Abstract: A configurable windshield wiper system for a variable sweep angle and/or variable sweep speed. The system includes a bidirectional motor, a gearbox, the gearbox having and input shaft operably coupled to the motor and an output shaft; the gear box configured to ratiometrically step down the number of turns at its output shaft relative to its input shaft; a wiper arm for sweeping a surface of a windshield, the wiper arm operably coupled to an output of the gearbox; and a controller in operable communication with the motor, the controller configured to execute an algorithm to control the position and speed of the motor to achieve a configured sweep angle and configured sweep speed for the wiper arm.
