Abstract
A control device for the driving motor ( ) of a windshield system. A manually operated wiper switch ( ) is provided for selecting an operating mode, in at least one of which the wiper speed is automatically controlled by a characteristic curve and the signal from a rain sensor ( ). To modify the characteristic curve based on the use of the system by an individual driver, the manually operated wiper switch ( ) conveys control commands to an adaptation algorithm control in a control circuit ( ). The control circuit ( ), in response to switching out of the automatic mode, generates a new characteristic curve at a modified operating point, with the new characteristic curve incorporating the modified operating point. When the switching stage which is dependent on the quantity of rain is again activated, the diving motor ( ) is controlled according to the new characteristic curve.
