a wiper motor that operates a wiper; a first input device that outputs wiper operation selection information; a controller that controls the wiper motor according to a signal of the first input device and outputs a home position returning control signal when an ignition-on switch is turned off during an operation of the wiper motor; a first relay that supplies a battery power to the wiper motor by being switched on by the home position returning control signal of the controller; a second relay that is disposed between the controller and the wiper motor and operates the wiper motor at an intermittent operation by being switched by a control signal of the controller; a third relay that is disposed between the controller and the wiper motor, and operates the wiper motor at a low speed by being switched by a control signal of the controller; a fourth relay that is disposed between the controller and the wiper motor, and operates the wiper motor at a high speed by being switched by a control signal of the controller; and a second input device that generates a door lock or door unlock signal, wherein the controller operates the first and second relays such that the wiper may return to its home position when the door lock signal is generated by the second input device after the ignition-on switch is turned off.
