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.
Claims19
A control device (160) for controlling a drive unit (120) for at least one wiper arm (140) of a vehicle windshield wiper system (100), the control device (160) being designed to determine at least one load variable (L) of the drive unit (120) and to set the wiping frequency (WH) of the wiper arm (140) on the basis of a ratio of the determined load variable (L) to at least one load threshold value (LS), characterized in that the control device (160) is designed to perform the setting of the wiping frequency (WH) depending on a present traveling velocity (v) of the vehicle.
A windshield wiper system (100) for a vehicle comprising a drive unit (120) for at least one wiper arm (140) and a control device (160) for the drive unit (120), the control device (160) being designed to determine at least one load variable (L) of the drive unit (120) and to set a wiping frequency (WH) of the wiper arm (140) on the basis of a ratio of the determined load variable (L) to at least one load threshold value (LS), characterized in that the control device (160) is designed to perform the setting of the wiping frequency (WH) depending on a present traveling velocity (v) of the vehicle.
A method for controlling a drive unit (120) of a windshield wiper system (100) of a vehicle having at least one wiper arm (140), at least one load variable (L) of the drive unit (120) being determined, and a wiping frequency (WH) of the wiper arm (140) being set on a basis of a ratio of the determined load variable (L) to at least one load threshold value (LS), characterized in that the setting of the wiping frequency (WH) takes place depending on a present traveling velocity (v) of the vehicle.
