Abstract

The device for controlling automatic operation of a windshield wiper in a motor vehicle includes a central electronic control unit provided with means for triggering wiping operations of the windshield wiper; a rain sensor including a detector for rain on the windshield and a device for generating sensor signals for the triggering of individual wiping operations according to detector response, which is connected to the control unit in order to furnish the sensor signals to the control unit, and a sensitivity control device for adjusting rain sensor sensitivity, which includes a display device for observing the rain sensor sensitivity or parameters controlling it optically and buttons operable to adjust the rain sensor sensitivity or at least one of the parameters controlling it.
