Intelligent wiper system and control method thereof

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;
• and
• 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;
• wherein, when an operation of a predetermined switch is detected while the ignition- on switch is turned off, the controller operates the first and second relays to operate the wiper motor until the operation of the predetermined switch stops.

A wiper system, comprising:

• a wiper motor that operates a wiper;
• a first input device that ouputs 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;
• and
• 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;
• wherein, by the home position returning control signal when an ignition-on switch is turned off during an operation of the wiper motor, the controller maintains the turning on of the first relay for a predetermined period such that a battery power may be supplied to the wiper motor.

A control method for a wiper, comprising:

• determining whether an ignition-on switch is turned off while a wiper is operated at a selected mode;
• outputting a home position returning control signal of a wiper when the ignition-on switch is turned off;
• and
• returning the wiper to a home position by supplying a battery power to the wiper motor by maintaining turning on of a first relay for a predetermined period in response to the home position returning control signal.

A control method for a wiper, comprising:

• determining whether an operation of a predetermined switch is detected while an ignition-on switch is turned off;
• operating first and second relays to operate the wiper by outputting a stopping control signal, when the operation of the predetermined switch is detected;
• and
• stopping the wiper at a present position by stopping the operation of the first and second relays when the operation of the predetermined switch is stopped during the operation of the wiper motor.

A control method of a wiper comprising:

• determining whether an ignition-on switch is turned off while a wiper is operated at a selected mode;
• determining whether a predetermined signal is produced by a remote door controller when the ignition-on switch is turned off while the wiper is operated at the selected mode;
• outputting a home position returning control signal when the predetermined signal is produced by a remote door controller;
• and
• returning the wiper to a home position by supplying a battery power to the wiper motor by maintaining turning on of a first relay for a predetermined period in response to the home position returning control signal.

A control method of a wiper comprising:

• determining whether a door unlock signal is produced by a remote door controller while an ignition-on switch is turned off;
• operating first and second relays to operate the wiper by outputting a wiper operating signal, when the door unlock signal is produced;
• and
• stopping the outputting of wiper operating signal so as to stop the operation of the first and second relays such that the wiper motor is returned to its home position, when the operation of the wiper motor is executed for more than a predetermined period.
