Abstract: A test system (10) for windshield wipers (18). In one example, the test system has a camera unit (12) which generates image data (B) and captures an image of a windshield wiper (18) moving on a window (16), and an evaluation unit (30) for evaluating the image data (B) with respect to a wiping frequency and/or an objective wiping quality. A test method for windshield wipers (18) is also proposed. The method includes aligning the camera unit (12) with a field of vision (14) of a window (16), image data (B) are generated, and a wiping frequency of the windshield wiper (18) is then determined and/or a wiping quality of the windshield wiper (18) is determined by means of an evaluation unit (30). The wiping frequency and/or key figures of the wiping quality is/are output in a display (34).

Abstract: In the method for controlling at least one washing device of at least one sensor situated on an outer contour of a vehicle, a completed vehicle wash of the outer contour of the vehicle is initially recognized. In this case, “sensors,” for example, are distance sensors, which detect the surroundings of a vehicle and are situated for this purpose on the outer body of the vehicle. As a result of a completed vehicle wash, the externally mounted sensors are cleaned as well and, therefore, after a vehicle wash, it may be assumed that these sensors are now free of dirt. First control signals for actuating the at least one washing device of the at least one sensor are generated depending on a recognized vehicle wash, which was carried out, for example, in a car wash.

Abstract: The invention relates to a wiper device comprising at least one wiper drive (10) which is provided for driving a wiper arm (12) over a wiping region (14) of a vehicle window (16) in a direction-changing manner and comprising at least one control and/or regulating unit (18) which is provided for actuating the at least one wiper drive (10) in order to move the wiper arm (12) between a first wiping region boundary (20) and a second wiping region boundary (22). The wiper device comprises at least one interface (24) which is provided for establishing communication between the control and/or regulating unit (18) and an external end user unit (26), wherein the external end user unit (26) is provided at least for adjusting the first wiping region boundary (20).

Abstract: A method is disclosed for detecting the activation of a coupling in a damper actuator, the coupling engaging a drive motor and an adjustable damper with each other, so that the damper can be adjusted by means of the drive motor, and the engagement between the drive motor and the damper being disengaged if a force or a momentum acting on the damper exceeds a maximum value. The method comprises the following steps: detecting the indication of an adjustment rate, in particular a rotary speed of the drive motor; determining a gradient of the adjustment rate, in particular a rotary speed gradient, by the indication of the adjustment rate; determining the activation of the coupling by determining whether the determined gradient exceeds or falls below a predetermined threshold value of the gradient.
