A device is described for controlling the operation of an electric motor for driving the arm of a windshield wiper of an opening window, particularly the rear window of an automotive vehicle. The device has a control unit for supplying power to the motor. The operation of the motor is controlled by a key contact of the vehicle and a control element. The key contact and the control element are under user control and are connected in series between a power supply source, the control unit, and a contact for detecting the opening or closing of the window. The device is further characterized in that the open window detection contact is connected to a control unit data input so that it controls restarting the motor only after opening and closing of window and only after reinitialization of the control element by interruption of the control element and by a new user action on the control element.
A device for controlling the operation of an electric motor driving the arm of a windshield wiper for an opening window of an automotive vehicle, of the type comprising a power supply, a control element for selectively activating and deactivating the operation of the motor through deactivating the motor and subsequently activating the motor for a new use thereof, a control unit having a data input for inhibiting the power supply to the motor, a key contact for keeping the operation of the vehicle and said control element under user control, said key contact being connected in series between said power supply and said control unit, a detection contact for responding to the open and closed position of the window, said detection contact being connected to said control unit data input, said data input commanding the restarting of the motor on opening and closing of the window and only after said control element deactivation and subsequent activation of the motor for a new use thereof.
A device for controlling the operation of an electric motor driving the arm of a windshield wiper for an opening window of an automotive vehicle, of the type comprising a power supply, a control element for selectively activating and deactivating the operation of the motor through activating the motor and subsequently reactivating the motor for a new use thereof, a control unit having a data input for inhibiting the power supply to the motor, a key contact for keeping the operation of the vehicle and said control element under user control, said key contact being connected in series between said power supply and said control unit, a detection contact for responding to the open and closed position of the window, said detection contact being connected to said control unit data input, said data input commanding the restarting of the motor on opening and closing of the window and only after said control element deactivation and subsequent activation of the motor for a new use thereof and a power supply terminal of the unit is connected between said key contact and said control element.
A process for controlling the operation of an electric motor for driving the arm of a windshield wiper on opening and closing the window of an automotive vehicle comprising the steps of detecting the open and closed positions of the window and generating a signal in response thereto, commanding through a control unit selective deactivation and reactivation of the motor in response to said opening and closing of the window signal only after deactivating the motor and subsequently reactivating the motor for a new use thereof and generating an inhibiting signal response thereto to selectively inhibit the supply of power to the motor whereby the power supply to the motor is inhibited as soon as the window open signal is received.
