ABSTRACT:
A windshield wiper control system improves vehicle windshield wiper operation by selectively controlling the motor speed of a dc motor that drives the wiper blade across the windshield. The motor speed is reduced for a portion of the wiper pattern adjacent the reversal points at each end of the wiper pattern. The motor speed is changed as a function of blade position by varying the duty cycle of an excitation voltage signal provided to a variable speed dc motor. The disclosed embodiment is useful for variable and continuous speed control in a vehicle wiper system.
