Wiper control
First Claim
1. A method (300) for controlling the movement of a wiper blade (115) over a wiping surface (110), containing the following steps:
- moving (315) the wiper blade (115) across the wiping surface (110) between a lower turning position (UWL) and an upper turning position (OWL);
detecting (320) a request to stop the wiper blade (110);
moving (345) the wiper blade (110) into a lower end position (UEL) and then into a first park position (PL1), if there is a reversing signal; and
stopping (355) the wiper blade (115);
wherein the wiper blade (115) is moved downwards into the lower end position (UEL) after stopping (355) the wiper blade (115), if a low mechanical resistance against the movement of the wiper blade (115) over the wiping surface (110) has previously been determined.

Abstract
The invention relates to a method for controlling the movement of a wiper blade over a wiping surface, including the steps of moving the wiper blade up and down over the wiping surface between a lower turning position and an upper turning position, detecting a requirement to stop the wiper blade, moving the wiper blade downward into a lower end position and from there upward into a first parking position in the event that a reversing signal is present, and stopping the wiper blade. To this end, the wiper blade is moved into the lower end position only if previously thereto low mechanical resistance against the movement of the wiper blade over the wiping surface was determined.

10. A device (100) for controlling the movement of a wiper blade (115) across a wiping surface (110), comprising:
-
a drive (135) which moves the wiper blade (115) across the wiping surface (110) between a lower turning position (UWL) and an upper turning position (OWL); a first input (165) which detects a request to stop the wiper blade (115); a second input (150) which detects a mechanical resistance against the movement of the wiper blade (115) across the wiping surface (110); a control (155), which is configured to control the drive (135) to move the wiper blade (115) into a lower end position (UEL) and from there into a first park position (PL1), if there is a reversing signal; wherein the control (155) is also configured to move the wiper blade (115) into the lower end position (UEL), only if the mechanical resistance is below a predetermined threshold value.
