Abstract: In accordance with at least one aspect of this disclosure, a system (100) includes a wiper drive shaft (116) configured to drive a wiper arm (106) between a start position (110) and an end sweep position (112). The wiper drive shaft (116) includes external threads (132) defined therein and at a distal end (134) thereof. An axial length of the external threads (132) along the wiper drive shaft (116) defines the start position (110) and the end sweep position (112), and a total desired sweep angle between the start position (110) and end sweep position (112). The wiper drive shaft (116) includes a first hard stop groove (136) and a second hard stop groove (138), each defined at a respective first axial offset and a second axial offset from the external threads (132) to define a first hard stop position (140) and second hard stop position (142).

Abstract: In accordance with at least one aspect of this disclosure, a system (100) includes a wiper arm (106) configured to sweep along a sweep zone (108) defined between a start position (110) and an end sweep position (112). A wiper drive shaft (116) is operatively connected at a proximal end (118) to the wiper arm to drive the wiper arm between the start position and the end sweep position. At least an angular encoder (120) is operatively connected to a distal end (122) of the wiper drive shaft configured to record an actual position of the wiper arm. A controller (128) is operatively connected to the encoder to receive position wiper arm position data therefrom.
