DYNAMIC SWEEP ANGLE MEASUREMENT FOR FAULT MONITORING OF WINDSHIELD WIPER SYSTEMS

A windshield wiper system (WWS) (101) is provided and includes a wiper blade assembly (120) drivable along a first sweep angle, an internal wiper trigger disposed to move with the wiper blade assembly, a measurement system configured to monitor a position of the internal wiper trigger (140) from which a corresponding position of the wiper blade assembly relative to the first sweep angle is measurable and to output a sweep angle feedback signal corresponding to monitoring results and a controller. The controller (131) is receptive of the sweep angle feedback signal.
