Abstract

The invention relates to a control device (160) for a drive unit (120) of a vehicle windshield wiper system (100) comprising at least one wiper arm (140). The control device (160) is designed to determine a load quantity (L) of the drive unit (120) and to set the wiping frequency (WH) of the wiper arm (140) on the basis of the ratio of the load quantity (L) to at least one load threshold value (LS). Furthermore, the control device (160) is designed to set the wiping frequency (WH) depending on the current speed (v) of the vehicle.
