DYNAMIC POSITION FEEDBACK FOR WIPER CONTROL

In accordance with at least one aspect of this disclosure, a system include, a wiper arm configured to sweep along a sweep zone defined between a start position and an end sweep position. A wiper drive shaft is operatively connected at a proximal end to the wiper arm to drive the wiper arm between the start position and the end sweep position. At least an angular encoder is operatively connected to a distal end of the wiper drive shaft configured to record an actual position of the wiper arm. A controller is operatively connected to the encoder to receive positon wiper arm position data therefrom.
