Abstract
A windshield wiper system (10) which includes an electrical drive motor (12) that makes available a driving moment for at least one windshield wiper (16) performing a back and forth movement on a pane to be cleaned. A signal processing arrangement (20) is provided which, by way of an electrical switching stage (18), controls or regulates the rotation rate of the drive motor (12) to a constant value.
Claims6
A windshield wiper system comprising at least one electrical drive motor that makes available a driving moment for at least one windshield wiper performing a back and forth movement on a pane to be cleaned, and a signal processing arrangement which by way of an electrical switching stage controls the rotation rate of the motor to a constant value, said switching stage determining the operating voltage of the motor as a function of the current flowing through the motor.
Dependencies are inferred from the claim text.
