Abstract: The invention proceeds from a method for operating a wiper device (10) of a vehicle (26), which wiper device has at least one wiper arm (12, 12′) for holding a wiper blade (14, 14′), in particular an aero wiper blade, at least one wiper drive (16) for driving the wiper arm (12, 12′) and at least one computer unit (18) for controlling a wiping movement of the wiper arm (12, 12′) using the wiper drive (16), wherein the computer unit (18) has a memory unit (20) in which a park position (22), which is associated with a position of the wiper drive (16), is stored.
The invention proposes that the computer unit (18) corrects the park position (22) as a function of a speed of the vehicle (26) in at least one adjustment step (24), wherein a corrected park position (28) lies, in particular in an incident-flow region of the wiper blade (14, 14′).

Abstract: A wiper washer control apparatus includes an ignition sensor, a shift position sensor, a wiper driving unit, a washer spraying unit, a wiper lever detection unit, and a wiper washer control unit. The wiper washer control unit changes a control to be performed by the wiper driving unit to a delay mode when receiving information indicating that the traveling driver is in the started state from the ignition sensor, receiving information indicating that a shift position is in a parking range from the shift position sensor, and receiving information indicating that the delay mode is to be started from the wiper lever detection unit. The wiper washer control unit changes the control to be performed by the wiper driving unit to a spray mode when receiving, in the delay mode, information indicating that the spray mode is to be started from the wiper lever detection unit.

Abstract: Automatic wiper control prohibiting means prohibits execution of automatic wiper control when vehicle stop detecting means detects that a vehicle is stopping and a masking object detecting part determines that a masking object is adhered to an outer surface of a window part. When the vehicle stop detecting means detects that the vehicle is stopping and a state of the masking object detecting part is changed from a state where the masking object detecting part detects that the masking object is adhered to the outer surface of the window part to a state where the masking object detecting part detects that the masking object is not adhered to the outer surface of the window part at a changing time, the automatic wiper control prohibiting means prohibits the execution of said automatic wiper control for a predetermined period of time from the changing time.

Abstract: A windshield wiper system for an aircraft is provided and includes a motor, an output shaft, a wrap spring and crank rocker mechanism (WSCRM) to which the motor and the output shaft are coupled and a controller. By way of the WSCRM, first directional rotation input to the WSCRM from the motor via a two-stage gear reduction is converted such that the output shaft drives wiper blade oscillation through a first sweep angle and second directional rotation input to the WSCRM from the motor is converted such that the output shaft drives wiper blade oscillation through a second sweep angle. The controller is configured to control the motor such that the first directional rotation is continuously or non-continuously input during first or second flight conditions, respectively, and the second directional rotation is continuously input during third flight conditions.
